Strokes can happen at any age. They have no limit.
A Brain arteriovenous malformation (AVM) occurs when a tangle (like a ball of wires) of arteries (which are designed to carry high flowing blood coming from the heart) connects directly to veins (which are designed to carry low flowing blood slowly back to the heart) without any capillaries (the smallest type of blood vessels, thinner than a strand of hair) which are suppose to be in between arteries and veins. Arteries, being high flow, should never connect directly to veins, which have a low flow, as it puts excessive pressure on the vein walls. Without capillaries, which reduce blood flow pressure, the high-pressure blood from the arteries causes the veins to weaken over time, potentially leading to vessel rupture and a brain bleed.
