The Lancet’s Commission on Health & Well-Being

The Lancet announced a new commission and campaign for adolescent health, demanding recognition and action for the largest generation of 1.8 billion adolescents and young people in human history.

The commission includes reports on biological changes in adolescence, the possible global threats to adolescent development, and a multilevel call to action for worldwide health and sustainability, for us and the generations to come.

The 2015 Cycloventure Challenge – A Success!

Research funded by the CYCLOVENTURE CHALLENGE 2015

It is essential to identify, early in adolescence, determinants of the brain that will predict the onset of mental health problems. This year, your contributions help to perform imaging examinations using Magnetic Resonance Imaging, (MRI) to measure the brain activity of teenagers who will be linked to future problems with depression.

Thank you to all who joined us!

2014 edition: What an accomplishment!

About thirty cyclists pedaled under the banner of the CHALLENGE and helped raise over $6,000 in donations and investments. These contributions have enabled our research team to perform MRI scans on young adolescents in the early stages of mental health problems. We have identified a brain marker in 14-year-old adolescents that predicted the persistence of symptoms of attenuated psychosis two years later. These results contribute to effective identification of these at-risk youth for future preventive actions.

It was a pleasure to cycle and run with you!

Scientific Soirée 2015 – Innovation and the Role of Community Partnerships in Drug Prevention

What is a scientific soirée? This event aims to encourage opportunities for exchange between practitioners, experts, and researchers on topical themes in child psychiatry, along with school stakeholders and the public.

On May 26, 2015, a panel of 6 experts presented topics related to innovation and the role of community partnerships in drug prevention. After two hours of presentations and questions, the participants and experts had the opportunity to discuss in a less formal setting with a light cocktail.
