A woman named Bella Kilmartin, who is a pharmacy dispenser, said that she experience sudden attacks of sleep every time she laughs hard.
24-year-old was diagnosed with narcolepsy, a chronic sleep disorder characterized by overwhelming daytime drowsiness and sudden attacks of sleep.
She also has cataplexy, which causes sudden muscle weakness and is triggered by strong emotions.
“When the cataplexy initially started, the best way to describe it is I’d feel light-headed when I laughed. Then it progressed so that my eyes would flicker and my eyelids would go all droopy," she said.
Cataplexy is a sudden, brief loss of voluntary muscle tone triggered by strong emotions such as laughter, which is associated with sleep disorder narcolepsy.
Sodium oxybate is approved for the treatment of cataplexy.
