Frontotemporal dementia is a progressive condition, which tends to affect younger people, usually aged 45 to 65 years, but can be younger, and can be difficult to diagnose.
The region of the brain most affected is the frontal lobes. Frontotemporal dementia affects behaviour and personality, and this can cause dis-inhibition and inappropriate social behaviour. Eating patterns can also be affected, with people suddenly bingeing on food, especially sweet foods.
It is possible to have not just one but two types of dementia.
The most common is a combination of Alzheimer’s disease and vascular dementia, known as mixed dementia.
A person with mixed dementia would experience a mixture of the symptoms associated with the types of dementia they have.
