What are the best criteria to determine who suffers from bipolar disorder and who is just an emotional person?

To determine if someone has Bipolar disorder rather than being simply emotional, clinicians typically assess the presence and duration of manic or hypomanic episodes alongside depressive episodes. Key criteria include distinct periods of elevated mood, increased energy, and impulsive behavior that last at least one week (or less if hospitalization is required), along with significant mood swings that disrupt daily functioning. Additionally, a thorough evaluation of the individual's history, family background, and the impact of mood changes on their life is crucial for an accurate diagnosis. Emotional individuals may experience mood fluctuations, but without the severe, episodic nature seen in bipolar disorder.
