The Exciting Frontier of Neuroplasticity: Innovations in Brain Health and Recovery ()
1. Introduction: The Brain’s Superpower-Neuroplasticity in Action
Neuroplasticity, also known as brain plasticity, is the brain’s remarkable ability to reorganize its structure and function by forming new neural connections throughout life. This adaptability enables neurons to adjust their activities in response to intrinsic or extrinsic stimuli, such as learning new skills, recovering from injuries, or adapting to environmental changes. Neuroplasticity encompasses functional changes, like shifting functions from damaged to undamaged brain areas, and structural changes, such as the physical reorganization of neural networks. This dynamic process is essential for learning, memory, and recovery from brain injuries. Additionally, neuroplasticity plays a crucial role in cognitive development, allowing the brain to adapt to new experiences and challenges throughout life. Physical exercise, mental stimulation, and social interactions can enhance neuroplasticity, promoting overall brain health and resilience [1] [2].
Neuroplasticity is crucial for the pathogenesis and treatment of various neurological and psychiatric disorders. It plays a role in the management of neurological disorders like Alzheimer’s disease [3], Parkinson’s disease [4], stroke [5], and traumatic brain injury (TBI) [6], as well as various psychiatric conditions such as depression, anxiety, and Schizophrenia [7]. Alterations in the brain’s structure and function, encompassing synaptic plasticity, dendritic remodeling, neurogenesis, and modifications in neurotransmitter systems, contribute to the progression of diseases and their associated symptoms. Cognitive rehabilitation, physical therapy, pharmacological agents targeting neurotrophic factors [8], and non-invasive brain stimulation techniques [9] are among the strategies aimed at harnessing neuroplasticity to promote recovery, enhance cognitive function, and improve the quality of life for affected individuals [10].
This review aims to deepen the understanding of neuroplasticity by examining the integration of interventions and therapies with advanced neuroimaging techniques, artificial intelligence (AI), and big data analytics to facilitate precision medicine. By exploring these multidisciplinary approaches, the review seeks to elucidate how these technologies can enhance the monitoring and comprehension of neural changes, potentially leading to more effective, personalized therapeutic strategies for neurological conditions.
A mind map illustrating the multifaceted components of brain neuroplasticity is shown in Figure 1.
1.1. Types of Neuroplasticity
Neuroplasticity is categorized into structural, functional, and synaptic plasticity (Figure 1). It encompasses various processes that enable learning, recovery, and adaptation [11] [12]. Structural plasticity involves physical changes in the brain, such as dendritic branching, where neurons develop new dendrites to create additional synaptic connections between the brain cells [13]-[15]. Another key aspect is myelination, the process of strengthening neural pathways by increasing the insulation of myelin sheath around axons, thereby enhancing the speed and efficiency of neural communication [16]. These structural changes improve learning and cognitive performance and support recovery after brain injuries by allowing the brain to reorganize itself and form new pathways in undamaged regions.
Functional neuroplasticity enables the brain to shift functions from damaged

or underutilized areas to healthy regions [17]. This is particularly noticeable in brain injuries such as stroke recovery, where intact parts of the brain can take over tasks previously controlled by damaged areas to compensate for lost abilities, restoring essential functions like speech, motor skills, and cognition.
Synaptic plasticity implies the synapses’ ability to introduce changes in the strength of neuron connections over time in response to activity levels. This process involves both long-term potentiation (LTP), which strengthens synaptic connections through repeated stimulation to enhance learning and memory retention and long-term depression (LTD), which weakens unnecessary synapses, eliminating redundant connections to improve brain efficiency and adaptability [7] [18]. This balancing act between LTP and LTD helps optimize cognitive processing by fine-tuning neural networks, ensuring that only relevant information is retained for learning and memory.
1.2. Processes of Neuroplasticity
Neuroplasticity is a dynamic and continuous adaptation of neural connections that enables the brain to learn, adjust to new experiences, and recover from injuries. Figure 1 shows several critical processes that support neuroplasticity, regulating synaptic connections via formation, strengthening, weakening, and elimination.
Synaptogenesis is the creation of new synapses between neurons, enhancing communication and supporting skill development throughout life [19]. At the same time, synaptic pruning refines neural circuits by eliminating weaker or redundant connections, which continue into adulthood, helping the brain focus on and strengthen essential connections. As previously mentioned, LTP and LTD are opposing yet complementary mechanisms of synaptic plasticity that regulate synaptic strength and play a crucial role in the neuroplasticity process [18]. Axonal sprouting allows neurons to extend new axons to reconnect with other neurons after injury, which is vital for restoring lost functions and re-establishing communication pathways.
