Which of the following is a symptom of Bipolar Disorder?

• A. Decreased energy
• B. Increased appetite
• C. Constant happiness
• D. Increase energy

Answer: (D)

Bipolar disorder involves mood swings that include periods of mania or hypomania, where energy and activity levels surge. Increased energy is a hallmark of manic episodes, and people often feel unusually energetic, talk more, sleep less, and take on more activities. Decreased energy can occur during depressive episodes, but the energy spike during mania is the characteristic symptom being tested here. Constant happiness isn’t typical because moods swing between highs and lows, and increased appetite isn’t a defining feature of the manic state. So the option describing increased energy best matches a symptom of bipolar disorder.
