Frontotemporal dementia (FTD) encompasses a range of brain disorders that primarily impact the frontal and temporal lobes, which are crucial for regulating personality, behavior, and language.

The primary symptoms of frontotemporal dementia are marked by profound shifts in behavior and personality. These changes typically encompass:

• 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.
