His treatment for war neurosis was simple: the patients were to be bullied and harassed until they returned to front line service.Earlier, during the Winter War, several Finnish machine gun operators on the Karelian Isthmus theatre became mentally unstable after repelling several unsuccessful Soviet human wave assaults on fortified Finnish positions.

Peacekeeping provides its own stresses because its emphasis on rules of engagement contains the roles for which soldiers are trained. Causes include witnessing or experiencing the following:

Constant tension and threat of conflict. Threat of land mines and booby traps. Close contact with severely injured and dead people. Deliberate maltreatment and atrocities, possibly involving civilians. Cultural issues. Separation and home issues. Risk of disease including HIV. Threat of exposure to toxic agents. Mission problems. Return to service. Pathophysiology
SNS activation
Many of the symptoms initially experienced by people with CSR are effects of an extended activation of the human bodys fight-or-flight response. The fight-or-flight response involves a general sympathetic nervous system discharge in reaction to a perceived stressor and prepares the body to fight or run from the threat causing the stress. Catecholamine hormones, such as adrenaline or noradrenaline, facilitate immediate physical reactions associated with a preparation for violent muscular action. Although the flight-or-fight-response normally ends with the removal of the threat, the constant mortal danger in combat zones likewise constantly and acutely stresses soldiers.
Adenosine’s receptors are competitively antagonized by methylxanthines such as aminophylline. Aminophylline competitively antagonizes the cardiac actions of adenosine at the cell surface receptors. Thus, it increases heart rate and contractility. Brand names
