Summary: | The concept of latent
schizophrenia was developed by
E. Bleuler
(1911)
and was further promoted in the studies of a number of research
psychiatric schools of Europe, the United States, Japan, and other countries. In Soviet
psychiatry, there is a long-established tradition of studying "soft" forms
of schizophrenia (
Kerbikov 1933
;
Rozenshtein 1933
;
Brukhanskii 1934
). In the
systematics of schizophrenia, developed by
Snezhnevsky
(1969)
and his colleagues, sluggish schizophrenia is viewed not as an
initial (prodromal) stage of schizophrenia, but rather an independent diagnostic category
characterized by a slowly progressive course, subclinical manifestations in the latent period,
overt psychopathological symptoms in the active period, and then by a gradual reduction of
positive symptoms, with negative symptoms predominating the clinical picture during patient
stabilization. Studies are reviewed examining the relationship of constitutional and genetic
factors to the clinical manifestation of sluggish schizophrenia. Finally, the importance of
methodological considerations and an examination of divergent factors in the U.S. and Soviet
concepts of schizophrenia are presented. |
