[Praecox feeling in medicine]

In this work the idea of praecox gefüll or praecox feeling is resumed by H. C. Rumke in 1941 and by Minkowski in 1968 for patient with schizophrenia. The diagnosis is not done only by patient's examination and by symptoms, but also by diligent examination which the psychiatry does about himself. To perceive one and to diagnose by praecox feeling is a personal ability, but it is a training with ourselves: to be sensible of the "effect" of disease in us. The praecox feeling, attributed in psychiatry, may be expanded in other medical areas. Case report gives evidence about this.
