[Neurologic changes in the white matter of the brain in dementia].

Neuroradiologic white-matter lesions (WML) found in CT and NMR were evaluated in 30 demented patients and 12 dementia-free subjects aged over 65 years. NMR revealed more WML signs than CT. All NMR results of demented patients demonstrated abnormalities (brain atrophy and/or WML), while 15.4% patients with dementia had normal CT scan. WML in CT were found more often among male than female demented patients. No dependence between the intensity of dementia symptoms, age of subjects, age of onset of cognitive impairment, risk for vascular diseases, and the presence of WML in CT and NMR was found.
