One of two things can happen; the blood can clot and block circulation to that part of the brain, or the blood can continue to accumulate an create a hemorrhagic area and pressure within the brain on a vessel or surrounding brain structure. In either case, it can lead to an "evolving" stroke with temporary or permanent disability, depending on the area involved and the time until the blockage or pressure is remedied. Also, a generalized response of fluid accumulation around the brain (cerebral edema) can occur to increase pressure around the brain as a whole. A CT scan or MRI scan can determine the type, area and extent of bleeding to choose the appropriate treatment, which may include "clot-busting enzymatic" drugs, high-dose steroids (hydrocortisone or methylprednisolone) or diuretics to draw fluid away from the brain. Time is critical, since the brain uses the greatest amount of oxygen in the body (about 20% for a 3-lb organ, far more than the heart), consequently it is exquisitely sensitive to anoxia.
What else can I help you with?
What is intercranial hemorrhage?
an accumulation of blood that occurs within the brain
What machine used to check the brain for swelling or internal bleeding is a?
A CT scan, or computed tomography scan, is a machine used to check the brain for swelling or internal bleeding. It creates detailed cross-sectional images of the brain using X-rays to help diagnose conditions such as traumatic brain injury or stroke.
What is the most serious form of bleeding?
in the brain and internal bleeding
Jill developed swelling of the brain What type of injury did Jill suffer?
Jill likely suffered a traumatic brain injury, which can lead to swelling of the brain due to internal bleeding, blood clots, or damage to brain tissue. Other possible causes of brain swelling include infections, tumors, or strokes.
After a stroke is there bleeding at the mouth and nose?
Normally, no. A stroke is internal bleeding (in the brain) and not external.
What disabilities are associated with different areas of brain injury?
There are many different types of brain injury, depending upon the severity of the force upon the head, as well as which portion of the brain is affected. To simplify, brain injuries can be classified as traumatic or acquired, with additional types under each heading. All brain injuries are described as either mild, moderate, or severe. Traumatic Brain Injury Traumatic brain injury is a result of an external force to the brain that results in a change to cognitive, physical, or emotional functioning. The impairments can be temporary or permanent. Types of traumatic brain injury include: * Diffuse axonal injury. Shaking or strong rotation of the head causes brain structures to tear. Nerve tissue is disturbed throughout the brain. * Concussion. Caused by a physical force to the head that causes blood vessels to stretch and cranial nerves to be damaged. * Contusion. A result of a direct impact to the head, which causes bleeding on the brain. * Coup-contrecoup injury. The force to the brain is large enough to cause contusion at the side of impact, as well as the site opposite impact. * Penetration injury. The impact causes a foreign object to penetrate the skull. Acquired Brain Injury An acquired brain injury is an injury to the brain that is not hereditary, congenital, degenerative, or the result of birth trauma. Acquired brain injury generally affects cells throughout the entire brain. Types of acquired brain injury include: • Axnoxic brain injury. This occurs when the brain doesn't receive oxygen.• Hypoxic brain injury. This occurs when the brain receives some, but not enough, oxygen. Levels of Brain Injury The Glascow Coma Scale is used to describe the level of initial injury relative to the neurological severity caused to the brain. Mild traumatic brain injury occurs when loss of consciousness does not occur or occurs very briefly, and testing or scans of the brain seem normal. Moderate traumatic brain injury occurs when loss of consciousness lasts a few minutes to a few hours, confusion lasts for days or weeks, and physical, cognitive, and behavioral impairments are evident. Severe brain injury occurs when unconsciousness or coma lasts days, weeks, or months, and is characterized by permanent physical, cognitive, or emotional impairments.
Why does a person die if their heart gets pierced with a bullet?
Internal bleeding, a lack of suitable blood pressure, the hearts inability to pump blood to the brain, and often a body's reaction of shock to such an injury
Where in the body would a cerebral hemorrhage occurs?
A 'cerebral hemorrhage' means bleeding within the brain.
Pathophysiology of a head injury?
There are many different types of brain injury, depending upon the severity of the force upon the head, as well as which portion of the brain is affected. To simplify, brain injuries can be classified as traumatic or acquired, with additional types under each heading. All brain injuries are described as either mild, moderate, or severe.

What machine is used to check the brain for swelling or internal bleeding?
A CT scan or MRI machine is typically used to check the brain for swelling or internal bleeding. These imaging techniques allow doctors to visualize detailed structures of the brain to help make a diagnosis.
What is a subdural hematoma?
A subdural hematoma is a type of bleeding that occurs between the brain and its outer lining, the dura mater. It is usually caused by a head injury that results in the tearing of blood vessels. Subdural hematomas can lead to increased pressure on the brain and require medical intervention.
Impact of traumatic disruption to cranial nerves?
This would result in a Traumatic Brain Injury, or TBI. There are many different types of brain injury, depending upon the severity of the force upon the head, as well as which portion of the brain is affected.