These interconnected processes allow the brain to reorganize its structure and function, facilitating cognitive development, skill acquisition, adaptation to new experiences, and recovery from neural damage.
1.3. Mechanisms Involved
Neuroplasticity relies on diverse biological mechanisms that regulate neural adaptation, learning, and recovery [20], as shown in Figure 1. Neurogenesis involves creating new neurons, especially in the hippocampus brain region, which is essential for memory and learning. This process aids in emotional regulation, cognitive flexibility, and recovery from brain injuries by forming new neural pathways. As mentioned earlier, myelination enhances signal transmission by increasing the insulating sheath around axons, improving neural efficiency, accelerating communication between brain regions, and supporting long-term cognitive function [16]. Gene expression plays a crucial role by regulating the production of proteins necessary for synaptic modifications, neuronal growth, and repair, ensuring that neurons can adapt to environmental changes.
Brain-derived neurotrophic factor (BDNF), along with other neurotrophic factors, is necessary for the growth and survival of neurons [21]. They play a significant role in neurogenesis, synaptic plasticity, and overall brain health. Neurotransmitter systems, including chemicals like glutamate, dopamine, and serotonin, regulate neuroplasticity by influencing synaptic changes and affecting mood and motivation. Another essential mechanism is calcium signaling, which plays a crucial role in adjusting synaptic strength. Calcium ions activate pathways that modify connections based on the type and frequency of neural activity, influencing synaptic plasticity and structural remodeling [22]. Dendritic branching involves growing new dendrites, which enhances a neuron’s ability to gather and process information, improving connectivity and playing a crucial role in learning and adapting to new experiences [13] [14].
Together, these interconnected mechanisms drive structural and functional changes in the brain, supporting learning, memory, behavioral adaptation, and injury recovery. By coordinating these processes, the brain continuously evolves in response to experiences, environmental stimuli, and neurodevelopmental changes.
1.4. Factors Influencing Neuroplasticity
Figure 1 presents a range of factors that influence neuroplasticity, shaping the brain’s ability to adapt, learn, and heal. Age is a key factor in neuroplasticity, with the brain being most adaptable in childhood due to higher synaptic density. While neuroplasticity declines with age, the brain remains capable of change throughout adulthood, supporting learning and rehabilitation, albeit at a slower rate [10]. Adequate sleep is crucial, as it helps the brain strengthen and reorganize neural connections, supporting learning and memory. Deep sleep facilitates the pruning of unnecessary connections while strengthening important ones [23]. Good nutrition, including foods rich in omega-3s, antioxidants, and vitamins, also support brain health and new neuron growth [24].
Genetics shape an individual’s baseline capacity for neural reorganization, influencing cognitive abilities and neurological susceptibility. As we age, this capacity declines, making neuroplasticity-driven recovery and adaptation progressively less efficient.
Environmental stimuli, such as enriched surroundings, sensory experiences, and exposure to new challenges, play a crucial role in strengthening neural connections and fostering cognitive flexibility [25]. Social interactions stimulate brain activity, reinforcing emotional regulation, cognitive development, and overall mental well-being. Physical activity enhances neurogenesis and promotes synaptic plasticity by increasing cerebral blood flow and stimulating the release of neurotrophic factors, such as BDNF, which supports neuron survival and connectivity [21].
Pharmaceutical interventions, including medications and targeted therapies, can modulate neural pathways to enhance or restore plasticity, particularly in neurological and psychiatric conditions. Additionally, emotional and behavioral changes, such as stress management, mindfulness practices, and creative activities, contribute to maintaining a healthy and adaptable brain. Cognitive training, which includes problem-solving, learning new skills, and engaging in mentally stimulating tasks, strengthens neural networks and improves cognitive resilience.
These factors shape neuroplasticity, enabling lifelong learning, injury recovery, and adaptation to new experiences.
1.5. Outcomes of Neuroplasticity
The outcomes of neuroplasticity are profound and wide-ranging [11]. It enhances cognitive abilities, such as learning and memory, by forming and strengthening new neural connections (Figure 1). This adaptability is especially valuable after brain injuries, enabling the brain to reorganize and develop new pathways to recover lost functions. One key outcome is enhanced cognitive function, which includes better memory, problem-solving skills, faster information processing, and overall mental agility. This is critical in learning, creativity, and decision-making, allowing individuals to retain and apply knowledge more effectively. Improved motor skills result from strengthened neural connections, leading to better coordination, movement control, and muscle memory, essential for everyday activities and specialized skills such as playing musical instruments or sports.
