Popis: | The decrease in the frequency of diagnosed catatonic subtypes among schizophrenic disorders as a whole during the last 50 years has long been regarded as an established fact. Until now the factors responsible for this development have been under discussion. As it is not clear if there is a true decrease or an ostensible one due to other factors such as changed diagnostic habits or neuroleptic treatment, we examined 174 consecutively admitted schizophrenic patients from three different psychiatric institutions diagnosed according to DSM-IV and Leonhard's criteria. It turned out that-depending on the diagnostic system-the rates of diagnosed catatonias were 10.3% (DSM-IV) and 25.3% (Leonhard's criteria). Comparison of the two original Leonhard cohorts (1938 to 1968, 1969 to 1986) with our own (1994 to 1999) shows a decrease in the frequency of catatonias from 35% to 25%, which-albeit statistically significant-is much less pronounced than in studies that used a narrower definition of catatonia. Here, besides sociocultural developments, the use of neuroleptics seems to effect the decrease in the frequency of catatonias in two ways: on one hand, they cause a decrease of hyperkinesia, excitement, or impulsivity; while on the other hand, they themselves produce motor abnormalities like rigidity, effects that favor the attribution of motoric symptoms to neuroleptics. |
