What is Frontotemporal Dementia?

By Elizabeth Stannard Gromisch HERWriter

About 2 to 10 percent of dementia cases are frontotemporal dementia, a group of diseases in which nerve cell degeneration occurs in the frontal and temporal lobes of the brain, according to the National Institute of Neurological Disorders and Stroke. The majority of patients begin having symptoms between the ages of 40 and 65.

Several disorders fall under the grouping of frontotemporal dementia. These include semantic dementia, Pick’s disease and primary progressive aphasia.

The symptoms of frontotemporal dementia fall into two main categories: behavior changes and language difficulties.

For example, with behavioral changes, the patient may have a decline in her personal hygiene, participate in more inappropriate actions, including socially inappropriate behaviors, and experience a loss of empathy. She may also overeat and have a lack of judgment.

Other behavioral symptoms of frontotemporal dementia include repetitive compulsive behavior, apathy, and a lack of awareness of these changes. The language problems of frontotemporal dementia depend on the type the patient has.

With primary progressive aphasia, for example, the patient has difficulty with written and spoken language, both understanding it and using it. But with semantic dementia, the patient speech is grammatically correct, but the content of her speech does not pertain to the conversation she is having.

Some patients may have trouble with movement, such as muscle weakness, tremors and poor coordination. The Family Caregiver Alliance noted that in the late stage of frontotemporal dementia, patient may progress to mutism, have a loss of muscle movement, or not make motor responses when given a verbal command. Patients may also experience memory loss later in the disease.

The National Institute of Neurological Disorders and Stroke noted that the prognosis of frontotemporal dementia is poor, with some patients requiring 24-hour care at either their home or an inpatient setting.

On average, patients live with frontotemporal dementia for five to 10 years after they are diagnosed.
