What is neuroplasticity?
Neuroplasticity is the formal term for the nervous system's capacity to change its structure, connectivity, and function in response to experience, injury, or intervention. Synonyms in the literature include neural plasticity, brain plasticity, and neuroadaptation. It is not a single molecule or pathway; it is a class of processes that includes synaptic remodeling, axonal sprouting, dendritic arborization, myelination changes, and transcriptional reprogramming. Because it is a process rather than a compound, it has no sequence, formula, or molecular weight. Identifiers in the evidence below belong to the specific interventions and models studied, not to neuroplasticity itself.
The work summarized here centers on several receptor and signaling families depending on the model: incretin receptor signaling in metabolic studies, glutamatergic and neurotrophic signaling in neuromodulation and pharmacological studies, and gut-microbiome-derived metabolic signaling in preclinical addiction models.
Research Studies
Incretin therapy and exercise in type 2 diabetes
A randomized clinical trial is examining changes in brain and physical health in adults with type 2 diabetes who are initiating incretin-mimetic therapy, and whether adding structured exercise provides additional benefits. Participants are randomized to incretin-mimetic therapy alone or incretin-mimetic therapy plus a structured exercise program for 24 weeks. Brain health is assessed through cognitive performance, mental health, and brain-mediated appetite measures [1]. This is a human study; results are not yet reported in the evidence block.
Intermittent theta burst stimulation and peripheral biomarkers in treatment-resistant depression
Intermittent theta burst stimulation (iTBS) is a non-invasive neuromodulation technique targeting the left dorsolateral prefrontal cortex. A single-center, prospective, investigator-initiated clinical study aims to investigate the effects of iTBS on clinical symptoms, executive functions, and peripheral inflammatory and neuroprotective biomarkers in treatment-resistant depression [2]. The biological mechanisms underlying treatment response remain poorly understood. This is a human study; results are not yet reported in the evidence block.
Gut Proteobacteria glycine metabolism and cocaine self-administration in mice
In mice, cocaine exposure alters the composition of the gut microbiome, increasing the abundance of Proteobacteria. This microbial shift leads to a depletion in host glycine levels, altering cocaine-induced transcriptional changes in the nucleus accumbens and facilitating the development of behavioral sensitization and reinstatement of cocaine self-administration [3]. This finding is animal-only.
Cerebrolysin as an adjunct to speech-language therapy in post-stroke Wernicke's aphasia: a case report
A case report describes a 38-year-old female lawyer who developed acute Wernicke's aphasia and right-sided hemiparesis following an ischemic stroke. Despite timely thrombolysis and mechanical thrombectomy, she experienced significant neurological deficits. Early multidisciplinary rehabilitation combined with a 10-day course of Cerebrolysin was associated with recovery [4]. This is a single case report; it does not establish efficacy.
Rejuvenation of corticospinal neurons and rehabilitation-associated axon sprouting in mice
Spontaneous recovery following ischemic stroke is often limited, largely attributed to age-related decline in neuroplasticity. In mice, ectopic expression of a cocktail of transcriptional factors (Oct4, Sox2, and Klf4, referred to as OSKTFs) reset developmental decline of epigenetic signatures in adult corticospinal neurons without affecting their spinal projection patterns and function in controlling skilled locomotion. Corticospinal expression of OSKTFs had moderate effects on promoting collateral sprouting of corticospinal tract axons and recovery of skilled motor function following photothrombotic stroke. When combined with task-dependent rehabilitation, effects were enhanced [5]. This finding is animal-only.
Cytokines, neuroplasticity modulators, and biomarkers in spinal canal stenosis and endoscopic decompression
Lumbar spinal stenosis is a common degenerative musculoskeletal disorder characterized by narrowing of the spinal canal, often leading to pain and disability. One of the primary contributors is hypertrophy of the ligamentum flavum, along with facet joint degeneration, intervertebral disc herniation, and ligament ossification. Histological changes in hypertrophied ligamentum flavum include fibrocartilaginous metaplasia, type II collagen proliferation, ossification, calcium crystal deposition, and degeneration of elastic and collagen fibers. A clinical study is investigating cytokines, neuroplasticity modulators, and biomarkers in this context [6]. This is a human study; results are not yet reported in the evidence block.
Cerebrolysin and language ability in non-fluent aphasia after stroke
A randomized, placebo-controlled, double-blinded, single-center study aims to measure changes in language ability after adding Cerebrolysin to standard treatment for non-fluent aphasia patients with post-stroke language impairment. Patients are divided into an experimental group receiving standard treatment (speech therapy) plus Cerebrolysin and a control group receiving standard treatment alone. The study compares PK-WAB scores before and after drug administration [7]. This is a human study; results are not yet reported in the evidence block.
Psilocybin and psilocybin-assisted cognitive behavioral therapy in major depressive disorder
A randomized controlled clinical trial evaluates the effectiveness of psilocybin and psilocybin-assisted cognitive behavioral therapy (CBT) in the management of major depressive disorder. The study compares psilocybin-only therapy, CBT, and psilocybin-assisted CBT on depression symptoms, neurochemical markers, inflammatory markers, and neuroplasticity. Participants continue their routine depression medications and are assessed for changes in depression scores, biochemical markers, and brain activity patterns [8]. This is a human study; results are not yet reported in the evidence block.
