Document Summary
Keyconcepts cognition is based on a system of interrelated abilities, such as perception, reasoning, judgment, intuition, and memory that allow one to be aware of oneself and one"s surroundings. Impairments in these abilities can result in a failure of the afflicted person to recognize that he or she is ill and in need of treatment. Neurocognitive disorders are characterized by a decline in cognitive function from a previous level of functioning. These disorders are acquired and have not been present since early life. Keyconcepts delirium is a disorder of acute cognitive impairment that is caused by a medical condition (e. g. , infection), substance abuse, or multiple etiologies. Keyconcepts dementia is characterized by chronic cognitive impairments and is differentiated by underlying cause, not by symptom patterns. Dementia can be further classified as cortical or subcortical to denote the location of the underlying pathology. Cortical dementia results from a disease process that globally afflicts the cortex.
