Having depression may increase your risk of developing Parkinson’s disease by up to three times, according to a new study.
Depression is known to raise the risk of a host of diseases including cancer and stroke, but although it is known to be more common among Parkinson’s patients than the general population, it remains unclear whether it is a cause or a symptom.
Researchers from Taipei Veterans General Hospital in Taiwan examined the medical records of 4,634 people who suffered from clinically diagnosed depression, and 18,544 who did not, over a ten-year period. They found that 66 people with depression, or 1.42 per cent, went on to be diagnosed with Parkinson’s during the next decade compared with 97 of those without depression, or 0.52 per cent.
After other factors such as age were taken into account, patients with depression were found to be 3.24 times more likely to be diagnosed with Parkinson’s than those without.
Even when researchers excluded the records of patients who were diagnosed with Parkinson’s shortly after their depression diagnosis, the link was still apparent suggesting that depression raises the risk of Parkinson’s over the long term.
In a joint announcement, three French Ministers expressed their support for people with dementia and their carers on World Alzheimers Day.
Marisol Touraine (Social Affairs and Health Minister), Geneviève Fioraso (Minister for Higher Education and Research) and Michèle Delaunay (Minister for the Elderly and Autonomy) also provided an update on the progress of the new Neurodegenerative Plan. This will be the continuation of Frances pioneering Plan Alzheimer.
Following the evaluation of the 3rd Plan Alzheimer (2008-2012) by Professors Joël Ankri and Christine Van Broeckhoven, four thematic working groups are being formed to identify the measures and actions of the new plan. The themes are:
improve diagnosis and early detection of the disease
respond to patients needs at each stage of the disease and in the entire country
increase awareness and conform to the highest standards of ethics, quality and welfare
increase the quantity and quality of research.
The new Neurodegenerative plan is expected to be finalised in the first quarter of 2014.
Highlights EU support for the coordination of national research efforts through the joint programming initiative on neurodegenerative diseases
More research, innovation and awareness is the solution to overcoming the societal challenges presented by dementia, argues Máire Geoghegan-Quinn.
Professor Leonard Van Den Berg, coordinator of the JPND-supported SOPHIA project, gave a brief insight into current progress on this biomarker project
At this moment, the key project objective is to finalise development of the web-based platform including a virtual biobank to integrate the core clinical dataset from patients from all participating centres with biomarker data obtained from different biosamples. The core clinical dataset has been defined and the required fields for data collection of neuropathology biomarkers, wet biomarkers (in CSF, blood) and imaging biomarkers (MRI, MUNIX) are being set up. Standard Operating Procedures (SOPs) for sample collection and biomarker measurement have already been developed for some of the biomarkers. Other SOPs are still work in progress using the results from variability and reliability analysis on small sample datasets. The SOPs will also include a monitoring and quality control mechanism. Longitudinal data will be collected and analysed once the system is up and running. In the future new biomarkers can be quickly optimized and/or harmonized using a standard approach, if required.
Recently it became clear that the Edinburgh Cognitive and Behavioural ALS Screen (ECAS) would be an excellent addition to the core clinical dataset that is collected from ALS patients: Collecting longitudinal reliable neuropsychology data would be useful to detect the specific profile of cognition and behaviour changes in ALS and to differentiate it from other disorders. Using the SOPHIA consortium, developers of ECAS are able to roll out and validate the screen throughout Europe within a short timeframe. The establishment of a consortium like SOPHIA has been instrumental to this effort, and will be just that for future biomarkers.
Where is the SOPHIA consortium making a real difference?
The European ALS community has established an active consortium ( www.ENCALS.eu) which holds several 2-3 day workshops per year among others about European collaboration on databases/biobanks, molecular biomarkers, and neuroimaging, and members have generated a series of consensus statements and standard operating procedures for biomarkers. These types of initiatives are an excellent foundation for European collaboration but more focused projects and funding is required for larger international collaborations to obtain the numbers of samples necessary to perform large biomarker validation studies in ALS and other motor neuron diseases. This is where the SOPHIA consortium is making the difference, as the results of its works will be a common European strategy for the prioritization and selection of candidate biomarker domains for optimization and harmonization and a permanent interactive European ALS biomarker tool for all researchers to enable optimization/harmonization of novel biomarkers using an integrated and robust pan-European ALS methodology.
In your opinion, what is the added-value of JPND support for this project?
The benefit of JPND support for the SOPHIA project lies in communication of project results to the wider ND disease society, which is essential for sharing all methods, database, biomarker essays, and biomarkers in SOPHIA with other members of the scientific community devoted to ALS and to other neurodegenerative diseases. The concept of this project (pan-European SOPs) can be expanded to other neurodegenerative disease areas resulting in a driving force for shared biomarker research.
What has been your experience of this research collaboration to date?
One year into the project it is very clear that this is a group of highly motivated investigators, keen to set up a platform to promote biomarker research for neurodegenerative diseases. All involved feel this can only be truly accomplished at a European level and are therefore eager to collaborate. Each partner in the project is actively involving his/her colleagues in order to make sure they have the right people working on each of the different sub-projects. This has been very helpful in progressing the tasks that the consortium has set itself and will result in deliverables of high standard.

