The neurologist said his laughter was actually seizures

A Hyderabad neurologist described a troubling case of a three-year-old who laughed frequently for a year, leading parents to believe he was simply happy. MRI later uncovered hypothalamic hamartoma, a rare condition that triggers gelastic seizures often mistaken for joy. Doctors now urge caregivers to get medical evaluation for repeated, unprovoked laughter to enable early diagnosis and care.
