A FOLLOW-UP-STUDY OF PSYCHOLYTIC THERAPY WITH THE AID OF LSD

Psychotherapy with LSD was used at Modum Bads Nervesanatorium (MBN) fr om 1961, and in 1968 a questionnaire was sent out to the first 300 pat ients treated, in which they were to state results and experience of t he treatment, psychic condition, and treatment after the hospitalizati on at MBN. Because the question whether LSD influenced the chromosomes was topical at that time, a major part of the questions focused on he reditary influence. This unfinished study from 1968 is now completed. The follow-up study was answered by 239 patients (80%), 44% women and 56% men. Sixty-three per cent reported that the LSD psychotherapy had helped, and 38% stated that they were well at the time of the follow-u p. Ten per cent of the patients reported negative symptomatic effects of the psycholytic treatment. No connection was found between diagnosi s, age, and worsening of the symptoms. Among the obsessive neuroses, 1 5 (63%) of 24 patients stated that they had had a positive result of t he treatment, and 13 (54%) stated that they were well. For the obsessi ve neuroses, a distinct connection was found between the reported resu lt of the treatment and the number of treatments. One patient had trie d LSD on his own, but no indications of abuse among the patients were obtained. The study could not confirm any hereditary consequences of t he LSD treatment. In light of the methodologic limitations of the foll ow-up study, one cannot, even though the answers appear interesting, d ecisively conclude that the LSD psychotherapy had a treatment effect.
