Researchers found that low doses of Tacrine hydrochloride reduced motor and vocal tics in adults with Tourette syndrome. The study also showed dose-related improvement in comorbid symptoms such as attentional difficulties, hyperactivity, and obsessive thinking.
Researchers at Johns Hopkins Medicine have discovered that brain antibodies may trigger Tourette's syndrome in part by attacking brain nerve cells after a bacterial infection. The study found higher levels of antibodies against proteins in the putamen area of the brain, suggesting a link between infections and Tourette's symptoms.
Researchers found that identical twins with differing tic severities had higher binding to D2 dopamine receptors in the caudate nucleus. This finding suggests that environmental influences modify Tourette Syndrome expression, contrary to previous studies suggesting a fixed genetic component.
