Many factors cause variations in physical and mental health across the lifespan. Understanding the causes and origins for variations in health due to aging is essential to help contributing to improve the health of Canadians. Jens C. Pruessner, PhD, joined the Douglas Institute Research Centre in 2000 to study the effects of acute and chronic stressors on neurodevelopment and neurodegeneration in healthy and at risk populations.
Jens C. Pruessner uses functional and structural brain imaging techniques - Positron Emission Tomography (PET) and Magnetic Resonance Imaging (fMRI) - to understand the changes that affect the brain as the organism is aging, especially in the context of acute and chronic stressors. In addition, he and his team investigate the effects of interindividual variations in life history on the brain, and the stress response.
They also try to understand age-related changes in hormonal regulation and their relation to depression. They also study the effects of acute stress on hormonal and central nervous system activation changes. Finally, they investigate the effects of hormonal replacement therapy on the aging human brain.
Their studies to date show that a variety of factors shape the stress response, which in turn seems to significantly affect the way the brain is aging.