Neuroplasticity also supports the brain’s ability to adapt to new experiences and environments, facilitating skill development and adjustment [12]. In mental health, it aids in better emotional regulation and helps alleviate symptoms of conditions like anxiety and depression. Additionally, neuroplasticity supports motor skill recovery and coordination, which is crucial for rehabilitation after injuries or in managing chronic conditions such as Parkinson’s disease. These outcomes highlight the brain’s extraordinary capacity to adapt, recover, and thrive, significantly improving cognitive, emotional, behavioral, and physical well-being.
These diverse outcomes highlight the brain’s stunning ability to heal, learn, and evolve, emphasizing the importance of engaging in activities that promote neural flexibility throughout life, such as cognitive training, physical exercise, social interactions, and mindfulness practices.
1.6. Applications of Neuroplasticity
Applications of neuroplasticity are extensive and transformative, as shown in Figure 1. They play a crucial role in aiding recovery from brain injuries, including strokes, by allowing the brain to rewire and regain lost functions such as movement and speech [11]. Neuroplasticity plays a pivotal role in learning and skill development, enabling individuals to acquire new knowledge, adapt to different learning styles, and improve cognitive performance through targeted training. Techniques such as active recall, spaced repetition, and problem-solving exercises strengthen neural connections, making learning more efficient and long-lasting. It also supports cognitive enhancement, allowing individuals to boost memory, attention, and problem-solving skills through brain-stimulating activities such as puzzles, multilingual learning, and music training. These applications extend beyond traditional education, benefiting professionals acquiring new skills and older adults seeking to maintain cognitive health and delay age-related decline [10].
In healthcare, neuroplasticity is fundamental to therapy and rehabilitation, where physical therapy, cognitive exercises, and neurostimulation help patients recover lost functions after brain injuries, strokes, or neurological disorders. Individuals with neurological disorders, such as Parkinson’s disease and Alzheimer’s disease, can undergo targeted therapies that encourage the brain to adapt and manage motor and cognitive challenges.
In mental health, neuroplasticity underpins therapies like Cognitive Behavioral Therapy, which helps rewire negative thought patterns and manage conditions such as anxiety and depression [26]. It also plays a crucial role in skill acquisition, cognitive enhancement through brain training, and the development of assistive technologies. These advancements improve the quality of life for individuals with learning disabilities or neurodevelopmental conditions such as attention-deficit/hyperactivity disorder (ADHD) and autism by fostering adaptive behaviors and enhancing functional outcomes through specialized interventions. For children, neuroplasticity aids in addressing developmental disorders, while for older adults, it helps maintain cognitive health and pause the onset of neurodegenerative diseases [27]. Brain neuroplasticity offers transformative benefits across rehabilitation, mental health, learning, and technological innovations, significantly improving overall well-being and quality of life.
2. Interventions to Enhance Plasticity
Several multifaceted approaches are being employed or developed to halt or reverse the progression of neurodegenerative diseases, with a primary focus on enhancing neuroplasticity through a comprehensive strategy. The therapies specifically target essential processes such as neurogenesis, synaptogenesis, synaptic pruning, long-term potentiation, axonal sprouting, dendritic branching, and myelination (Figure 1).
Modulating neurological conditions involves diverse approaches to manage symptoms, slow disease progression, and enhance brain function, including pharmacological interventions, lifestyle and behavioral changes, neurostimulation, gene and cell-based therapies, and emerging treatments. A brief overview of estimated proportions is provided in Figure 2. As research advances, combining these tailored approaches offers promising outcomes for more effective management of neurological conditions. By focusing on these fundamental mechanisms, the strategy aims to bolster brain resilience, support recovery, and potentially reverse the progression of neurodegenerative conditions. This review will explore key neuroplasticity interventions to enhance brain function and recovery, including medications, gene therapy, lifestyle changes, and non-invasive techniques.
2.1. Pharmacological Interventions
Antidepressants are often prescribed to relieve depression by balancing neurotransmitters like serotonin, norepinephrine, and dopamine in the brain. Beyond depression, they are also used to treat other mood disorders such as anxiety, post-traumatic stress disorder (PTSD), and obsessive-compulsive disorder (OCD), expanding their range of uses. Specific neuroprotective agents and targeted medications can slow disease progression and enhance synaptic plasticity. Their non-invasive nature, convenience, and ability to complement other treatments, such as neurostimulation and behavioral interventions, make them a valuable component of comprehensive care (Figure 2).
