Frontotemporal Dementia: Symptoms & Signs

Fronotemporal dementia is a condition characterized by shrinking and decreased function of the frontal and temporal lobes of the brain. It is believed to be a group of different diseases that share the degeneration of nerve cells in these areas of the brain. Examples of frontotemporal dementia include Pick's disease and semantic dementia.

Signs and symptoms associated with frontotemporal dementia fall into one of two categories: changes in behavior or problems with language. Symptoms and signs include

  • loss of empathy,
  • poor judgment,
  • socially inappropriate behavior,
  • lack of inhibition,
  • repetitive compulsive behavior,
  • inability to concentrate or plan,
  • speech difficulties,
  • memory loss,
  • neglect of personal hygiene,
  • agitation, and
  • blunted emotions.

Symptoms typically progress steadily and often rapidly.
