This is an interesting article for anyone interested in dyslexia. I came across this problem with a child last year – he kept complaining that the first letter of the first word in a sentence attached itself to the beginning of every other word, making it impossible for him to read and understand the rest of the text.
I wondered at the time whether it might be dyslexia, even though I had never heard of those symptoms before. I spoke to the school, who spoke to his mom, who got it checked out. For him it turned out to be a hypersensitivity to the flickering of the overhead lights, and coloured glasses to cut down the flicker solved the problem.
It was interesting to read this article recently though, which suggests that it is a type of dyslexia.
