Frontotemporal dementia: Introduction
Frontotemporal dementia includes a variety of types of dementia, seriously disabling neurodegenerative diseases of the brain that cause a progressive and permanent loss of cognitive and mental performance. Frontotemporal dementia causes shrinkage degeneration of the nerve cells of temporal and frontal lobes or areas of the brain. These areas of the brain are important to decision-making, language, emotion, personality, and behavior control.
Frontotemporal dementia is less common than some other types of dementia, such as Alzheimer's disease and vascular dementia. One type of frontotemporal dementia is called Pick's disease. Some forms of frontotemporal dementia are the result of hereditary conditions, but there is no known cause of frontotemporal dementia in some forms of the disease.
Symptoms of frontotemporal dementia generally begin in the fourth through sixth decade of life and are progressive. The rate of development of symptoms varies between individuals. The types of symptoms vary as well depending on the specific area of the brain that is affected. Symptoms can affect personality, behavior, language, memory, emotion and may also affect muscles. For more details on symptoms and complications, refer to symptoms of frontotemporal dementia.
There is no specific diagnostic test that can detect frontotemporal dementia. Making a diagnosis is based on symptoms and includes performing a variety of tests and assessments that evaluate the brain and can rule out other causes of symptoms, such as vascular dementia and psychiatric disorders. Diagnosis and treatment may require the collaboration of a variety of providers, including a primary care physician, neurologist, psychiatrist, and/or psychologist.
The diagnostic process begins with taking a thorough personal and family history, including symptoms, and completing a physical examination. This includes a neurological exam. A neurological exam evaluates the nerves and nervous system and such functions as alertness, orientation, reflexes, sensation, movement, balance, coordination, vision, and hearing.
Commonly used tests include a mini-mental state examination (MMSE), which evaluates mental function by assessing the answers provided to a series of questions. Imaging tests that are used in the diagnostic process include CT and MRI, which provide information about the structure of the brain. However, these tests may not be able to detect changes in the brain of frontotemporal dementia until late stages. A PET scan may be performed in some cases. A PET scan is an imaging test that can show how well different areas of the brain are functioning. An EEG (electroencephalogram) may be performed to measure and record the electrical activity of the brain through sensors that are painlessly attached to the scalp. An EEG can detect abnormal patterns of electrical activity that may be present in dementia.
It is possible that a diagnosis of frontotemporal dementia can be missed or delayed because symptoms may develop gradually and are similar to symptoms of other diseases and conditions. For more information about diseases and conditions that can mimic frontotemporal dementia, refer to misdiagnosis of frontotemporal dementia.
Frontotemporal dementia is not curable, and at this time there are no treatments that can slow the advancement of the disease. However, there are some medications and therapies that may help to reduce some symptoms and maximize independence and the quality of life. There are also clinical trials taking place to research potential treatments. For more information on treatment, refer to treatment of frontotemporal dementia. ...more »

Frontotemporal dementia: Misdiagnosis
A diagnosis of frontotemporal dementia may be delayed or missed because early symptoms may develop gradually and or may be associated with the normal aging process. In addition, symptoms of frontotemporal dementia can mimic symptoms of a variety of diseases, disorders or conditions. These include psychosis, obsessive compulsive disorder, Alzheimer's disease, TIA, depression, ...more misdiagnosis »
