Pseudobulbar Affect in Survivors of Extreme Prematurity With Cerebellar Injury: Support for the Cerebellar Link in Pathologic Laughter and Crying

Pseudobulbar affect, that is, pathologic laughter and crying is being increasingly recognized in adults and is seen in association with a number of diseases like Parkinson disease, dementia, traumatic encephalopathy, and others, but has not previously been described in children with cerebral palsy. The condition pseudobulbar affect may be due to lesions in (or degeneration of) the cerebro-ponto-cerebellar pathways. Here we report 2 children with cerebral palsy who have structural cerebellar injury because of their being born extremely premature who have pathologic crying and probably laughter.
