Question

Quizplus · Accepted Answer

Dementia brings a progressive, general deterioration of mental faculties, including deterioration of perceiving, thinking, and remembering. Cognitive functioning declines abnormally. Dementia, not a part of normal aging, represents a pathologic development. The irreversible brain damage may be the result of compromised blood flow to the brain resulting from atherosclerosis, thrombi, or trauma. In addition, toxins, metabolic conditions, organic disorders, infections, tumors, or Alzheimer's disease (AD) may be responsible for the deterioration (see Figure 13-19). The onset may be slow and insidious or may be sudden, depending on the cause.
