Patients suffering from mania are overactive, intrusive, excited, and belligerent. They may believe that they have special powers, are related to public figures, and can read the minds of others. They spend money lavishly. Voices on the radio or television are sometimes understood as personal communications. They speak rapidly, with illogical and confused thoughts, move constantly, and write page after page of nonsense. They typically sleep and eat poorly, have little interest in work, friends, or family, and often require restraint or seclusion. Suicide is a perpetual threat. Some manic patients are likable, while others are angry and frightening. Psychosis is a frequent feature. Manic patients believe that their parents are not their real parents, asserting that they have royal blood. They believe that they can predict the future. They know that others are watching or talking about them, and they hear voices when no one is present. Delusional mania requires more intensive treatment and almost always hospital care. In older classifications of psychiatric illnesses, these patients were considered to be suffering from a manic-depressive illness. In modern classification, this term has been discarded and the illness is now conceived as bipolar disorder for patients with manic and depressive features and major depression for those with depressive symptoms only. Bipolar disorders, ranging from mild to severe, are divided into numerous subtypes. The variety of symptoms that admit the diagnosis of bipolar disorder has led to a virtual epidemic of diagnoses of the condition. Many patients so labeled do not exhibit the sleep difficulty, loss of appetite, and loss of weight, or the severity of illness, that were the criteria for manic-depressive illness. In manic-depressive illness, the manic episode persists for hours, days, weeks, or months and interferes with normal living. Once the episode resolves, it may suddenly recur; or manic episodes may alternate with periods of depression, or occur as simultaneous mixed episodes of depression and mania. When the shift in mood from mania to depression takes place within one or a few days, the condition is labeled rapid cycling, a particularly malignant form of the illness. In manic-depressive illness, the manic episode persists for hours, days, weeks, or months and interferes with normal living.
