Drugs that nourish the brain nerves include B vitamins, gangliosides, acetylglutamide, olanzapine, calf’s blood deproteinized extracts, and cerebral protein hydrolysates. 1. Vitamin B: such as vitamin B1, vitamin B6, vitamin B12 and its derivative methylcobalamin. 2. Gangliosides: can accelerate the regeneration and repair of damaged nerve tissue, reduce the release of excitatory amino acids, reduce cytotoxicity and vascular edema. 3. Acetylglutamine: It can pass the blood-brain barrier, improve nerve cell metabolism, maintain nerve stress ability and reduce blood ammonia. 4. Olracetam: It is a kind of intellectual stimulant, which is suitable for mild to moderate vascular dementia, Alzheimer’s disease and traumatic brain injury, etc. caused by memory and intelligence disorders, and it has a significant improvement effect on learning and memory disorders caused by chemical substances. 5. Calf serum deprotein: Promote cellular uptake and utilization of glucose and oxygen, improve neurological function damage caused by cerebral blood circulation disorders and nutritional disorders. 6. Brain protein hydrolysate: It acts on the central nervous system through the blood-brain barrier, promotes protein synthesis in brain cells, enhances the ability to resist hypoxia, promotes the formation of synapses, induces the differentiation of neurons, and protects the nerve cells from the damages caused by various kinds of ischemia and neurotoxins. Avoid using drugs on your own, you need a professional doctor to choose the most appropriate type of drug based on the patient’s type of disease, severity, complications and other conditions.
