Behavioral changes

The most common symptoms of frontotemporal dementia involve extreme changes in behavior and personality. These include:

Increasingly inappropriate social behavior.
Loss of empathy and other interpersonal skills. For example, not being sensitive to another person's feelings.
Lack of judgment.
Loss of inhibition.
Lack of interest, also known as apathy. Apathy can be mistaken for depression.
Compulsive behaviors such as tapping, clapping, or smacking lips over and over.
A decline in personal hygiene.
Changes in eating habits. People with FTD typically overeat or prefer to eat sweets and carbohydrates.
Eating objects.
Compulsively wanting to put things in the mouth.
