I know a vascular neurologist who says that the average age of his patients has dropped by nearly a decade in the last five years. Many more "young" (<60) men with minor strokes, and more frequent serious strokes in the 40s for both sexes. He's treated as many under 30 y/o stroke patients in the last two years than he did in the first two decades of his career. He's a few years from retirement and basically completely rattled by this sudden shift.
I have an out-there hypothesis I’d want to test. Much of the population has one or more MTHFR mutations, which can increase homocysteine if left untreated and that’s been linked to increased risk in stroke. Treatment includes more B vitamins. I wonder if the declining nutrition in foods and lack of B vitamins has anything to do with this.
i don't know how to word it better than: there's much we don't know yet about the extent of ~"long covid", or "down the road covid outcomes"
