Interesting! I’ll give it a try. Thanks.
There is a research Neurologist named Harlold Levinson who was one of the first persons to link what many were seeing as ADD ADHD to actually being Vestibular patients because many shared the same history of either allergies or chronic ear infections etc early in their childhood.
The trick seems to be finding which chemical works which which portion that has the damage and that is where caution must be used. I can drink 6-8 20 ounce cokes a day with no problem. Caffeine has absolutely not effect on me. I can hear a phone ring, go too a crowded Walmart, or even see certain TV shows where they use intense special effects like flashing and it sets me off.
BTW this also really does not limit ones intelligence as such, but rather the brain simply adapts too a different way of learning. I can't sit and read a book but I can sit and answer well over 50% of answers in game shows involving history, geography, and even science. I can't grasp things like Algebra but I can in my head take $300 to the store too buy groceries and come out within $10-$20 of the $300.
This might help some understand it. Cognitive Aspects of Vestibular Disorders This is just one of many disorders that can be mistaken as ADD ADHD as well as adult Anxiety Disorder which has also had an increase in the past few decades. Most Shrinks do not consider what this link says. Yet problems related too your Vestibular System {any hearing or balance issues} can trigger major behavioral issues from lack of energy, lack of concentration, agitation, anxiety, depression, and some case hyperactivity as this also in some situations triggers adrenalin release as well.
