The plasma exchange slowed Rich's epigenetic aging rate by the equivalent of 25 years, from a 71-year-old rate to a 46-year-old rate. The 25-year reduction in aging rate from the plasma exchange was maintained across 6 months of measurement, and cognitive abilities bounced back significantly. Intergenerational plasma exchange only provides benefit when there is a meaningful biological age difference between donor and recipient. Brian donated plasma to his father Rich, who was experiencing a precipitous decline in cognitive abilities, in an intergenerational plasma exchange.
