Agnosia
Pronunciation: ag-NO-see-ah
Inability to recognize or interpret sensory information despite intact sensory organs and cognitive function.
Full Definition
Agnosia is a neurological condition characterized by the inability to recognize or interpret sensory information despite normal sensory organ function and adequate cognitive abilities. Common types include visual agnosia (inability to recognize objects by sight), auditory agnosia (inability to recognize sounds), and tactile agnosia (inability to recognize objects by touch). In rehabilitation medicine, agnosia commonly occurs following stroke, traumatic brain injury, or other brain lesions affecting specific cortical areas. The condition significantly impacts functional independence and safety, requiring specialized occupational therapy interventions to develop compensatory strategies and environmental modifications.
Usage
Usage note: Specify type of agnosia when known; distinguish from sensory impairments or general cognitive deficits.
