The Young Blood Institute discusses the potential benefits of therapeutic plasma exchange (TPE) for aging-related conditions, including Alzheimer’s disease. Traditionally used for autoimmune disorders, TPE removes and replaces plasma with components like albumin or immunoglobulins, helping clear harmful substances from the blood. TPE has shown promise in slowing progression in conditions like Alzheimer’s by potentially reducing neurotoxic proteins linked to age-related cognitive decline. The article highlights the historical development of blood exchange therapies and modern applications, suggesting that TPE may play a role in addressing broader age-related health issues, though further research is necessary.
