Dyslexia is one of the most common learning disabilities and about 4% of people over the world suffer from it. These patients have difficulty in processing language, especially in tasks involving reading and writing. Dyslexia is more common in males as compared to females and it can continue into adulthood also.
Causes of Dyslexia:
Dyslexia is an inherited condition which appears to affect more boys than girls and the genetic component has been found to play an important role in the development of this condition. In dyslexic patients, structural differences in the way the brain is wired up during development stage have been found. There has been found a deficit in a special pathway between the eye and the brain- the "magnocellular pathway&"- in dyslexic individuals. Many people with dyslexia have also found to be deficient in omega-3 unsaturated fatty acids.
