Putin's Foe Likely Suffering From Long-Term Effects Of Nerve Agent

The long-term impact of Novichok isn't clear but some of Alexei Navalny's ailments appear to coincide with researchers' understanding of nerve agents.

Vladimir Putin’s most prominent critic is slowly starting to eat again, after a 24-day hunger strike in prison. Experts say the Kremlin not only holds the keys to Alexei Navalny’s freedom… but to knowledge of health problems he still faces from being poisoned. "We don't have a lot of experience with this in people," says Lewis Nelson, the Chair of the Department of Emergency Medicine at Rutgers New Jersey Medical School. Some doctors say the dissident is likely experiencing long-term effects from exposure to Novichok nerve agent last year. And at a prison east of Moscow months later, the 44-year-old said he was denied adequate health care. So began a dangerous hunger strike.
