The lasting effects of childhood trauma

Accelerated resolution therapy is a derivative of EMDR. It helps to reconsolidate the emotional and physical experiences associated with distressing memories by replacing them with positive ones or decreasing physiological arousal and anxiety related to the recall of traumatic memories.²⁸

Pharmacologic treatments

Selective serotonin reuptake inhibitors (SSRIs). Multiple studies using different scales have found that paroxetine, sertraline, and fluoxetine can decrease PTSD symptoms. Approximately 60% of patients treated with SSRIs experience partial remission of symptoms, and 20% to 30% experience complete symptom resolution.²⁹ Davidson et al³⁰ found that 22% of patients with PTSD who received fluoxetine had a relapse of symptoms, compared with 50% of patients who received placebo.

Serotonin-norepinephrine reuptake inhibitors (SNRIs) and other antidepressants. The SNRIs venlafaxine and duloxetine can help reduce hyperarousal symptoms and improve mood, anxiety, and sleep.²⁶ Mirtazapine, an alpha 2A/2C adrenoceptor antagonist/5-HT 2A/2C/3 antagonist, can address PTSD symptoms from both serotonergic pathways and increase norepinephrine release by blocking autoreceptors and enhancing alpha-1 receptor activity. This alleviates hyperarousal symptoms and promotes sleep.²⁹ In addition to having monoaminergic effects, antidepressant medications also regulate the hypothalamic–pituitary–adrenal (HPA) axis response to stress and promote neurogenesis in the hippocampal region.²⁹

Adrenergic agents

Adrenergic receptor antagonists. Prazosin, an alpha-1 adrenoceptor antagonist, decreases hyperarousal symptoms, improves sleep, and decreases nightmares related to PTSD by decreasing noradrenergic hyperactivity.²⁹

Beta-blockers such as propranolol can decrease physiological response to trauma but have mixed results in the prevention or improvement of PTSD symptoms.^29,31
