The four part documentary series “Demi Lovato: Dancing with the Devil” (YouTube, streaming) looks at the chaos in the pop star’s life that led to her near fatal overdose in 2018 and her consideration of it now with director Michael D. Ratner. 

She was asked at a press event last month why she wanted to tell the very personal details. “Over the past couple years I’ve heard a lot of stories about my life, and what people think has happened,” she said. “I wanted to set the record straight.”

Some of the details are pretty shocking — including a pair of strokes that accompanied the near overdose. “I was left with brain damage and I still deal with the effects of that today. I don’t drive a car because I have blind spots in my vision. I also for a long time had a really hard time reading,” Lovato said. “I dealt with a lot of the repercussions and I feel like they kind of are still there to remind me of what could happen if I ever get into a dark place again. And I’m grateful for those reminders.”
