Rare brain disorder that causes dementia is hereditary

New research shows that a rare brain disorder that causes early dementia is highly hereditary. The brain disorder, called frontotemporal dementia, is formerly known as Pick's disease and destroys parts of the brain, leading to dementia, including problems with language or changes in behavior and personality. The disease often affects people under the age of 65. The study is published in the November 3, 2009, issue of Neurology®, the medical journal of the American Academy of Neurology.
