Pondering Ketones in Brain Aging and Alzheimer's Disease with Stephen Cunnane

I talk with Professor Stephen Cunnane of Sherbrooke University about emerging evidence that ketones can protect neurons in the brain against dysfunction and degeneration during aging. The ability of neurons to utilize glucose as an energy source is impaired in Alzheimer's disease, but the neurons can still utilize ketones. In addition, ketones can activate genes that encode proteins that help the neuron withstand stress and form new synaptic connections.
