PTSD risk factors

Many individual and societal risk factors can influence the likelihood of developing PTSD. Some of these factors are outlined in Table 1.⁷

Pathophysiology of PTSD

Multiple brain regions, pathways, and neurotransmitters are involved in the development of PTSD. Neuroimaging has identified volume and activity changes of the hippocampus, prefrontal cortex, and amygdala in patients with early trauma and PTSD. Some researchers have suggested a gross reduction in locus coeruleus neuronal volume in war veterans with a likely diagnosis of PTSD compared with controls.^16,17In other studies, chronic stress exposure has been found to cause neuronal cell death and affect neuronal plasticity in the limbic area of the brain.¹⁸

Diagnosing PTSD

More than 30% of individuals who experience ACEs develop PTSD.¹⁹The DSM-5 diagnostic criteria for PTSD are outlined in Table 2.²⁰ Several instruments are used to determine the diagnosis and assess the severity of PTSD. These include the Clinician-Administered PTSD Scale for DSM-5,²¹ which is a 30-item structured interview that can be administered in 45 to 60 minutes; the PTSD Symptom Scale Self-Report Version, which is a 17-item, Likert scale, self-report questionnaire; and the Structured Clinical Interview: PTSD Module, which is a semi-structured interview that can take up to several hours to administer.²¹

Other disorders. In addition to PTSD, individuals with ACEs are at high risk for other mental health issues throughout their lifetime. Individuals with ACE often experience depressive symptoms (approximately 40%); anxiety (approximately 30%); anger; guilt or shame; negative self-cognition; interpersonal difficulties; rumination; and thoughts of self-harm and suicide.²² Epidemiological studies suggest that patients who experience childhood sexual abuse are more likely to develop mood, anxiety, and substance use disorders in adulthood.^23,24

Psychotherapeutic treatments for PTSD

Cognitive-behavioral therapy (CBT) addresses the relationship between an individual’s thoughts, emotions, and behaviors. CBT can be used to treat adults and children with PTSD. Before starting CBT, assess the patient’s current safety to ensure that they have the coping skills to manage distress related to their ACEs, and address any coexisting substance use.²⁵
