Stroke in the context of "Averroes"

Neurology (from Greek: νεῦρον (neûron), "string, nerve" and the suffix -logia, "study of") is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the nervous system, which comprises the brain, the spinal cord and the peripheral nerves. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system, using various techniques of neurotherapy.

A neurologist is a physician specializing in neurology and trained to investigate, diagnose and treat neurological disorders. Neurologists diagnose and treat myriad neurologic conditions, including stroke, epilepsy, movement disorders such as Parkinson's disease, brain infections, autoimmune neurologic disorders such as multiple sclerosis, sleep disorders, brain injury, headache disorders like migraine, tumors of the brain and dementias such as Alzheimer's disease. Neurologists may also have roles in clinical research, clinical trials, and basic or translational research. Neurology is a nonsurgical specialty, its corresponding surgical specialty is neurosurgery.

Presidential elections were held in the United States on November 2, 1920. The Republican ticket of senator Warren G. Harding of Ohio and governor Calvin Coolidge of Massachusetts defeated the Democratic ticket of governor James M. Cox of Ohio and assistant secretary Franklin D. Roosevelt of New York. It was the first election held after the end of the First World War, and the first election after the ratification of the Nineteenth Amendment gave nationwide suffrage to women.

Incumbent president Woodrow Wilson, a Democrat who had served since 1913, privately hoped for a third term despite severe physical and mental disabilities from a stroke, but he had very little support. Former president Theodore Roosevelt had been the frontrunner for the Republican nomination, but he died in 1919 without leaving an obvious heir to his progressive legacy. The major parties turned to little-known dark horse candidates from the state of Ohio, a populous swing state with many electoral votes. Cox won on the 44th ballot at the 1920 Democratic National Convention, defeating William Gibbs McAdoo (Wilson's son-in-law), A. Mitchell Palmer, and several other candidates. Harding emerged as a compromise candidate between the conservative and progressive wings of the Republican party, and he clinched his nomination on the tenth ballot at the 1920 Republican National Convention.

Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception. In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking. The terms low vision and blindness are often used for levels of impairment which are difficult or impossible to correct and significantly impact daily life. In addition to the various permanent conditions, fleeting temporary vision impairment, amaurosis fugax, may occur, and may indicate serious medical problems.

The most common causes of visual impairment globally are uncorrected refractive errors (43%), cataracts (33%), and glaucoma (2%). Refractive errors include near-sightedness, far-sightedness, presbyopia, and astigmatism. Cataracts are the most common cause of blindness. Other disorders that may cause visual problems include age-related macular degeneration, diabetic retinopathy, corneal clouding, childhood blindness, and a number of infections. Visual impairment can also be caused by problems in the brain due to stroke, premature birth, or trauma, among others. These cases are known as cortical visual impairment. Screening for vision problems in children may improve future vision and educational achievement. Screening adults without symptoms is of uncertain benefit. Diagnosis is by an eye exam.

Vascular dementia is dementia caused by a series of strokes. Restricted blood flow due to strokes reduces oxygen and glucose delivery to the brain, causing cell injury and neurological deficits in the affected region. Subtypes of vascular dementia include subcortical vascular dementia, multi-infarct dementia, stroke-related dementia, and mixed dementia.

Subcortical vascular dementia occurs from damage to small blood vessels in the brain. Multi-infarct dementia results from a series of small strokes affecting several brain regions. Stroke-related dementia involving successive small strokes causes a more gradual decline in cognition. Dementia may occur when neurodegenerative and cerebrovascular pathologies are mixed, as in susceptible elderly people (75 years and older). Cognitive decline can be traced back to occurrence of successive strokes.

Joseph Stalin, second leader of the Soviet Union, died on 5 March 1953 at his Kuntsevo Dacha after suffering a stroke, at age 74. He was given a state funeral in Moscow on 9 March, with four days of national mourning declared. On the day of the funeral, of the hundreds of thousands of Soviet citizens visiting the capital to pay their respects, at least 109 were later acknowledged to have died in a crowd crush.

Stalin's body was embalmed and interred in Lenin's Mausoleum until 1961, when it was moved to the Kremlin Wall Necropolis. The members of Stalin's inner circle in charge of organizing his funeral were Nikita Khrushchev, then-head of the Moscow branch of the Communist Party; Lavrentiy Beria, head of the NKVD; Georgy Malenkov, the chairman of the Presidium; and Vyacheslav Molotov, previously the Soviet Union's Minister of Foreign Affairs.

Smoking cessation, usually called quitting smoking or stopping smoking, is the process of discontinuing tobacco smoking. Tobacco smoke contains nicotine, which is addictive and can cause dependence. As a result, nicotine withdrawal often makes the process of quitting difficult.

Smoking is the leading cause of preventable death and a global public health concern. Tobacco use leads most commonly to diseases affecting the heart and lungs, with smoking being a major risk factor for heart attacks, strokes, chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF), emphysema, and various types and subtypes of cancers (particularly lung cancer, cancers of the oropharynx, larynx, and mouth, esophageal and pancreatic cancer). Smoking cessation significantly reduces the risk of dying from smoking-related diseases. The risk of heart attack in a smoker decreases by 50% after one year of cessation. Similarly, the risk of lung cancer decreases by 50% in 10 years of cessation
