The Demi Lovato that we are seeing all over the news, is clearly not the same girl who won over the hearts of Disney Channel fans years ago. So what happened to that sweet girl people saw on TV? Or was it actually TV that changed her?

The news of Lovato's alleged drug overdose has been a shock to the entertainment system. Though the star has been outspoken about past issues with mental health and drug abuse, her relapse after six years of sobriety are making people question how this could happen.

Many psychologists believe it may be the curse of the child star. Clinical psychologist Eileen Kennedy-Moore explained, "Childhood is about finding out who you are and being able to relate to others, and those things are harder to learn when you're famous. That amount of public scrutiny makes it hard on kids to do that. They can't mess up. So they have to adopt a very self-assured, precocious identity very quickly," she told the Atlantic.

Lovato began her time in the spotlight as a very young child on the series 'Barney & Friends.' She then went on to be the lead on her show 'Sonny with a Chance,' as well as in the film franchise 'Camp Rock.'

With the curse of the child star gaining similar victims such as Justin Bieber, Linsday Lohan, and Amanda Bynes. Perhaps the entertainment industry should question the treatment of these young celebrities.
