How long has your loved one had dementia or Alz D. I think my mother has had ti since 1972 when she started acting strange. She was only in her 40's then. My husband also has dementia. His symptoms started about 1978 when he was also in his 40's. They were both subtle symptoms but very strange and odd things to say and do. So its been a fun time the last 40 years, not. I had to seek psychological help. Its a wonder I didn't start drinking. I must be a strong lady and don't know it.
