PULLMAN, Wash.It sounds like a phrase from Urban Dictionary, or the title of an animated gif, but a Washington State University researcher says "exploding head syndrome" is an authentic and largely overlooked phenomenon that warrants a deeper look.
"It's a provocative and understudied phenomenon," said Brian Sharpless, a WSU assistant professor and director of the university psychology clinic, who recently reviewed the scientific literature on the disorder for the journal Sleep Medicine Reviews. "I've worked with some individuals who have it seven times a night, so it can lead to bad clinical consequences as well."
People with the syndrome typically perceive abrupt, loud noisesdoor slams, fireworks, gunshotsas they are going to sleep or waking up. While harmless, the episodes can be frightening.
"Some people start to become anxious when they go into their bedroom or when they try to go to sleep," said Sharpless. "Daytime sleepiness can be another problem for people."
Some patients report mild pain. Some hear an explosion in one ear, others in both ears, and yet others within their heads. Some also see what looks like lightning or bright flashes.
Researchers do not know how widespread the problem is, but Sharpless is fielding enough reports of people with the disorder that he thinks it is more widespread than presumed. Just this week, a story on the disorder in Britain's Daily Mail prompted several people with the syndrome to contact him.
The term "exploding head syndrome" dates to a 1988 article in Lancet but it was described clinically as "snapping of the brain" in 1920. Silas Weir Mitchell, an American physician, wrote in 1876 of two men who experienced explosive-sounding "sensory discharges."
While the syndrome is recognized in the International Classification of Sleep Disorders, studies using electroencephalogram recordings have only documented the disruptions in periods of relaxed but awake drowsiness.
