TS and ADHD, Page 16

[Someone who apparently read my article “Is Tourette’s Syndrome a Neurological Disorder?— A Dissenting Viewpoint” emailed me to further inquire as to why I deny that Tourette’s Syndrome has a physical cause. I answered this person and asked if I could have permission to post his or her email on my website along with my response. Since I received no reply, I cannot post it. However, I see no reason why I cannot post my response as it in no way identifies the person, and I have removed the only brief mention I had made to something personal indicated within the sender’s email. I have decided to post it under TS/ADHD as a stand alone essay rather than under Comments since I am omitting the comment per se. The reply has been otherwise edited]

If one ties a smoker's hands behind his or her back, then that person will cease smoking as long as the encumbrance prevails. Thus, we deduce that one's hands are the cause for one's impulse to smoke, and, in corollary, we can conclude that a piece of rope is the "cure."

That sort of absurd reasoning is precisely, in my opinion, the "logic" which prevails today in regard to TS. Brain scans of people with TS might indeed indicate an unusually high level of dopamine (for example) which, especially in light of its role in regard to motor activity, might well be the direct chemical agency that causes tics. Therefore, "antipsychotic" drugs such as Holdol inhibit its reception within the brain and mitigate the symptoms of TS. It does not necessarily follow, however, per my above analogy, that the patient has any physical, neurological abnormality that periodically and arbitrarily produces an excess of the hormone or increases the brain's sensitivity to it upon reception.

If a blood test were taken of a person in a state of rage, the result would indicate an elevated level of the hormone adrenaline. Does that indicate that the person has such an elevated level because there is some abnormality within his or her adrenal glands? Does this mean that the person is angry because he or she has an elevated level of adrenaline, or does it indicate that the person has an elevated level of the hormone because he or she is angry?

Virtually no one would answer the former. Why then does one presuppose that because a TS sufferer's brain scan indicates an elevated level of dopamine (or other suggested causative hormones) that such is the cause of TS rather than its effect? Click to continue:
