Silent brain infarctions

Clinically identified stroke represents the tip of the iceberg in terms of cerebral vascular disease by at least an order of magnitude...It is hard to believe, however, that loss of brain tissue should go without consequences. The brain may reorganize functional networks to adapt to lesions and recover function. But with each subsequent stroke, the capacity to do so is diminished.
--Brian J. Murray, MD

Scary new news on SBIs--one-fourth of persons with obstructive sleep apnea (the bedmate who keeps you awake as you wait for him to take his next breath) were found in a Japanese study to have evidence of extensive silent strokes on MRI imaging.
