anosognosia
Pronunciation: ah-no-sog-NO-zee-ah
Lack of insight or awareness of one's own mental illness, commonly seen in psychotic disorders and severe mood episodes.
Full Definition
Anosognosia is a neuropsychological condition characterized by the patient's inability to recognize or acknowledge their mental illness or symptoms. This phenomenon is particularly common in schizophrenia, bipolar disorder during manic episodes, and severe depression with psychotic features. The condition stems from dysfunction in brain areas responsible for self-awareness and can significantly impact treatment compliance and therapeutic alliance. Unlike denial, anosognosia represents a genuine neurological inability to perceive one's illness rather than a psychological defense mechanism.
Usage
Usage note: Distinguish from psychological denial - anosognosia is neurologically based, not a conscious defense mechanism.
