Neuroscientist Discusses Biden's Cognitive Abilities and Aging A report by special counsel Robert K. Hur, which did not prosecute President Biden for handling classified documents, included an assessment of Biden's cognitive abilities. The neuroscientist emphasizes that forgetfulness is normal with age and doesn't necessarily indicate memory deficits. They differentiate between ordinary forgetting and more significant memory loss. The article urges a focus on candidates' capabilities rather than their ages, and emphasizes the need for a national conversation based on science, not politics.
