There has been a study in Australia and Canada hospitals using red light therapy to help patients with symptoms of Parkinson's. From what I have seen the study showed improvement with many symptoms from constipation, brain fog, ambulation and tremors along with depression and more. If you look on you tube and look for red light therapy or photobiomodulation you can see. Of course everyone is different.

The only red light therapy I ever had was back in traffic court

Will definitely check out red light therapy!!!! Thanks!!! Welcome to parky world where we fight the good fight!!!

The only red light therapy I ever had was in a dream !
