Subarachnoid Hemorrhage
Subarachnoid Hemorrhage
Abstract
Subarachnoid hemorrhages are more common than the public realizes. Asubarachnoid hemorrhageis a hemorrhage into the cerebrospinal fluid-filled space between the arachnoid and pia membranes on the surface of the brain.Trauma is the most common cause of subarachnoid hemorrhage. Some causes are vehicle accidents, aneurisms, sports, and falls. Some signs and symptoms of subarachnoid hemorrhage include headache, stiff neck, nausea, vomiting, slurred speech, impaired consciousness, loss of consciousness, and seizures. There are various ways of diagnosing subarachnoid hemorrhages among these are MRI, LP, and CT scans. Once discovered a subarachnoid hemorrhage needs to be treated right away. The most important part of treatment is time. The patient’s body must be allowed to attempt to heal on its own. If the hemorrhage does not stop on its own within 24 hours, surgery will be required. People who are conscious and demonstrate few neurologic symptoms when they reach medical help have the best outcome. There are many long term conditions that the individual will have to live with upon survival from fatigue to living in a vegetative state. Traumatic brain injury is the leading cause of subarachnoid hemorrhages, so it follows that efforts to prevent head injury would prevent these hemorrhages.
A subarachnoid hemorrhage is a hemorrhage into the cerebrospinal fluid-filled space between the arachnoid and pia membranes on the surface of the brain. The hemorrhage may extend into the brain if the force of the bleeding from the broken vessel is sudden and severe.
Trauma is the most common cause of subarachnoid hemorrhage. The leading causes of injury are bicycle, motorcycle, and automobile accidents, with a significant minority due to accidental falls, and sports and recreation mishaps. A subarachnoid hemorrhagecan lead to death or severe disability, even if recognized and treated early.
