Hospital reports and contemporaneous obituaries, including those from NPR and the BBC, listed liver failure and multiple organ failure as the immediate causes of death. The Los Angeles Times obituary confirmed that the underlying cause was long-term alcohol abuse.
Cassidy had publicly announced in February 2017 that he was living with dementia, after a performance during which he struggled to remember lyrics and appeared to fall off the stage. However, later reporting based on a documentary — covered by CBS News and LiveScience — quoted Cassidy saying there was “no sign” of dementia and that he had lied about his drinking.

Cassidy’s most famous song, “I Think I Love You,” was released in 1970 and reached #1 on the Billboard Hot 100. The track was performed by the fictional band on The Partridge Family, but Cassidy’s voice was the lead. The song became a defining anthem of the era and sold millions of copies worldwide.
Albums and Discography
Cassidy released several solo albums during the 1970s, including Cherish (1972) and Dreams Are Nuthin’ More Than Wishes (1973). His final studio album was Then and Now (2002).

After the end of The Partridge Family in 1974, Cassidy continued to perform live and record music, though his commercial success declined.

What Happened to David Cassidy in 2017? Final Days and Funeral
The Dementia Announcement
In February 2017, Cassidy told People magazine that he had been diagnosed with dementia. He said that he had been struggling with memory loss and that his mother had also lived with dementia. The announcement came after a performance in California where he had trouble remembering lyrics and appeared disoriented on stage.
The Documentary and the Reversal
Later in 2017, a documentary about Cassidy’s life included interviews in which he suggested that he did not actually have dementia and that he had misled the public about the severity of his drinking. The documentary, as reported by the AARP and by CBS News, quoted Cassidy saying there was “no sign” of dementia and that his health problems were tied to alcohol.
No second opinion regarding the dementia diagnosis was made public. Medical experts quoted in subsequent reporting noted that alcohol-related cognitive decline can closely mimic the symptoms of dementia, which may explain the conflicting accounts from Cassidy and his family.
Funeral and Burial
Cassidy’s funeral was a private affair, and his family requested that details not be made public. His body was cremated, and the location of his ashes has not been disclosed. No public memorial service was held.
