My research explored the Neuropsychology and Neuroimmunology of Alzheimer's Disease. I conducted a human clinical trial and a drug trial using a genetically modified mouse model of Alzheimer’s Disease. The human cohort consisted of individuals with early-stage Alzheimer’s Disease, clinically referred to as amnestic Mild Cognitive Impairment (aMCI). Women are disproportionately affected by Alzheimer’s Disease, accounting for nearly two-thirds of cases, so in the human cohort I examined sex-specific differences in pathophysiology. I then evaluated the therapeutic potential of cannabidiol (CBD) to modify relevant pathophysiology in the genetically modified mouse model.

My thesis used electroencephalogram (EEG) and a drumming task to examine how tempo changes are processed neurologically and behaviourally.
