Yale’s proof-of-concept study involved 10 patients who had been diagnosed for less than four years and hadn’t lost all their dopamine-producing neurons.
They received MRI and PET scans to measure the amount of neuromelanin found in dopamine-producing neurons and the protein dopamine transporter (DAT) which helps the neurons maintain dopamine levels.
After six months of HIIT three times a week, the scans were repeated and the brain imaging showed a significant increase in both the neuromelanin and DAT signals. Researchers say this suggests HIIT not only slowed down the neurodegenerative process, but that it also helped the dopaminergic system grow healthier.
“Where we would have expected to see a decline in the DAT and neuromelanin signals, we saw an increase,” says Professor Bart de Laat, the study’s first author. “We had hoped to see that the neurodegeneration wouldn’t progress as quickly or that it would stop temporarily, but instead we saw an increase in nine out of 10 people. That was remarkable.”
Are you absolutely sure it was HIIT? I went back to the original Yale article and it does not mention that at all… It just says high intensity. Here is the link: medicine.yale.edu/lab/tinaz...
in the article, they mentioned this particular website that they got the exercises from:
I emailed them to ask what specific exercise the participants used. I hope they reply. When reading the information on the website, it seems like it was “based on“ HIFT training but it’s really quite vague.
Did you see any information either corroborating or contradicting the information I’ve written here? I’d be very curious to find out…
a word of caution. I’m over 70 and was not accustomed to heavy exercise. I tried HIIT and immediately was injured with sciatica. Hard to heal from that. A real setback. Younger folks with excellent tone and perfect diets might be able to jump right in. But older folks might need to begin very gradually. 😅
I have contacted Beat Parkisons which is the program they used at Yale as I don't have access to the program in California. Here is their response:

Call or email me, Emily, with any questions!
We are so excited for you to join us and start feeling the benefits of our specialized exercise program for people with Parkinson’s Disease.
Very interesting concept. May definitely be something here. If it is in truth HIIT. A significant but subtle omission is not a healthy sign. Ask any attorney, lie of omission is still a lie. In both science and law, leaving something incomplete sometimes is the result of an affirmative effort to "leave" it out, because of the rigor and completely discipline that is pounded into people trained in science and law (and also big business), it's not really to be assumed an "error" of omission. That's why if somebody lies on the stand, if they lie once they are considered to be liable to lie all the time. So that link has to be filled in at some point. It's also a key element of the era we are in that such omission is a very valued and successful strategic step in business and liability matters. Just saying. The concept is very intriguing for sure though.
