Abstract:
Various brain areas in both cortical as well as subcortical locations are involved in pathological laughter. Pathological laughter may be seen as a prodromal symptom or acute manifestation or late sequel of stroke. Various other neuropsychiatric conditions attribute to stroke. It is often difficult to ascertain the cause of pathological laughter in the presence of multiple brain pathologies. Here, we highlight a case of a 55-year-old female, who had multiple episodes of stroke and subdural hematoma, presented with pathological laughter and other behavioral abnormalities.
