title: Hydergine: a review of 26 clinical studies.
abstract: This report reviews 26 clinical drug trials which investigated the effectiveness of Hydergine, a dihydrogenated ergot alkaloid, used frequently in geriatric psychopharmacology. The methodological characteristics and significant results for each study are presented in outline form. In total, 32 symptoms were assessed in six or more studies. Therapeutic benefits following Hydergine treatment occurred in the areas of cognitive dysfunctions, mood depression, and the composite scores as measured by subjective clinical behavioral rating scales. It is suggested that the improvement reported in cognitive functions and mood depression is a reflection of the global change observed by clinicians in patients' overall behavior duirng the interview. This conclusion that Hydergine does produce some global improvement indicates that further research with Hydergine is warranted, provided more objective instruments are employed such as those described in the report.
