Two things about PTSD are worth knowing before anything else, and both cut against the intuition.
Most people who experience a traumatic event do not develop PTSD. Distress afterwards is close to universal; the disorder is not. Natural recovery over weeks is the normal course.
And the intervention that was for years routinely offered to people straight after a trauma — a single debriefing session — does not prevent PTSD, and in at least one trial was associated with more of it. That finding is the clearest example of why the guidelines here are worth reading rather than guessing.
What PTSD actually is
It is not simply "being badly affected by something terrible." The diagnosis has a specific structure, and knowing it helps both with recognising it and with not over-applying the label.
It begins with exposure to actual or threatened death, serious injury or sexual violence — and the routes to that exposure are broader than people assume. Directly experiencing it. Witnessing it. Learning that it happened to a close family member or friend. And repeated or extreme exposure to aversive details in the course of work, which is the route that covers first responders, emergency medicine, police, coroners' staff and content moderators.
Then four symptom clusters, all of which have to be present, persisting more than a month, and causing real distress or impairment:
1. Intrusion. Unwanted memories that arrive without being summoned. Nightmares. Flashbacks, which are not simply vivid recall but an experience of the event happening again now. Intense distress and physical reactions at reminders.
2. Avoidance. Effortful avoidance of memories, thoughts and feelings connected to the event, and of the external things that trigger them — places, people, conversations, whole categories of activity. This is the cluster that quietly shrinks a life.
3. Negative changes in thinking and mood. Persistent negative beliefs about yourself or the world, distorted blame, inability to feel positive emotion, detachment from people, loss of interest, and sometimes inability to remember parts of the event.
4. Changes in arousal and reactivity. Irritability or anger, reckless or self-destructive behaviour, hypervigilance, exaggerated startle response, difficulty concentrating, and disturbed sleep.
Under a month, with similar symptoms, the diagnosis is acute stress disorder rather than PTSD — which is a meaningful distinction, because most acute stress reactions settle without becoming PTSD.
Two things people often recognise themselves in
Delayed onset is real. Symptoms can emerge months or occasionally years after the event, sometimes triggered by something apparently unrelated. Having coped at the time does not rule this out, and a late presentation is not evidence that the problem is something else.
Complex PTSD is recognised in the ICD-11 classification: PTSD plus persistent difficulties with emotional regulation, a deeply negative self-concept, and difficulty sustaining relationships. It's typically associated with prolonged or repeated trauma, often interpersonal and often beginning in childhood. It is not "worse PTSD" — the additional features are the point, and they shape treatment.
The debriefing finding, in full
For years it was standard practice to bring people together shortly after a disaster, accident or assault for a single structured session in which they described what happened and how they felt. It was often compulsory. The reasoning was obvious and humane.
A Cochrane review examined the trials. Across 15 randomised trials, single-session individual debriefing did not prevent PTSD and did not reduce psychological distress compared with control. Worse, one trial found a significantly increased risk of PTSD at one-year follow-up in the group that received debriefing, with an odds ratio of 2.51.
The reviewers' conclusion was blunt: there is no evidence to support the practice, and compulsory debriefing of trauma victims should cease. They recommended a "screen and treat" approach instead — watch, identify the people who aren't recovering naturally, and treat those people properly.
It is worth sitting with why that might be. Most people recover on their own. An intervention delivered to everyone immediately may interrupt that process, or consolidate a memory at precisely the wrong moment, or communicate to someone who was coping that they shouldn't be.
What this does not mean is that you leave people alone after a trauma. Practical help, safety, information, and access to someone if things don't improve are all reasonable. What the evidence argues against is a mandatory, structured, one-off emotional debrief for everybody.
What actually works
The 2023 VA/DoD clinical practice guideline is unusually clear here, and its central recommendation is the one most people don't expect.
Therapy first, and that's a strong recommendation
The guideline strongly recommends individual trauma-focused psychotherapy over medication. The reasoning given is that trauma-focused psychotherapies produce greater improvement in core PTSD symptoms than drugs do, and the improvements last longer.
Three therapies carry a strong recommendation:
- Cognitive processing therapy (CPT) — works on the beliefs the trauma installed, particularly around blame and safety
- Prolonged exposure (PE) — graded, deliberate approach to the memory and to avoided situations
- EMDR — eye movement desensitisation and reprocessing
Several others are suggested more weakly, including Ehlers cognitive therapy, present-centred therapy and written exposure therapy — the last of which matters practically, because it is briefer and easier to deliver where access is limited.
