Geriatric brain atrophy is generally not serious, mainly because as people grow older, they will experience deepening of the brain sulcus or widening of the ventricles, and patients can experience memory loss, mostly in the recent memory loss, and the progress of brain atrophy in the elderly is particularly slow, and the impact on the patient’s quality of life is not particularly great. In the case of neurodegenerative diseases, such as Alzheimer’s disease, this kind of atrophy progresses more rapidly, mainly in the temporal lobe hippocampal atrophy, and the patient’s cognitive function declines more obviously, and at a later stage the patient may become unable to take care of himself, unable to dress, eat, and be bedridden, and finally may develop pressure sores or pulmonary infections due to poor nutritional status, and finally die due to infection. The prognosis for senile cerebral atrophy is generally good, the patient’s condition develops slowly, and treatment can be given to improve the metabolism of brain cells, such as brain protein hydrolysate tablets, cytarabine, etc.
