During the manicky phase of this disorder, the patient may show excessive, unwaranted excitement or silliness, carrying jokes too far 5 . They may also show poor judgement and recklessness and may be argumentative. Manics may speak rapidly, have unrealistic ideas, and jump from subject to subject. They may not be able to sleep or sit still for very long. These symptoms are predominant for a specific period of time lasting for a few days or even a few months.
Hospitalization can often be necessary to keep the person from harming themselves and others.
The other side of the bipolar coin is the depressive episode. Bipolar depressed patients often sleep more than usual and are lethargic. This contrasts with those with major depression, who usually have trouble sleeping and are agitated. During bipolar depressive episodes, a patient may also show irritability and withdrawl. Manic episodes can occur without depression, but this is very rare.
