The single-gene mutations directly responsible for early-onset Alzheimer's disease do not seem to be involved in late-onset Alzheimer's, and researchers have not found a specific gene that causes the late-onset form of the disease.
The NFLâs worst defense in 2015 are expected to be the Atlanta Falcons, Jacksonville Jaguars, Tennessee Titans, Chicago Bears and Tampa Bay Buccaneers (not necessarily in that order).
This is a list of the most consecutive starts and games played by a player by position in the NFL. Brett Favre's starts streak of 297 games is the longest all-time. Among defensive players, Jim Marshall's starts streak of 270 is the longest all-time. Of special note is punter Jeff Feagles, who played in 352 consecutive games which is the longest of all-time for a special teams player. Special teams players are not credited with starts in the NFL.
