Disorders that are characterized by persistent feelings of apprehension, worry, uneasiness or dread the source of which is frequently nonspecific or unknown to the individual which may be accompanied by restlessness, irritability, lack of concentration, difficulty sleeping, increased heart rate, shortness of breath and other physiological symptoms.

An expected and predictable reaction to combat experiences that is characterized by hyperstartle reactions (an exaggerated response to something like a loud noise), hypervigilance, problems concentrating, flashbacks, nightmares, sleep problems, depression, irritability and other difficulties that affect thought processes, emotions, behaviour and physical health. While they sound negative, some combat reactions are actually considered adaptive, notably hyperstartle and hypervigilance. Combat stress reaction is generally short-term and should not be confused with acute stress disorder, post traumatic stress disorder, or other long-term disorders attributable to combat stress, although any of these may commence as a combat stress reaction. Symptoms that continue for an extended period of time (weeks or months), become increasingly worse or include violent or self-destructive behaviour require immediate medical evaluation and assistance.
