Frontotemporal dementia. The diagnosis of<unk>  can be divided into the following three categories: * Clinical history<unk> s may be recognized through a sudden and dramatic change in a person's personality, for example with loss of social awareness, disinhibition, emotional instability, irritability or impulsiveness. Alternatively, the disorder may become apparent because of mood changes such as depression, anxiety or apathy. * Examination On mental state examination a person with<unk> <unk>  damage may show speech problems, with reduced verbal fluency. Typically the person is lacking in insight and judgment, but does not have marked cognitive abnormalities or memory impairment (as measured for example by the mini-mental state examination). With more severe impairment there may be echolalia or mutism. Neurological examination may show primitive reflexes (also known as<unk>  release signs) such as the grasp reflex. Akinesia (lack of spontaneous movement) will be present in more severe and advanced cases. * Further investigation A range of neuropsychological tests are available for clarifying the nature and extent of<unk> <unk>  dysfunction. For example, concept formation and ability to shift mental sets can be measured with the Wisconsin Card Sorting Test, planning can be assessed with the Mazes subtest of the WISC. Frontotemporal dementia shows up as atrophy of the<unk>  cortex on MRI.<unk>  impairment due to head injuries, tumours or cerebrovascular disease will also appear on brain imaging.
