"Intravenous immunoglobulin (IVIg), a therapeutic biologic composed of pooled antibodies from tens of thousands of donors"

Pooled plasma increases the risk of spreading prion diseases, and other infectious agents. IIRC, when the Clintons were selling pooled plasma taken from Arkansas prisoners to Canada, it caused an AIDS outbreak.

Using preclinical models, the research team tested whether focused ultrasound combined with microbubbles, a non-surgical method used to briefly increase the permeability of the blood-brain barrier, could improve the delivery of IVIg to the hippocampus, an area of the brain involved in learning and memory and severely degenerated in patients with Alzheimer's disease.

As is my habit I will play Devil’s advocate.

Lowering the permeability of the blood-brain barrier would necessarily raise the risk of a pathogen entering the brain.

Off course no treatment comes without attendant risk.

In my humble opinion, Alzheimer’s is a disease that will have a cure within 5 years.

What about adult stem cells?
