Small brain lesions and incident stroke and mortality: a cohort study

My doctor in an offhand comment mentioned I had multiple white spots in my brain from previous small strokes. No explanation of what to do to recover from those or prevent more from happening. In my opinion he was totally worthless.

Although cerebral lesions 3 mm or larger on imaging are associated with incident stroke, lesions smaller than 3 mm are typically ignored.To examine stroke risks associated with subclinical lesions (<3 mm only, >=3 mm only, and both sizes) and white matter hyperintensities (WMHs). Very small cerebrovascular lesions may be associated with increased risks for stroke and death; presence of lesions smaller than 3 mm and 3 mm or larger may result in a particularly striking risk increase. Larger studies are needed to confirm findings and provide more precise estimates.
