[Pseudo-organic defect in non-manifest schizophrenia]

On the basis of the material about 42 patients with non-manifest schizophrenia (slowly progressive in 32 cases and simple in 10 cases) the author presents a clinical and psychopathological description of mild pseudoorganic defect. It has been shown that the structure of the defect includes pseudoorganic disorders in the form of a reduction in the level of personality as well as Verschroben-like changes characteristic of schizophrenia. It has been elucidated that this variant of the defect is closely associated with the onset of the disease in childhood and a mixed nature of the dysontogenisis, including the signs of both dissociation and the retardation of mental development. This is confirmed by electroencephalographic findings suggesting a delayed maturation of the cortical electrical activity of the brain.
