Mood Disorders Explained

Mood disorders are mental health classifications used by professionals to broadly describe types of depression, bipolar, anxiety, and seasonal affective disorders. It is important to point out that emotions, feelings, and moods differ and are not interchangeable.

What Are Moods?

According to the American Psychological Association (APA), a mood is defined as:

“any short-lived emotional state, usually of low intensity (e.g., a cheerful mood or irritable mood). Moods differ from emotions in lacking an object; for example, the emotion of anger can be aroused by an insult, but an angry mood may arise when one does not know what one is angry about or what elicited the anger (Disturbances in mood are characteristic of mood disorders).”

Many factors contribute to mood disorders. They are likely caused by an imbalance of brain chemicals. Life events (such as stressful life changes) may also contribute 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. However, mood disorders are more intense and 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. However, 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. Being fired from a job, getting divorced, losing a loved one, death in the family, and financial trouble, to name a few, all can be difficult and coping with the pressure may be troublesome. These life events and stress can bring on feelings of sadness or depression or 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 brothers, sisters, or children have a higher chance of the same diagnosis. In addition, relatives of people with depression are also at increased risk for bipolar disorder .

Once a person in the family has a diagnosis of bipolar disorder, the chance for their brothers, sisters, or children to have the same diagnosis is increased. Relatives of people with bipolar are also at increased risk for depression.

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 (Note: People with this symptom should get treatment right away!)
  • Loss of interest in usual activities or activities that were once enjoyed, including sex
  • Relationship problems
  • Trouble sleeping or sleeping too much
  • Changes in appetite and/or weight
  • Decreased energy
  • Trouble concentrating
  • A decrease in the ability 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 interfere with one’s interest in family, friends, community, or work. Any person who expresses thoughts of suicide should get medical help right away.

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