A systematic review and meta-analysis explored peripheral biomarkers for Tourette syndrome (TS). Overall, 60 studies were analyzed. The study identified several biomarkers associated with TS, suggesting their potential for early diagnosis. Suggestive associations were evidenced for norsalsolinol (NSAL), neuron-specific enolase (NSE), and S100B. However, larger and more standardized studies are needed to validate these findings for clinical use.

New research reveals that non-ablative radiotherapy suppresses ventricular tachycardia by increasing conduction velocity via NaV1.5 upregulation and action potential prolongation. However, sustained sodium current elevation and depressed calcium handling highlight the need for careful clinical translation.
