Stress response with current danger

Suicidal intent, ongoing violence or abuse, severe dissociation, dangerous agitation, inability to care for self or dependants, acute intoxication or withdrawal, or physical injury requires immediate safety and medical care rather than watchful waiting.

Action: Establish whether threat is continuing, use ABCDE for injury or physiological disturbance, assess suicide and safeguarding, and mobilise emergency, crisis, social and practical support. Do not demand a detailed emotional account before urgent needs and consent are addressed.

Synopsis

Distinguish common early responses to trauma, clinically important acute stress syndromes and maladaptive responses to wider stressors, while prioritising safety, practical support, active monitoring and proportionate psychological care.

  • Distress, poor sleep, intrusive memories, irritability, startle, numbness and concentration difficulty are common soon after trauma and do not inevitably progress to PTSD.
  • DSM-5 acute stress disorder, the term used in NICE NG116, requires nine or more symptoms across intrusion, negative mood, dissociation, avoidance and arousal lasting from three days to one month after trauma; ICD-11 acute stress reaction is instead a transient normal-range response that usually begins to subside within days.
  • Adjustment disorder describes clinically important distress and impaired adaptation arising in relation to an identifiable psychosocial stressor when another mental disorder does not better explain the presentation.
  • Assess current danger, suicide, injury, substances, housing, dependants, culture, loss and practical needs before deciding that symptoms need a disorder-specific intervention.
  • Use active monitoring with follow-up within one month for subthreshold post-traumatic symptoms, but offer individual trauma-focused CBT within the first month to adults with acute stress disorder or clinically important PTSD symptoms.
  • Provide flexible practical help and listen without pressure; do not offer psychologically focused debriefing or compel everyone to recount the event in detail.
  • Do not use drug treatment, including benzodiazepines, to prevent PTSD; prescribe only for a separately assessed indication with its own benefit, risk and stop plan.

    • Key red flags

    Current violence, coercive control, trafficking, unsafe accommodation or contact with the perpetrator makes environmental protection an immediate clinical intervention.

    Suicidal planning, severe hopelessness, reckless behaviour or inability to meet basic needs requires urgent mental-health assessment rather than routine follow-up.

    Fluctuating attention, seizure, head injury, hypoxia, severe intoxication or withdrawal can mimic or complicate an acute stress reaction and needs medical assessment.

    Severe dissociation, wandering, inability to recognise surroundings or loss of caregiving capacity requires an immediate supported safety plan and specialist input.

    Investigation priorities

    01
    Stressor and trauma timelineFirst step

    Clarify exposure, onset, symptom evolution, previous adversity, losses and whether threat continues.

    Management branches

    Immediate supportRestore safety and practical control

    A person has recently experienced trauma, loss or a major stressor.

    1. Check physical needs, current danger, suicide and safeguarding and mobilise shelter, healthcare, information and trusted support as required.
    2. Listen at the person's pace, validate reactions without predicting illness and help re-establish sleep, meals, routine and manageable decisions.
    3. Provide a named contact and follow-up plan and advise against heavy alcohol, non-prescribed sedatives and repeated distressing media exposure.
