Acute Stress Disorder Treatment in Texas
Acute stress disorder is an intense trauma reaction in the first month after a traumatic event — intrusive memories, nightmares, feeling numb or on edge, and avoiding reminders. It’s an early signal, and trauma-focused therapy now can ease the distress and lower the risk of PTSD later.

What is acute stress disorder?
Acute stress disorder (ASD) is an intense stress reaction in the days to weeks after experiencing or witnessing trauma. By definition it occurs within the first month. Distress after trauma is a normal human response — ASD is when that reaction is strong enough to significantly interfere with daily life.
Common symptoms
- Intrusive memories, nightmares, or flashbacks
- Feeling detached, numb, or in a daze
- Avoiding reminders of what happened
- Trouble sleeping, irritability, or feeling on edge
- Difficulty concentrating and heightened startle
How it differs from PTSD
The main difference is timing. Acute stress disorder describes the reaction in the first month; when trauma-related symptoms persist beyond about four weeks, the picture may meet criteria for post-traumatic stress disorder (PTSD). Treating ASD early can lower the risk of developing chronic PTSD.
How it’s treated
The treatment of choice is trauma-focused cognitive behavioral therapy (CBT) — education about trauma reactions, cognitive work, and gradual exposure to break patterns of fear and avoidance, plus stress-management skills. Starting trauma-focused CBT within the first few months has good evidence for reducing the risk of chronic PTSD. Medication isn’t first-line, but a prescriber may help with specific symptoms like sleep or anxiety.

Is it normal to feel this way after something traumatic?
Distress after trauma is a normal human response, and many people recover on their own. Acute stress disorder is when the reaction is intense enough to significantly interfere with daily functioning. Getting support doesn't mean you're weak — it can genuinely speed recovery and protect against longer-term difficulty.

When should I reach out?
If, after a traumatic event, symptoms are intense, aren't easing, or are getting in the way of daily life, it's worth reaching out — sooner rather than later. If you're having thoughts of suicide or feel unsafe, call or text 988 now, or call 911 in an emergency.
