There are many neurotrophic drugs, such as vitamin B12, vitamin B1, glutamine, methylcobalamin, adenosylcobalamin, and drugs commonly used for injection, such as pyrithione, aniracetam, and oracetam. Neurotrophic drugs can strengthen the vascular tone of the brain, increase the flow of blood in the brain, promote oxygen supply to the brain, and can relieve hypoxia. It can improve the cortical resistance to hypoxia through the antioxidant effect to achieve brain protection and promote the recovery of nerve cell function. Nerve-nourishing drugs should be taken under the guidance of a doctor. Massage or acupuncture can be performed appropriately to promote the recovery of nerve function, and if the symptoms are severe, further treatment can be given in a hospital.
