PTSD

Post-Traumatic Stress Disorder (ICD-10: F43.1) is a severe anxiety disorder that develops in some people following exposure to an extremely threatening or horrific event. ICD-10 requires: exposure to trauma → followed by at least one month of symptoms including re-experiencing, avoidance, and either hyperarousal or emotional numbing.

Lifetime prevalence is approximately 3–4% in the general population; higher in those exposed to assault, combat, or sexual violence. Not everyone who experiences trauma develops PTSD — approximately 20% of trauma survivors go on to develop the condition.

PTSD can make people feel very nervous or "on edge" all the time. Many may be startled very easily, have a hard time concentrating, feel irritable, or have problems sleeping. They may often feel like something terrible is about to happen, even when they are safe.

Some people feel very numb and detached — finding it difficult to feel emotions or connect with others around them. Everyday situations or sensory cues that remind them of the trauma can suddenly trigger intense distress.

Yes. From Rethink Mental Illness: "Yes, post-traumatic stress disorder (PTSD) is a mental illness. It can develop after experiencing or witnessing trauma, but support and treatment are available to help people manage or recover."

PTSD can profoundly affect daily functioning, relationships, and physical health. It is associated with significantly elevated rates of depression, substance misuse, and suicide. In the UK, PTSD is recognised by NICE and qualifies for specialist mental health treatment.

Women are more likely to develop PTSD than men. About 8 of every 100 women (or 8%) and 4 of every 100 men (or 4%) will have PTSD at some point in their life. This is in part due to the types of traumatic events that women are more likely to experience — such as sexual assault — compared to men.

Most people who go through traumatic events may have a hard time adjusting and coping for a short time. But with time and by taking good care of themselves, they usually get better.

If the symptoms get worse, last for months or years, and affect their ability to function daily, they may have PTSD. The key distinction is persistence, severity, and functional impairment — not simply whether the trauma was distressing.

Some frameworks describe five stages of PTSD:

• Impact or Emergency Stage: Immediate reaction to the trauma — shock, disbelief, numbness
• Denial/Numbing Stage: Attempting to block out thoughts of the event; emotional detachment
• Rescue Stage (including Intrusive or Repetitive stage): Intrusive memories and flashbacks begin; the person oscillates between re-experiencing and numbing
• Short-term Recovery or Intermediate Stage: Beginning to process what happened; support is engaged; symptoms may fluctuate
• Long-term Reconstruction or Recovery Stage: Integration of the trauma into one's life narrative; symptoms diminish; functioning improves

ICD-10 F43.1 organises PTSD symptoms into three clusters — all must be present for diagnosis:

• Re-experiencing: Flashbacks, intrusive memories, vivid nightmares in which the trauma is replayed; intense psychological or physiological distress when exposed to reminders
• Avoidance: Avoiding thoughts, feelings, activities, places, people, or conversations that are reminders of the trauma
• Hyperarousal or emotional numbing: Hypervigilance, exaggerated startle response, difficulty concentrating, sleep disturbances, irritability; or persistent emotional blunting, detachment, and inability to feel positive emotions

Symptoms must persist for more than one month and cause significant impairment in functioning.

The most well-known sign is reliving the event. This can happen through intrusive memories, vivid nightmares, or feeling like the trauma is happening all over again — an intense experience sometimes described as a PTSD attack or flashback.

In response, a person will naturally try to stay away from reminders of the experience, which leads to the avoidance pattern that is the second major symptom cluster.

Diagnosis is made by a mental health professional based on clinical interview. DSM-5 criteria require at least one re-experiencing symptom, at least three avoidance symptoms, at least two negative alterations in mood and cognition, and at least two hyperarousal symptoms — for a minimum of one month.

ICD-10 F43.1 (used in UK clinical settings) requires re-experiencing, avoidance, and either hyperarousal or emotional numbing, following a traumatic event. Tools such as the PCL-5 (PTSD Checklist) are often used to screen and monitor severity.

A PTSD meltdown often involves sudden, intense anger, crying, shouting, panic, or emotional withdrawal triggered by trauma reminders. The person may feel overwhelmed, lose emotional control, and struggle to calm down quickly.

The physiological stress response (fight-or-flight) is activated — heart rate rises, breathing quickens, the prefrontal cortex (rational thinking) is temporarily overridden by the limbic system (emotional/survival response). This is not a voluntary reaction and is not within conscious control.

Negative changes in thinking and mood associated with PTSD include:

• Ongoing negative emotions of fear, blame, guilt, anger, or shame
• Memory problems, including not remembering important aspects of a traumatic event
• Feeling detached from family and friends
• Not being interested in activities you once enjoyed
• Feeling emotionally numb — unable to experience positive emotions
• Feeling that the future has been cut short or that normal life is impossible

The "PTSD stare" — also called a dissociative stare — is when someone appears physically present but is emotionally and mentally checked out. Their eyes look unfocused, disconnected, and empty.

This blank stare often happens when someone is overwhelmed by the flood of memories and emotions triggered by trauma. They may be experiencing a flashback or dissociative episode — their mind has temporarily retreated from the present moment as a protective mechanism. Gentle grounding (speaking their name softly, asking them to feel their feet on the floor) can help bring them back.

Yes. PTSD profoundly affects memory in two directions simultaneously:

• Intrusive over-recall: Traumatic memories are re-experienced in vivid, fragmented, and intrusive ways — flashbacks and nightmares replaying sensory details of the trauma (ICD-10 F43.1 re-experiencing criterion)
• Dissociative under-recall: Some people have difficulty recalling parts of the traumatic event, or experience gaps in memory (dissociative amnesia, F44.0)

The hippocampus — which consolidates memory — shows structural changes in PTSD. Stress hormones (cortisol, adrenaline) released during trauma alter how memories are encoded and stored, creating fragmented rather than cohesive memory traces.

Both C-PTSD and PTSD involve symptoms of psychological and behavioural stress responses, such as flashbacks, hypervigilance, and efforts to avoid distressing reminders. People with C-PTSD typically have additional symptoms, including chronic and extensive issues with emotion regulation.

ICD-11 (2019) introduced Complex PTSD (6B41) as a distinct diagnosis — it requires all PTSD symptoms PLUS disturbances in self-organisation:

• Emotional dysregulation: Difficulty managing emotions; explosive reactions or emotional shutdown
• Negative self-concept: Persistent feelings of worthlessness, shame, or being permanently damaged
• Relationship difficulties: Difficulty trusting others; patterns of feeling unsafe in close relationships

ICD-10 does not have a separate C-PTSD code — clinicians use F43.1 with supplementary codes. C-PTSD typically arises from prolonged, repeated trauma (e.g. childhood abuse, domestic violence, captivity) rather than a single discrete event.

Conditions that can be confused with or overlap with PTSD include:

• Acute stress disorder
• Complex PTSD
• Dissociative disorders (F44)
• Adjustment disorder (F43.2)
• Generalised anxiety disorder (F41.1)
• Depression (F32/F33)
• Panic disorder (F41.0)
• Specific phobias

Accurate differential diagnosis requires a careful trauma history and assessment of symptom onset timing relative to stressful events.

PTSD can be misdiagnosed as the symptoms or behaviours of other mental health conditions. Conditions such as anxiety, depression, acute stress disorder, and borderline personality disorder have similarities to PTSD.

Equally, PTSD itself is often missed — particularly in people who do not spontaneously report trauma history, or where symptoms manifest primarily as irritability, substance misuse, or somatic complaints rather than textbook flashbacks. Women are more likely to be misdiagnosed with depression; men with conduct problems or substance use disorder.

Chronic trauma (also called complex trauma) is when something highly stressful happens over and over again, or lasts a long time. Often when people talk about complex trauma, it refers to going through abuse or severe neglect as a child.

This type of trauma tends to be harder to recover from because: (1) it occurs during sensitive developmental windows; (2) the abuser is often a caregiver (disrupting attachment); (3) there may be no single "event" to process — the trauma is woven into daily childhood experience; (4) it typically produces C-PTSD rather than PTSD, requiring longer and more specialist treatment.

ICD-10 distinguishes between two separate diagnoses:

• Acute Stress Reaction (F43.0): A transient disorder arising within hours of trauma, resolving within days to weeks. Symptoms include shock, disorientation, narrowed attention, and autonomic arousal. No treatment is usually required beyond psychological first aid and safety.
• PTSD (F43.1): Symptoms persist for at least one month and significantly impair functioning. This is when formal trauma-focused therapy (TF-CBT or EMDR) is indicated.

Early intervention during the acute phase — psychological first aid, structured support, and avoiding harmful coping (alcohol, isolation) — can reduce the risk of progression to full PTSD.

The course of PTSD varies considerably between individuals. Although some people recover within 6 months, others have symptoms that last for 1 year or longer.

People with PTSD often have co-occurring conditions, such as depression, substance use, or one or more anxiety disorders. Untreated PTSD can become chronic. With evidence-based treatment (TF-CBT or EMDR), the majority of people show meaningful improvement — many achieve full remission.

PTSD triggers can be external or internal. They remind the person — consciously or unconsciously — of the traumatic event and activate the stress response as if the danger were happening now.

Common triggers include:

• External sensory cues: Loud noises, crowds, specific smells, places, physical contact, anniversaries of the event
• Internal cues: Certain thoughts, emotions, or physical sensations similar to those experienced during the trauma
• Media: News stories, TV programmes, social media content depicting similar events
• Interpersonal triggers: Conflict, raised voices, perceived threat from others

Yes. Research confirms that olfactory (smell) triggers for PTSD are highly specific to the trauma. Findings from a PMC study showed greater prevalence of distress to the odours of blood, fuel, burnt hair, and the scent of discharged gunpowder — but not to other equally unpleasant odours — suggesting these particular odours have personal salience linked to the traumatic memory.

The olfactory system has a direct route to the amygdala (the brain's threat-detection centre) without relay through the thalamus — which may explain why smell is such a potent trigger for trauma memories.

Blame of self or others is a common reaction to traumatic events and, in some cases, may be normative, justified, appropriate, and possibly helpful. Research shows that appraisals including blame are associated with PTSD severity and are a treatment target in Cognitive Processing Therapy (CPT).

People with PTSD may blame themselves (survivor's guilt, self-blame for not preventing the trauma) or others (the perpetrator, bystanders, authorities). Neither form of blame is irrational given their experience — but persistent, distorted blame is a "stuck point" that maintains PTSD and is addressed directly in trauma-focused therapy.

Shouting can activate the hyperarousal response in people with PTSD, triggering fight, flight, or freeze reactions that are entirely involuntary. This response, although a natural defence mechanism, can be particularly overwhelming for individuals with PTSD.

It can exacerbate their symptoms, intensify feelings of anxiety, and magnify their emotional distress — potentially causing them to relive their traumatic experiences. Raised voices may be a specific trauma trigger if the original abuse or threat involved shouting. Low, calm speech is always preferable when someone with PTSD is distressed.

Stuck points are negative thoughts and beliefs that create barriers to recovery. Examples include: "It's my fault; I should have done something differently" or "We should have gone left instead of right."

Other common stuck points include: "I should have seen it coming," "I can't trust anyone," "I'm permanently damaged," or "The world is completely unsafe." These are thoughts, not facts — but they feel absolutely true to the person. Cognitive Processing Therapy (CPT) directly targets and challenges stuck points through structured worksheets and Socratic questioning.

Research on mental disorders more broadly shows that half of all lifetime cases start by age 14 years and three quarters by age 24 years. PTSD onset follows trauma exposure and so tracks the age at which people are most likely to be exposed to assault, combat, and serious accidents — typically young adulthood.

Older adults are also affected, particularly veterans and those with histories of childhood trauma. PTSD in older adults may present differently — more often with somatic complaints and less overt re-experiencing — and is frequently underdiagnosed.

NICE guidelines (2018) recommend trauma-focused psychological therapies as first-line treatment:

• Trauma-Focused CBT (TF-CBT): A structured therapy addressing the meaning of the trauma, avoidance behaviours, and distorted cognitions. Typically 8–12 sessions of 60–90 minutes.
• EMDR (Eye Movement Desensitisation and Reprocessing): Processes traumatic memories using bilateral stimulation (eye movements, taps, or tones). Equivalent effectiveness to TF-CBT in head-to-head trials.

Both should be offered within 1–3 months of trauma. Medication (SSRIs — sertraline or paroxetine) is second-line, used when psychological therapy is refused or unavailable, or for comorbid depression.

The four main antidepressants effective for treating PTSD are:

• Sertraline (Zoloft) — SSRI; NICE first choice for medication
• Paroxetine (Paxil) — SSRI; FDA-approved for PTSD
• Fluoxetine (Prozac) — SSRI
• Venlafaxine (Effexor) — SNRI; evidence of efficacy comparable to SSRIs

Additionally, antipsychotic drugs (olanzapine, quetiapine, risperidone) are sometimes used as adjuncts when standard antidepressants are insufficient, particularly for nightmares and hyperarousal.

Grounding and relaxation techniques help calm the nervous system during a PTSD episode. Approaches include:

• Drip cold water on your wrists — activates the dive reflex, rapidly lowering heart rate
• Slow diaphragmatic breathing — 4 counts in, hold 4, out 6
• 5-4-3-2-1 grounding — name 5 things you can see, 4 hear, 3 touch, 2 smell, 1 taste
• Progressive muscle relaxation — systematically tense and release muscle groups
• Aromatherapy — certain scents can anchor the person to the present moment
• Physical movement — short walk or exercise to metabolise stress hormones

Positive coping strategies recommended by the VA:

• Learn about trauma and PTSD — understanding why symptoms happen reduces shame and increases self-compassion
• Talk to others for support — social connection is one of the strongest protective factors
• Practice relaxation methods — breathing, mindfulness, grounding
• Distract yourself with positive activities — exercise, creativity, nature
• Talk to your doctor or a counsellor — professional support for ongoing spirals rather than white-knuckling alone

PTSD can cause blackout-like episodes through dissociation — a trauma response that can create sudden memory gaps during intense stress. During a dissociative episode, a person may lose track of time, act on autopilot, or have no memory of what happened during the episode.

PTSD blackouts and substance-related blackouts can overlap — many people experiencing PTSD also struggle with alcohol or drug use as a coping mechanism, which can compound memory impairment. Dissociative blackouts are distinct from substance blackouts and typically reflect a functional (not structural) change in brain processing.

Recovery is the final stage of PTSD. It occurs when a person takes action to heal from trauma — seeking professional help, prioritising self-care, and gradually re-engaging with life. Symptoms reduce, sleep improves, and the intrusive re-experiencing lessens.

Recovery is rarely linear. Most people have setbacks — a trigger, a difficult anniversary, a life stressor — but with effective therapy and support, the overall trajectory is toward improved functioning and quality of life. Recovery does not necessarily mean forgetting what happened; it means integrating the experience so it no longer dominates daily life.

PTSD is a treatable condition; many people achieve full remission with evidence-based therapy. NICE states that trauma-focused CBT and EMDR produce significant symptom reduction in the majority of patients who complete treatment.

Some people — particularly those with Complex PTSD from chronic trauma — experience ongoing symptoms requiring longer-term support rather than a single treatment course. Early intervention produces better outcomes. With appropriate treatment, the vast majority of people show meaningful improvement in quality of life — even when symptoms don't disappear entirely, their impact can be greatly reduced.

People with PTSD may experience a heightened sense of danger, even when they are not actually at risk. This can involve being much more vigilant than usual — for example, constantly scanning their surroundings for potential threats or feeling the need to sit with their back against a wall in public places.

The world can feel fundamentally unsafe, unpredictable, and threatening. Trust is difficult. Other people may seem dangerous or unknowable. This isn't pessimism — it is the nervous system having been rewired by trauma to prioritise survival above all else.

PTSD makes it difficult to have close relationships. It can also make it hard to have an active sex life or enjoy intimacy. Sexual problems are common in people with PTSD, regardless of the type of trauma experienced.

This occurs because: physical closeness may trigger trauma memories; emotional numbing makes genuine connection difficult; hypervigilance creates constant "threat monitoring" that overrides relaxation and pleasure; and shame or self-blame (common in PTSD) erodes feelings of worthiness in relationships.

Avoiding reminders — like places, people, sounds, or smells — of a trauma is called behavioural avoidance. For example, a combat veteran may stop watching the news or using social media because of stories or posts about war or current military events.

Over time, avoidance tends to expand — the person needs to avoid more and more to feel safe. While understandable as a short-term coping response, avoidance maintains PTSD by preventing the nervous system from learning that reminders are safe — which is why exposure-based therapies (TF-CBT, EMDR) are the most effective treatments.

Scientists believe that crying can make you feel physically and emotionally better. "Having a good cry" is thought to rid the body of toxins and waste products which build up during times of elevated stress — so it is logical that a person with PTSD may cry much more often than someone without the condition.

The intense emotional pain, grief, and distress that come with PTSD — combined with being regularly overwhelmed by triggers — naturally produce tears. Some people with PTSD also experience the opposite: emotional numbing that prevents them from crying even when they want to.

PTSD symptoms can cause significant relationship problems. If family members are not aware that a loved one's feelings or behaviours stem from their PTSD symptoms, they may feel their loved one is unhappy with them, angry at them, or withdrawing deliberately.

For Complex PTSD specifically, the disturbances in self-organisation (emotional dysregulation, negative self-concept, relationship difficulties) directly affect the ability to form and maintain secure attachments. Cycles of closeness and withdrawal, difficulty with trust, and intense emotional reactions can strain even the most supportive relationships. Couples therapy alongside individual trauma treatment can help both parties understand and adapt.