Many drugs modulate neurotransmitter systems, such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), which increase serotonin and norepinephrine levels to promote synaptic plasticity and neuronal excitability. Others, like N-Methyl-D-Aspartate (NMDA)

receptor modulators such as ketamine, enhance glutamatergic signaling, increase AMPA receptor trafficking, and reduce excitotoxicity for rapid antidepressant effects [28]. Additionally, neurotrophic factor regulation plays a crucial role, with many antidepressants upregulating BDNF and TrkB signaling to activate pathways like PI3K/Akt and MAPK/ERK, which support neurogenesis and cell survival [21] [29] [30]. Some interventions also target neuroinflammation and oxidative stress, as seen with drugs like minocycline, which mitigate inflammatory responses to preserve synaptic integrity [31]. Emerging epigenetic therapies, including HDAC inhibitors, further influence gene expression related to synaptic plasticity, neurogenesis, and memory formation [32]. These pharmacological strategies enhance neuronal connectivity and functional recovery, making them vital in treating neuropsychiatric and neurodegenerative disorders.
However, these interventions come with limitations, including potential side effects, dependency risks, and systemic toxicity. Many drugs provide only symptomatic relief rather than addressing underlying causes, and long-term use may lead to resistance or tolerance. Individual responses to medications vary due to genetic and metabolic differences, complicating treatment strategies. Furthermore, the high cost and lengthy approval processes for new drugs hinder accessibility and innovation. While pharmacological interventions remain a cornerstone of neuroplasticity-based treatment, their effectiveness is maximized when integrated with other therapeutic approaches while carefully managing risks.
2.1.1. Selective Serotonin Reuptake Inhibitors
Selective serotonin reuptake inhibitors (SSRIs) regulate neurotransmitter activity by stimulating the manifestation of proteins involved in synaptic remodeling, thereby enhancing mood and emotional well-being. Widely prescribed antidepressants in this class, such as fluoxetine (Prozac), sertraline (Zoloft), escitalopram (Lexapro), paroxetine (Paxil, Pexeva), and citalopram (Celexa), are recognized for their ability to increase neuroplasticity [33]. By inhibiting serotonin reuptake, SSRIs elevate its levels in the brain, initiating neurobiological responses. Notably, they promote neurogenesis, particularly in the dentate gyrus of the hippocampus—a process essential for mood regulation and central to the therapeutic effects of SSRIs. Ongoing research into the neurobiological mechanisms of SSRIs holds promise for the development of more efficient treatments for depression and related mood disorders.
2.1.2. Tricyclic Antidepressants
Tricyclic antidepressants (TCAs), although less frequently prescribed today due to their side effects, are experiencing renewed interest in their potential to enhance neuroplasticity. These antidepressants work by inhibiting serotonin and norepinephrine reuptake, increasing their availability and enhancing synaptic plasticity. Research shows that TCAs, such as imipramine, can elevate BDNF levels, a crucial molecule for neuronal growth, survival, and synaptic plasticity [34]. Animal studies have demonstrated that increased BDNF is associated with improved neuroplasticity in brain regions related to mood and cognitive function [35]. This suggests that TCAs may aid in remodeling disrupted neural circuits in depression, potentially leading to enhanced mood and cognitive outcomes. Further research is needed to explore these effects and their implications for depression treatment fully.
2.1.3. Monoamine Oxidase Inhibitors
Monoamine oxidase inhibitors (MAOIs), such as phenelzine and tranylcypromine, are classic antidepressants that function by inhibiting monoamine oxidase, an enzyme responsible for degrading neurotransmitters like serotonin, dopamine, and norepinephrine. This inhibition leads to enhanced levels of these neurotransmitters in the brain. Historically studied for their effects on neurotransmitter regulation, recent evidence suggests that MAOIs may also foster neuroplasticity [36].
MAOIs have been found to affect the activity of neurotransmitter systems implicated in neuroplasticity, such as the serotonin and dopamine systems [37]. However, compared to SSRIs, research investigating the specific effects of MAOIs on neuroplasticity is relatively scarce, and additional studies are needed to clarify the underlying mechanisms and their potential implications for the treatment of depression and other mood disorders. Despite these limitations, the neuroplasticity-promoting effects of MAOIs represent an intriguing area of research that may offer insights into novel treatment approaches for psychiatric conditions.
2.1.4. Cholinesterase Inhibitors
Cholinesterase inhibitors (ChEIs) play a crucial role in preventing the breakdown of acetylcholine through inhibition of the enzyme acetylcholinesterase and have proven effective in treating neurodegenerative illnesses such as Alzheimer’s disease, Parkinson’s disease, and Lewy body dementia. Recent evidence also emphasizes their effectiveness in alleviating depressive symptoms. The Food and Drug Administration (FDA) has approved three ChEIs for clinical use: donepezil (Aricept), rivastigmine (Exelon), and galantamine (Reminyl). Notably, donepezil has demonstrated antidepressant properties in patients with Alzheimer’s disease [38].
