Did You Know… #55

In recent years, discoveries have found that OCD symptoms can be caused by strep C throat infections. When children with strep throat became compulsive hand-washers, MRI scans showed their caudates had swollen 24%. The caudate is the part of the brain that allows our thoughts to flow. When given immune-suppressants, the childrens’ symptoms eased and those who had the most swelling of the caudate had the worse symptoms, thus showing a causal relationship between caudate size and OCD behaviour.
