[Assessment of brain atrophy by computer tomography (author's transl)].

Computer tomograms from 512 patients with brain atrophy were analysed according to standardized criteria. Exact studies of the outer and inner CSF spaces allowed a redefinition of this disease entity. The limits of change related to the physiological process of aging were established. In addition, an attempt was made to correlate CT findings with EEG tracings and psychiatric criteria.
