My mum was diagnosed with dementia in 2003 age 56 but scan showed she probably started 3 or 4 years previously. My mum was a single parent (i am 40) and i have no other family. My grandma had schizophrenia and then dementia (died 1997 age 82) I always knew my mum was 'different' to other peoples mums but people would say everyone thinks that but i found out last year that my mum was diagnosed with a schzoid personality in 1972 ( i remember going to see the psychiatrist with her because the nurses made me paper clothes for my doll) life was very difficult for me. When my mum was diagnosed the consultant said there was a high chance i will get it (dementia) too although they havent been able to diagnose cause of it. mum did not have damage in area of brain usual in Alzheimers (hippocampus) but responded very well to aricept which i understand she would not do if this was frontal dementia. She is now in late stages of disease. I have neither mental illness or personality problems and if there were anything to show that the dementia is related to either of these i must admit i would have more peace of mind (is this bad choice of words?!) Can anyone help?
