Answer to Question 2
In general, a person is said to suffer from bipolar disorder when both episodic depressed mood and episodic mania are present. The difference between the two is centered on the degree of mania. In bipolar disorder I, states of full- blown mania alternate with episodes of major depression. However, in bipolar disorder II, hypomania (less severe mood state than regular mania) alternates with episodes of major depression. Hypomanic states do not include the impulsive acts and gross lapses of judgment seen in mania. Bipolar II is more difficult to diagnose, as the patient may view hypomania as productive or creative periods.
