Let there be light! Well, certain types of light, at least. That's what we're discussing down at the Movers and Shakers Arms today, where the gang are joined by Professor Glen Jeffery, an expert in the use of light therapies. Why are some lights – like infrared – good for us, whilst others – like UV – are bad? How does light impact on our mitochondria? And, most importantly, what does any of this have to do with Parkinson's?! Join us for a fascinating dive into a less-discussed, but possibly very important, piece in the puzzle of searching for a PD disease modifier.
