David Cassidy, the pop star and actor who set teen girls’ hearts aflutter as the star of the ’70s sitcom “The Partridge Family,” has revealed that he is battling dementia.

In an interview with People, Cassidy, 66, admitted that he is dealing with the memory-loss disease, which took its toll on both his grandfather and his mother. “I was in denial, but a part of me always knew this was coming,” Cassidy said about the moment when he was diagnosed with dementia. He also announced that his concerts this past weekend would be his last after a show in southern California Saturday in which he slurred his words and fell off the stage.

“I want to focus on what I am, who I am and how I’ve been without any distractions,” he said about retiring. “I want to love. I want to enjoy life.”

In recent years, Cassidy has made headlines more often for his personal travails than for his performances. He faced DUI charges on three separate occasions in November 2010, August 2013 and January 2014. In February 2014, his third wife, Sue Shifrin-Cassidy, filed for divorce. One year later, Cassidy filed for bankruptcy and in October 2015 was charged after a hit-and-run accident. He also entered rehab in 2014 to deal with substance-abuse issues.
