Bipolar I
This is the classic form of the illness. Bipolar I leaves no doubt as to whether someone is in a manic (extreme elation) phase, as their behavior quickly escalates until they’re out of control. The person could end up in the emergency room or worse if left untreated. To qualify as having bipolar I, a person must have manic or mixed episodes that last at least 7 days, or manic symptoms that are so extreme that the individual requires immediate hospital care.
