Frontotemporal dementia is the shrinking of the frontal and temporal anterior lobes of the brain, states WebMD. Symptoms may include impulsive or listless behavior, socially inappropriate behavior, and progressive loss of language functions. No treatment has been shown to slow the progression, but antidepressants and behavior modification may improve symptoms.
Individuals with frontotemporal dementia may display unusual behavior such as a lack of caring and a lack of inhibition, according to Healthwise as cited by WebMD. They may neglect personal hygiene and have difficulty understanding words and naming objects. Individuals may say rude things to others, expose themselves or make sexually explicit comments. They may be obsessed with repetitive routines or develop unusual food obsessions, such as eating the same kind of food or eating in the same restaurant repeatedly.
Aging is the main risk factor for all types of dementia, explains WebMD, but some diseases that cause dementia, such as early-onset Alzheimer's disease and some frontotemporal dementias, may run in families. Individuals who are male; have high blood pressure or high cholesterol; have atherosclerosis, which can lead to coronary artery disease; have had a heart attack or stroke; and those with diabetes are at greater risk for developing frontotemporal dementia.
