In 1977 a questionnaire was sent to all psychiatric departments in the Nordic countries: Sweden, Norway, Denmark, Finland and Iceland, concerning indications for electroconvulsive therapy (ECT) and the use of unilateral and bilateral treatment, respectively. The inquiry was repeated in 1987 and the answers compared with those obtained in 1977. In addition, the answers from Denmark were compared with previously performed inquiries. The use of exclusively unilateral treatment (U) and of both unilateral and bilateral treatment (UB) has increased in most of the countries and exclusively bilateral treatment (B) has decreased drastically. In Denmark the situation has not changed for ECT in endogenous depression and acute delirium, and the use in reactive psychosis, mania and schizophrenia decreased somewhat during the 1970s and then again stabilized or increased during the 1980s. Nearly all departments in the Nordic countries used ECT in endogenous depression in 1977 and were still doing it in 1987. In mania, about 50% of all departments have found ECT indicated occasionally or exceptionally both in 1977 and 1987. Manic-depressive mixed states have been regarded as an indication in somewhat more than two thirds of departments, increasing during the period. The use of ECT in schizophrenia has been rare and somewhat decreasing, but still about half of the departments apply it once in a while. In reactive psychosis the use of ECT decreased slightly, but in 1987 it was still in use for this indication in about 50% of all departments. In acute delirium there has been an overall increase in the use of ECT.(ABSTRACT TRUNCATED AT 250 WORDS)
The treatment of choice for cycloid psychosis has traditionally been electroconvulsive therapy (ECT), but there is a lack of studies on its effectiveness.
The primary aim of this register study was to determine the rates of remission and response after ECT for cycloid psychosis. The secondary aim was to examine possible predictors of outcome.
Data were obtained from the National Quality Register for ECT in Sweden. The study population was patients (n?=?42) who received ECT for acute polymorphic psychotic disorder without symptoms of schizophrenia or for cycloid psychosis between 2011-2015 in 13 hospitals. Remission and response rates were calculated using Clinical Global Impression-Severity (CGI-S) and -Improvement scores, respectively. Variables with possible predictive value were tested using Chi-square and Fisher's exact test.
The response rate was 90.5%. The remission rate was 45.2%. Of 42 patients, 40 improved their CGI-S score after ECT (p?