2.1.5. N-Methyl-D-Aspartate
N-Methyl-D-Aspartate (NMDA) receptor antagonists play a crucial role in modulating glutamate activity by regulating calcium influx in response to glutamate binding, a process essential for synaptic plasticity and cognitive functions. Excessive activation can lead to excitotoxicity and neuronal damage. Ketamine, a prominent NMDA antagonist, is notable for its rapid antidepressant effects, significantly improving mood within hours by enhancing neuroplasticity and promoting changes in brain circuits related to depression. Thus, ketamine represents a promising option for treatment-resistant depression, highlighting the potential of NMDA receptor modulation in advancing mental health therapies [39].
2.1.6. Neurotrophic Factor Modulators
Modulators target key proteins such as BDNF, nerve growth factor (NGF), and glial cell line-derived neurotrophic factor (GDNF), which play crucial roles in neuron survival via intracellular signaling pathways such as MAPK/ERK and PI3K/Akt [21] [29] [35] [40]. Gene expression, dendritic growth, and synaptic remodeling are promoted through these pathways, playing a crucial role in neuroprotection and cognitive function. These proteins help maintain neuronal health and may slow the progression of neurodegenerative diseases like Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis (ALS) [41]. However, challenges remain in optimizing delivery methods and ensuring long-term effectiveness.
2.2. Advancing Cell-Based and Gene Therapies through Precision Medicine
Cell-based and gene therapy are cutting-edge advancements in precision medicine, offering promising solutions to brain neuroplasticity (Figure 2). Tailoring treatments to each patient’s unique genetic makeup, biomarkers, and advanced technologies such as nanomedicine and AI-based OMICS provides a more personalized and targeted way to promote brain healing and recovery. Many of these therapies are non-invasive, reducing patient burden while expanding therapeutic possibilities.
However, significant challenges remain, including high costs that limit accessibility and affordability. Ethical and regulatory complexities, particularly in gene editing and psychedelics, slow down progress, while concerns over unintended genetic effects, immune responses, and long-term safety require continuous monitoring. The variability in patient response further complicates standardization. While these innovative treatments hold immense promises, ongoing research, regulatory support, and cost-reduction strategies are essential to making them widely available and ensuring their safe and effective integration into clinical practice [42].
2.2.1. Cell-Based Therapies
Stem cell transplants, particularly utilizing neural stem cells (NSCs) and mesenchymal stem cells (MSCs), are at the forefront of regenerative medicine for brain disorders [43] [44]. These cells are designed to replace damaged neurons and foster brain repair by secreting essential neurotrophic factors. These factors support neuronal growth, enhance synaptic plasticity, restore neural functions, amplify neuroplasticity, and facilitate functional recovery.
In Parkinson’s disease, cell-based therapies focus on replacing lost dopaminergic neurons to restore motor function and improve quality of life [45]. For TBI and stroke, NSCs are injected to rejuvenate cognitive and motor functions, drive neural repair, and establish new neural pathways [46]. Alzheimer’s disease treatments involve stem cells that replace lost neurons and mitigate inflammation to enhance cognitive abilities [47]. In ALS, therapies aim to replace damaged motor neurons and offer neuroprotection [41]. Multiple sclerosis is addressed through hematopoietic stem cell therapies that repair neurons and regulate the immune system [48]. Huntington’s disease and spinal cord injuries benefit from stem cell treatments that promote neuron regeneration and functional recovery [49]. Additionally, epilepsy treatments focus on replacing impaired inhibitory neurons to reduce seizure activity, while neurodevelopmental disorders such as autism are being targeted with stem cells to support brain development and neurological function [50]-[52].
2.2.2. Gene Therapies
Gene therapy is revolutionizing the treatment of neurological disorders by directly targeting their genetic causes and enhancing the brain’s repair mechanisms. Cutting-edge gene editing technologies like CRISPR-Cas9 [53] and advanced viral vector systems enable precise interventions to correct genetic abnormalities and boost neuroplasticity. In ALS, gene therapies aim to deliver protective genes like SOD1 to shield motor neurons from degeneration [50]. For Alzheimer’s disease, research focuses on enhancing neuroprotective factors such as BDNF to combat cognitive decline [21]. Spinal muscular atrophy (SMA) is being addressed with innovative treatments like Zolgensma, which supplies a functional SMN1 gene to support motor neuron survival [54]. Additionally, gene therapies are showing promise in Parkinson’s disease by restoring dopamine production [55] and in Batten disease by correcting the defective CLN3 gene [56]. These groundbreaking approaches are transforming the treatment landscape and advocating renewed hope to patients and their families, signaling a new era in the fight against neurological diseases.
