Some of the common “symptoms” of Parkinson’s Disease could be reframed as behavioural patterns contributing to overall symptomology, but which can be ameliorated through appropriate retraining to help with progressive symptom reduction. Examples of such retrainable “habits” include issues with posture, mindset and breathing. These patterns tend to impact each other, for example habitual mouth breathing can result in the forward head position common in PD. People with PD will often see in hindsight that, once identified, these problematic habits were apparent years before diagnosis. In this article, we specifically consider how unhealthy, but fixable, breathing patterns could be an exacerbating factor in PD. We will cover how poor breathing interacts with, and may even be causal of, many other symptoms, and explore what we can do to improve our quality of life by taking action to retrain our breath.
