11-Loss of memory
Sometimes it is difficult for the person to remember events from the recent or remote past, because of the reduced oxygen flow that reaches the brain. They may forget things as simple as the location of the house’s keys, the different rooms of the home, and even the name of their relatives. However, do not be alarmed every time you forget something. It is normal not to remember things, especially at an advanced age. However, the danger is when the change is sudden, and there is no history of neurodegenerative diseases, such as Alzheimer’s.
