Parkinson’s disease

Lead: Professor Michele Hu

Parkinson’s disease (PD), like many brain disorders, start many years before symptoms become apparent to patients and their doctors. Our research has shown that people with REM sleep behaviour disorder (RBD) often go on to develop Parkinson’s more than a decade later.

People with RBD enact their dreams, with often violent physical movements, talking and shouting. Typically, they may also lose their sense of smell or experience mood and other changes many years before showing the classic symptoms of Parkinson’s.

If we can detect these warning signs at an early stage, we can diagnose Parkinson’s much earlier and improve the quality of life for patients and their loved ones.

Our work is strongly rooted in the Oxford Parkinson’s Disease Centre (OPDC) Discovery Cohort, which comprises 1,600 participants from the Thames Valley region followed up since 2010. Local Parkinson’s UK support groups have worked with us to shape the research and given us vital advice on reaching all Parkinson’s patients, including those who are especially hard to reach.

Our RBD patient cohort gives an important window into earlier or prodromal Parkinson’s, where motor symptoms such as tremor have not yet developed. By following their progression, we can test new biomarkers – for example brain imaging, blood tests and digital methods such as smartphone apps or wearable accelerometers – that might predict future PD progression. Ultimately, this will allow us to develop a simple test that can be applied at a wider population level through general practice.

We know that certain abnormal proteins in the cerebrospinal fluid, such as alpha-synuclein, are biomarkers for PD. Other ‘misfolded’ proteins can be an early warning sign for other conditions, such as motor neurone disease, Alzheimer’s and other forms of dementia.

Using a technique called real-time quaking-induced conversion, we can aggregate or amplify the proteins in a spinal fluid sample. This promises to be a useful early diagnostic test which will allow us to stratify our patients and identify those at highest risk of progression to PD.

Working with the BRC’s Translational Data Science Theme, we are following around 1,000 patients with early PD from our Discovery Cohort over a 15-year longitudinal study to develop a prognostic index to predict who will develop severe disease earlier. The aim is to tell a patient at diagnosis when they are likely to develop typical PD symptoms and individually predict how things might change or progress over the next 10 years that they live with PD

Following similar studies with our RBD sleep group, we are using data from participants in the UK Biobank who are wearing wrist accelerometers for a week. Data from those participants who go on to develop PD will be invaluable in developing a model for the earlier diagnosis of the disease.

We are developing and simple tests that can be carried out on a smartphone which can help to predict future change in people in the early stages of PD, and so determine the support they may need. We are also using web-based testing that can diagnose or predict cognitive decline in our patients, as well as home-based sleep testing to diagnose early PD.

Our theme is also involved in a number of drug trials, including a phase 3 clinical trial looking at whether the diabetes treatment exenatide can slow the progression of PD, and whether ketone supplements – chemicals produced in the liver – can increase the ability of PD patients to exercise, which in turn can slow the progression of the disease.