JPND is collaborating with the Ambient Assisted Living Joint Programme on Sept. 25th at the 2013 AAL Forum, in Norrköping, Sweden
Assisted living technologies such as ICT/smart technology offer enormous potential in the development of effective measures for prevention, intervention and care for people with neurodegenerative diseases and their carers.
To join forces and align priorities in this area, JPND and the Article-185 initiative – Ambient Assisted Living Joint Programme (AAL JP), are working together towards developing recommendations for joint actions in the area of assisted living technologies for neurodegenerative diseases.
A JPND Alignment Action Group, containing members of both initiatives, is working to identify where JPND and AAL JP priorities and activities can be aligned, or new activities identified, and is organising actions to bring together important stakeholders in this area including users, academia, small businesses and the ICT and service industries.
The Action Group is organising a session entitled AAL & JPND: Partnering to meet needs in the area of neurodegenerative diseases/dementia, at the 2013 AAL Forum in Norrköping, Sweden, at 11am on Sept. 25th. The Forum is the annual platform for the ever-increasing European AAL community to meet and discuss topics relevant for improving the AAL JP as well as the adoption of AAL solutions in the market.
In this session information will be presented about JPND, on relevant AAL solutions (showcasing some AAL projects) followed by discussions on their potential impact as well as the way forward.
A JPND poster has been designed to promote the session at the Forum. The poster can be viewed at the filelink below.

Two studies recently released provide more insight into diagnosing and treating Parkinsons disease.
One emerging area of study focuses on how the build-up of proteins in the brain may lead to neurodegenerative diseases. Interactions between two of those proteins, amyloid and tau, may distinguish Parkinson’s disease from other degenerative brain diseases like Alzheimers. This research is part of the Parkinsons Progression Markers Initiative, a global research project to better understand the disease sponsored in part by the Michael J. Fox Foundation for Parkinsons research.
The other study, published in the journal Nature Neuroscience, found that an anti-cancer compound protected dopamine-making neurons from death in a mouse model, and also prevented behavioral abnormalities similar to those seen in Parkinson’s disease.

The structure of Portugal’s National Dementia Plan has been submitted to the Ministry of Health for approval.
The submission follows a May 2013 meeting, where a group of dementia experts persuaded the government that existing dementia prevalence figures are sufficiently accurate to allow the next phase of the plan to proceed right away. The group put forward a prevalence figure of 160,000 people with dementia in Portugal, which negated the need for a dedicated epidemiological study – an expensive and lengthy process.
The group included psychiatrists, neurologists, general practitioners, researchers, members of the municipalities and representatives of Alzheimer Portugal. Their work was coordinated by Prof Joel Menard, an architect of the original French Alzheimer Plan.
The next phase of the national plan is a study to determine the needs of people with dementia. This study is already prepared and can begin very quickly. It will begin in the north of Portugal and will return results within six to nine months According to Álvaro de Carvalho, the Coordinator of the National Mental Health Programme, the rest of the country will follow in turn.