2.2.3. Precision Medicine Approach
Precision medicine is reforming neurological disorder treatments by customizing therapies to individual genetic profiles, biomarkers, and personal characteristics. This approach enables patient-specific treatments through genetic sequencing and biomarker analysis, identifying those most benefit from targeted interventions. Personalized gene editing can address unique genetic mutations in neurodegenerative diseases, optimizing patient outcomes.
Clinical trials use genetic data to refine how drugs interact with a person’s unique genetic makeup, ensuring that neuroplasticity-enhancing therapies are more effective and have fewer side effects. Resources like the NINDS Neurogenetics Repository Project provide researchers with DNA samples and clinical information from patients with neurological disorders. By analyzing these genetic insights, scientists can determine which treatments work best for specific individuals, advancing precision medicine. This approach helps tailor therapies to each patient, optimizing drug efficacy while minimizing adverse effects [57]. This strategy promises to transform neurological care by delivering more precise and effective treatments.
2.2.4. Targeting Cellular Processes and Emerging Therapies
Nanoparticles are modernizing the treatment of neurodegenerative diseases by precisely delivering encapsulated small molecules, proteins, and DNA. These particles can cross the blood-brain barrier, allowing targeted central nervous system (CNS) treatments and early diagnosis. In Parkinson’s disease, liposomes and dendrimers deliver neurotrophic factors that protect neurons and alleviate motor symptoms [58]. Alzheimer’s research is advancing with nano-encapsulated antibodies to clear amyloid plaques, potentially slowing cognitive decline [59]. For multiple sclerosis, nanoparticles are being developed to deliver anti-inflammatory drugs directly to the CNS, reducing disease activity with fewer side effects. Additionally, nanoparticle-based therapies are exploring ways to promote nerve regeneration and repair in spinal cord injuries, offering hope for functional recovery [60].
Nanoparticles play a vital role in controlled drug release, enabling sustained therapeutic levels over extended periods and minimizing the need for frequent dosing. They also enhance diagnosis through innovative techniques, such as using gold nanoparticles to detect Alzheimer’s biomarkers and quantum dots to visualize Parkinson’s biomarkers [61]. These advancements contribute to more precise treatments and facilitate more accurate disease detection, representing significant progress in precision medicine.
Researchers are developing therapies that enhance autophagy and mitophagy to protect neurons and slow neurodegenerative disease progression [62]. The primary focus is to target key regulatory pathways such as mTOR (mechanistic target of rapamycin) and AMPK (AMP-activated protein kinase). For example, mTOR inhibitors like rapamycin and AMPK activators like metformin have shown potential in preclinical studies for boosting cellular cleanup and mitigating neurodegeneration in Parkinson’s and Alzheimer’s diseases [63] [64]. Additionally, compounds like spermidine and therapies targeting mitophagy-related proteins, such as PINK1 (PTEN-induced putative kinase 1) and Parkin, aim to improve neuronal survival and function by enhancing the removal of damaged components and supporting mitochondrial quality control [65]. These innovative approaches offer promising new strategies for treating and managing neurodegenerative conditions.
Psychedelics like psilocybin, 3,4-methylenedioxymethamphetamine (MDMA), and lysergic acid diethylamide (LSD) are being explored for their potential in treating neurodegenerative diseases by enhancing neuroplasticity and modulating neurotransmitter systems, particularly serotonin. Clinical trials are investigating their long-term benefits, with early results suggesting potential improvements in cognitive function and overall quality of life for patients with advanced neurodegeneration [66].
Cannabinoids, including cannabidiol (CBD) and tetrahydrocannabinol (THC), are gaining attention for their neuroprotective and anti-inflammatory properties. These compounds intermingle with the endocannabinoid system to modulate immune responses, reduce neuroinflammation, and alleviate oxidative stress, factors critical in neurodegenerative diseases like ALS and Parkinson’s [67].
AI-driven omics—encompassing genomics, proteomics, and metabolomics—are transforming the understanding and treatment of neurodegenerative diseases by providing deep insights into patients’ genetic, protein, and metabolic profiles. AI analyzes large-scale genetic data to identify mutations and genetic markers linked to neurodegeneration, guiding the development of targeted gene therapies and personalized medicine [68].
