[Clinico-pathogenetic aspects of hypochondriac conditions of exogenous-organic nature and their treatment]. 
Based on clinicopsychopathological and paraclinical examinations of 150 patients afflicted with organic diseases of the brain of infectious, traumatic and alcoholic nature, the clinical picture and formation of hypochondriac conditions were traced depending on the type of exogeny and the stage of cerebral sufferings.  It is shown that hypochondriac conditions develop by stages, namely from hypochondriac fixation to hypochondriac reaction and to the hypochondriac syndrome and that psychasthenic, vasovegetative and CSF dynamic disorders play the leading part in their establishment.  Seven varieties of the hypochondriac syndrome are distinguished.
