anosgnosia
Pronunciation: an-oh-sog-NOH-see-ah
A neurological condition where patients lack awareness or deny their own cognitive or physical deficits.
Full Definition
Anosgnosia is a neurological phenomenon characterized by a patient's inability to recognize or acknowledge their own cognitive, sensory, or motor impairments. This condition is commonly observed in stroke patients, particularly those with right hemisphere lesions, and in individuals with dementia. From an editorial perspective, it's crucial to distinguish this from simple denial or psychological defense mechanisms, as anosgnosia represents an actual neurological inability to perceive deficits. The term should not be confused with insight impairment, which may be partial rather than complete.
Usage
Usage note: Always italicize when first introduced in clinical documentation. Avoid using as synonym for simple denial.
