The Centers for Disease Control and Prevention defines post-traumatic stress disorder (PTSD) as an intense, uncontrollable emotional and physical reaction to a reminder of a traumatic event or distressing memories [4]. This abnormal response to triggers can last for days and even years after the harrowing incident or traumatic event.

How Do You Know If You Have PTSD?

Symptoms of posttraumatic stress disorder or PTSD include [18]:

  • Re-living symptoms: Triggers easily cause flashbacks, intense memories, and terrible nightmares of the incident. These can result in an extreme fight-or-flight response. You experience intense fear and panic attacks. You also develop chest tightness, palpitations, rapid breathing, and increased blood pressure, among others.
  • Avoidance symptoms: You avoid places, people, activities, things, and even thoughts and emotions that remind you of the traumatic event.
  • Increased arousal symptoms: Small things like loud noises and stressful events can easily startle and rattle you. You feel jittery, nervous, quick to anger, moody, and paranoid. You also develop sleep problems.
  • Increased mood and cognition symptoms: You develop negative thoughts and cognitive issues like the inability to focus, concentrate, remember things, or recall memories, especially of the traumatic event. You may also have distorted thoughts and emotions where you blame yourself and feel guilty for what happened.

To be diagnosed with PTSD, you must have [18]:

  • At least one symptom of re-experiencing or reliving the traumatic event or incident
  • At least one symptom of avoidance
  • At least two symptoms of increased reactivity or arousal
  • At least two symptoms of cognitive and mood problems

The prevalence of PTSD worldwide is about 3.9% of the general population. In people who had experienced trauma, the prevalence rate is higher at 5.6% [29].

Between 1989 and 2019, about 316 million adult war survivors worldwide had PTSD and/or major depression [8].

Wars affect people’s mental health. In Ukraine’s war, for example, even before the 2022 conflict started, Ukrainians were already dealing with PTSD [25].

PTSD Therapy and Treatment

Mental health professionals treat PTSD patients with medications and cognitive behavioral treatment such as exposure therapy, cognition therapy, as well as stress inoculation training.

Medications for PTSD

Percentage chart of effective medications for PTSD

Medications like paroxetine and sertraline are used in treating PTSD. In a double-blind, placebo-controlled trial [7]:

  • Continued sertraline treatment showed a 5% relapse rate, compared to a 26% relapse rate in patients receiving a placebo.

Excluding PTSD medications, researchers studied over a thousand medications. By calculating their incidence rate ratios (IRR), researchers found that 15 of them showed protection associations or strong protective effects on PTSD. Not only did they not increase PTSD risks, but they also reduced the risks by about 30% to more than 50%. These drugs show that their IRRs are biased in the protective direction. The higher the IRR, the more it leans toward the protective direction [11].

  • Propranolol: 0.63
  • Atomoxetine: 0.64
  • Dexmethylphenidate: 0.68
  • Dextroamphetamine: 0.73
  • Guanfacine: 0.64
  • Methylphenidate: 0.65
  • Acamprosate: 0.57
  • Disulfiram: 0.48
  • Naltrexone: 0.55
  • Nicotine: 0.63
  • Clonidine: 0.65
  • Cyproheptadine: 0.60
  • Hydroxyzine: 0.65
  • Prazosin: 0.33
  • Ramelteon: 0.57

Therapy for PTSD

Percentage chart of therapy duration for PTSD

A few weeks of CBT for PTSD may already help reduce symptoms. Several studies show that [7]:

  • 21% to 46% of PTSD patients who received CBT within six weeks showed a 50% decrease in the severity of their mental health problems.
  • According to a similar study, about 32% to 53% of PTSD patients who received at least 10 CBT sessions had a 50% reduction in the severity of their mental health problems.
  • 14% of PTSD patients didn’t continue psychotherapy, with exposure therapy having the highest dropout rate of 50%.

Cannabis and CBD for PTSD

Some PTSD patients also use cannabis and CBD for their symptoms and other mental health disorders.

CBD is a non-psychoactive cannabinoid that cannabis plants produce. Unlike THC which gets you high, CBD won’t induce any psychoactive or mind-altering effects.

Chart of how effective of cannabis and CBD for PTSD

  • PTSD sufferers who use cannabis are 2.57 times more likely to recover or no longer meet the PTSD criteria than those who are not using cannabis [3].

Percentage graph of CBD user patients reduce their PTSD symptoms

  • 91% of the participants in a study on CBD and PTSD showed a reduction in the severity of their PTSD symptoms [5].
  • 8% of American adults using CBD say they’re using it for their mental health conditions, including PTSD [16].

Untreated PTSD Statistics and Prognosis

Graph chart of treated and untreated PTSD patients

The symptoms of PTSD in people receiving treatment usually last about 36 months. In people not receiving treatment, this can go as long as 64 months [7].

Most PTSD sufferers report significant improvements in the severity of their PTSD symptoms. However, one-third of them never fully recover even with treatment [7].

Conclusion: Post Traumatic Stress Disorder Statistics 

6% of the general population will have developed PTSD at some point in their lives and 11% to 23% of the veterans will have experienced PTSD within a given year. The leading cause of PTSD is sexual violence at 33%, with women more affected than men by 9.7% and 3.6% respectively.

Cognitive behavioral therapy, talk therapy, and medications help reduce PTSD and other symptoms. Cannabis and CBD may also help in improving their mental health issues.
