I was 31 when my mum started MI dementia. My son was 6. It was hard. Though time i learned to try and have a normal life when i was away from it ( but that wasn't a lot of times) My son was 20 when his Dad got it as well. He finds it hard to see him now. There is so much needs to be done for this now. My husband has deteriorated rapidly whist my mum was 13years with it.Both different mum taking strokes and my husband taking seizures. Its a cruel illness not just for the sufferer but the family suffer as well.
