Cyclothymia vs Dysthymia - Differences

Cyclothymia

Cyclothymic disorder, also referred to as cyclothymia, is a relatively mild form of bipolar disorder that is described by mood swings which may appear to be almost within the normal range of emotions.

It affects up to 1% of the population.

The manic symptoms of the disorder may include:

  • impulsive or reckless behavior;
  • extremely high self-esteem;
  • hypersexuality;
  • excessive talking or speaking very quickly, occasionally so fast others have trouble following what the sufferer is saying;
  • argumentative;
  • racing thoughts;
  • going for days with little or no sleep;

Notessymptoms typically start in adolescence or young adulthood.

During the lows, you feel mildly depressed. During the highs, the mood elevates for a time before returning to its baseline. In between the depressed and elevated moods, the patient is likely to feel like himself.

Complicationsanxiety

Possible complications include:

  • an anxiety disorder;
  • substance abuse;
  • there is a high risk of developing bipolar I or II disorder;
  • substantial emotional problems which affect every aspect of the sufferer’s life.

Causes

The disorder may result from a combination of:

  • environment, like – prolonged periods of stress or traumatic experiences;
  • differences in the way the brain works, like – changes in the brain’s neurobiology;
  • heredity, as the disorder tends to run in families.

The disorder is diagnosed when the following factors are present:

  • the symptoms are not a result of a physical illness or substance abuse;
  • the mood episodes are negatively impacting the day-to-day functioning of the patient;
  • the symptoms do not meet the diagnostic criteria for another illness, like – bipolar I, depression, or bipolar II disorder;
  • the patient had both depressive and hypomanic episodes for at least 24 months (12 months for children and adolescents), and these lows and highs account for at least 12 months;
  • the stable moods, that are the times between mood episodes, last for less than 60 days.

Treatment

It is essential to get help for the disorder as it can notably impact the everyday functioning as well as it affects the patient’s relationships at work and at home.

Treatment aims to:

  • stop the symptoms from coming back;
  • reduce the symptoms;
  • stop the disorder from developing into bipolar disorder.

Common treatments include:

  • Interpersonal and Social Rhythm Therapy – is a specific type of psychotherapy developed to help people with bipolar disorder; it involves a focus on the stabilization of daily rhythms, particularly related to wake, sleep, and mealtimes;
  • Dialectical Behavioral Therapy – it is a specific type of cognitive-behavioral psychotherapy that teaches distress tolerance, awareness, and emotional regulation;
  • Cognitive Behavioral Therapy – it is a short-term psychotherapy treatment which focuses on changing negative beliefs and thoughts into positive ones.

Note – no medications are approved by the US FDA specifically for the disorder, however, your healthcare provider may prescribe medications which are used to treat bipolar disorder, such as:

  • personality traits of the person – pessimistic, low self-esteem, anxious, and timid;
  • an alteration in neurotransmitters signaling;
  • environmental factors, like loss of a parent, emotional stress, financial difficulties, or abuse;
  • traits of the persistent depressive disorder tend to be observed in different generations in affected families.

Bottom Line – Cyclothymia vs Dysthymias

Cyclothymic disorder is a mild form of bipolar disorder, in which an individual has mood swings over a period of several years which go from emotional highs to mild depression.

This disorder causes emotional ups and downs, however, they are not as extreme as those in bipolar I or II disorder. Though less severe, it can have a notable impact on a sufferer’s life, where extreme mood changes disrupt the capacity to function healthfully.

Dysthymia is a form of depression that is less severe than major depression, however, it typically lasts longer. It may cause you to develop low self-esteem, lose interest in almost everything, and become incapable of living happily.

A key difference between cyclothymia and dysthymia is that a person with cyclothymia experiences emotional ups and downs with periods when she may feel stable and fine, whereas a person with dysthymia experiences ups and downs in mood, however, lower moods dominate and are persistent.
