Some people experience these symptoms when they hear unexpected loud noises, which causes them to "[lose] their cool over minor everyday things". Other symptoms can include self-destructive actions such as excessive drinking or driving too fast and outbursts of anger or overwhelming guilt. Treatment Treatments used during WWII New treatment methods for PTSD emerged during WWII, likely due to the high demand for care, and the subsequent increase in investigation. Interestingly, despite little understanding of the mechanisms whereby PTSD happened, much of the early interventions by psychiatrists in the 1940s remain similar to the methods still used today, such as medications and group therapy. One early treatment plan, from 1944, suggests a three part treatment to PTSD through use of sedatives to secure rest; use of intravenous barbiturates to promote mental catharsis, thereby assisting in the recall of a suppressed episode and use of drugs acting directly on the autonomic nervous system. In addition to medication plans, another method that was utilized for PTSD during WWII was the principle of proximity, immediacy, and expectancy, or "PIE". In essence, the PIE method emphasized immediate action in the treatment of PTSD. While first treatment plans for PTSD were crude and simplistic, they represent the rapidly changing field of psychiatry that WWII initiated, as will be further discussed below. Broader impacts Divorce rates following WWII Following WWII, the high rates of shell-shocked veterans and prisoners of war (POWs) returning home largely impacted marital relationships. A correlation between war and higher divorce rates is typical, and extends to WWII vets, specifically ex-POWs since the rates of PTSD are much higher for this group. For example, it was found that 30% of POWs with PTSD experienced relationship problems, with only 11% of veterans without PTSD experiencing marital problems. Moreover, a different study found that being in active combat or on the front lines also increased likelihood of marital discord. From this, it can be suggested that those who have been in high stress situations, and have subsequently developed PTSD, have a higher prevalence of marital problems than those without PTSD. Those with PTSD likely have more marital problems due to slow adjustment back home, a lack of valuable communication/expression, intimacy problems, life disruption, economic problems, aggression, and lingering mental health impacts. Thus, the effects of PTSD on WWII vets were not isolated to the vets themselves, as evidenced through high rates of marital discord following
