I. What is dementia in old age: It is mainly age-related and mainly refers to dementia patients over 60 years old. Alzheimer’s disease, vascular disease combined with dementia, dementia caused by vitamin B12 deficiency, dementia caused by hypothyroidism, pseudo-dementia (depression), and others can cause dementia. Second, the process of human memory can be divided into three stages: recording information, storing information, and recalling information. Third, the characteristics of memory Forgetting occurs in everyone, and the brain is deciding every moment what needs to be forgotten and what needs to be remembered. Illness, anxiety and excessive information load can all affect our memory. Most people will become increasingly forgetful as they get older, older people store far more in their memories than younger people, and older people are slower at retrieving memories and absorbing new information. Therefore, only comparisons between people of the same age are meaningful. Fourth, the diagnosis of Alzheimer’s disease relies on detailed medical history and clinical symptoms and signs; relies on various examinations, such as blood routine, blood sugar, serum B12, folic acid, thyroid function, etc. Invest in CT, MRI,
The cognitive scales, such as MOCA, MMSE, Hasegawa scale and other clinical dementia scales, should also be assessed. V. Ten early manifestations of dementia: memory loss, comprehension loss, difficulty with household chores, misplacing things, language problems, emotional or behavioral changes, time and place orientation disorders, personality changes, poor judgment, and loss of initiative. VI. Characteristics of memory decline in normal brain aging Although memory declines, it can still be partially or fully recalled after prompting; cognitive function is basically normal; it basically does not affect social activities, interpersonal interaction, work ability and family life; memory or cognitive scale scores are basically in the normal range or low limit of normal; neuroimaging has elderly brain performance. The purpose of Alzheimer’s disease treatment is to improve symptoms, slow down the progress of the disease, prevent and treat infections, and prevent patients from dying. VIII. Treatment methods Improve cognitive function drugs, symptomatic treatment, strengthen care.
