The Chair of the University Nervenklinik in Homburg/Saar was held by Klaus Conrad from 1949-58 and by H.-H. Meyer, a former pupil and colleague of Kurt Schneider, from 1962-72. As the catchment area and admission policy of the clinic remained substantially unchanged throughout, comparison of the relative proportions of all admissions allocated to different diagnostic categories in 1949-58 and 1962-72 can be used to elucidate the similarities and differences between Conrad's and Schneider's diagnostic criteria. The results of this comparison indicate that Schneider's concept of schizophrenia was broader than Conrad's, and his concept of manic-depressive depression more restricted. More detailed comparisons are complicated by differences in nomenclature and in the varieties of functional mental illness recognized in the two periods. However, it seems that Conrad's concept of mania was wider only when the atypical schizophrenia-like psychoses diagnosed during the Conrad era were added to the Conrad-oriented cases of mania; when this was not done, the Schneiderian concept of mania was broader.
洪堡/萨尔大学神经科主任一职，1949年至1958年由克劳斯·康拉德担任，1962年至1972年由库尔特·施耐德的 former pupil and colleague（此处可能有误，推测为“ former pupil and colleague”可译为“ former pupil and colleague”）H.-H. 迈耶担任。由于该诊所的服务区域和收治政策在这期间基本保持不变，因此通过比较1949年至1958年和1962年至1972年分配到不同诊断类别的所有住院病例的相对比例，可用于阐明康拉德和施耐德诊断标准的异同。比较结果表明，施耐德的精神分裂症概念比康拉德的更宽泛，而他的躁狂抑郁性抑郁症概念则更狭窄。由于两个时期在命名法以及所认可的功能性精神疾病种类方面存在差异，更详细的比较变得复杂。然而，似乎只有当将康拉德时代诊断出的非典型精神分裂症样精神病添加到以康拉德为导向的躁狂病例中时，康拉德的躁狂概念才更宽泛；若不这样做，施耐德的躁狂概念则更宽泛。
