New Atlas: Honda files patents for brand new, fuel injected two-stroke engine
Two-strokes are far simpler machines than four-stroke engines. They’re also lighter, easier to work on, and downright angrier, pumping out a lot more power per cubic centimeter of displacement, which ...
An ischemic stroke occurs when the blood supply to part of the brain is blocked or reduced. This prevents brain tissue from getting oxygen and nutrients. Brain cells begin to die in minutes. Another type of stroke is a hemorrhagic stroke. It occurs when a blood vessel in the brain leaks or bursts and causes bleeding in the brain. The blood increases pressure on brain cells and damages them.
The patient with a stroke will typically start therapies very early after a stroke, including physical therapy, occupational therapy, and speech therapy. A person can continue to recover from a stroke for many months after a stroke up to a year or even longer. This recovery is a very gradual process. But don't give up.
Causes The cause of a transient ischemic attack is similar to the cause of an ischemic stroke, which is the most common type of stroke. In an ischemic stroke, a blood clot blocks the blood supply to part of the brain. In a TIA, unlike a stroke, the blockage is brief and there is no permanent damage.
Carotid artery disease occurs when fatty deposits, called plaques, clog the blood vessels that deliver blood to the brain and head (carotid arteries). These clogged blood vessels increase the risk of stroke. Stroke is a medical emergency that happens when the brain loses all or much of its blood supply.
