balint syndrome
Pronunciation: BAH-lint
A visuospatial disorder featuring simultanagnosia, optic ataxia, and ocular apraxia following bilateral parietal damage.
Full Definition
Balint syndrome is a rare neurological condition resulting from bilateral damage to the posterior parietal cortex, typically involving the superior parietal lobules. The syndrome comprises three key features: simultanagnosia (inability to perceive more than one object at a time), optic ataxia (inability to reach accurately toward objects under visual guidance), and ocular apraxia (difficulty directing eye movements voluntarily). Patients may have relatively preserved central vision but struggle with visual scene integration and spatially-guided behaviors.
Usage
Usage note: Capitalize when referring to the eponymous syndrome. Often seen in posterior cortical atrophy.
