Demi Lovato has been very open about her addiction problems in the past, and now she has revealed the ongoing repercussions of her battle with drugs.

The pop star took a drug overdose in 2018 and by all accounts, came very close to death following it. She had released a song called 'Sober' just weeks before it happened, which saw her admit that she had relapsed in her battle against addiction.

Now, in a new four-part docu-series that debuts on YouTube Originals on March 23rd, the former child star has revealed for the first time just how badly that overdose affected her.

The trailer sees her explain that her family were told that she had five to ten minutes to live, and that she had suffered a heart attack and three strokes. “I was left with brain damage, and I still deal with the effects of that today,” she told ABC. “I don’t drive a car because I have blind spots in my vision. For a long time, I had a really hard time reading. It was a big deal when I was able to read a book, which was like two months later, because my vision was so blurry.”

The 28-year-old Lovato had been in various rehab programmes and was sober for six years before her 2018 relapse.

Her family, as well as famous faces like Christina Aguilera and Elton John, also feature in the documentary.
