Bleuler’s theory

a theory proposing a basic underlying symptomatology for schizophrenia. It defined four fundamental symptoms required for a diagnosis of the condition; the more obvious manifestations of schizophrenia (e.g., delusions, hallucinations) were regarded as accessory symptoms (see secondary symptoms) because they are shared with other disorders. [Eugen Bleuler]
