Subarachnoid hemorrhage

convulsions, mental disability and tunnel vision. It can also be called “Water on the brain.” Hydrocephalus can be inherited or acquired factors. This includes Spina Bifida, Craniosynostosis and Vein of Galen malformations. For acquired causes hemorrhage,head trauma,tumors and cysts. There are two types of Hydrocephalus that are called non-communicating Hydrocephalus and communicating Hydrocephalus, although there is some things/ people that say communicating forms can lead to CSF flow.For…

ARACHNOID CYSTS DESCRIPTION Arachnoid cysts are cerebrospinal fluid covered by arachnoidal cells and collagen that may develop between the surface of the brain and the cranial base or on the arachnoid membrane, one of the three membranes that cover the brain and the spinal cord. CAUSES • The exact cause of arachnoid cysts is not known. Researchers believe that most cases of arachnoid cysts are developmental malformations that arise from the unexplained splitting or tearing of the arachnoid…

presses on certain areas of the brain (hemorrhage). Lack of oxygen and pressure from hemorrhaging can lead to brain damage. There are two types of hemorrhagic stroke, depending on where bleeding occurs. If bleeding occurs within the brain tissue, the condition is called an intracerebral hemorrhage. If bleeding occurs in the area between the brain and the membrane that covers the brain (subarachnoid space), the condition is called a subarachnoid hemorrhage. Hemorrhagic stroke is a medical…

What is a stroke? By definition, a stroke is also known as cerebrovascular accident (CVA) is the “sudden death of brain cells due to lack of oxygen”. In other words, a stroke is a form of brain attack. It is referred as a “brain attack” because it can occur or attack at any time and to anyone (for instances, kids, adults, and elders). This means that the brain is not getting enough oxygen. The reason for oxygen shortage could be because there is blockage of blood vessels that help transport…

Virchow-Robin (VR) spaces or perivascular spaces of the brain refer to spaces that accompany the cerebral vessels as they pass from subarachnoid space into the brain parenchyma. A few evident perivascular spaces can be considered normal at any age but many visible perivascular spaces are not. The relevance of visible perivascular spaces to SVD is shown by their presence in increased numbers in patients with white matter hyper-intensities and with symptomatic lacunar ischemic stroke. The…

Negligence in Emergency Departments: Who’s to Blame? Introduction Health care in the United States is a thriving industry that is exponentially growing, with expenses consuming approximately 17.4% of the nation’s Gross Domestic Product (GDP) (Martin et. al, 2016). In fact, health care related expenses reached $3 trillion in 2014, and an estimated $55.6 billion of that $3 trillion was spent solely on medical liability expenditures (Mello et. al, 2014). Recently published studies have shown that…

Acute bacterial meningitis is a bacterium that reaches the subarachnoid space as it travels through the bloodstream or through the sinuses or ears. The infection is usually within the subarachnoid space, but toxins from bacteria or white blood cells known as leukocytes can result in edema as well as even further damage to blood vessels. Symptoms show up usually as a headache or…

Stroke is a cerebrovascular accident with sudden onset of focal neurological deficits(s) from either infarction or hemorrhage within the brain. • Ischemic stroke (thrombotic or embolic); 87% • Hemorrhagic stroke (intracerebral or subarachnoid); 13% Risk factors • Age: >45 years; highest during the 7th and 8th decades • Male > Female (3:1), equalizes after menopause • Family history/genetics • Prior stroke or TIA • Smoking, heavy alcohol use, substance abuse (cocaine, amphetamines) •…

lack of oxygen. The main types of stoke are hemorrhagic, ischemic, and a transient ischemic attack. Hemorrhagic stroke is broken in to two types, and the most common is the intracerebral hemorrhage, when an artery in the brain bursts flooding the brain with blood. The second and less common subarachnoid hemorrhage, when bleeding occurs in the area between the brain and the thin tissue that covers it. An ischemic stroke and a transient ischemic attack are both caused by a blockage in the artery…
