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 disorder characterized by the inability to recognize or interpret sensory information despite having intact sensory organs and normal cognitive abilities. The condition results from damage to specific brain areas responsible for processing and interpreting sensory input. 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 settings, agnosia significantly impacts functional independence and requires specific compensatory strategies and sensory substitution techniques.
Usage
Usage note: Specify type (visual, auditory, tactile) when documenting; not to be confused with aphasia or apraxia.
