CISM is an abbreviation for "Critical Incident Stress Management". It is a type of psychological care for forces like firefighters an policemen after desasters.
They give patients opportunities to describe what happened and how they responded; they also let patients receive warmth and caring from their listeners, and help put memories of the event into a coherent narrative, allowing them to integrate the trauma into their overall lives.
CISM appears to be particularly helpful in preventing burnout and ASD in emergency service personnel, rescue personnel, police, and other caregivers who are involved in treating survivors of a traumatic event.
Many mainstream practitioners recommend holistic or naturopathic approaches to recovery from ASD, including good nutrition with appropriate dietary supplements and regular exercise.
