Memory loss in the elderly should be treated symptomatically according to the cause: first, if the memory is mildly deteriorated due to physiological causes, no special intervention is needed. Secondly, if memory loss in the elderly is caused by Alzheimer’s disease or Lewy body dementia, or vascular dementia due to cerebrovascular disease, the patient should be given medications for symptomatic treatment. For example, patients should be given medications to improve brain metabolism, including Olanzapine capsules, sodium cytarabine tablets, and cerebroprotein hydrolysate tablets, which can improve brain metabolism and enhance memory. Patients can also be given oral medications such as Donepezil hydrochloride and Staphylococcus aureus, which can increase the acetylcholine level in the brain and can improve patients’ memory. The third aspect is that if the elderly have mood disorders, such as anxiety or depression leading to memory loss, it is recommended that patients be given oral Dextran to adjust their mood, and memory loss can be improved.
