MRI evidence of past cerebral microbleeds in a healthy elderly population
Abstract
BACKGROUND: Incidental foci of signal loss suggestive of past microbleeds are a frequent finding on gradient-echo T2-weighted MRI of patients with nontraumatic intracerebral hemorrhage and have been associated with bleeding-prone microangiopathy. If and to what extent such lesions may also occur in the normal population is unclear. OBJECTIVE: To determine focal hypointensities in asymptomatic elderly individuals and their relation to other clinical and morphologic variables. METHODS: T2-weighted MRI of the brain was performed in a consecutive series of 280 participants (mean age 60 years, range 44 to 79) of the Austrian Stroke Prevention Study. This cohort consisted of randomly selected individuals without history or signs of neuropsychiatric disorder. RESULTS: Past microbleeds ranging from one to five foci of signal loss were seen in 18 (6.4%) individuals. They were strongly associated with higher age, hypertension, and lacunes (p < 0.001), and extensive white matter damage was more frequently noted (p = 0.02). Hypertension was present in all individuals with focal hypointensities in the basal ganglia and infratentorially but in only 5 of 10 volunteers with microbleeds limited to cortico-subcortical sites (p = 0.04). CONCLUSIONS: MRI evidence of past microbleeds may be found even in neurologically normal elderly individuals and is related, but not restricted, to other indicators of small vessel disease. The predictive potential of this finding regarding the risk of intracerebral bleeding requires further investigation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
