Graduate Student

Neurometabolism and Parkinson's disease

Nicholas Norwitz completed his PhD, "Exogenous ketones as a metabolic intervention for Parkinson's disease," under the supervision of Professor Kieran Clarke. This project emphasized human clinical trials aimed at exploring the medical applications of the ketone bodies, D-β-hydroxybutyrate, in patients with Parkinson’s disease. Nick's early data demonstrate that exogenous ketone supplementation can improve some aspects of motor function in Parkinson's disease. Furthermore, Nick and Professor Clarke hypothesize that, by acting as both an efficient fuel substrate for the brain and as a signaling molecule, D-β-hydroxybutyrate may slow the progression of Parkinson’s disease.
