exploding head syndrome

Benign parasomnia characterized by loud noise hallucinations during sleep-wake transitions, often described as explosive sounds.

Full Definition

Exploding head syndrome is a benign parasomnia characterized by the sudden perception of loud noises, such as explosions, gunshots, or crashing sounds, during the transition between sleep and wakefulness. These auditory hallucinations are typically brief, painless, and occur most commonly during sleep onset. The condition is more prevalent in older adults and women, and episodes may be associated with stress, fatigue, or sleep deprivation. Despite its dramatic name, the syndrome is harmless and does not indicate any underlying brain pathology. Treatment is usually reassurance, stress management, and sleep hygiene improvement.

Usage

Usage note: Despite the dramatic name, emphasize the benign nature when discussing with patients.
