Dyslexia, perhaps the most commonly known learning difficulty, is a language-based learning disability in which a person has trouble reading words, sentences or paragraphs. Both oral and written language are affected.   Studies show that individuals with dyslexia process information in a different area of the brain than non-dyslexics do. Many people who are dyslexic are of average or above average intelligence. Dyslexia is the most common cause of reading, writing and spelling difficulties. Dyslexia affects males and females nearly equally, and people from different ethnic and socio-economic backgrounds equally as well.     Famous People With Learning Difficulties Whoopi Goldberg Steven Spielberg Jack Nicholson Robin Williams Magic Johnson Winston Churchill Leonardo da Vinci Mozart Thomas Edison Albert Einstein Henry Ford Galileo Tom Cruise George Washington
