anosognosia
Pronunciation: an-oh-sog-NO-zee-uh
A neurological condition where patients lack awareness or deny their neurological deficits following brain injury.
Full Definition
Anosognosia is a complex neuropsychological phenomenon characterized by a patient's lack of awareness or explicit denial of their neurological impairments following brain injury, most commonly after right hemisphere stroke. Patients may deny obvious deficits such as hemiplegia, claiming they can move paralyzed limbs or attributing movement failures to external factors. This condition significantly complicates rehabilitation efforts as patients may not understand the need for therapy or safety precautions. Anosognosia can be domain-specific, affecting awareness of motor, visual, or cognitive deficits differently. Assessment involves structured interviews and behavioral observations, while treatment approaches focus on gentle confrontation techniques and experiential learning.
Usage
Usage note: From Greek meaning 'without knowledge of disease'; distinguish from simple denial or poor insight.
