    STEP THREE OF TOXIC CASCADE INFLAMMATION IS LOWER IN PD PATIENTS Data from first 14 PD patients 18 The trial measured four inflammatory markers that are prevalent in the brains of AD and of PD patients. Each of the inflammatory markers showed statistically significant reduction after 25 days of trea
