Dr Catherine Hamilton
Catherine was a happily retired medical practitioner when in 2015, the threat of a knee replacement caused her to discover photobiomodulation and the work of University of Sydney’s Prof John Mitrofanis. She made a light device for her knee, and light hats for people with Parkinson’s disease, all with surprisingly good outcomes. In 2018 she and electronics engineer Ron Brown developed the transcranial red and near infrared light device called the Coronet, now used by people with Parkinson’s all over the world and in clinical research. Catherine has published case reports describing the consistent finding that daily transcranial red and near infrared lights improve both non-motor symptoms and motor signs. The change in previously untreatable non-motor symptoms is one of the major benefits both to patient and carer quality of life.
Catherine is a director of Well Red Pty Ltd, she lives in a rustic environment where she grows veggies, makes jam and preserves fruit. She conducts and accompanies a community choir with a median age of 74, and is the author of the blog redlightsonthebrain which provides DIY instructions for making a light hat device as well as regular updates from the research literature. Catherine is an Honorary Associate, University of Sydney.
