Why do child actors have so much trouble coping with adulthood?

Gayatri Ayyer, a counselling psychologist, believes that children who rise to stardom early on have unique problems. She said, 'Their schedules get disrupted, they're losing out on doing things normal children to like going to school or playing with friends or spending time with their families. They are pressurised into schedules which are overwhelming for them both physically and mentally and all this takes a toll.'

There's also the aspect of these kids becoming major wage earners for their families, thrusting them into adult roles when they're still kids, roles they're not equipped to deal with it emotionally or physically. Ayyer adds, 'In most cases the family isn't prepared for this sudden influx of money and they end up putting more pressure on their child to earn money. The child too due to this unrelenting pressure could exhibit bizarre behaviours temper tantrums, psycho somatic problems, or substance abuse.' In essence, they never learn to grow up!

Here's a list of some other child stars who broke under the pressure of stardom:

Macaulay Culkin

The little boy who acted in the Home Alone series and dated Mila Kunis for nearly 10 years admitted after years that he had been addicted to heroin and prescription drugs, the latter of which bought him an arrest. He has also admitted to smoking marijuana.

Haley Joel Osment

The Sixth Sense actor was arrested in 2006 for driving under the influence. He crashed is car suffering from minor injuries and was briefly hospitalised. He was also charged for possession of marijuana.

Britney Spears

Britney Spears was America's sweetheart, until she finally broke. Since the mid 2000s she's been in and out of rehab centres, spur of the moment marriages and at one point she walked into a salon and shaved her head showing the public that she had officially reached breaking point. Fortunately, since then Spears' has sobered up and is continuing with her music career. (Read more: Miley Cyrus' twerking act: Why do child actors have so much trouble coping with adulthood?)
