Actually, syndrome is NOT an illness! From Dictionary.com
Pathology, Psychiatry. a group of symptoms that together are characteristic of a specific disorder, disease, or the like.
2. a group of related or coincident things, events, actions, etc.
3. the pattern of symptoms that characterize or indicate a particular social condition.
4. a predictable, characteristic pattern of behavior, action, etc., that tends to occur under certain circumstances: the retirement syndrome of endless golf and bridge games; the feast-or-famine syndrome of big business.
Frankly, I disagree with the first one. The others merely indicate some range of symptoms(GOOD OR BAD) that make up a common pattern, and the syndrome gives the pattern a name!
HECK, I just don't like garbage like what your friend said. As for dyslexia, it is some kind of confusion that is either due to reversed wiring of a sort, or incomplete associations. Either way, it CAN be compensated for and "get better". Heck, most believe that is what AS is. Improper remapping, so people still lose some social stuff, but gain elsewhere.
