I am curious as to why you claim to be the "most intelligent life form on the planet?" Is it due to your medical condition? Assuming for the moment your statements have been truthful, I'm not seeing a correlation between your brain operating at 100% for even the most menial tasks and intelligence. To use the CPU analogy, operating at 100% would actually be less beneficial and probably even detrimental.
That being said, once again assuming your statements are truthful, I would be curious as to what other tests the doctors have subjected you to? Did they test your noradrenaline, dopamine and serotonin levels?
Based solely on your post I would guess that a condition that you described would probably be the result of the (about go go full nerd on you) vesicles at the end of the presynaptic neurons axon are malfunctioning in that they are completely uninhibited and are secreting neurotransmitters nonstop. The tests mentioned above should have been the very first thing your doctor checked.
