He's was suffering from this for 5 years
For the final few years of his life, Biden suffered from brain cancer. In May 2010, he was admitted to
Christiana Hospital in
Newark, Delaware, after complaining of a headache, numbness and paralysis; officials stated that he had suffered from a "mild stroke." Later that month, Biden was transferred to
Thomas Jefferson University Hospital in
Philadelphia and kept for observation for several days.
In August 2013, Biden was admitted to the
University of Texas MD Anderson Cancer Center in Houston, after experiencing what
White House officials called "an episode of disorientation and weakness." On May 20, 2015, he was admitted to
Walter Reed National Military Medical Center in Washington. Ten days later, Biden died there.
