Treatment Options for Mood Disorders

1. Medications

A. Antidepressants

• Treat depression and anxiety symptoms.
• Classes:
  • Selective Serotonin Reuptake Inhibitors (SSRIs):
    • Examples: Sertraline, Fluoxetine, Escitalopram.
    • Commonly used due to fewer side effects.
  • Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs):
    • Examples: Venlafaxine, Duloxetine.
    • Effective for depression with physical symptoms like pain.
  • Tricyclic Antidepressants (TCAs):
    • Examples: Amitriptyline, Nortriptyline.
    • Older drugs with higher side effect profiles, used less frequently.
  • Monoamine Oxidase Inhibitors (MAOIs):
    • Examples: Phenelzine, Tranylcypromine.
    • Reserved for resistant cases due to dietary restrictions and interactions.

B. Mood Stabilizers

• Used in bipolar disorder to prevent mood swings.
• Examples:
  • Lithium (gold standard for bipolar disorder).
  • Valproate (Depakote).
  • Lamotrigine (Lamictal).
  • Carbamazepine (Tegretol).

C. Antipsychotics

• Treat mania or severe depression, often used as adjuncts.
• Examples:
  • Quetiapine (Seroquel).
  • Aripiprazole (Abilify).
  • Olanzapine (Zyprexa).

D. Anti-Anxiety Medications

• Benzodiazepines (e.g., Lorazepam, Diazepam) for short-term use in anxiety-related mood disorders.

2. Psychotherapy

A. Cognitive Behavioral Therapy (CBT)

• Focuses on identifying and changing negative thought patterns.
• Effective for both depression and bipolar disorder.

B. Interpersonal Therapy (IPT)

• Focuses on improving relationships and social functioning.

C. Dialectical Behavior Therapy (DBT)

• Useful for mood regulation and emotional distress.

D. Family Therapy

• Involves family members to improve communication and support.

3. Lifestyle Modifications

• Regular exercise: Boosts endorphins and reduces stress.
• Healthy diet: Maintains stable blood sugar and reduces inflammation.
• Sleep hygiene: Ensures adequate rest to prevent mood fluctuations.
• Stress management: Techniques like meditation and yoga.

4. Other Interventions

A. Electroconvulsive Therapy (ECT)

• Used for severe, treatment-resistant depression or mania.

B. Light Therapy

• Especially effective for Seasonal Affective Disorder (SAD).

C. Transcranial Magnetic Stimulation (TMS)

• Non-invasive procedure for depression not responding to medications.
