Another study showed that a reduction of ...Androgen therapy may slow progress of Alzheimer's disease
... "This study raises the possibility that androgen replacement therapy might lower the risk for Alzheimer's, but this is far from proven," says Sam Gandy, MD, PhD, chair of the Alzheimer's Association's Medical and Scientific Advisory Council and director of the Farber Institute for Neurosciences at Thomas Jeffe......st of risky blood transfusions or expensive enzyme replacement therapy.
