Overview of Mood Disorders

What are mood disorders?

A mood disorder is a class of mental health disorders. The term broadly describes all types of depression and bipolar disorders.

Children, teens, and adults can all have mood disorders. But children and teens don’t always have the same symptoms as adults. It’s harder to diagnose mood disorders in children. That's because they can't always express how they feel.

Therapy, medicines, and support and self-care can help treat mood disorders.

What are the different types of mood disorders?

These are the most common types of mood disorders:

  • Major depression. Having less interest in normal activities, feeling sad or hopeless, and other symptoms for at least 2 weeks may mean depression.

  • Dysthymia. This is an ongoing (chronic), low-grade, depressed, or irritable mood that lasts for at least 2 years.

  • Bipolar disorder. With this condition a person has times of depression alternating with times of mania or a higher mood.

  • Mood disorder linked to another health condition. Many health conditions (including cancer, injuries, infections, and chronic illnesses) can trigger symptoms of depression.

  • Substance-induced mood disorder. Symptoms of depression that are due to the effects of medicine, drug abuse, alcoholism, exposure to toxins, or other forms of treatment.

What causes mood disorders?

Many factors help lead to mood disorders. They are likely caused by an imbalance of brain chemicals. Life events (such as stressful life changes) may also help lead to a depressed mood. Mood disorders also tend to run in families.

Who is at risk for mood disorders?

Anyone can feel sad or depressed at times. But mood disorders are more intense and last longer. They are also harder to manage than normal feelings of sadness. Children, teens, or adults who have a parent with a mood disorder have a greater chance of also having a mood disorder. But life events and stress can expose or worsen feelings of sadness or depression. This makes the feelings harder to manage.

Sometimes life's problems can trigger depression. Things such as being fired from a job, getting divorced, losing a loved one, having a death in the family, and financial trouble, all can be difficult. Coping with the pressure may be troublesome. These life events and stress can bring on feelings of sadness or depression. Or they can make a mood disorder harder to manage.

The risk of depression in women is nearly twice as high as it is for men. Once a person in the family has this diagnosis, their siblings and their children have a higher chance of the same diagnosis.

What are the symptoms of mood disorders?

Depending on age and the type of mood disorder, a person may have different symptoms of depression. The following are the most common symptoms of a mood disorder:

  • Ongoing sad, anxious, or “empty” mood

  • Feeling hopeless or helpless

  • Having low self-esteem

  • Feeling inadequate or worthless

  • Excessive guilt

  • Repeating thoughts of death or suicide, wishing to die, or attempting suicide (Call 911. People with this symptom should get treatment right away.)

  • Not interested in normal activities or activities that were once enjoyed, including sex

  • Relationship problems

  • Trouble sleeping or sleeping too much

  • Changes in appetite or weight

  • Decreased energy

  • Trouble focusing

  • Less able to make decisions

  • Frequent physical complaints (for example, headache, stomachache, or tiredness) that don’t get better with treatment

  • Running away or threats of running away from home

  • Very sensitive to failure or rejection

  • Irritability, hostility, or aggression

In mood disorders, these feelings are more intense than what a person may normally feel from time to time. It’s also of concern if these feelings continue over time. Or if they interfere with someone's interest in family, friends, community, or work. Any person who has thoughts of suicide should get medical help right away.

The symptoms of mood disorders may seem like other conditions or mental health problems. Always talk with a healthcare provider for a diagnosis.

How are mood disorders diagnosed?

Mood disorders are a real health disorder. A psychiatrist or other mental health provider often diagnoses mood disorders with a complete health history and psychiatric evaluation.

How are mood disorders treated?

Mood disorders can often be treated with success. Treatment may include:

  • Antidepressant and mood-stabilizing medicines. These medicines work very well in treating mood disorders, especially when combined with psychotherapy.

  • Psychotherapy (most often cognitive-behavioral or interpersonal therapy). This kind of therapy is focused on changing the person’s distorted view of themselves and their environment. It also helps to improve relationship skills. And it can help the person find stressors in the environment and learn how to stay away from them.

  • Family therapy. A mood disorder can affect all aspects of a family (emotional, physical, and financial). Professional support can help both the person with the diagnosis and family members.

  • Other therapies. These may include electroconvulsive therapy and transcranial stimulation.

Families play a vital supportive role in any treatment process.

Someone with a mood disorder may have times of stability and times when symptoms return. Long-term, continuous treatment can help the person stay healthy and control symptoms.

When correctly diagnosed and treated, people with mood disorders can live, stable, productive, healthy lives.

Can mood disorders be prevented?

At this time, there are no ways to prevent or reduce mood disorders. But early diagnosis and treatment can reduce the severity of symptoms. It can also enhance the person’s normal growth and development, and improve their quality of life.
