What kind of doctor treats Cyclothymic Disorder?

A psychiatrist, a doctor who treats mental health conditions, usually cares for cyclothymic disorder. A psychologist or counselor may also help with talk therapy. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.

What is cyclothymic disorder?

Cyclothymic disorder is a mental disorder. It is a mild form of bipolar disorder, in which a person has mood swings over a period of years.

Doctors describe it as hypomanic and depressive symptoms that do not meet the full rules for bipolar disorder or major depression.

Symptoms

Symptoms may include any of the following:

  • Periods of extreme happiness and high activity or energy. These are called hypomanic symptoms.
  • Periods of low mood, activity, or energy. These are called depressive symptoms.
  • Impulsive behavior, racing thoughts, and more talking.
  • Hopelessness, tiredness, trouble sleeping, and loss of interest in things.

The mood swings last for at least 2 years. In children and teens, they last for at least 1 year. The mood swings are less severe than with bipolar disorder or major depression.

Symptoms are ongoing, with no more than 2 symptom-free months in a row.

Causes and who gets it

The causes are unknown. Major depression, bipolar disorder, and cyclothymia often occur together in families. This suggests that these mood disorders share similar causes.

Genes seem to play a strong part. Bad life events and negative thinking styles are also linked to mood problems.

It usually begins early in life. Men and women are equally affected.

How doctors diagnose it

The diagnosis is usually based on your mood history. Your health care provider may order blood and urine tests to check for medical causes of mood swings.

Doctors also rule out other causes. These include hormone problems, vitamin lack, infections, brain injuries, and harmful effects of some medicines or illegal drugs.

It can be mistaken for other conditions, so a careful exam matters.

Treatment

Treatments include mood-stabilizing medicine, talk therapy, or a mix. Some commonly used mood stabilizers are lithium and antiseizure medicines.

No medicine is approved by the FDA for cyclothymic disorder. Current research advises against antidepressants, because they can make symptoms worse.

Cognitive behavioral therapy, a type of talk therapy, has the strongest evidence of the talk therapies. Learning about the illness is also a key part of care.

Compared with bipolar disorder, some people with cyclothymia may not respond as well to medicines.

Joining a support group can ease the stress of living with it.

When to see a doctor

Contact a mental health professional if you have ups and downs that do not go away and affect work, school, or social life.

If you are thinking about harming yourself, call or text 988 (the Suicide and Crisis Lifeline) right away. You can also call 911 or go to the nearest emergency room. Do not delay.

How a direct primary care or concierge doctor fits in

A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care doctor can listen to your mood history, order blood tests to look for medical causes, and refer you to a mental health professional. They can also help with follow-up visits.

Common questions

Is cyclothymic disorder the same as bipolar disorder?

No. Its symptoms do not meet the full rules for bipolar disorder, and the mood swings are less severe than with bipolar disorder or major depression.

Can cyclothymic disorder turn into bipolar disorder?

Yes, it can. But fewer than half of people with cyclothymic disorder go on to develop bipolar disorder.

How long do cyclothymic mood swings last?

They last for at least 2 years in adults. In children and teens, they last at least 1 year. In some people it stays a long-term condition, and in others it fades with time.

Who gets cyclothymic disorder?

Men and women are equally likely to have it. It usually begins early in life.
