A certain estrangement from the communal world has always been considered an integral part of disorders belonging to the schizophrenia spectrum. Bleuler who coined the very term “schizophrenia” famously listed autism as one of its fundamental features and described how these patients tended to withdraw from intersubjectivity and encase themselves with their inner life. Such difficulties maneuvering the social realm have transpired through the various descriptions given by the canonical authors of psychopathology since then. It is an integral part of key clinical concepts ranging from Minkowski’s “loss of vital contact with reality” over Blankenburg’s “loss of natural self evidence” to Rümke’s “Praecox Gefühl” and today it is reflected in the diagnostic manuals. Thus the DSM 5 lists impoverished personal relations as a possible criterion B for making the schizophrenia diagnosis and it includes a lack of close friends or confidants and excessive social anxiety as diagnostic criteria for schizotypal personality disorder.
