"His personality change…it was subtle. If we'd gone to a GP, they wouldn't have believed it."​

Mark Preston was diagnosed with Frontotemporal dementia at the age of 42. His wife, Caroline, has shared their story with the Alzheimer's Society.

Frontotemporal dementia is a less common cause of dementia in which the first noticeable symptoms can often be personality or behaviour changes rather than changes in memory.

You can read the blog post about their experiences here or watch the YouTube video here.

Hi, this is similar to my story. My husband was also diagnosed with Frontal Temporal Dementia. I was in my early 40s and he was mid 50s.
My John is now in a care home 6 years down the line. I tried for a long time to keep him at home with me because his memory of me didn't and hasn't changed at all. We did as much as possible in the first few years to ensure we didn't waste a moment.
Being so young he is 30 years younger than the oldest other resident and that is probably the strangest thing but he gets on with most other residents and enjoys the social that the care home has given him. At home we eventually became quite isolated and restricted in what we could do. Now he always has company and carers that are always available, knowledgeable and what feels like family members and I also have a network of carers and family relatives of other residents who understand around me too.
Everybody's story is unique but sharing definitely helps.
