People with manic depression experience periods of depression as described earlier, as well as periods of mania. There are a variety of effective treatments available for manic depression. There s no single cause of anxiety or depression. Some scientists believe that anxiety s a learned response, that people are taught to fear situations or objects. Some psychoanalytic theory suggests that anxiety stems from an unconscious conflict, an illness, fright or emotionally laden event that happened to the victim as a child.
Some medications can cause depression or mania, as can a medical illness.
Stress, like the loss of a loved one, a divorce or even a promotion at work, can all bring on depression or mania n susceptible individuals. In cases of depression where other treatments have failed or are not possible, electroconvulsive therapy has been used with success. But that s a fact that should help us understand those n need, not discourage them from seeking treatment. Depression, many doctors believe, s the underlying cause of most suicides. With proper treatment, the suffering can end.
