Basically, my dad is 52 years old and he has a written text at work for a health and safety check. He is able to communicate verbally, and he is perfectly able to read newspapers and anything. However, he really struggles to put pen to paper and he struggles a lot to spell basic words, such as alarm, or pillow. He says he knows the answers to the test, but he will fail for the simple reason is he wont be able to spell and put the words on the paper. I'm pretty sure he has dyslexia, but is there anyway to help him or is it too late now?
