Why do elderly people suddenly lose their memory?

Ask
Hello doctor. Because of an incident that made her too worried and scared, it led to suddenly forgetting most of the surrounding things, only remembering some things but not exactly. The doctor asked my mother what was wrong? Looking forward to consulting your doctor help me.

Hello, Ms. Quy! She was born in 1959, so her mother must be over 80 years old. At this age, it is necessary to have a clinical examination because there are often many accompanying diseases such as blood pressure, blood fat, ischemic attack or dementia, .. There may be a coincidence that makes her mother forget a lot. job. She needs to take her mother to a hospital with a neurologist for examination and treatment as soon as possible.
