New research into swallowing problems in Parkinson's

16 February 2010

We have awarded an innovation grant of nearly £16,000 for research investigating why people with Parkinson's have trouble swallowing.

Swallowing problems in Parkinson's are a major clinical challenge, and one which often gets little attention in medical research.

The grant has been awarded to Dr Shaheen Hamdy from the University of Manchester.

As Parkinson's develops, many people find that everyday activities like swallowing become more difficult due to changes in how throat muscles work.

Difficulties in swallowing can lead to serious complications, from problems with breathing, to not getting enough nutrition and developing pneumonia.

A new way of stimulating the brain

Little research has taken place into why swallowing is affected in Parkinson's. But we know that drugs like levodopa, which is used to treat the symptoms of the condition, don't seem to help.

Dr Hamdy has been researching how a new way of stimulating the brain, called 'transcranial magnetic stimulation' (TMS), affects swallowing.

By turning on a magnetic field above a particular part of the brain that helps control movement, it's possible to make specific throat muscles respond.

What the researchers will do

We hope that this research will help increase understanding of swallowing problems, which will lead to better treatment options.

Dr Kieran Breen, Director of Research

40 people with Parkinson's will take part in the research over 2 days, both on and off medication.

Using TMS, researchers will measure how active the muscles that control swallowing are by recording the throat responses to a series of magnetic brain pulses.

The study will also look at how areas of the brain that control swallowing are affected by Parkinson's drugs.

Dr Hamdy comments:

"Swallowing problems in Parkinson's are a major clinical challenge, and one which often gets little attention in medical research.

"We are delighted that the Parkinson's Disease Society has decided to fund our research."

Funding cutting edge research

Dr Kieran Breen, our Director of Research and Development, adds:

"We hope that this research will help increase awareness and understanding of swallowing problems in people with Parkinson's, which will lead to better treatment options.

"This is only a small study, but it could give us enough information to know whether TMS is a new treatment worth pursuing.

"We are passionate about funding cutting edge research to find a cure and better treatments, which is what our innovation grant programme is all about."