The single most useful sentence in this article: when you seek help, ask specifically whether the therapist delivers CPT, PE or EMDR. Generic counselling is not the same thing, and asking that one question filters a great deal.
Medication, where it fits
Three medicines carry strong recommendations: paroxetine, sertraline and venlafaxine. They work, they are a reasonable option — particularly where therapy isn't accessible or someone doesn't want it — and the guideline still puts therapy ahead of them.
Prazosin is worth knowing about because it is often raised for nightmares specifically. The guideline gives it a weak recommendation for nightmares, while suggesting against it for PTSD overall — a precise distinction that reflects genuinely mixed trial results.
Two things the guideline strongly recommends against
Benzodiazepines. Strongly recommended against — lack of benefit, risk of misuse, and reduced effectiveness of the treatments that do work. That last part is the important one: a drug that blunts anxiety can undermine the exposure-based learning that trauma-focused therapy depends on. So it isn't neutral, it's counterproductive.
Cannabis and cannabis-derived products. Also strongly recommended against, on the basis of an absence of well-designed trials and the potential for serious adverse effects. This is worth stating plainly because PTSD is one of the conditions most heavily targeted by cannabis and CBD marketing, and because self-medication in PTSD is extremely common.
If you are currently prescribed a benzodiazepine, none of this is an instruction to stop. Stopping abruptly is dangerous. It is a planned conversation with the prescriber.
Sleep, and where the honest overlap with us sits
Sleep is wrecked in PTSD in two distinct ways — insomnia from hyperarousal, and nightmares that make sleep something to avoid. Both are miserable and both are among the most commonly self-treated symptoms of the whole condition.
Two distinctions worth having. Nightmares are REM-sleep events with vivid recall, and they are not the same as night terrors, which come out of deep sleep with no memory. And if sleep is a full night that leaves you unrefreshed rather than a night you can't get, screen for sleep apnea — it's common, it's independent of PTSD, and it worsens everything.
For insomnia itself, CBT-I has better evidence than anything you can buy, and it has been adapted for use alongside PTSD treatment. The stress-sleep loop is running here too, with more force than usual.
Where we sit — and the specific trap
Nothing Proco sells treats PTSD. No supplement does, and there is no supplement anywhere in the recommendations above.
We want to be specific about the failure mode rather than leave it at a disclaimer, because someone with undiagnosed PTSD is close to an ideal customer for a company like ours. They have hyperarousal, insomnia, poor concentration and a strong preference for handling it themselves rather than talking about it. That profile buys sleep products and calm products, repeatedly, and gets a marginal effect, and the avoidance that is a core feature of the disorder is quietly reinforced by having something to take instead of something to do.
We would rather lose that order. It is the same structure as selling sleep supplements to someone with sleep apnea, with the added problem that here the purchase can substitute for the treatment.
One practical safety note if you are on medication for this: Sleep Support contains St John's Wort and 5-HTP, both of which interact with SSRIs and SNRIs — including the three medicines named above. The full interaction list for our range is here, and it's a pharmacist conversation before combining anything. Alcohol is the other common self-medication route and it doesn't combine well either.
Related, and often confused
Grief is not PTSD. Bereavement produces intrusive memories, sleep disruption and concentration problems without being a trauma disorder — what the research on grief and the brain shows is worth reading before applying the wrong framework.
Anxiety disorders overlap heavily but respond to different specifics — the distinctions are here, and the treatments ranked by evidence here. OCD has intrusive thoughts too, and needs its own specific therapy rather than a trauma-focused one.
And chronic pain co-occurs with PTSD far more often than chance — plausibly through shared effects on how the nervous system processes threat signals. If both are present, both need addressing, and treating one while ignoring the other tends to stall.
If you recognise yourself
Go to a GP, say the word trauma, and ask about referral for CPT, PE or EMDR by name. If you are told to wait and see, ask how long and what the review looks like — watchful waiting is a legitimate approach in the first weeks and is not a legitimate answer at six months.
And if the honest situation is that something happened recently and you feel terrible: that is usually not a disorder yet, most people do recover, and the useful things are sleep, people, safety and not making permanent decisions this week.
This article is not medical advice and cannot diagnose PTSD. Nothing here should be used to start, stop or change a prescribed medication — stopping benzodiazepines abruptly can be dangerous. If a traumatic event is affecting your daily life more than a month afterwards, that is a sufficient reason to see a doctor.
