Study Summary
This trial will look at whether older adults with anxiety symptoms experience a loss of pleasure or motivation when exposed to inflammation. This will be evaluated using self-report questionnaires, computer tasks, and during a brain scan. Endotoxin is a treatment for Anhedonia that was previously approved by the FDA for a different condition. This treatment is free.

Michael Gill holds a Bachelors of Science in Integrated Science and Mathematics from McMaster University. During his degree he devoted considerable time modeling the pharmacodynamics of promising drug candidates. Since then, he has leveraged this knowledge of the investigational new drug ecosystem to help his father navigate clinical trials for multiple myeloma, an experience which prompted him to co-found Power Life Sciences: a company that helps patients access randomized controlled trials.
