Dementia refers to a loss of cognitive function (cognition) due to changes in the brain caused by disease or trauma. The changes may occur gradually or quickly; and how they occur may determine whether dementia is reversible or irreversible.

Cognition is the act or process of thinking, perceiving, and learning. Cognitive functions that may be affected by dementia include the following:

  • Decision making, judgment
  • Memory
  • Spatial orientation
  • Thinking, reasoning
  • Verbal communication

Dementia also may result in behavioral and personality changes, depending on the area(s) of the brain affected.
