The condensed version? There's a substance called amyloid that's present in everybody's blood. Most people produce a protein that breaks it down. Alzheimer's patients don't - they have several hundred times too much amyloid in their systems, and it passes the barrier into the brain. The amyloids produce a plaque that eventually kills brain cells.
They've found a synthetic human protein that seems to destroy the amyloids.
In lab tests (presumably on animals) it's worked beautifully, and with little or no side effects. It may be a couple of years before human testing is set up.
They also don't know if it will be a one-off injection or if folks will have to have periodic treatments. People will be chosen for the tests according to the amyloid levels in their blood.
Looks really promising, though.
(I didn't put this in EtU on purpose, because this seems like big current news to me.)
