Now, researchers led by Dr. Dan Frenkel, Tel Aviv U, are working on a vaccine that promises to protect against Alzheimer’s and stroke by repairing vascular damage in the brain, even when symptoms of the disease are present. The drug works by inducing “an immune response against amyloid proteins in the blood vessels," says Frenkel, who adds, "In early pre-clinical studies, we've found it can prevent both brain tissue damage and restore cognitive impairment.” Plus, the drug may prevent hemorrhagic strokes. The vaccine has been successfully tested on animals and Frenkel is hopeful that this new approach may lead to a cure.
