Dyslexia is an inherited condition that makes it extremely difficult to read, write, and spell in your native language, despite having an at least average intelligence. Dyslexia is very common, but has only been talked about in recent years. It was 1878 when German neurologist, Adolph Kussmaul, first used the phrase “word blindness” describing what we know as dyslexia today. The word dyslexia was first used by Rudolf Berlin of Stuttgart, Germany, in 1887 to describe the inability to read. In 1905 W.E. Burner published the first report of childhood reading difficulties in the U.S.. It was not until 1925 that an American neurologist Dr. Samuel T.

Most people that have dyslexia have it because it is passed on genetically. So if one of your parents has dyslexia you have a fifty percent chance of having it as well. But if both of your parents have dyslexia them you will most likely have it as well. Dyslexia does not affect any certain ethnic group, but most people know only white people that have dyslexia instead of someone of another race. Doctors run many tests to diagnose dyslexia. They first check your background to see if it runs in your family. Then they test your oral language skills to see your ability to listen to and understand speech as well as to express our thoughts through speech. The doctor 's also check a multitude of other things such as word recognition which is the ability to read single printed words. Decoding which is the ability to read unfamiliar words by using letter-sound knowledge, spelling patterns and chunking the word into smaller parts, such as syllables. Spelling which measures the student’s ability to spell individual words from memory. Phonological processing which is the ability to decode or sound out words. Automaticity and fluency skills which test a person 's naming speed. Reading comprehension typically, students with dyslexia score lower on tests of reading comprehension than on listening comprehension because they have difficulty with decoding and accurately or fluently reading words. Vocabulary knowledge which is one of the most important skills to test because vocabulary greatly affects understanding when listening or reading. The most common and really only cause of dyslexia is that it is passed on
