摘要:
Balint's syndrome is a rare visuospatial disorder usually associated with bilateral and rarely unilateral parieto-occipital or just parietal lobe lesion and sometimes temporal lobe. It is characterized by triad of spatial disorder of attention/simultanagnosia, psychic paralysis of gaze/oculomotor apraxia, and optic ataxia. The most common etiologies for developing this syndrome are stroke, Alzheimer's disease, and brain trauma. A 70-year-old hypertensive male patient complained of difficulty in executing his day-to-day work. He gave history of sudden onset left-sided weakness of his body 8 months back which resolved in a period of 1 month. He complained some visual disturbances later on which he ignored. On examination, he had all the three features of Balint's syndrome as noted above. His plain computed tomography brain and skull revealed infarct in the right parieto-occipital region, lacunar infarcts in capsule-ganglionic region and multiple site of senile cortical atrophy. Radiological findings along with clinical findings and history mentioned above, the patient was diagnosed to have Balint's syndrome as a complication of brain injury in parieto-occipital area by stroke.
