In the first days and weeks, practical help is mental-health help: safety, medicine, sleep, food, transport, accurate information, and contact with people you trust. The VA’s National Center for PTSD says most people with mild or moderate distress do not need formal treatment immediately.
Psychological First Aid is an evidence-informed support model, not proof that one early intervention prevents PTSD. Current VA guidance says evidence is insufficient for therapy or medication given automatically to everyone exposed to trauma—and specifically does not recommend compulsory critical-incident debriefing.
Assessment becomes more useful when reactions keep intensifying, do not begin to ease, or interfere with sleeping, parenting, school, work, medication, driving, or basic decisions. Persistent PTSD can be treated with trauma-focused therapies; the first week is not a deadline to diagnose yourself.
