While recognising that each individual case of war neurosis must be treated on its merits, the Committee are of opinion that good results will be obtained in the majority by the simplest forms of psycho-therapy, i.e., explanation, persuasion and suggestion, aided by such physical methods as baths, electricity and massage. Rest of mind and body is essential in all cases.The committee are of opinion that the production of hypnoidal state and deep hypnotic sleep, while beneficial as a means of conveying suggestions or eliciting forgotten experiences are useful in selected cases, but in the majority they are unnecessary and may even aggravate the symptoms for a time. They do not recommend psycho-analysis in the Freudian sense.In the state of convalescence, re-education and suitable occupation of an interesting nature are of great importance. If the patient is unfit for further military service, it is considered that every endeavour should be made to obtain for him suitable employment on his return to active life. Return to the fighting line
Soldiers should not be returned to the fighting line under the following conditions:(1) If the symptoms of neurosis are of such a character that the soldier cannot be treated overseas with a view to subsequent useful employment. (2) If the breakdown is of such severity as to necessitate a long period of rest and treatment in the United Kingdom. (3) If the disability is anxiety neurosis of a severe type. (4) If the disability is a mental breakdown or psychosis requiring treatment in a mental hospital.
Modern cases of shell shock
Although the term "shell shocked" is typically used in discussion of WWI to describe early forms of PTSD, its high-impact explosives-related nature provides modern applications as well. During their deployment in Iraq and Afghanistan, approximately 380,000 U.S. troops, about 19% of those deployed, were estimated to have sustained brain injuries from explosive weapons and devices. This prompted the U.S. Defense Advanced Research Projects Agency (DARPA) to open up a $10 million study of the blast effects on the human brain. The study revealed that, while the brain remains initially intact immediately after low level blast effects, the chronic inflammation afterwards is what ultimately leads to many cases of shell shock and PTSD.
