Multiple N-of-1 Trials of (Intermittent) Hypoxia Therapy in Parkinson's Disease

Summary

In recent years, mitochondrial dysfunction and oxidative stress have been implicated in PD pathophysiology. Intermittent hypoxia therapy (IHT) is an upcoming treatment used by elite athletes as well as fragile individuals in clinical settings that works by improving exercise tolerance, neuroplasticity and inducing hypoxic preconditioning (HPC). HPC might improve the oxidative stress response in PD on the long-term. In addition, preclinical evidence suggests beneficial short-term effects such as influence on dopamine and noradrenalin release. Anecdotal evidence indeed suggests that visiting high-altitude areas improves PD symptoms and it is hypothesized that this effect results from decreased oxygen pressure at high altitudes. The safety and feasibility of (intermittent) hypoxia therapy on PD symptoms will be assessed in an exploratory phase I randomized-controlled trial.
