Allegedly 6 MILLION Americans currently suffer with it/from it. I don't know how many worldwide. Good news for a change?
Aduhelm
"Instead of judging Biogen’s treatment solely on its effects on cognition, the FDA granted a conditional approval based on Aduhelm’s ability to clear the toxic proteins, called beta-amyloid. In order to continue marketing the drug, Biogen will need to complete a large clinical trial to confirm that removing the plaque has cognitive benefits, the FDA said. If that study fails, the FDA has the authority to rescind its approval.
In approving the drug on a conditional basis, the agency departed from decades of regulatory precedent, setting a new bar for treatments with considerable potential but unproven benefits — a standard that could also be applied to other devastating disease."
..."Biogen believed it could succeed where the others failed; it designed Aduhelm to be more potent and therefore better able to eliminate amyloid plaques than earlier drugs. The company also focused on administering Aduhelm to people with mild cognitive impairment or the earliest signs of Alzheimer’s, before brain cells were too damaged to stem the tide of the disease."

"Biogen's controversial new FDA-approved drug for Alzheimer's, a disease 500,000 Americans are diagnosed with each year, will cost $56,000 annually, Axios health care editor Tina Reed writes.
Why it matters: It's experts' nightmare drug-spending scenario — an extremely expensive product that millions of desperate patients could be eligible for. And it may not even work.
