Adjustment disorder is a mental illness or condition that is usually caused when a person experiences an extremely stressful event and has an excessively negative reaction. The condition is characterized by anxiety, reckless behavior, and inability to overcome the trauma.
Most cases of adjustment disorder are caused by an identifiable stressor. The affected person manifests an excessive reaction to the event or stressor. The cause of stress can be a single event such as a fire, losing a job, or divorce. For other people, the cause may be a dysfunctional family life or difficulties in the workplace.
