The summer before entering sixth grade, Sammy suddenly began to exhibit disturbing behavior. He walked and ate with his eyes shut, refused to bathe, burst into fits of rage, slithered against walls, and used his limbs instead of his hands to touch light switches, doorknobs, and faucets.
Sammy’s mother, Beth, watched helplessly as her middle child descended into madness. Sammy was soon diagnosed with OCD and later with Tourette syndrome. Unwilling to accept the doctors’ prognoses for lifelong mental illness and repeated hospitalizations, Beth fought to uncover what was causing this decline. Racing against time as Sammy slipped further from reality, Beth’s quest took her to the center of the medical community’s raging debate about whether mental illness can be caused by infection. Beth searched until she found two cutting-edge doctors who answered that question with a definitive yes. Together, they CUREDSammy. Five years later, he remains symptom free.
He had strep virus or the antibodies running thru his system. They weren't giving him strep throat but were causing the ocd. He still has to watch his stress levels and stuff, but if there's a flare-up he goes back on the meds until it settles down again.
