A síndrome de Balint é uma doença neurológica rara caracterizada pela tríade de ataxia óptica, apraxia ocular e simultanagnosia devido a lesões do lobo parietal posterior. Os pacientes relatam dificuldades oftalmológicas na ausência de anomalias oftalomológicas subjacentes e apresentam graves deficiências visuais e espaciais para localizar e alcançar objetos, iniciar movimentos oculares voluntários e perceber mais de um objeto por vez.
Introdução
O que você precisa saber de cara
A síndrome de Balint é uma condição neurológica rara que surge após lesões no lobo parietal posterior do cérebro. Ela provoca graves dificuldades para alcançar objetos no espaço, direcionar o olhar de forma voluntária e conseguir enxergar mais de um elemento de cada vez. A família e a pessoa costumam notar falhas visuais importantes, embora os olhos estejam perfeitamente saudáveis em exames oftalmológicos. Não há medicamentos específicos dispensados para a condição, e a doença não consta na lista oficial de PCDTs de doenças raras do Ministério da Saúde.

Between the Borders: Balint Syndrome as a Rare Manifestation of Posterior Circulation Stroke.
Balint syndrome is a rare disorder caused by bilateral parieto-occipital damage, most often occurring within the posterior watershed territory between the middle and posterior cerebral arteries. It is characterized by a triad of simultanagnosia, optic ataxia, and oculomotor apraxia, and is often misdiagnosed as delirium, dementia, or cortical blindness, particularly in elderly patients. We report a case of an 82-year-old woman who presented with confusion and visuospatial disorientation following a collapse. Her visual acuity was preserved, but she demonstrated simultanagnosia and oculomotor apraxia. Computed tomography of the brain revealed bilateral occipital watershed infarcts, consistent with Balint syndrome secondary to posterior border-zone infarction. She was managed with secondary stroke prevention and commenced on neurorehabilitation focusing on visuospatial and visuomotor retraining. This case highlights the importance of recognizing Balint syndrome as a rare manifestation of posterior circulation stroke. Awareness of its classic triad facilitates early diagnosis, appropriate neuroimaging correlation, and tailored rehabilitation to optimize patient outcomes.
Bálint Syndrome From Posterior Cerebral Artery Infarctions Case Report.
Bálint syndrome is a debilitating, rare neurological condition characterized by a triad of visuospatial distortions: simultanagnosia, optic ataxia, and oculomotor apraxia. We highlight the pathways involved with infarction of the posterior cerebral artery (PCA), which may be an important underlying factor leading to the development of clinical presentations found in Bálint syndrome. We present a case of a middle-aged patient who presents with Bálint syndrome following a PCA infarction. A 49-year-old male bus driver with a recent PCA infarction presented with all 3 components of Bálint syndrome. His clinical course was notable for simultanagnosia, optic ataxia, oculomotor apraxia, and a right greater than left lower visual field deficit. Neuroimaging revealed infarctions in the P1 and bilateral P2 segments of the posterior cerebral arteries, affecting the parieto-occipital regions known to underlie visuospatial processing. Laboratory workup helped exclude opportunistic and systemic causes, supporting a stroke-related etiology. Posterior cerebral artery infarctions may be responsible for the clinical presentation of Bálint syndrome; however, further investigation into vascular and neuronal networks underlying the clinical signs and symptoms of Bálint syndrome is needed.
Balint Syndrome in a Patient With Isolated Corpus Callosum Stroke: A Case Study With Narrative Review.
We report a case of an isolated bilateral corpus callosum stroke (body and splenium) who exhibited Balint syndrome (optic ataxia, simultanagnosia, optic apraxia), along with a partial Gerstmann syndrome (left/right disorientation, acalculia, finger agnosia), with extinction to double simultaneous stimulation and astereognosis without direct involvements of the parietal lobes. We review the vascular anatomy of the corpus callosum, mechanisms and risk factors for stroke in this area, and the components of Balint syndrome and localization, with descriptions of recent data on neural networks involved in higher-level cortical function. Attention to the visual-spatial symptoms of Balint syndrome is important to consider when evaluating and treating patients with ischemic disease of the corpus callosum.
