Algorithm for the treatment of mood disorders in Japan.

In order to establish algorithms for mood disorders in Japan, over 300 psychiatrists completed a questionnaire. They were asked to recommend various drug treatments for particular cases. The order in which the drugs were recommended was taken into consideration. References were made to the randomized double blind study conducted by the working group. Evidence was ranked according to its probability, with the addition of case reports and medical opinions, since conclusions derived from the randomized double blind study alone did not give a full representation. Japanese documentation was referred to as much as possible in order to represent Japanese characteristics. Algorithms were made for eight subtypes; acute mania, bipolar depression, mild or moderate, severe major depression, psychotic depression, rapid cycling bipolar disorder, dysthymic disorder and major depression with advanced cancer. Major depression and bipolar disorder algorithms are discussed in this paper. Clinical psychopharmacological evidence in Japan was insufficient to generate these algorithms for mood disorders. These algorithms may need revision according to future advances in clinical psychopharmacology. (Int J Psych Clin Pract 1999; 3: 277-285).
