Which symptoms are NOT associated with major depressive disorder?

Persistent high moods, or mania, are not associated with major depressive disorder; rather, they are a hallmark of bipolar disorder. Major depressive disorder is characterized by persistent low mood, profound sadness, and a variety of cognitive and physical symptoms, including the inability to concentrate and suicidal thoughts. The presence of mania distinguishes bipolar disorder from major depressive disorder, allowing clinicians to accurately diagnose and administer appropriate treatment. Understanding the distinct symptoms of various mood disorders is essential for effective identification and intervention.
