- Exploding head syndrome.

Exploding head syndrome

 

Def:- is a condition that causes the sufferer occasionally to experience a tremendously loud noise as originating from within his or her own head, usually described as the sound of an explosion, roar, gunshot, loud voices or screams, a ringing noise, or the sound of electrical arcing (buzzing).
This noise usually occurs within an hour or two of falling asleep, but is not necessarily the result of a dream and can happen while awake as well.

Causes:- 
The cause of the exploding head syndrome (EHS) is not known, but :

• Some physicians have reported its correlation with stress, anxiety, and extreme fatigue.
• It may be the result of a sudden movement of a middle ear component or of the eustachian tube. 
• It may be the result of a form of minor seizure in the temporal lobe where the nerve cells for hearing are located.
