Sleep Terrors

Medically reviewed · Ratel Health editorial team · Sunday, 16 August 2026

A non-REM sleep arousal disorder involving abrupt episodes of terror during sleep, often with a scream, intense fear, and no memory of the episode.

Overview

Sleep terrors, a type of non-REM sleep arousal disorder, involve recurrent episodes of abrupt terror arousal from sleep, usually beginning with a panicked scream, accompanied by intense fear and signs of autonomic arousal, with little or no memory of the episode afterward.

Signs and Symptoms

Symptoms can include sudden screaming, sweating, rapid heartbeat, and being difficult to console or wake, typically occurring during the first third of the night. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.

Causes and Risk Factors

Sleep terrors are more common in children and can be triggered by sleep deprivation, fever, or stress; family history is a notable risk factor.

Diagnosis

A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.

Treatment

Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.

Psychotherapy

Ensuring adequate, consistent sleep and reducing known triggers are the primary management strategies.

Living With Sleep Terrors

Remaining calm and ensuring safety during an episode, rather than attempting to fully wake the individual, is generally recommended.

When to Seek Professional Help

Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.

Outlook

Sleep terrors are common in childhood and typically resolve with age.
