Vertigo Voodoo: A Crazy-Sounding Cure That Actually Works

A sequence of positional changes sounds like voodoo, but is actually an effective way to cure benign paroxysmal positional vertigo (BPPV). This will not be my typical Science-Based Medicine post. What it is not This will not be: About vaccines, diet, pseudoscience, quackery, or alternative medicine A critique of a questionable treatment, claim, or practice

BladderMax: Fake News and Outrageous Headlines

A newspaper ad for BladderMax is disguised as a news story reporting “the end of bladder leakages.” The information is inaccurate and the headlines are preposterous.
