Klaus Conrad (1905-1961): delusional mood, psychosis, and beginning schizophrenia.

Klaus Conrad's major contribution to the phenomenology of psychosis focused on the patient's experiences during the prodromal and early psychotic phases of schizophrenia. The literature in English concerning his work is sparse, in part because Conrad's work contains complex concepts that lose much in translation. This communication attempts to clarify Conrad's thought, especially as it pertains to the role of mood and delusions in beginning psychosis and its underlying neurobiology.
