Artificial intelligence (AI) is being applied by scientists to all aspects of Parkinson’s research. From drug discovery to protein folding, the power of these supercomputers is being utilized and it is starting to bear interesting pieces of fruit.
Recently a group of scientists in Toronto (Canada) have reported a study using AI to identify clinically available drugs that may reduce the risk of developing Parkinson’s (or slow it onset).
Specifically, using IBM’s Watson super computer, they screened through a medical records database (the Ontario Drug Benefit), and identified several classes of drugs that reduced the risk of developing PD.
In today’s post, we will review the results of the recent report and consider the implications.

This week we received fantastic news from the coordinators of the UK RECOVERY Trial that they have identified an agent that appears to have a significant impact on improving survival for individuals affected by COVID19 infections.
The RECOVERY (Randomised Evaluation of COVid-19 thERapY) trial – launched across 175 NHS hospitals in the UK in March – is one of the world’s largest randomized, controlled trials for coronavirus treatments (Click here to read more about this details of the trial). The study currently has more than 11,000 patients enrolled and it is evaluating 6 agents for their ability to combat the COVID-19 virus, SARS-CoV-2.
This week the researchers conducting the study announced that the corticosteroid dexamethasone – a medicine that reduces inflammation by mimicking anti-inflammatory hormones produced by the body – was able to reduced the risk of dying in infected individuals (on receiving oxygen therapy but were not on ventilators) by 20%. The agent had no effect on people with less severe cases of COVID-19.
It is a remarkable achievement – involving 2,100 patients who received the drug at a low-to-moderate dose of 6 milligrams per day for 10 days and were compared against approximately 4,000 patients who received standard care for the coronavirus infection (UPDATE 22/6/2020: a manuscript of the result is now avaiable – click here to read it).
Yeah, it’s brilliant. But what does this have to do with Parkinson’s?
Well, very recently dexamethasone has been identified as potentially having an effect on another medical condition.
Care to take a wild guess as to which condition that might be?
Here at the SoPD, we are primarily interested in disease modification for Parkinson’s. While there is a great deal of interesting research exploring the causes of the condition, novel symptomatic therapies, and other aspects of Parkinson’s, my focus is generally on the science seeking to slow, stop or reverse the condition.
At the start of each year, it is a useful practise to layout what is planned and what we will be looking for over the next 12 months. Obviously, where 2020 will actually end is unpredictable, but an outline of what is scheduled over the next year will hopefully provide us with a useful resource for better managing expectations.
In this post, I will try to lay out some of what 2020 holds for us with regards to clinical research focused on disease modification for Parkinson’s.

My old scout master once looked around our horse shoe, making eye contact with each of us, before asking the question:
“When did Noah build the ark?”
My fellow scouts and I looked at each other – confused. Did he want an exact date?!?
The scout master waited a moment for one of us to offer up some idiotic attempt at an answer – thankfully no one did – before he solemnly said:
“Before the rain”
It was one of those childhood moments that made little sense at the time, but comes back to haunt you as an adult when you are looking at what the future may hold and trying to plan for it.

Today’s post is our annual horizon scanning effort, where we lay out what is on the cards for the next 12 months with regards to clinical research focused on disease modification in Parkinson’s.
We will also briefly mention other bits and pieces of preclinical work that we are keeping an eye on for any news of development.
To be clear, this post is NOT intended to be an exercise in the reading of tea leaves – no predictions will be made here. Nor is this a definitive or exhaustive guide of what the next year holds for disease modification research (if you see anything important that I have missed – please contact me). And it should certainly not be assumed that any of the treatments mentioned below are going to be silver bullets or magical elixirs that are going to “cure” the condition.
In the introduction to last year’s outlook, I wrote of the dangers of having expectations (Click here to read that post). I am not going to repeat that intro here, but that the same message applies as we look ahead to what 2020 holds.
In fact, it probably applies even more for 2020, than it did for 2019.
2020 is going to be a busy year for Parkinson’s research, and I am genuinely concerned that posts like this are only going to raise expectations. My hope is that a better understanding of where things currently are and what is scheduled for the next 12 months will help in better managing those expectations. Please understand that there is still a long way to go for all of these experimental therapies.
All of that said, let’s begin:
