He's shorter-tempered than he used to be. He works late every night, barely sleeps and seems far away even when he's home. Friends say he's "just stressed." Sometimes that's true. But sometimes these are signs of PTSD in men that get missed for years, because they don't look like what people expect trauma to look like. This post explains what PTSD is, how it may show up in men, why it's so often mistaken for anger or personality and what an assessment and trauma counselling can offer.
This post is general information, not a diagnosis or a self-test. Only a qualified professional can assess PTSD.
What PTSD is, in plain terms
Post-traumatic stress disorder (PTSD) can develop after a person goes through, sees or learns about a frightening, shocking or dangerous event. The U.S. National Institute of Mental Health (NIMH) describes four groups of symptoms:
Re-experiencing: flashbacks, recurring memories or dreams, and physical signs of stress when reminded of the event
Avoidance: staying away from places, people or thoughts that bring the event back
Being on edge: being easily startled, feeling tense, trouble sleeping or concentrating, irritability or angry outbursts, and risky or reckless behaviour
Changes in mood and thinking: negative thoughts about yourself or the world, blame, guilt or shame, losing interest in things and feeling distant from others
The U.S. Department of Veterans Affairs' National Center for PTSD notes that most people who go through trauma don't develop PTSD, and that women are more likely to develop it than men. But many men do, and their symptoms are often overlooked.
Signs of PTSD in men that often get missed
Every man is different, and none of these signs on its own means someone has PTSD. Still, signs of trauma in men may look like:
anger, irritability or a short fuse
feeling numb, flat or "switched off"
working, training or staying busy non-stop so there's no quiet time
taking risks, like driving fast or picking fights
drinking more than before
poor sleep or bad dreams
always scanning for danger, sitting facing the door
pulling away from family and friends
The pattern matters more than any one sign, especially if it started or got worse after a hard experience.
If you or someone else is in immediate danger, call 911. If you're thinking about suicide, call or text 9-8-8 any time. Our crisis lines page lists both.
Why it gets mistaken for anger, stress or personality
Many men learn early to push through, keep it together and not talk about feelings. So instead of saying "I'm scared" or "I can't stop thinking about it," the distress comes out as anger, overwork or silence.
The National Center for PTSD explains that anger can be a natural survival response to extreme threat, and that it's especially common after trauma involving betrayal or violence. When anger is the most visible symptom, people may see a "bad temper" instead of a trauma response. Often, partners notice the change before the man himself does.
The kinds of trauma men often don't count
Many men don't think what happened to them "counts" as trauma. But PTSD isn't only about war. It can follow:
car crashes and serious accidents
physical assault or violence
sudden loss of someone close
frightening experiences at work
abuse or neglect in childhood
Our post on big T and little t trauma explains why both kinds of experiences can leave a mark. If you've been told to "get over it," that doesn't mean your experience wasn't real.
Physical signs of PTSD in men
Trauma lives in the body as well as the mind. The U.K.'s National Health Service (NHS) lists physical symptoms such as repeated headaches, stomach problems or pain with no clear physical cause, along with trouble sleeping and constantly looking for danger. NIMH notes that being on edge is often constant and can affect sleep, eating and focus.
Physical signs of PTSD in men might include tight shoulders, a clenched jaw, a racing heart around reminders, jumping at loud noises or always feeling tired. These are worth mentioning in an assessment, alongside how you've been feeling.
Signs of PTSD in young men and adult men
Symptoms of PTSD in men can look different at different stages of life. The NHS notes that symptoms may start right after a traumatic event or many months, or even years, later.
Signs of PTSD in young men may show up as risk-taking, partying hard, fights, trouble at work or study, or pulling away from friends.
Signs of PTSD in adult men may look more like overwork, irritability at home, emotional distance from a partner or kids and drinking to unwind.
Signs of complex PTSD in men
Some men have lived through trauma that went on for a long time, like childhood abuse or neglect, ongoing violence at home or repeatedly witnessing violence. The NHS explains that complex PTSD can follow these kinds of experiences, with symptoms that are largely the same as PTSD. Signs of complex PTSD in men can also include deep shame, trouble trusting people and feeling very different from others. An assessment can help sort out which description fits.
How it can affect partners and family
PTSD rarely affects only one person. Partners may feel shut out, walk on eggshells or take the irritability personally. Kids may notice a parent who seems far away or quick to snap.
None of this makes a man a bad partner or parent. Naming what's happening can be a relief for everyone. It also opens the door to repair: "I've been short with you lately. It's not about you. I'm working on it."
What an assessment can clarify
If you're unsure whether what you're living with is PTSD, stress or something else, that's exactly what an assessment is for. You don't need to be certain before you reach out. On our team, psychologists can assess and diagnose PTSD. Before booking, it can help to note:
what happened, in as much or as little detail as you're comfortable with
when changes in sleep, mood or temper started
what you avoid, and what helps you cope
anything family or friends have mentioned
How trauma counselling helps
Trauma counselling can help you understand your reactions, feel more settled in your body and talk about what happened at your own pace. Approaches such as EMDR and CBT-based trauma therapy are among the options our therapists use. Our trauma and PTSD counselling is available at our Kitchener-Waterloo, Cambridge and Ottawa offices, and online anywhere in Ontario.
Some men feel more comfortable talking to another man. We have therapists who are men at each of our offices, and our men's counselling page explains more. If you'd prefer online sessions, ask our admin team who is available online, since we can't guarantee a particular therapist's gender for online appointments.
Sessions with our therapists range from $130 to $200, depending on the clinician.
Depending on your plan, insurance may cover up to 100% of the cost. Coverage varies, so check your plan.
We accept Health Spending Accounts (HSAs).
We can direct bill many insurers, including for sessions with a Registered Psychotherapist (Qualifying). Desjardins is the exception: through TELUS eClaims, we can direct bill Desjardins for sessions with an RSW, RP or psychologist, but not for an RP (Qualifying).
Book a free 15-minute consultation with our admin team. "I think something from my past is still affecting me" is enough.
If you're in crisis: if you or anyone else is in immediate danger, call 911. If you're having thoughts of suicide, call or text 9-8-8 any time, day or night. Our crisis lines page lists both.
