hemi-neglect
The failure to attend to or respond to stimuli in one half of space, typically following brain injury.
Full Definition
Hemi-neglect, also known as spatial neglect or unilateral neglect, is a neuropsychological condition characterized by the failure to attend to, perceive, or respond to meaningful stimuli presented on one side of space, typically the left side following right hemisphere damage. This condition extends beyond simple sensory loss and represents a complex disorder of spatial attention and awareness. Hemi-neglect can significantly impact rehabilitation outcomes and daily functioning, affecting reading, navigation, and self-care activities.
Usage
Usage note: Specify side affected and document specific behavioral examples; distinguish from sensory deficits.
