The incidence of subarachnoid hemorrhage is 10 per 100,000 persons per year
Tornadoes always happen during thunderstorms. They cannot occur without them.
both are caused by subduction zones
Tornadoes can happen during any time of the year, but they are most common in late spring and early summer in the United States. This is when warm, moist air masses collide with colder air masses, creating the conditions necessary for tornado formation.
Rain occurs when water vapor in the atmosphere condenses into droplets and becomes heavy enough to fall to the ground. This condensation is often triggered by cooling of the air, which can happen when warm air rises and mixes with cooler air. Eventually, the droplets coalesce to form raindrops that fall due to gravity.

Subarachnoid hemorrhages are classified into two general categories: traumatic and spontaneous.
Traumatic brain injury is the leading cause of subarachnoid hemorrhages, so it follows that efforts to prevent head injury would prevent these hemorrhages.
Subarachnoid hemorrhages are classified into two general categories: traumatic and spontaneous.
Subarachnoid hemorrhage is a medical emergency that can result in a sudden, severe headache, nausea, vomiting, and loss of consciousness. It is often caused by a ruptured aneurysm in the brain, which can lead to complications such as stroke, brain damage, and even death if not promptly treated. Early detection and treatment are crucial in improving outcomes for individuals with subarachnoid hemorrhage.
subarachnoid hemorrhages are caused by blood being released by a damaged blood vessel and accumulating in the subarachnoid space.
Strokes are commonly caused by clots blocking a cerebral artery, and heparin would prevent more clots from forming. In contrast, you want clots to form in hemorrhages to stop the bleeding.
Multiple retinal hemorrhages-- Bleeding in the back of the eye.
In BRVO, the superotemporal branch vein is the most often affected vessel. Retinal hemorrhages follows,
A subarachnoid hemorrhage is an abnormal and very dangerous condition in which blood collects beneath the arachnoid mater, a membrane that covers the brain. This area, called the subarachnoid space, normally contains cerebrospinal fluid. The accumulation of blood in the subarachnoid space can lead to stroke, seizures, and other complications
Smoking is a major factor in increasing the odds of sustaining a subarachnoid hemorrhage
