  • A family history of mood disorder
  • Previous depression
  • Stressful events

SymptomsandDiagnosis

Symptoms

Symptoms of mood disorder can vary. They may be:

  • Lasting sadness, anxiety, or emptiness
  • Feeling hopeless, helpless, or guilty
  • Feeling tired, restless, or irritable
  • Problems sleeping
  • Loss of interest in sex, hobbies, and activities
  • Problems with memory, focus, or decisions
  • Changes in eating or weight
  • Thoughts of death or suicide

Sometimes there are physical symptoms. Examples are aches and pains that cannot be explained.

Diagnosis

The doctor will ask about symptoms and past health. A physical exam may be done. The doctor may give questionnaires. They will focus on mental health.

The doctor may want to rule out other conditions first. It may take time to diagnose a mood disorder.

Treatments

Treatment

The goal is to ease symptoms and improve function. Treatment depends on the type and severity of the condition. Severe mood disorders may need hospital care. Care is urgent if someone might hurt themselves or others.

A number of treatments may be used. Options may be:

  • Medicines, such as:
    • Antidepressants
    • Mood stabilizers.
  • Counseling—to help with coping
  • Lifestyle changes, such as:
    • A healthy diet
    • Daily physical activity—to ease symptoms and stress.
    • Limiting alcohol or drugs

Sometimes symptoms last, despite treatment. If symptoms are severe and lasting, options may be:

  • Electroconvulsive therapy—a brief electric pulse to the brain to help reset it
  • Vagus nerve stimulation (VNS)—an implanted device that may alter signals to the brain
  • Transcranial magnetic stimulation (TMS)—a device that sends pulses to the brain

Prevention

There are no current guidelines to prevent mood disorders. However, early treatment may help reduce how severe they are.
