hemispatial neglect
Neurological condition characterized by failure to attend to or respond to stimuli presented on one side of space, typically the left side following right hemisphere damage.
Full Definition
Hemispatial neglect, commonly referred to as unilateral spatial neglect, is a complex neurological syndrome characterized by the inability to perceive, respond to, or orient toward stimuli presented in the contralesional side of space. Most commonly observed following right hemisphere stroke, particularly involving the parietal cortex, neglect typically affects the left side of space. The condition extends beyond simple sensory loss, involving deficits in spatial attention, awareness, and motor intention. Patients may ignore food on one side of their plate, fail to dress one side of their body, or omit details on one side when copying drawings. Assessment involves tasks such as line bisection, figure copying, and cancellation tests. Hemispatial neglect significantly impacts functional recovery and requires specialized rehabilitation approaches targeting spatial awareness and attention.
Usage
Usage note: Distinguish from visual field defects; specify assessment methods and severity when documenting.
