Here is an short summary of the different types of dyslexia.

My DS19 has the phonetic/coding issues type of dyslexia. His misspelled words didn't even have the phonetic awareness and his over writing was disorganized even when spelled correctly. He is MG not HG+. I will say his MG has helped him overcome the disability as well as can be expected.

I know there are at least 3 types but I'm not familiar with the others.

I have heard friends mention caffiene can help with ADHD. I had a doctor ask me about my caffeine intake and if I was self medicating with the coffee ...hmmm I'm still pondering that one.
