My mother is a 79-year-old female who, until this month, has been extremely active for her age. She gardens and cans and keeps house for my father. Recently she started having a roaring in her ears, dizziness, temporary trouble seeing and hearing, and mild forgetfulness. Then tonight she totally forgot that her brother had died two years ago and had to undergo all the emotional grief all over again. It finally came back to her that he had passed away, but this was very upsetting for the whole family.
