Dark Truth: David Cassidy Admits Booze Caused Dementia In Never-Before-Seen Interview

David Cassidy died on November 21, 2017 at the age of 67 when his liver gave up, followings years of heavy drinking. His untimely passing broke the hearts of fans around the world, but according to a new documentary, his close friends were not surprised.

"There's a lot of tragedy in the latter part of his life, and that's why the band becomes a family," a former pal of the actor says in the new video teaser.

In a shocking never-before-heard interview before his tragic death, Cassidy himself admits that his alcoholism—brought upon by his depression and dark demons—is what caused his liver disease. Little did he know, it would eventually lead to his early demise.

I just met with the doctor and my liver… I have a liver disease. My life has changed dramatically," Cassidy says in an interview, months before his passing.

The first few days I was unconscious and near death. The last week or so my memory has come back. That's such a blessing. That means I'm cognizant of my surroundings. That I'm alive and it's daytime, and I know what day of the week it is," he happily continues.

As RadarOnline.com readers know, Cassidy began suffering from memory loss in his final years. He even began cutting down on his performances due to his declining health.

"There is no sign of me having dementia at this stage of my life. It was complete alcohol poisoning. And the fact is I lied about my drinking," says the performer in the newly-released interview.

RadarOnline.com previously reported that Cassidy admitted to being "in denial" about his dementia, but eventually said he "knew this was coming."
