The first full update since 2012 gives its strongest marks to CGRP drugs and Botox, but keeps decades-old propranolol and topiramate on the same list.
The health headlines move fast and most coverage gets the science wrong. Every day, Dr. Ravi Kumar, MD, a board-certified neurosurgeon, cuts through the noise: what a new study or story actually says, what it doesn’t, and what it means for you. Researched, sourced, and reviewed before it’s published.

A BMJ study of all 1,712 former NFL players who died between 2008 and 2021 put the true rate of CTE at death somewhere between 24.5% and 97.7% for the most recent six years, a range wide enough to show how little the headline 93% figure actually settles.

Cochrane's updated living review of 80 trials and 29,861 people gives high-certainty evidence that nicotine e-cigarettes help more adult smokers quit than patches or gum, with serious side effects rare in every group.
