Gelastic seizures are a sudden outburst of laughter, or, if it’s crying they’re known as dacrystic. Gelastic originates from ‘Gelastikos’ which is the Greek word meaning laughter.
These seizures are predominantly found in children prior to the age of 4 and statistics show that a greater number of boys than girls suffer with them. It has been documented that some older children do experience an aura before the seizure occurs and it’s duration is about 30 to 45 seconds.
I shan’t launch into all the details as I discovered this wonderfully heart warming story broadcasted on ABC News which is filled with information.
