The diagnosis of cyclothymic disorder is never made when there is a history of mania or major depressive episode or mixed episode (as told in "Blueprints in Psychiatry" - "mood disorders").

The lifetime prevalence of cyclothymic disorder is 0. 4-1%. The rate appears equal in men or women, though women more often seek treatment.

Diagnostic Criteria

Diagnostic Criteria (DSM-IV-TR)

• During the first two years of the disorder, the patient has not fulfilled enough criteria to qualify as having either bipolar disorder or major depressive disorder. The Diagnostic and Statistical Manual of Mental Disorders' ( DSM) is published by the American Psychiatric Association Major depressive disorder, also known as major depression, unipolar depression, unipolar disorder, clinical depression, or simply depression
• Symptoms are present for at least two years: periods of hypomanic symptoms and periods of low mood that do not fulfill the criteria for major depressive disorder. Major depressive disorder, also known as major depression, unipolar depression, unipolar disorder, clinical depression, or simply depression
• The longest period the patient has been free of symptoms is two months.
• The disorder cannot be better explained as schizoaffective disorder, and it is not superimposed on schizophrenia, schizophreniform disorder, delusional disorder or psychotic disorder not otherwise specified. Schizoaffective disorder is a Psychiatric Diagnosis of neurobiological illness. Schizophrenia ( from the Greek roots schizein (σχίζειν "to split" and phrēn Schizophreniform disorder is characterized by the presence of criterion A symptoms of Schizophrenia.

Diagnostic Criteria (ICD-10)

A persistently unstable mood, involving many periods of mild depression and mild elation. The International Statistical Classification of Diseases and Related Health Problems 10th Revision ( ICD -10) is a coding of diseases and signs symptoms abnormal findings This instability usually develops in late adolescence and follows a chronic course, although moods may be within norms for months at a time. Mood swings are usually perceived by the individual as being unrelated to life events. The diagnosis is difficult to establish without a prolonged period of observation or an unusually good account of the individual's past behaviour. Because the mood swings are relatively mild and the episodes of mood elevation may be enjoyable, cyclothymia frequently fails to come to medical attention. In some cases this may be because the mood change, although present, is less prominent than cyclical changes in activity, self-confidence, sociability, or appetitive behaviour. If required, age of onset may be specified as early (in late teenage or the twenties) or later.

The essential feature is a persistent instability of mood, involving numerous periods of mild depression and mild elation, none of which has been sufficiently severe or prolonged to fulfill the criteria for bipolar disorder or recurrent depressive disorder. This implies that individual episodes of mood swings do not fulfill the criteria for any of the categories described under manic episode or major depressive episode. Mania (from Greek μανία and that from μαίνομαι - mainomai, "to rage to be furious" is a severe medical condition Major depressive episode is a key symptom of Major depressive disorder.

Differential Diagnosis

This disorder is common in the relatives of patients with bipolar disorder and some individuals with cyclothymia eventually develop bipolar disorder themselves. It may persist throughout adult life, cease temporarily or permanently, or develop into more severe mood swings meeting the criteria for bipolar disorder or recurrent depressive disorder in rare cases.

Causes

Cyclothymia appears to have a genetic contribution, which has been shown by a range of twin studies involving dizygotic (fraternal) and monozygotic (identical) twins. Twins are Offspring resulting from the same Pregnancy, either of the same or opposite Sex.

Psychosocial factors have also been implicated, for example stressful life events or living conditions, and interpersonal difficulties. In addition, some unsupported theories posit that the hypomanic episodes have meaning in the context of a person seeking to achieve goals or to avoid depression.

Treatment

Treatment for cyclothymia can include a variety of cognitive behavioral therapy techniques. See also Cognitive Therapy Cognitive Behavioral Therapy ( CBT) is an umbrella-term for psychotherapeutic systems that deal with cognitions interpretations Prescription drugs such as lamotrigine, lithium, and benzodiazepines, are often used to treat cyclothymia.
