night terrors
Night terrors are episodes of intense fear during sleep that involve screaming, physical movement, and autonomic arousal (racing heart, rapid breathing, sweating). Unlike nightmares, they occur during non-REM sleep with no memory of the event afterwards.
Night terrors affect both children and adults, with higher prevalence in neurodivergent populations, particularly those with ADHD.
They're triggered by sleep disruption, stress, hormonal changes, and sometimes medication, reflecting both neurological and environmental factors.
