In her 70 s, she forgot where she put her things and said they stole them. What kind of disease is this?

Hello! In her 70 s, she forgot where she put her things and said they were stolen. This is senile amnesia or mild Alzheimer's disease. When people get old, all parts of the body will decline, especially memory. Most people will lose their memory, forget the east and the west, forget this and that, and sometimes they just pick up things and don't know what to do. Children and grandchildren are always joking, and sometimes they call their sons over. If they think it's wrong, they're also called grandchildren. When calling them, they are not called this grandson but that grandson, because the forgetfulness of old people often makes the family "restless." Families with elderly people need to understand and take care of them. I hope everyone will feel safe when they are old.
