Dr. Hu, a neurologist and co- investigator at Oxford's Parkinsons Center provides an excellent 26- minute overview in this video highlighting what Oxford is doing to identify 5 different 'types' of Parkinson's, using a more refined scoring system they have developed. Ultimately, more precisely defining a person's PD status would allow for more targeted treatment. It would also help more accurately test potential new PD medications in clinical trials instead of trying to test a medication for all types of PD (this approach seems exasperatingly diffused and prone to failure). In my humble opinion, subcategorizing PD could significantly speed trials. This work could be so important for finding better treatments for PD. Hikoi - thanks for sharing this video. I would love to hear what others think.
