Brains and Losses: The Bottom Line on Aging and Financial Vulnerability is a project from Marketplace that explores research on how the aging brain may become more susceptible to financial scams. Marketplace Morning Report host David Brancaccio’s reporting on this topic took him across the country to meet alleged fraud victims and their families and covers scientific and legal research.
