Quizplus · Accepted Answer

Dementia is characterized by the general loss or ineffectiveness of brain cells, leading to a decline in cognitive function. This loss of brain cells is often caused by certain diseases, such as Parkinson's or Alzheimer's, that affect the brain's structure and function. Spinal cord injury, dysfunction of the reticular activating system of the midbrain, dysfunction of the hindbrain, or damage to the cerebellum are not typically associated with dementia.
