[Protracted hypochondriacal states of cerebral-organic genesis].

On the basis of clinico-follow up studies of 67 patients with brain disorders the author distinguishes 4 types of the development of the process: long-termed sluggish, remittent, subacute-progressive without remissions and regressive. The author stresses the age significance, additional exogenic factor when sluggish and remittent types of development are replaced by continuous types with moderate progressiveness. The remote stage in the illness development is characterized by expressed mnestic-intellectual deterioration, mental and physical insufferability, chronic and periodic mood disturbances, sleep disturbances, increased sensory excitement, personality changes of a hypochondrical type.
