OBJECTIVE: To measure the prevalence of computed tomography (CT)-detected cerebral lesions in a population-based sample of elderly persons living in Göteborg, Sweden. METHODS: Cerebral CT-scans were performed in the case of 466 women (mean age 74.3 +/- 5.1 years) and 191 70-year-old men. A single rater assessed white matter lesions (WML) using four different scales, lacunar lesions, large infarcts, cortical atrophy, and basal ganglia calcifications. RESULTS: White matter lesions frequency assessed by different scales ranged between 54.5% and 68.5%. Lacunar lesions were detected in 46.7% (30.1% had lacunes >5 mm) and cerebral infarcts in 3.0% of participants. Overall, 72.8% of participants evidenced cerebral vascular abnormalities. Severe cortical atrophy was more common in temporal (6.4%) and frontal (6.7%) lobes, than in parietal (1.7%) and occipital (1.1%) lobes. Basal ganglia calcifications were found in 38.7% of participants. WML, lacunar lesions, large infarcts, and degree of cortical atrophy correlated positively with age. More lacunes, basal ganglia calcifications, and occipital lobe atrophy were associated with male gender. CONCLUSIONS: Vascular and other brain lesions are very common on CT-scan in an elderly population, but large vascular lesions are rare. This study provides the first reference for the prevalence of CT-detected abnormalities in an elderly Swedish population.
