Behavioural-variant FTD

In the frontal or behavioural variant of frontotemporal dementia, the person’s mood and behaviour may become fixed and difficult to change, making individuals appear selfish and unfeeling. A loss of empathy and emotional warmth is very common. In contrast to Alzheimer’s disease, recent memory is typically preserved.

Apathy or lack of motivation is very common, leading people with FTD to abandon hobbies and avoid social contact. Others lose normal inhibitions and start talking to strangers or exhibiting embarrassing behaviour in public.

Difficulty in reasoning, judgement, organisation and planning is frequent, along with a reduction in spontaneous conversation. Changes in eating patterns are very common often with a craving for sweet food, a tendency to overeat and a restriction in food preferences.

A decline in self-care and a reduction in the ability to perform activities of daily living is another early feature. As the disease progresses, the person may become ‘obsessional’, repeating patterns of movement and behaviours like handwringing or echoing back whatever is said.
