I'm regularly asked if it is possible to track any changes when starting to wear a light hat.

This medical journal article should have been posted ages ago. My apologies for being so slow in making it available to you.

A friend has introduced me to the Joe O'Loughlin series by author Michael Robotham. Joe, a psychologist, is introduced in the first of the series, The Suspect; he lives in and works in London, has a gorgeous wife and daughter and a larger-than-life surgeon father nicknamed 'God's physician-in waiting'.

For over three years now, I've been observing the effect of daily use of red/near infrared light hat devices on people with Parkinson's disease. I continue to be astonished at the way red/near infrared lights can improve the non-motor or non-movement symptoms - especially apathy. I think apathy is probably one of the most cruel of the many Parkinson's symptoms.
