Which of the following is NOT a common mental health disorder?

Asthma is the correct answer as it is primarily a physical health condition rather than a mental health disorder. Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to difficulty in breathing. It relates to physical health and plays a role in the functioning of the respiratory system.

In contrast, depression, bipolar disorder, and psychosis are all recognized as mental health disorders. Depression involves persistent feelings of sadness and a lack of interest or pleasure in activities, bipolar disorder is characterized by mood swings that include emotional highs (mania or hypomania) and lows (depression), and psychosis refers to conditions that affect the mind, leading to a disconnection from reality, often manifesting through hallucinations or delusions. These disorders are classified under mental health and require psychological assessment and intervention, highlighting their distinction from physical health conditions like asthma.
