Influence of insulin treatment upon schizoid personality traits

Summary

Some interesting results of insulin shock treatment in three cases of paranoid dementia præcox are reported. Each case had certain well-marked schizoid prepsychotic personality traits. After the treatment, which seemed successful in each case, there was evidence that these schizoid traits had disappeared or had been modified. In one case the schizoid personality traits reappeared after two months without recurrence of active psychotic symptoms. The second case became psychotic again but in an extroverted, hypomanic way which contrasted strongly with his previous personality and psychotic reaction. In the third case the sociable, well-balanced attitude continues.
