A stroke is a medical condition in which poor blood flow to the brain results in cell death. There are two main types of stroke: ischemic, due to lack of blood flow, hemorrhagic, due to bleeding. Both result in parts of the brain not functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Signs and symptoms appear soon after the stroke has occurred. If symptoms last less than one or two hours it is known as a transient ischemic attack or mini-stroke. A hemorrhagic stroke may be associated with a severe headache; the symptoms of a stroke can be permanent. Long-term complications may include loss of bladder control; the main risk factor for stroke is high blood pressure. Other risk factors include tobacco smoking, high blood cholesterol, diabetes mellitus, a previous TIA, atrial fibrillation. An ischemic stroke is caused by blockage of a blood vessel, though there are less common causes.
A hemorrhagic stroke is caused by either bleeding directly into the brain or into the space between the brain's membranes. Bleeding may occur due to a ruptured brain aneurysm. Diagnosis is based on a physical exam and supported by medical imaging such as a CT scan or MRI scan. A CT scan can rule out bleeding, but may not rule out ischemia, which early on does not show up on a CT scan. Other tests such as an electrocardiogram and blood tests are done to determine risk factors and rule out other possible causes. Low blood sugar may cause similar symptoms. Prevention includes decreasing risk factors, as well as aspirin, surgery to open up the arteries to the brain in those with problematic narrowing, warfarin in those with atrial fibrillation. A stroke or TIA requires emergency care. An ischemic stroke, if detected within three to four and half hours, may be treatable with a medication that can break down the clot. Aspirin should be used; some hemorrhagic strokes benefit from surgery. Treatment to try to recover lost function is called stroke rehabilitation and ideally takes place in a stroke unit.
In 2013 6.9 million people had an ischemic stroke and 3.4 million people had a hemorrhagic stroke. In 2015 there were about 42.4 million people who had had a stroke and were still alive. Between 1990 and 2010 the number of strokes which occurred each year decreased by 10% in the developed world and increased by 10% in the developing world. In 2015, stroke was the second most frequent cause of death after coronary artery disease, accounting for 6.3 million deaths. About 3.0 million deaths resulted from ischemic stroke while 3.3 million deaths resulted from hemorrhagic stroke. About half of people who have had a stroke live less than one year. Overall, two thirds of strokes occurred in those over 65 years old. Strokes can be classified into two major categories: hemorrhagic. Ischemic strokes are caused by interruption of the blood supply to the brain, while hemorrhagic strokes result from the rupture of a blood vessel or an abnormal vascular structure. About 87 % of strokes are ischemic. Bleeding can develop inside areas of ischemia, a condition known as "hemorrhagic transformation."
It is unknown how many hemorrhagic strokes start as ischemic strokes. In the 1970s the World Health Organization defined stroke as a "neurological deficit of cerebrovascular cause that persists beyond 24 hours or is interrupted by death within 24 hours", although the word "stroke" is centuries old; this definition was supposed to reflect the reversibility of tissue damage and was devised for the purpose, with the time frame of 24 hours being chosen arbitrarily. The 24-hour limit divides stroke from transient ischemic attack, a related syndrome of stroke symptoms that resolve within 24 hours. With the availability of treatments that can reduce stroke severity when given early, many now prefer alternative terminology, such as brain attack and acute ischemic cerebrovascular syndrome, to reflect the urgency of stroke symptoms and the need to act swiftly. In an ischemic stroke, blood supply to part of the brain is decreased, leading to dysfunction of the brain tissue in that area. There are four reasons why this might happen: Thrombosis Embolism, Systemic hypoperfusion Cerebral venous sinus thrombosis.
A stroke without an obvious explanation is termed cryptogenic. There are various classification systems for acute ischemic stroke; the Oxford Community Stroke Project classification relies on the initial symptoms. These four entities predict the extent of the stroke, the area of the brain, affected, the underlying cause, the prognosis; the TOAST classification is based on clinical symptoms as well as results of further investigations.

William Raymond Dommersen Dommersheusen and Dommersheuzen, was an English painter of Land- and Seascapes and Towns. He signed his work as WR Dommersen. Dommersen was born at the end of 1859 in Stratford, West Ham, London as the son of the Anglo / Dutch fine art painter Pieter Cornelis Dommersen and Anna Petronella Synja, his parents had moved from the Netherlands in 1855 to England. Pre 1700 the family came from Dahlheim, near Koblenz, in Germany, so their family name was originally'Dommershausen', he married c. 1887 Annie Louisa Gormer and had at least four sons and two daughters of whom there are descendants living in England and Scotland. His uncle, Cornelis Christiaan Dommersen, was a painter in the Netherlands, it is possible that when his father received British nationality that they changed their family name – Dommershuizen – into the more English sounding surname Dommersen / Dommerson. Dommersen's grandmother, Cornelia Dommershuizen and his Uncle, Thomas Hendrik Dommershuizen were both portrayed by the famous Anglo/ Dutch painter Sir Lawrence Alma-Tadema in 1862.
Dommersen painted between 1875 and 1927 genre pieces, marine scenes, village- and town-scenes of quality. His best known works are the European towns along rivers and canals, he painted in the Netherlands and England but visited often with his father and uncle, Belgium and Italy. His work such as view on the Canal Grande in Venice, river views in the Thames and Windsor Castle are well known. At some stage he lived in Royal Tunbridge Wells Kent, strategically placed for his travels to Europe. Whilst living in Royal Tunbridge Wells he painted The Pantiles there, he had an only brother, William Daniel Dommerson, born Stratford, London, c. 1860, but died before 1871. William Raymond Dommersen died in 1927 in London.
