Annie has frequent mood swings. she is hyperactive one moment and depressed soon after. in which disorder do patients exhibit such alternating behavior? anxiety disorder bipolar disorder attention deficit disorder autism schizophrenia

The correct answer is B. Bipolar disorder

Explanation:

Frequent and drastic mood swings such as being happy or hyperactive and then depressed without any cause are considered as abnormal behavior and are often an indicator of bipolar disorder. This disorder is characterized by periods of mania that imply high levels of energy, happiness or similar and periods of depression or negative feelings, although both periods can also be mixed. Additionally, the individual shifts from one period to another without a specific cause and has other abnormal behaviors such as suicidal thoughts or compulsive behaviors. Thus, the alternating behavior shown by Anna is common in bipolar disorder.
