  1. Stroke - Wikipedia › wiki › Stroke

    The word stroke was used as a synonym for apoplectic seizure as early as 1599, and is a fairly literal translation of the Greek term. The term apoplectic stroke is an archaic, nonspecific term, for a cerebrovascular accident accompanied by haemorrhage or haemorrhagic stroke.

    From Simple English Wikipedia, the free encyclopedia For other uses, see Stroke (disambiguation). A stroke is an illness in which part of the brain loses its blood supply. This can happen if an artery that feeds blood to the brain gets clogged, or if it tears and leaks.

    In the context of an internal combustion engine, the term stroke has the following related meanings A phase of the engine's cycle, during which the piston travels from top to bottom or vice versa. The type of power cycle used by a piston engine. "Stroke length", the distance travelled by the piston during each cycle. The stroke length––along with bore diameter––determines the engine's displacement.

    Commonly used engine phases/strokes are described below. Other types of engines can have very different phases.

    The thermodynamic cycle used by a piston engine is often described by the number of strokes to complete a cycle. The most common designs for engines are two-stroke and four-stroke. Less common designs include five-stroke engines, six-stroke engines and two-and-four stroke engines.

    The stroke length is how far the piston travels in the cylinder, which is determined by the cranks on the crankshaft.

    CJK strokes are the calligraphic strokes needed to write the Chinese characters in regular script used in East Asian calligraphy. CJK strokes are the classified set of line patterns that may be arranged and combined to form Chinese characters in use in China, Japan, and Korea.

    The study and classification of CJK strokes is used for

    When writing Han radicals, a single stroke includes all the motions necessary to produce a given part of a character before lifting the writing instrument from the writing surface; thus, a single stroke may have abrupt changes in direction within the line. For example: 1. is classified as a basic stroke because it is a single stroke that forms a line moving in one direction. 2. is classified as a compound stroke because it is a single stroke that forms a line that includes one or more abrupt cha

    All strokes have direction. They are unidirectional and start from one entry point. As such, they are usually not written in the reverse direction by native users. Here are some examples: 1. 2. 3. 4. 5. 6.

    CJK strokes are an attempt to identify and classify all single-stroke components that can be used to write Han radicals. There are some thirty distinct types of strokes recognized in Chinese characters, some of which are compound strokes made from basic strokes. The compound strokes comprise more than one movement of the writing instrument, and many of these have no agreed-upon name.

    Organization systems used to describe and differentiate strokes may include the use of roman letters, Chinese characters, numbers, or a combination of these devices. Two methods of organizing CJK strokes are by: Classification schemes that describe strokes by a naming convention or by conformity to a taxonomy; and Categorization schemes that differentiate strokes by numeric or topical grouping. In classification schemes, stroke forms are described, assigned a representative character or letterfo

    Japanese stroke order: Prescribed mostly in modern Japan. The standard character set of the MEXT is the Jōyō kanji, which contains many characters reformed in 1946. The MEXT lets editors freely prescribe a character's stroke order, which all should "follow commonsensical orders which are widely accepted in the society" [citation needed].

    Perinatal stroke is a disease where an infant has a stroke between the 140th day of the gestation period and the 28th postpartum day, affecting up to 1 in 2300 live births. This disease is further divided into three subgroups, namely neonatal arterial ischemic stroke, neonatal cerebral sinovenous ischemic stroke, and presumed perinatal stroke. Several risk factors contribute to perinatal stroke including birth trauma, placental abruption, infections, and the mother's health. Detection and diagno

    A neonatal arterial ischemic stroke occurs when the blood vessels of the brain are partly or completely blocked. This situation normally affects the middle cerebral arterial region. This subgroup of perinatal stroke affects between 5 to 43 babies in 100,000 live births. A recent

    Neonatal cerebral sinovenous ischemic stroke is a disease in the cerebral venous system caused by thrombosis. Thrombosis in this region will hinder outflow from the venous system, causing a surge in the central venous pressure. This will lead to intracranial hypertension, cerebra

    Presumed perinatal stroke is a condition when the stroke is only diagnosed after the neonatal period and does not have any significance in neurological examination within the 28 days after birth. The majority of infants who were later diagnosed with PPS were free of symptoms duri

    Perinatal stroke is correlated with various risk factors in infants including birth trauma, placental disorders, infections, and the mother’s health. Birth trauma and mechanical trauma to the fetal head and neck can cause stroke by damaging arteries: Some children may have arteries that are damaged by trauma or inflammation leaving a rough or jagged inner lining where blood clots can get stuck. These clots can build up enough so that eventually the artery is clogged and no blood can flow ...

    Many infants are asymptomatic until they are older. Symptoms such as speech delays, balance difficulties, and asymmetrical weakness become more apparent and are signs that they experienced a stroke. In asymmetrical weakness, infants favor one hand over the other due to cerebral palsy which arises from lesions to the central nervous system. Infants who do give indications of stroke in the womb or shortly after birth commonly experience seizures. When an infant has a seizure, they experience jerki

    Doctors can use diagnostic tests to determine if an infant is having a stroke. After a clinical presentation of a stroke, the first diagnostic tests used are imaging techniques. Further diagnostic tests such as EEG, Echo, blood tests, and genetic tests are carried out depending on the symptoms portrayed by the newborn.

    Perinatal stroke’s severity determines its prognosis. 61% of infants who experienced a perinatal stroke are also diagnosed with cerebral palsy. While, infants with greater stroke severities and involvement of structures such as the precentral gyrus and Wernicke’s area have a critical prognosis. Infants who survived a perinatal stroke may develop disabilities like cerebral palsy, sensory dysfunctions, ADHD, and visual or hearing difficulties. As the prognosis is correlated with the ...

    Stroke, förr vanligen slaganfall, är ett sjukdomstillstånd där syrebrist i en del av hjärnan leder till celldöd i det drabbade området. Stroke innefattar hjärninfarkt (blodpropp i hjärnan) och hjärnblödning, vilka båda leder till skador i hjärnan.
