ABSTRACT
Pusher behavior (PB) is a disorder of postural control affecting patients with encephalic lesions. This study has aimed to identify the brain substrates that are critical for the occurrence of PB, to analyze the influence of the midline shift (MS) and hemorrhagic stroke volume (HSV) on the severity and prognosis of the PB. We identified 31 pusher patients of a neurological unit, mean age 67.4±11.89, 61.3 percent male. Additional neurological and functional examinations were assessed. Neuroimaging workup included measurement of the MS, the HSV in patients with hemorrhagic stroke, the analysis of the vascular territory, etiology and side of the lesion. Lesions in the parietal region (p=0.041) and thalamus (p=0.001) were significantly more frequent in PB patients. Neither the MS nor the HSV were correlated with the PB severity or recovery time.
RESUMO
A síndrome do empurrador (SE) é um distúrbio de controle postural que acomete indivíduos com lesões encefálicas. Os objetivos deste estudo foram identificar as estruturas encefálicas envolvidas na SE, analisar a influência dos desvios de linha média (DLM) e volume do hematoma (VH) na gravidade e duração da SE. Dentre os pacientes internados na enfermaria de neurologia, foram identificados 31 pacientes com SE, idade média 67,4±11,89, 61,3 por cento homens. Foram realizados exames neurológico e funcional. As análises das neuroimagens incluíram medidas de VH em pacientes com doença cerebrovascular (DC) hemorrágica, DLM, análise do território vascular, etiologia e lado da lesão. Lesão nas regiões parietal (p=0,041) e talâmica (p=0,001) foram significativamente mais frequentes nos pacientes com SE. Não foi observada correlação dos DLM e volume do hematoma com a gravidade e duração da SE.
