In 1985, science journalist Jon Palfreman investigated a group of drug addicts who were struck with Parkinson’s-like symptoms after taking tainted heroin. Thirty years later, Palfreman was diagnosed with Parkinson’s disease. In his book Brain Storms, he describes having Parkinson’s as “going on vacation in another country and having to drive on the ‘wrong’ side of the road.” Palfreman describes his own journey with the disease and discusses new treatments for Parkinson’s patients.
