Dementia is the name given to a group of neurological disorders that progressively deteriorate the ability of the brain to function normally. In order to be diagnosed with dementia, there must be:
* A disturbance in memory
* A decline in two or more cognitive domains that is sufficient in severity to cause functional impairment. These cognitive domains include language, visuospatial function, executive function (foresight, planning, anticipation, insight, etc.), and praxis (learned motor skills).
