Alzheimer's disease

More older Americans rely on Medicare and Medicaid

Data: Centers for Medicare & Medicaid Services; Chart: Andrew Witherspoon/Axios

Retirement in America is growing less secure, physically and financially, given the omnipresent threat and cost of serious illness or disease.

Why it matters: Qualifying for Medicare does not guarantee that older adults will skirt potentially ruinous medical bills. Millions of seniors have also come to rely on the taxpayer-funded program for lower income people — Medicaid — and there's no indication that will slow down.

Biogen's Alzheimer's revival meets with skepticism

Data: Money.net; Chart: Axios Visuals

Biogen was a shattered biotech company in March after it pulled the plug on its new Alzheimer's drug, but it recaptured Wall Street's good graces by looking at its data again and deciding to shoot for FDA approval after all.

Reality check: Alzheimer's affects almost 6 million Americans, and those patients and their families have desperately sought an effective treatment. But independent experts have not reviewed Biogen's data, and the industry isn't exactly on good footing right now when it comes to being forthright about its data.
