What you see above is a glimpse of the debate lecterns used by both Hillary and Clinton. Clearly, the two are different. These were only visible on-air for a short time and we understand that in-person, from the audience, they were almost invisible.
Still, it is obvious that (a) Hillary has a video screen that is being used to "coach her" and Trump does not. Secondly there is something inside Hillary's lectern that appears either mechanical or electronic. What is going on here?
Is it possible that Hillary requires constant IV doses of some kind of stimulant or neural-chemistry enhancer to stay cognizant for the entire debate? Possible.
The screen is less questionable. Small video screens can be made that when "off" appear as a wood-grain to even close inspection. Hillary has used ear-mics in past debates but it is possible that her hearing has degraded to the point of needing to read responses.
There's another possibility: hypnotic conditioning can be used with a willing, suggestible subject to guide them when they are in a trance state. If Hillary has enough higher brain functions shut down--but has been trained to utilize a hypnotic data-feed, she might be able to be effectively programmed to respond to visual stimulus and repeat words or phrases.
If it sounded like some of her answers were entirely disconnected from the questions last night, perhaps that is because they were simply pre-programmed responses she had been conditioned to use. We will note that when the Trump campaign suggested a drug test prior to the debate the Clinton campaign panicked and released their entire catalog of "bimbos" in one gasp.
It is certainly true that Hillary does not want her medical records released--and that she would, similarly, refuse to take a blood test. The custom modifications to Hillary's lectern alone are enough to show that the Presidential Debate Commission is working actively to elect Hillary Clinton and stop Donald Trump.
