If you get a cut, for example, you know you need a Band-Aid to stop the bleeding. But hitting your head is less obvious. How can you know if your brain was impacted or not when you can’t see it?
The bleed can be very small without any significant effect on surrounding brain or large hemorrhage that exerts mass effect on adjacent brain. Follow up CT scan is recommended. Those with extension of bleed into the ventricular system , expansion of bleeding, or increasing cerebral oedema on CT scan gives poorer prognosis.
“The only two places that blood can go when you have a nosebleed are from the front of the nose or down the back of the nose and into the throat,” says Dr. Edwards.
Intraparenchymal hemorrhage can be recognized on CT scans because blood appears brighter than other tissue and is separated from the inner table of the skull by brain tissue. The tissue surrounding a bleed is often less dense than the rest of the brain because of edema, and therefore shows up darker on the CT scan. [30]
If a brain bleed is not treated quickly, it can lead to permanent damage, including memory loss, difficulty swallowing and speaking, coordination challenges, numbness or weakness in body parts ...
The interior of the skull has sharp ridges by which a moving brain can be injured. The most common cause of intracranial epidural hematoma is head injury, although spontaneous hemorrhages have been known to occur. Epidural hematomas occur in about 10% of traumatic brain injuries, mostly due to car accidents, assaults, or falls. [3]
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
The Brain Aneurysm Foundation reports that 1 in 50 people in the U.S. has an unruptured or intact aneurysm (an aneurysm in the brain that is not bleeding). However, the annual rate of an aneurysm ...
