Hippocampal atrophy is associated with Alzheimer’s disease, which is usually a manifestation of imaging at the time of CT or MRI. The most common cause is Alzheimer’s disease, which is a degenerative brain lesion. Patients mainly show memory loss, cognitive decline, and emotional problems, and may also have some psychiatric symptoms, such as hallucinations and hallucinations. If the patient is diagnosed with hippocampal atrophy, it is very difficult to recover. It is recommended to take oral donepezil, meperidine and other specific therapeutic drugs, as well as some drugs to nourish brain cells and improve the blood supply to the brain, such as cytarabine sodium tablets, olanzapine capsules, aniracetam capsules, piracetam capsules, and some drugs to activate blood circulation and resolve blood stasis, such as ginkgo biloba preparations. Patients should also eat foods rich in lecithin, eat more vegetables and fruits, and use their brains more often to exercise their memory skills.
