The cerebrolysin injection derived from purified pig brain proteins, is purported to enhance cognitive function and neuro regeneration. Its effects are thought to involve increased neuronal survival, neuroplasticity, and neurotrophic factor expression. Research suggests potential benefits in Alzheimer’s disease, stroke recovery, and traumatic brain injury, possibly due to its ability to stimulate nerve growth factor and brain-derived neurotrophic factor. However, evidence regarding its efficacy remains mixed, with some studies reporting positive outcomes while others show no significant effects. Common side effects include nausea, headache, and allergic reactions. Further studies are needed to elucidate its mechanisms and establish consistent clinical efficacy.
