Senile dementia mainly refers to Alzheimer's disease, a condition with a relatively high incidence rate among the elderly population, and it is the most common neurodegenerative disease. The specific causes and mechanisms of this disease are not particularly clear. Under the influence of various factors, degeneration and death of the temporal lobe, hippocampus, and neurons occur, leading to a series of clinical manifestations. Initially, it mainly manifests as a decline in recent memory function, often forgetting recent events. As the disease progresses, there is a decline in calculating ability and judgment, significant spatial dysfunction, personality changes, and psychiatric symptoms.
