People have often wondered what causes dyslexia.  Now, researches at Northwestern may have determined.

According to lead author of the study Nina Kraus, Hugh Knowles Professor of Neurobiology, Physiology and Communication at Northwestern, the biological underpinnings all revolve around the brain and a seemingly unrelated action – a person’s hearing ability.

According to Time magazine "The researchers, who reported their findings in the Journal of Neuroscience, recorded the automatic brain wave responses of 100 kids aged six to 13 as they heard speech sounds. The brains of the more adept readers encoded the sounds, or processed the speech into brain waves, in a more consistent way than those who struggled to read. The latter group tended to show more erratic and fluctuating patterns, which understandably meant that their brains were less able to consistently connect sounds with words. That in turn could interfere with their ability to read, since reading in part involves a virtual hearing of printed language. “Understanding the biological mechanisms of reading puts us in a better position to both understand how normal reading works and to ameliorate it where it goes awry,” study author Nina Kraus, a professor of neurobiology, physiology and communication at Northwestern University said in a statement."

According to the blog Additude, there is a new documentary that shows how kids with learning differences, if given the right resources, can be very successful.

"I Can’t Do This But I Can Do That introduces us to five children who are mislabeled as slow or lazy. These resilient children and their families, who speak plainly and evocatively about their learning differences, get the right help, tap into their strengths, and leave their challenges behind. "
Dyslexia is something that usually impacts reading, writing and spelling.  But what about Math?  There is something called Dyscalculia which does impact ones ability to do math.  According to wikipedia, there are a number of symptoms, but some of the key ones are:
  • Frequent difficulties with arithmetic
  • Difficulty with everyday tasks like reading analog clocks
  • Inability to comprehend financial planning or budgeting, sometimes even at a basic level; for example, estimating the cost of the items in a shopping basket or balancing a checkbook
  • Difficulty with multiplication-tables, and subtraction-tables, addition tables, division tables, mental arithmetic, etc.
  • Difficulty with conceptualizing time and judging the passing of time. May be chronically late or early
  • Problems with differentiating between left and right
