Cyclothymia - This is an affective mental disorder characterized by mood swings and which is very close to vague dysthymia, as well as hyperthymia with episodes of hypomania. Pathological changes in mood occur as a separate or dual episodes, separated by mental health states or their alternation, are characteristic of cyclothymia. This mental disorder is characteristic of a young age, and often turns into a protracted chronic course.
Cyclothmy usually manifests itself in spring or autumn. The duration of the individual phases of the disease reaches six months. Women get sick more often than men because of their tendency to melancholy. 25% of all ill people have only one phase of the disease.
Cyclothation, as a term, was often used to describe bipolar disorder, and in the traditional medical classification it was considered as one of the unexpressed variants of the cyclofrenia class.
In comparison, it is noted that the prevalence of cyclothymia is significantly higher than the psychotic affective disorders. But nevertheless, it is necessary to take into account that at the first signs of depression, up to 50% of the patients turn for help, 60% of which are treated by general practitioners, and the second half of people want to hide the symptoms of depression.
Hypomania in cyclothymia is often not perceived by people as a disease, especially if it is approaching hyperthymia. Much less often these states are in the field of view of psychiatric specialists. In this regard, a significant portion of patients are not diagnosed. Therefore, the real prevalence of cyclothymia is significantly higher than the figures given.
Cyclothymia includes cycloid personality disorders. German psychiatry refers to the disease all diseases of a manic-depressive nature, independent of the severity and the specific form of the disorder.
The term cyclothymia was proposed by K. Calbaum in 1882. Diseases of a neuropsychic tone with periods of fluctuations of unsharp excitement with weak pronounced depression were referred to this term. After Kraepelin attributed manic-depressive psychosis to the nosological unit, cyclotime was transferred to the central core of endogenous affective diseases. Further, non-psychotic and psychotic forms of bipolar disorder joined the disease.
