disease has feature Oculomotor apraxia simultanagnosia nervous system disorder Balint syndrome https://www.malacards.org/card/balint_syndrome Recent research in nonhuman primates (NHPs) suggests that many aspects of Balint's syndrome and optic ataxia are a result of damage to specific functional modules for reaching, saccades, grasp, attention, and state estimation. The deficits from large lesions in humans are probably composite effects from damage to combinations of these functional modules. Interactions between these modules, either within posterior parietal cortex or downstream within frontal cortex, may account for more complex behaviors such as hand-eye coordination and reach-to-grasp. UMLS:C4707368 psychic paralysis of visual fixation Orphanet:363746 GARD:0021558 Balint syndrome is a rare neurologic disease characterized by the triad of optic ataxia, ocular apraxia and simultanagnosia due to posterior parietal lobe lesions. Patients report ophthalmologic difficulties in the absence of underlying ophthalomologic anomalies and present severe visual and spatial disabilities in locating and reaching objects, initiating voluntary eye movements and perceiving more than one object at a time. icd11.foundation:491228434 MONDO:0018211 SCTID:765212008 MEDGEN:1646315 Balint-Holmes syndrome optic ataxia-gaze apraxia-simultanagnosia syndrome
