Although they are predominantly used in the treatment of bipolar disorder, mood stabilizers may be prescribed for a variety of other conditions, including:

• Cyclothymia. A milder mood disorder characterized by frequent lower-grade mood swings.
  
  
• Borderline personality disorder (BPD). Because of their effectiveness in treating aggression and impulse control, mood stabilizers may be used in the treatment of BPD.
  
  
• Mood instability due to other causes. Patients with other conditions that may cause mood problems may be prescribed mood stabilizers as adjunct medications.
