anosognosia
Pronunciation: an-oh-sog-NOH-zee-ah
Lack of insight or awareness of one's own cognitive deficits or functional impairments, particularly common in dementia patients.
Full Definition
Anosognosia is a neuropsychiatric condition characterized by the patient's unawareness or denial of their own illness or disability. In geriatric psychiatry, it is frequently observed in patients with Alzheimer's disease and other dementias, where individuals may adamantly deny having memory problems despite clear evidence of cognitive decline. This phenomenon results from damage to brain regions responsible for self-awareness and insight. Anosognosia significantly complicates treatment adherence and safety planning, as patients may resist care interventions or engage in risky behaviors. Clinical assessment involves structured interviews and informant reports to document the discrepancy between actual deficits and patient awareness.
Usage
