Some research has pointed to increased letter-spacing being beneficial.There is currently no evidence showing that music education significantly improves the reading skills of adolescents with dyslexia. Prognosis
Dyslexic children require special instruction for word analysis and spelling from an early age. The prognosis, generally speaking, is positive for individuals who are identified in childhood and receive support from friends and family. The New York educational system (NYED) indicates "a daily uninterrupted 90-minute block of instruction in reading" and "instruction in phonemic awareness, phonics, vocabulary development, reading fluency" so as to improve the individuals reading ability. Epidemiology
The prevalence of dyslexia is unknown, but it has been estimated to be as low as 5% and as high as 17% of the population. Dyslexia is diagnosed more often in males.There are different definitions of dyslexia used throughout the world. Further, differences in writing systems may affect development of written language ability due to the interplay between auditory and written representations of phonemes. Dyslexia is not limited to difficulty in converting letters to sounds, and Chinese people with dyslexia may have difficulty converting Chinese characters into their meanings. The Chinese vocabulary uses logographic, monographic, non-alphabet writing where one character can represent an individual phoneme.The phonological-processing hypothesis attempts to explain why dyslexia occurs in a wide variety of languages. Furthermore, the relationship between phonological capacity and reading appears to be influenced by orthography. History
Dyslexia was clinically described by Oswald Berkhan in 1881, but the term dyslexia was coined in 1883 by Rudolf Berlin, an ophthalmologist in Stuttgart.
Other complications include inflammation of the pancreas. Signs and symptoms
Pain is the most common presenting symptom. It is usually described as sharp, crampy, dull or severe right upper quadrant pain, which may  radiate to the right shoulder, or less commonly, behind the breastbone. Nausea and vomiting can be associated with biliary colic. Individuals may also present with pain that is induced following a fatty meal and the symptom of indigestion. The pain often lasts longer than 30 minutes, up to a few hours. Patients usually have normal vital signs with biliary colic, whereas patients with cholecystitis are usually febrile and more ill appearing. Lab studies that should be ordered include a complete blood count, liver function tests and lipase. In biliary colic, lab findings are usually within normal limits. Alanine aminotransferase and aspartate transaminase are usually suggestive of liver disease whereas elevation of bilirubin and alkaline phosphatase suggests common bile duct obstruction. Pancreatitis should be considered if the lipase value is elevated; gallstone disease is the major cause of pancreatitis. Complications
The presence of gallstones can lead to inflammation of the gallbladder (cholecystitis) or the biliary tree (cholangitis) or acute inflammation of the pancreas (pancreatitis).
