Appears to be related to the consumption of substances like adrenochrome directly from the brain.
Pretty sure adenochrome is produced in the adrenal glands. It would also be released into the bloodstream. Not positive, but probable that adrenaline products don’t cross the blood brain barrier. Organic chem is not one of my skill sets.
Unsure of the time needed for breakdown. Any MDs/phamacists who can enlighten on this? Pretty sure adrenochrome is short-lived.
Also, to transmit kuru, I would think the prion needed to be already present in the tissue. Infants-—teens might not be old enough to have picked up sufficient prion, if any. The prion lives in soil, so it would be necessary for the child to have lived in an area with prion infection.
Whatever Hillary has, it is most likely to arise from internal chemical imbalances from whatever causes.

Synthetic adrenochrome is available and not regulated.
Regarding Hillary laughing - did you see the story about Alexa? The device is coming out with an unexpected laugh at odd hours - without being given a command/question. That laugh sounds exactly like HRC laugh. Creepy.
