Magnetic Resonance Signal Abnormalities in Asymptomatic Individuals: Their Incidence and Functional Correlates

Fazekas F.
Department of Neurology and Psychiatry, Karl Franzens University, Graz, Austria


MR signal abnormalities were assessed in 87 symptom-free volunteers (31–83 years of age) and correlated with cerebrovascular risk factors, cerebral blood flow and glucose metabolism. Lesions in the subcortical and deep white matter increased from 11 % in the 4th decade to 83% in subjects over 70 years of age, and were detected significantly more often in individuals with cerebrovascular risk factors (p < 0.01). They were associated with lower slow-compartmental flow (p < 0.05) but did not affect adjacent cortical glucose metabolism. Periventricular signal changes also increased with age but were unrelated to risk factors or functional data.
