Hayden Panettiere was 16 when medication first arrived in her life in Hollywood.

Ahead of a purple carpet occasion for the hit sequence Heroes, she has said someone on her workforce handed her a capsule to assist amp up her vitality. The hit sci-fi NBC sequence had catapulted the teen into a family title – and that introduced with it intense stress and exhaustion she says felt overwhelming.

“Within minutes, a wave of energy washed over me, like I’d just woken up from the most refreshing night’s sleep of my life,” Panettiere wrote about that capsule in her memoir, which was launched just months before her loss of life.

She called it “the gateway drug that ushered me toward the good of pharmaceuticals and the downfall of addiction”.

The star’s sudden loss of life at the age of 36 has positioned a renewed focus on her struggles with psychological well being and substance abuse, and re-ignited a dialogue about the pressures of Hollywood on little one stars.

The coroner’s workplace in Greenville, South Carolina said crews handled a girl in “cardiac arrest” and her post-mortem confirmed “no signs of trauma”.

No cause of loss of life has been launched, though further checks are yet to be accomplished.

Audio from police dispatchers and crews who responded to the tackle said they were responding to a “cardiac arrest” and detailed their efforts to resuscitate the girl after a potential “overdose”. Panettiere’s ex boyfriend, Brian Hickerson – who has admitted to abusing her – and his brother Zack, were with Panettiere when emergency providers came, according to a police report.

There is no suggestion of wrongdoing on their half, according to police.

It is not identified if medication or alcohol performed a issue in her loss of life, but the US Drug Enforcement Agency is becoming a member of an investigation into her loss of life, according to US media reports.

Panettiere is one of many actors who has overtly struggled with habit after publicity to fame at an early age, which habit consultants informed the BBC can put individuals at threat for psychological well being and substance abuse points.

It can sometimes appear to the relaxation of the world that little one actors have “everything” at their fingertips – like fame and cash, said Lucas Trautman, the medical director of Oxford Treatment Center, an habit therapy centre in Mississippi.

“But it’s important to remember that they were also exposed during a developmental time to many adult aspects of life that the rest of us weren’t – including traumatic experiences – and so that gives them unique risk factors for addiction,” Trautman said.

Panettiere’s loss of life comes after she revealed a memoir where she mentioned at size her points with habit, her postpartum despair and the loss of her 28-year-old brother.

Panettiere’s determination to publicly share her struggles is worthy of respect, said William Moyers, the vice-president of public affairs for Hazelden Betty Ford, the largest nonprofit habit therapy supplier in the US. But he said the fixed public scrutiny she confronted may not have allowed her room to tackle her psychological well being in personal.

“Her entire life from the beginning was centred in the intense public spotlight, and this didn’t give Hayden much in the way of a respite,” said Moyers, who has been in restoration from an habit since 1989.