Dating someone with PTSD requires patience, education, and clear communication. Key approaches include:

• Educate yourself about PTSD — understanding the condition reduces misinterpretation of symptoms as personal rejection
• Know their potential PTSD triggers — ask what helps and what doesn't
• Communicate openly and empathetically — create space to talk about needs without pressure
• Be understanding and patient — recovery is not linear; bad days are not setbacks
• Practice self-care — you cannot support someone else from empty reserves
• Set healthy boundaries — PTSD does not excuse harmful behaviour; boundaries are important for both parties
• Encourage professional treatment — gently, without ultimatums

Yes. The condition may manifest in anxiety-like symptoms, emotional numbness or dysphoria, anger and aggression, or some combination of those states. It can feel like the normal stress response is locked into permanent overdrive, and those with PTSD often find it difficult to function normally in everyday life.

Hypervigilance — constant scanning for threat — is exhausting and generates persistent worry even in safe environments. The nervous system has learned that danger can appear suddenly, without warning, so it stays on high alert. This is an adaptive response to a genuinely dangerous situation that has become mal-adaptive in everyday safety.

The wrong words can trigger someone with PTSD. For some people, loud noises, crowds, and flashing lights can trigger debilitating symptoms — but saying the wrong thing is also a powerful trigger. Phrases to avoid include:

• "Just get over it" — minimises a real, neurological condition
• "It could have been worse" — invalidates their specific suffering
• "I know how you feel" — unless you have PTSD, you don't
• "Why can't you just forget about it?" — PTSD is characterised by the inability to process and move on from the memory
• "You're so strong" — can communicate that they're not allowed to struggle

The worst thing you can do is invalidate their experience — making them feel isolated, ashamed, or misunderstood. Invalidation communicates that their suffering is not real, not serious, or is their own fault. This directly reinforces the shame and self-blame that are central features of PTSD and makes recovery harder.

Other harmful actions include: forcing them to talk about the trauma before they're ready; dismissing flashbacks as "just in your head"; exposing them to triggers deliberately to "help them get over it"; or threatening to leave if they don't recover faster.

Supporting someone with PTSD means understanding their unique neural bridges — those fragile connections between trauma and safety. The worst thing to do is to destabilise these bridges further through dismissive words, sudden actions, or ignoring their need for stability.

Specific things to avoid:

• Surprising or startling them suddenly (slamming doors, touching without warning)
• Pressuring them to attend triggering environments
• Discussing the traumatic event in detail without their invitation
• Being dismissive or minimising their avoidance behaviours
• Projecting your own emotions or needs onto their recovery timeline

When unwanted distressing memories, images, or thoughts arise, the VA recommends:

• Remind yourself that they are just memories — not the present moment
• Remind yourself that it is natural to have some memories of the trauma
• Talk about them to someone you trust
• Remember that, although reminders of trauma can feel overwhelming, they often lessen with time and treatment

People with PTSD often use a mix of adaptive coping (exercise, social support, therapy) and maladaptive coping (alcohol, avoidance, isolation). Treatment focuses on building adaptive strategies and reducing avoidance so that the nervous system can gradually learn safety.

Warning signs that a person with PTSD may be entering a flashback or dissociative episode include:

• Becoming very quiet and withdrawn suddenly
• Eyes becoming unfocused or glazed (the "PTSD stare")
• Breathing becoming shallow and rapid
• Flinching at sounds or touch
• Appearing confused about where or when they are
• Sweating, pallor, or shaking

Grounding techniques can help anchor the person to the present moment: ask them to name 5 things they can see, 4 they can hear, 3 they can touch. Speak calmly, don't touch without asking, and stay with them.

During a PTSD flashback:

• Stay calm — your regulated nervous system helps co-regulate theirs
• Use a calm, low voice: "You're safe. I'm here with you. This is [location], it's [year]."
• Don't touch without asking — unexpected touch can worsen dissociation
• Help them ground with simple sensory cues: "Feel your feet on the floor. Take a slow breath."
• Don't try to talk them through the memory in the moment — wait until they're fully grounded

Afterwards, ask what was helpful. Validate how difficult that was. Encourage them to mention the episode to their therapist or care team.

Seek urgent help immediately if the person:

• Expresses intent to end their life or harm others
• Is engaging in serious self-harm
• Loses contact with reality (psychotic episode)
• Is unable to keep themselves safe
