3.10 What is Cyclothymia?
Diagnostic Criteria for Cyclothymic Disorder (DSM-IV, p. 365)
A. For at least 2 years, the presence of numerous periods with hypomanic
symptoms and numerous periods with depressive symptoms that do not meet
criteria for a Major Depressive Episode. Note: In children and adolescents,
the duration must be at least 1 year.
B. During the above 2-year period (1 year in children and adolescents), the
person has not been without the symptoms in Criterion A for more than 2 months
at a time.
C. No Major Depressive Episode, Manic Episode, or Mixed Episode has been
present during the first 2 years of the disturbance.
Note: After the initial 2 years (1 year in children and adolescents) of
Cyclothymic Disorder, there may be superimposed Manic or Mixed Episodes (in
which case both Bipolar I Disorder and Cyclothymic Disorder may be diagnosed)
or Major Depressive Episodes (in which case both Bipolar II Disorder and
Cyclothymic Disorder may be diagnosed).
D. The symptoms in Criterion A are not better accounted for by Schizoaffective
Disorder and are not superimposed on Schizophrenia, Schizophreniform Disorder,
Delusional Disorder, or Psychotic Disorder Not Otherwise Specified.
E. The symptoms are not due to the direct physiological effects of a substance
(e.g., a drug of abuse, a medication, or other treatment) or a general medical
condition (e.g., hyperthyroidism).
F. The symptoms cause clinically significant distress or impairment in social,
occupational, or other important areas of functioning.
