In a series of 25 patients on ataractic therapy and 25 other mental patients as controls, there was no essential difference in the incidence of increased protein or abnormal gold curves. The high incidence of abnormal findings in both of these groups, however, points to the possibility that these abnormal findings are unspecific and may also be found to a certain extent within the general healthy population. This study does not support the assumption that increased spinal fluid protein and abnormal gold curves are the result of ataractic therapy.Abstract Teaser
