Stress-related disorders

Stress-related disorders constitute a category of mental disorders. They are maladaptive, biological and psychological responses to short- or long-term exposures to physical or emotional stressors. The National Institute of Environmental Health Sciences categorizes obsessive–compulsive disorder (OCD) and post-traumatic stress disorder (PTSD) as stress-related disorders. However, the World Health Organization's ICD-11 excludes OCD but categorizes PTSD, complex post-traumatic stress disorder (CPTSD), adjustment disorder as stress-related disorders.
