Individuals with a particular sleep
\ndisorder are much more likely to develop Parkinson\u2019s disease, a connection that
\nhas provided a unique research opportunity for Dr. Ziv Gan-Or, an assistant
\nprofessor at
\nMcGill University and a researcher in the Montreal Neurological Institute and
\nHospital. Funded in partnership with Pedaling
\nfor Parkinson\u2019s in Honour of Dr. John Newall, Dr. Gan-Or has recruited more than 1,000 of these individuals from around the
\nworld for a study to examine the genetic factors that might link their
\ncondition with neurodegeneration. The goal is to identify a genetic marker that
\nwould indicate the early onset of Parkinson\u2019s disease in any individual, so
\nthat it could be treated as soon as possible.<\/p>\n

Ziv Gan-Or was an MD-PhD student at Tel Aviv University when he encountered an unusual sleep disorder that piqued his curiosity. Known as REM sleep behaviour disorder (RBD), most of the individuals who suffer from this condition go on to develop other conditions such as Parkinson\u2019s disease and dementia with Lewy bodies, aggregates of protein that build up in neurons and interfere with their function.<\/p>\n

\u201cIn order not to act out our dreams, our brain shuts off our voluntary muscles during REM sleep, when we dream,\u201d he explains. \u201cPeople with RBD lose this inhibition and they do enact their dreams. It has become clear that what these people really have is the early stage of a neurodegenerative disease.\u201d<\/p>\n

Gan-Or, who is now an assistant professor at McGill University and a researcher in the Montreal Neurological Institute and Hospital, was especially intrigued by the high levels of the protein alpha-synuclein found in the brains of these individuals. Since this kind of build-up has been directly associated with the onset of Parkinson\u2019s disease, Gan-Or has spent the last few years establishing what will be the world\u2019s largest study of RBD patients. Working with 18 centres all over the world, this undertaking has recruited more than 1,000 people with the ailment, as well as another 3,000 people without it, who will serve as control subjects.<\/p>\n

This research will analyze the genetic make-up of all the participants, with a specific emphasis on the gene encoding alpha-synuclein. Because it is already known that most of those with RBD are likely to develop Parkinson\u2019s disease at some point over the next decade, the resulting genetic patterns could reveal important indicators for conversion from RBD to Parkinson\u2019s disease. Gan-Or\u2019s research is made possible through a New Investigator Award for $90,000 over 2 years from Pedaling for Parkinson, in honour of Dr. John Newall<\/p>\n

\u201cWe can identify people at risk at a much earlier stage,\u201d he says. \u201cThis program is not intended to develop a drug but once there is a drug to prevent Parkinson\u2019s disease, our study would help with identifying patients at a much earlier stage.\u201d<\/p>\n

Gan-Or is also going to conduct a series of experiments to examine how alpha-synuclein spreads throughout the body. By outlining this process in detail, he suggests, it could become clear how to design treatments that would improve the lives of patients by halting the disease in its tracks. \u201cIt will allow us to better understand how genetics affect progression,\u201d he says. \u201cIt may serve as a target for future development of treatment, aimed at stopping alpha-synuclein progression.\u201d <\/p>\n
