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.Phase:

Criteria
Inclusion criteria:- Informed consent
- Clinical diagnosis of Parkinson's disease by a movement disorder specialized
neurologist with Hoehn and Yahr staging 1.5 to 3.
- 15 individuals with self-reported personal experience of positive altitude effect.
- 5 individuals without self-reported personal experience of positive altitude effect.
Exclusion criteria:
- Individuals with diseases leading to restrictive and obstructive pulmonary diseases,
pulmonary diffusion deficits, apnea and cardiac output deficits, such as pulmonary
fibrosis, COPD, sleep apnea or excessive alcoholic intake, and congestive heart
failure respectively.
- Arterial blood gas abnormalities at screening day (as per normal limits)
- Individuals with shortness of breath or other airway or breathing-related
inconvenience related to lack of dopaminergic medication will be excluded.
- Inability to comply to intervention in off-medication condition (for example due to
extreme discomfort, distress or severe head tremor due to being OFF, i.e. without
dopaminergic medication).
- Individuals with unstable dopaminergic medication dose (changes in the last month)
- Individuals likely to start dopaminergic treatment in the next month, also judged by
their treating neurologist
- Individuals with active deep brain stimulation
- Individuals unable to provide informed consent.
