Elwood Blues Has Tourette's?

According to this How Stuff Works article, Dan Ackroyd is one of a handful of famous people afflicted with Tourette Syndrome:

• Mahmoud Abdul-Rauf, former NBA player
• Dan Aykroyd, actor
• Pete Bennett, “Big Brother” reality-show personality
• James Boswell, author
• Brad Cohen, award-winning teacher and author
• Jim Eisenreich, former Major League Baseball player
• Tim Howard, goalkeeper for Manchester United Football Club
• Samuel Johnson, 18th-century author of “A Dictionary of the English Language”
• Mozart, composer (this has been disputed, but it does make for good gossip)
• Michael Wolff, jazz musician

Hmm. Maybe "famous" should be in quotes, particularly when you have a teacher on the list. (Nothing against teachers, but the only "famous" teacher I can think of is the Mr. Holland's Opus guy, whose name escapes me at the moment.)

Interestingly, Wikipedia, that bastion of good research is unsure whether having Ackroyd on that list is accurate or not:

Aykroyd described himself (in a radio interview with Terry Gross) as having mild Tourette syndrome that was successfully treated with therapy when he was a preteen, as well as mild Asperger syndrome. The diagnosis of Asperger syndrome did not exist in the 1960s, when Aykroyd was a preteen. It is unclear if Aykroyd received the diagnoses of TS or AS from a medical source, whether he was speaking in his role as a comic, or whether the diagnoses were self-made. It was an audio interview, so the audience could not see Aykroyd's facial expressions, but the interviewer indicated uncertainty about whether Aykroyd was kidding.

My interest in the subject, besides adding to the already-huge portion of my brain devoted to useless entertainment trivia is that I had a friend with Tourette's in college, a fellow named Robert. I was at a friend's party, when the guy next to me repeatedly rolled his head. "Stiff neck?" I asked, stupidly. No, he told me, without a hint of malice or irritation, he had Tourette's, and went on to explain exactly what that meant.

Of course, pop culture focuses on the sensational elements of the syndrome, specifically the random foul language (coprolalia, which I believe translates literally to "shit language"). And, look, I'm not going to deny that that sort of thing isn't funny, sometimes. Discomfort in social situations is always a rich vein of humor - like when a kid points out someone's fat ass at the mall. But for a disease that's surprisingly prevalent (it's estimated that 1 in 100 have Tourette syndrome, with varying degrees of severity), but only 15% of sufferers have that symptom, and the focus on that one symptom undoubtedly causes some stigma for all the people afflicted with the disease.

Robert described his Tourette's to me thusly: He has these compulsions to do things that he can't ignore. The head-rolling was just one. He had also plucked out a good deal of his eyebrows.

Thing was, as so often happens, the better I got to know the guy, the less I even noticed these his tics. He was just a nice guy to hang out with.

I wonder what happened to him.