2.3. Lifestyle and Behavioral Interventions
In recent years, there has been growing interest in leveraging the principles of neuroplasticity within cognitive therapy, rehabilitation, physical activity, and dietary modifications to enhance outcomes for individuals recovering from brain injuries, neurological conditions, or other impairments (Figure 2). It offers a holistic, non-invasive, cost-effective approach to enhancing neuroplasticity and brain health. These interventions are widely accessible and serve as both preventive and rehabilitative strategies, helping individuals recover from brain injuries or neurodegenerative diseases. Additionally, they complement other treatments like neurostimulation, pharmacological therapies, and emerging medical approaches, creating a well-rounded therapeutic framework for neurological care.
However, their effectiveness depends on long-term adherence, which can be challenging for individuals with cognitive impairments or mobility limitations. Unlike pharmacological treatments, lifestyle changes require consistent effort and may take longer to produce noticeable benefits. Effectiveness also varies based on genetics, environmental factors, and access to professional support. While these interventions play a crucial role in brain health, they are often insufficient as standalone treatments for severe neurological conditions, necessitating integration with other medical approaches for optimal outcomes.
2.3.1. Integrating Cognitive, Behavioral, and Physical Therapies for
Comprehensive Neurological Rehabilitation
These approaches comprehensively address the mental, emotional, and physical challenges faced by people with neurological conditions. Combining methods such as retraining the brain to think differently, changing behaviors, and using targeted rehabilitation exercises helps the brain heal and function better, ultimately improving the patient’s quality of life. Cognitive therapy focuses on altering negative thoughts, beliefs, and attitudes, particularly in cases of depression, anxiety, or brain injuries. Techniques like cognitive restructuring help individuals replace negative thoughts with positive ones, while attention and memory training enhance focus and recall. Problem-solving skills teach people to break down complex tasks into manageable steps. Cognitive Behavioral Therapy [26] integrates these methods to address negative thoughts and behaviors tailored for those with brain conditions. Community support is crucial, as well as providing additional resources, encouragement, and social connections that reinforce therapy and foster a supportive environment for recovery.
Behavioral therapy is vital for overcoming harmful habits and behaviors that impact recovery and quality of life, especially for those with disabilities or brain injuries [69]. It helps rebuild lives and promote independence through methods like behavior modification, which uses rewards to reinforce positive behaviors, and exposure therapy, which assists people in facing and overcoming fears related to anxiety, PTSD, or trauma from conditions like strokes. Behavioral activation encourages patients to engage in enjoyable activities to improve mood and rehabilitation outcomes, while habit reversal addresses unhelpful patterns, such as favoring one side of the body after a stroke, by replacing them with more functional behaviors. These therapies provide practical solutions and hope, empowering patients to regain control, with community support playing a vital role in their recovery.
Rehabilitation therapy is focused on restoring physical and cognitive functions lost due to injury, illness, or developmental disorders [70]. It encompasses targeted therapies such as physical therapy for improving movement and coordination, occupational therapy for daily tasks, and speech and language therapy for communication skills. Neuropsychological rehabilitation addresses cognitive functions like memory and problem-solving through personalized plans designed to retrain or compensate for impaired abilities. Successful rehabilitation therapy requires a patient-centered approach, focusing on individual needs and consistent practice to build new neural connections. Advances in telehealth technology are increasingly facilitating remote delivery of rehabilitation services, which is particularly beneficial when in-person therapy is not feasible. Home-based rehabilitation programs and telerehabilitation platforms allow individuals to receive ongoing support from therapists while participating in therapy activities at home [71]. Family, caregivers, and community resources are vital to patient engagement and recovery. Rehabilitation therapy is effective for stroke rehabilitation, TBI recovery, mental health management, and neurodegenerative disease symptom management, providing a comprehensive path to improved functionality and quality of life [72].
2.3.2. Optimizing Neurological Health: The Power of Diet, Exercise, and Lifestyle
Lifestyle interventions, particularly dietary modifications, are crucial for managing neurological conditions and enhancing brain health [23] [24]. A diet rich in specific nutrients can have a profound impact. Incorporating foods such as fatty fish like salmon, mackerel, and sardines, which are high in Omega-3 fatty acids, supports cognitive function and may help protect against neurodegeneration. Berries, including blueberries, strawberries, and blackberries, are rich in antioxidants that reduce inflammation and boost memory. Nuts and seeds, such as walnuts, almonds, and flaxseeds, provide healthy fats and essential nutrients for brain health. Leafy greens like spinach, kale, and collard greens, packed with vitamins and minerals, contribute to cognitive function. Whole grains such as oats, quinoa, and brown rice offer steady energy and support overall brain health, while legumes like beans, lentils, and chickpeas supply fiber and vital nutrients. Cutting back on processed foods, sugary snacks, and unhealthy fats reduces inflammation and prevents symptom progression.
