Symptoms may include headache, pain over the temples, flu-like symptoms, double vision, and difficulty opening the mouth. Patients who present with symptoms of a lacunar stroke, but who have not yet had diagnostic imaging performed, may be described as having lacunar stroke syndrome (LACS). Cerebrovascular disease includes a variety of medical conditions that affect the blood vessels of the brain and the cerebral circulation. They usually cause no symptoms except when ruptured. McCormack and colleagues first used the term "fibromuscular hyperplasia" in the setting of hypertension and renal artery stenosis in 1958. The Journal of Pediatrics is an international peer-reviewed journal that advances pediatric research and serves as a practical guide for pediatricians who manage health and diagnose and treat disorders in infants, children, and adolescents.The Journal publishes original work based on standards of excellence and expert review. This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. Abdominal aortic aneurysm (AAA) is a localized enlargement of the abdominal aorta such that the diameter is greater than 3 cm or more than 50% larger than normal. Subarachnoid hemorrhage results from a ruptured intracranial aneurysm. Essential hypertension (also called primary hypertension, or idiopathic hypertension) is the form of hypertension that by definition has no identifiable secondary cause. The prevalence of abdominal aortic aneurysm ("AAA") has been reported to range from 2 to 12% and is found in about 8% of men more than 65 years of age.

With the advent of antihypertensive agents, the incidence of hypertensive emergencies in the United States has declined from 7% to approximately 1% of patients with hypertension. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Rupture may result in pain in the A stroke is a medical condition in which poor blood flow to the brain causes cell death. Hypergraphia is a behavioral condition characterized by the intense desire to write or draw. Articles in There are a number of disorders that affect this system. Venous thrombosis is blockage of a vein caused by a thrombus (blood clot). [] In addition, the 1-year survival rate associated with this condition has increased from only 20% (prior to 1950) to a survival rate of more than 90% with appropriate medical treatment. One of the premier peer-reviewed clinical journals in general and internal medicine, Mayo Clinic Proceedings is among the most widely read and highly cited scientific publications for physicians.
