anosognosia
Pronunciation: an-oh-sog-NOH-zee-ah
A neuropsychological condition where patients lack insight into or deny their mental illness or disability.
Full Definition
Anosognosia is a neuropsychological phenomenon characterized by a patient's inability to recognize or acknowledge their mental illness, cognitive deficits, or functional impairments. This condition is particularly common in severe mental illnesses such as schizophrenia and bipolar disorder, where patients may deny symptoms despite clear evidence of dysfunction. The term derives from Greek meaning 'without knowledge of disease' and represents a significant clinical challenge as it often leads to treatment non-compliance. In psychiatric contexts, anosognosia is distinguished from simple denial or psychological defense mechanisms, as it appears to have neurobiological underpinnings related to brain dysfunction in areas responsible for self-awareness and insight.
