Uncontrollable laughter caused by brain tumor

Uncontrollable fits of laughter, which was first diagnosed as misbehavior in a 6-year-old Bolivia girl, was later found out to be caused by a brain tumor, according to a report published in the journal ecancermedicalscience.

The laughing fits are actually gelastic seizures, a form of epilepsy that is relatively rare. After the girl underwent a brain scan, doctors found a hamartoma, a small, benign tumor, pressing into her brain’s temporal lobe. Surgeons removed the tumor, and the girl is now healthy and has ceased experiencing the laughing seizures.

Gelastic seizures can be scary for children, and they can also cause bouts of crying. These seizures are most often caused by tumors in the hypothalamus, particularly in children. If the tumor affects the pituitary gland, it can cause growth abnormalities.
