| CHMP2B-related frontotemporal dementia : CHMP2B-related frontotemporal dementia is a progressive brain disorder that affects personality, behavior, and language. The symptoms of this disorder usually become noticeable in a person's fifties or sixties, and affected people survive about 3 to 21 years after the appearance of symptoms. Changes in personality and behavior are the most common early signs of CHMP2B-related frontotemporal dementia. These changes include inappropriate emotional responses, restlessness, loss of initiative, and neglect of personal hygiene. Affected individuals may overeat sweet foods or place non-food items into their mouths (hyperorality). Additionally, it may become difficult for affected individuals to interact with others in a socially appropriate manner. They increasingly require help with personal care and other activities of daily living. Many people with CHMP2B-related frontotemporal dementia develop progressive problems with speech and language (aphasia). They may have trouble speaking, although they can often understand others' speech and written text. Affected individuals may also have difficulty using numbers (dyscalculia). In the later stages of the disease, many completely lose the ability to communicate. Several years after signs and symptoms first appear, some people with CHMP2B-related frontotemporal dementia develop problems with movement. These movement abnormalities include rigidity, tremors, uncontrolled muscle tensing (dystonia), and involuntary muscle spasms (myoclonus). As the disease progresses, most affected individuals become unable to walk. | |
