'The Partridge Family' star is grateful for the well wishes after his scary diagnosis.
David Cassidy is giving thanks.
In the wake of his diagnosis with dementia, the Partridge Family singer and actor tweeted out to his fans on Tuesday, writing, "Thank you to everyone who has reached out offering their love and support."
This week, ET confirmed the 66-year-old performer had been diagnosed with the memory loss syndrome, which Cassidy recently shared he had feared for some time.
"I was in denial," Cassidy admitted to People, "but a part of me always knew this was coming."
Cassidy opened up to ET last year following an onstage incident, explaining that it was prompted by medical procedures on his eyes.
