Dementia represents a group of disorders characterized by memory dysfunction. There is a loss of cognitive
functioning (Latin: cognoscere, “to know, to conceptualize, or to recognize.”) that is the consequence of a variety of diseases and medical conditions affecting the human brain.
Dementia results in a loss of functioning in memory and one or more additional cognitive
deficits (Snyder, Nussbaum & Robins, 2006). Deficits in additional cognitive
domains include those of attention, thinking, producing and understanding language, judgment, problem-solving, and behavior. Neuropsychological symptoms such as apathy, agitation, and depression are also common in the dementias. These will be discussed later.
Memory impairment is often noticed early. However, other cognitive
problems such as disinhibition, self-control, and self-regulation seen in executive dysfunction may also present early.
