Hector is studying to become a psychologist. After reading a chapter on psychological disorders, he starts to feel that he may have some of the symptoms seen in people with mood disorders. His perception is described as what?

The correct answer is Bipolar Disorder

In bipolar disorder, people alternate between periods of very good mood (mania) and periods of irritation or depression. So-called "mood swings" can be very fast and occur very often or infrequently.

During a manic episode, a person with bipolar disorder can manifest both euphoria and irritability. Many people with bipolar disorder 1 spend long periods without symptoms between episodes of the disease. Some people may experience rapid symptoms of mania and depression.