Alongside dietary changes, integrating regular physical activity, such as walking or strength training, enhances brain health by improving blood flow and cognitive function. Adequate sleep is critical for brain recovery and memory consolidation, while effective stress management techniques, including mindfulness and relaxation exercises, help reduce inflammation and prevent cognitive decline. Combining a nutrient-rich diet with regular exercise, proper sleep, and stress management can significantly improve neurological health and overall quality of life [23].
2.4. Non-Invasive Neurostimulation
Brain stimulation methods have been gaining traction due to their ability to alter brain function and foster neuroplastic changes (Figure 2). These techniques are increasingly being explored for their potential applications in manipulating neural activity [73]. Non-invasive and minimally invasive neurostimulation provides a safe and effective method to enhance neuroplasticity without the risks associated with surgical interventions. These techniques are widely applied in treating neurological and psychiatric conditions, supporting stroke recovery, brain injuries, and cognitive enhancement. A key advantage of these approaches is their seamless integration with other therapies, such as cognitive training and pharmacological treatments, to improve patient outcomes. Additionally, advanced imaging tools enable real-time monitoring, allowing for personalized treatment adjustments and optimization of protocols.
Despite its advantages, neurostimulation’s effectiveness varies among individuals, and some benefits may be temporary, requiring repeated sessions to maintain results [74]. The side effects, including headaches, mild discomfort, and potential unintended neural changes, are of great concern. Accessibility is another limitation, as the high cost of specialized equipment and treatment sessions restricts widespread use. Neurostimulation holds immense potential for neurological care, and further research is necessary to enhance long-term efficacy, affordability, and broader clinical implementation.
2.4.1. Transcranial Magnetic Stimulation
Transcranial magnetic stimulation (TMS) involves the non-invasive delivery of brief magnetic pulses to specific brain regions, generating electrical currents that can depolarize neurons and modulate neural activity. In clinical settings, repetitive TMS (rTMS) is FDA-approved for treating depression, particularly in individuals who haven’t responded to traditional antidepressant medications. TMS is being investigated for its potential to treat neuropsychiatric conditions like anxiety disorders, Schizophrenia, and chronic pain [75]. It also serves as a valuable research tool for studying brain function, mapping cortical regions, and exploring the effects of brain stimulation on cognitive processes.
Beyond its research applications, TMS has demonstrated its ability to induce neuroplastic changes in the brain, comprising alterations in cortical excitability, synaptic strength, and connectivity. TMS can facilitate adaptive changes in neural circuits by targeting specific brain regions implicated in various functions. These changes, in turn, lead to improvements in symptoms and cognitive performance, offering promise for enhancing treatment outcomes across a spectrum of neurological and psychiatric conditions [75].
2.4.2. Transcranial Direct Current Stimulation
Transcranial direct current stimulation (tDCS) provides a non-invasive approach to modulating brain activity by utilizing a low-intensity electrical current to the scalp through electrodes. This method adjusts the resting membrane potential of neurons, influencing their firing patterns and overall activity levels.

Variables such as age, genetics, lifestyle factors, and the severity of brain damage significantly impact how well a person responds to specific treatments [24] [89]. These variations make developing one-size-fits-all therapies particularly difficult, as different patients may experience vastly different outcomes. Personalized medicine, which incorporates detailed genetic, epigenetic, and biomarker data, enables the customization of treatments that align with each person’s unique biological profile. This tailored approach increases the likelihood of effective therapeutic outcomes by addressing the patient’s specific needs, genetic predispositions, and overall health circumstances. Such precision optimizes treatment effectiveness and reduces potential side effects, making personalized medicine a cornerstone in advancing brain healing and neuroplasticity research.
However, sustaining these benefits over the long term presents additional challenges. Treatments that initially yield positive results might not always maintain efficacy due to the dynamic nature of brain adaptation and evolving conditions over time. The brain’s needs and responses are not static, so therapies must be continually reassessed to remain effective. This emphasizes the significance of ongoing monitoring and adjustments to treatment protocols. Personalized strategies, which already enhance initial success rates, become even more critical in ensuring long-term improvements in brain health. By adapting treatments to the brain’s changing needs, personalized approaches can help maintain their efficacy and support continuous recovery, ultimately leading to more durable outcomes in neuroplasticity and brain health interventions.
