Camera Study – Pacific Parkinson's Research Centre

People with Parkinson's disease (PD) are needed for a study with the Pacific Parkinson's Research Centre that is developing a novel, privacy compliant monitoring tool for people with PD.

The study is specifically looking for participants who: 

  • Have a confirmed diagnosis of idiopathic PD
  • Are capable of providing informed consent 
  • People with more advanced disease are encouraged to participate (only simple tasks like finger-tapping and walking will be requested) 

Regular monitoring of body movement, mood, and other disease symptoms in this population is important to assess disease progression and inform treatment decisions – however, assessments of symptoms are typically only performed once a year due to economic constraints.

The aim of their study is to ultimately develop a smart camera system that preserves your privacy, yet can still measure body movement and mood (without the need for wearable sensors) in a home setting. This information may provide healthcare providers with a more comprehensive insight into a patients disease status. 

Please contact Ravneet Mahal at 604-822-7763 or if you are interested in participating or would like more information.

Time Perception in Parkinson's Disease (University of Oxford)

Parkinson’s disease is known to affect parts of the brain that are thought to be involved in perceiving the passage of time, but the nature and degree of any actual time perception problems that result is not well understood. The aim of this research is to determine whether time perception is altered in Parkinson’s disease (PD) and whether this can be accurately quantified. If so, measures of changes in time perception could be potentially used in future as a test that could help diagnose PD and address symptoms.

The research is conducted completely online. There is a very brief questionnaire collecting information including participant age, gender, whether you have PD and what other conditions/medications you may have. 

You will then complete a task that consists of two parts. Firstly, you will be shown two images in sequence, one of which appears on screen for slightly longer than the other and asked to say which was there the longest. This is repeated multiple times. Then the same thing is done again, but instead of images, using two audio tones of slightly different duration played in sequence. This whole task should take 20-30 minutes. 

The study is being conducted by the NeuroMetrology group in the Nuffield Department of Clinical Neurosciences at the University of Oxford. If you have any questions, contact

Animal Assisted Interventions Study (University of Groningen)

Volunteers needed for a questionnaire study on service dogs for Parkinson's disease. Individuals may be diagnosed with Parkinson's, Lewy body dementia, or be caregivers of individuals with these diagnoses. Participation is confidential and individual responses will remain anonymous.

Participants do not need to have a service dog to complete the survey. 

Study Information

Service dogs may be of great assistance to those with Parkinson's disease or Lewy body dementia. Thus far, research on this topic has been extremely scarce. However, these highly trained animals may assist in areas including retrieving hard to reach items, finding help for owners in distress, providing balance support, encouraging exercise, and reducing loneliness.
