Final answer:
If an individual experiences both depression and mania, the condition is diagnosed as Bipolar I disorder when full manic episodes are present, and Bipolar II disorder when hypomanic episodes occur. The answer is: d) Bipolar I disorder if there are full manic episodes, or b) Bipolar II disorder if there are hypomanic episodes.
Step-by-step explanation:
When depression and mania occur in the same individual, this condition can be diagnosed as bipolar disorder. There are different types of bipolar disorder, and the presence of at least one manic episode is necessary for a diagnosis of Bipolar I disorder. If the individual experiences hypomanic episodes (which are less severe than full mania) and periods of depression, they might be diagnosed with Bipolar II disorder. Cyclothymic disorder is characterized by less severe but longer-lasting periods of hypomania and depressive symptoms. Major depressive disorder is distinct in that it does not include episodes of mania or hypomania.
Given that the question specifies the individual experiences both depression and mania, the correct diagnosis would likely be either Bipolar I or Bipolar II disorder, depending on the severity and duration of the manic episodes. Therefore, in cases where both depressive and manic episodes occur, the answer is: d) Bipolar I disorder if there are full manic episodes, or b) Bipolar II disorder if there are hypomanic episodes.
