Dr James Greenblatt, a Boston-area psychiatrist, treated a teenager with severe obsessive–compulsive disorder (OCD), as well as attention deficit hyperactivity disorder (ADHD) and an array of digestive problems.
Greenblatt first did a simple urine test for the metabolite HPHPA and found that it was elevated.
He put the patient, Mary, on a course of high-powered probiotics to boost her good bacteria, followed by antibiotics, and her levels began to ‘dramatically’ go down, he told ABC News.
After six months, Mary's symptoms began to disappear. And by a year, they were gone.
Today, three years later, Mary is a senior in high school and has no sign of either mental disorder.
