Forgetfulness is common in the elderly and is caused by the deterioration of bodily functions. In addition to affecting the daily life of the patient, forgetfulness in the elderly can also lead to the risk of losing the elderly. Therefore, when elderly people have symptoms of forgetfulness, they can adjust their diet, take the initiative to exercise their brain activities and practice to increase their memory capacity to relieve the symptoms of forgetfulness. The elderly can play more chess or mahjong to improve the brain’s consciousness activity and strengthen the function of memory. Patients should usually eat more brain-healthy foods, such as walnuts. If the elderly are forgetful in a more serious way, it is recommended that the patient should visit a hospital in time to improve the cognitive scale assessment and head imaging to clarify whether the patient has Alzheimer’s disease or vascular dementia and give medication in time. If it is considered to be caused by Alzheimer’s disease, give Anlishen orally at an early stage. If it is considered to be vascular dementia, give drugs to improve cerebral arteriosclerosis and give patients treatment to activate blood circulation and improve brain metabolism, such as applying Olacitant capsules, cytarabine sodium tablets, nimeglumine, etc.
