Young-onset Parkinson’s Disease

Debate between David Mowat and Madeleine Moon

Monday 6th March 2017 Commons Chamber

[The Parliamentary Under-Secretary of State for Health (David Mowat)]

Let me start by congratulating the hon. Member for Torfaen (Nick Thomas-Symonds) on his speech, which the former Minister, my hon. Friend the Member for North Swindon (Justin Tomlinson), called an important one. It is just that, as this is an important subject. It is salutary to think that it is 200 years since this terrible disease was first discovered and we are still some way off finding a cure for it. I know that over the past year or so the hon. Gentleman has asked many questions in Parliament, both written and oral, on this subject. I congratulate him on doing that, because it is only by people doing that that we will continue to keep awareness high.

I also thank the hon. Member for Bridgend (Mrs Moon) for the work she does on the all-party group and for demonstrating the kinetic watch. I had not seen one before this evening, but I look forward to seeing it perhaps after this sitting.

[Mrs Moon]

I met people from Global Kinetic on Friday, when they gave me the watch. In September or October, this watch will also have a docking station, which will mean that on a daily basis the consultant neurologist will be able to get a pattern of sleep, movement and medication consumption from a patient. We hope that will cut the need for neurologist appointments, as is happening in some areas, and I hope that the Minister will want to meet Global Kinetics.

[David Mowat]

Indeed. I am sure other brands are available—

[Mrs Moon]

No, they are not.

[David Mowat]

Well, as I was saying a few moments ago, there is no cure for this disease but it is possible to manage the symptoms and alleviate them. However, to do that we have to have a diagnosis, and that is the issue we are talking about today, particularly in the case of early-onset Parkinson’s disease.

On the prevalence of the disease, something like 130,000 people suffer from it—that is likely to be 160,000 by 2020—and 95% of them are over 60 years old. Because of that fact, there is a tendency in the medical profession and, indeed, in society at large, to think that it is a disease of older people. To an extent that is true according to the statistics, but we also know that something like 5,000 or 6,000 people under 50 have the disease. I will talk about the statistics a little more later, because the hon. Member for Torfaen did challenge them, and it is true that the numbers are all estimates. Nevertheless, the number I have is that something like 400 people under 40 have the disease. Incredibly, it is thought that a few dozen people get the disease under the age of 20, which is a terrible thing as it means that it is with them for their entire working lives.

Parkinson’s is a progressive disease caused by the death of cells containing dopamine. As we have heard, it causes tremors, slowness, speech impediment and gait disorder. Its severity varies, as recognised in some of the points made about the Department for Work and Pensions. There is no cure; the best we can do is to manage the symptoms by trying to address the lack of dopamine through techniques such as brain stimulation, and apomorphine is the most commonly used drug. The hon. Member for Torfaen mentioned the recent debate on Duodopa; I do not intend to go over that in detail, other than to say that it is very much a minority treatment, with something like 75 people receiving the medication. It is typically used when other treatments are not successful.

We all—the Government and the country more generally—need to build awareness of the prevalence of early-onset disease. The NHS Choices website has information on the local and national support groups we heard about a few moments ago. Parkinson’s UK does a huge amount of work in this area, and I would of course be happy to meet it and the hon. Member for Torfaen.
