[Manic-depressive psychoses. Chronic treatment with tricyclic antidepressive agents].

Long-course Tricyclic anti-depressing treatment affonds clinical healing--i.e. abolition of the recurrences--in melancolic unipolary periodic depressions. This treatment--T.A.T.C.--allows a good prevention of melancolic recurrences in bipolar periodic patterns of psychosis. For the authors Lithium and/or Dipropylacétamide are not sufficient protection for melancolic or maniac recurrences in this patterns. It seems to be three patterns in fact: pure melancolic, pure maniac, and maniaco-depressive. Therapeutic and psychopathologic considerations.
