Sometimes laughter requires its own medicine: according to CBS, 2 ½-year-old Matthew Ephrem suffers from a rare seizure condition which left him spastically laughing uncontrollably multiple times a day. “It’s heartbreaking. I mean heartbreaking to find out your child has a tumor,” said Tigist Feyisa, Matthew’s mother. But doctors think they may have been able to help him.

Matthew's brain lesion creating the laughing fits is called hypothalamic hamartoma—and Matthew recently had two extremely risky operations to remove nerve masses through the top of his head. And doctors say his spasms have stopped happening. “There is no word to explain how happy we are with result. Since he had the surgery almost 10 days…no seizure, no laughing, and he is becoming himself,” said father Ephrem Mekonnen.
