An adjustment disorder is defined as a temporary state in which the person is unable to deal constructively with various stressful situations.
Due to this disorder, some people are suffering from sadness, which often leads to depression and anxious reactions, difficulties of concentrating, conduct disorders, tobacco addiction and suicidal thoughts.
An adjustment disorder can be caused by starting school, leaving home, marriage, parenting or retirement. Also, stressful life events like grief, separation experiences, migration as well as difficulties in relationships and work are a reason to have an adjustment disorder. There are cases where an adjustment disorder can be caused after a serious physical illness, for example after cancer, accidents and heart surgery.
