IncontinĂȘncia do choro e infarto protuberancial unilateral Incontinence of crying and unilateral pontine infarct
O presente estudo trata do caso de um paciente que apresentou incontinĂȘncia do choro e hemiplegia direita por infarto ventroprotuberancial paramediano detectado pela RNM. O carĂĄter circunscrito da lesĂŁo foi endossado pela normalidade dos potenciais evocados sĂŽmato-sensitivos e auditivos de curta-latĂȘncia. Os episĂłdios de choro desapareceram poucos dias depois do inĂcio do tratamento com doses baixas de imipramina. Discutimos o choro e riso patolĂłgicos como forma de incontinĂȘncia da mĂmica resultante de desconexĂŁo lĂmbico-motora, enfatizando a impropriedade de incluĂ-los na sĂndrome pseudobulbar, uma vez que dependem de correlatos anatĂŽmicos e funcionais distintos.<br>A 64-year-old man presented with pathologic crying and right hemiplegia due to a unilateral pontine infarct from probable branch disease of the basilar artery. The circumscribed nature of the lesion was supported by MRI and short-latency evoked potentials. The weeping spells ceased after a few days of imipramine in low doses. Pathologic laughing and crying can be viewed as a limbic-motor disconnection syndrome, in which the faciovocal motor system is released from forebrain afferents carrying information of emotional content. The inclusion of pathologic laughing and crying in the syndrome pseudobulbar palsy is inaccurate and misleading, since each is related to distinct functional and anatomic systems intrinsic to the human brainstem
