Adjustment Disorder is a reaction to a stressful event or situation that usually last less than six months until unless chronic. This can affect anyone, regardless of gender, age, race, or lifestyle especially during adolescence, mid-life, and late life.
Feelings of depression, anxiety or combination of both are typical symptoms. They start behaving against "rules and regulations" of family, work, or society. In some people, an adjustment disorder may manifest itself in such behaviors as skipping school, unexpected fighting, recklessness, or legal problems.
There are many different subtypes of adjustment disorders, including adjustment disorder with: depression, anxiety, mixed anxiety and depression, conduct, emotional disturbances, sadness, headaches or stomachaches, reckless driving, withdrawal, hopeless feeling, crying spells, nervousness, worry, fighting, moody. A person with an adjustment disorder with mixed disturbance of emotions and conduct would have a mixture of emotional and conduct problems.

This problem occurs when a person cannot cope with a stressful event and develops emotional or behavioral symptoms. The stressful event can be anything: personal, employment, family problems, accidents, and loss of someone dear, divorce, illness, detachment of someone or a simple incident.

Normal expression of grief, in bereavement for instance, is not considered an adjustment disorder. However it is very important that this disorder is diagnosed and treated as it may interfere with a person's social, job, or school functioning. Psychotherapy (counseling) is the treatment of choice for adjustment disorders, which is usually a short-term treatment. This helps to lessen or alleviate ongoing symptoms of adjustment disorder before they become disabling.
