My colleague David Spry is helping people with Parkinson's Disease get symptomatic relief using nutritional therapies. In particular, he is undertaking extremely careful and holistic research on a nutritional-genetic issue, in which people with a specific gene profile are not only very prone to nutritional deficiencies related to “melthylation” and "folates", but also that this makes them highly susceptible to a wide spectrum of food intolerances. David is revealing the role these issues play in the motor and non-motor symptoms associated with PD, and is demonstrating that, by addressing these, significant improvement can be acheived in the condition of people who have developed Parkinsonism’s in this genetic class. Most importantly, David has pioneered this approach by testing out his conclusions on himself.
