Atypical exogenous psychoses
By Thomas A. Ban
Exogenous psychoses which are displayed by other manifestations than delirium, epileptiform reactions, stupor or confused states (Bonhoeffer 1909). The term was introduced in 1909 by Karl Bonhoeffer in his paper Zur Frage der exogenen Psychosen. The most frequently encountered atypical exogenous reactions are: “dysthymic reactions”, “hallucinatory reactions”, “paranoid reactions” and ”schizophreniform reactions” (Ban and Ucha Udabe 1995).
