Brother Morgan hopes the heart-breaking video will strike a chord with Mariah and go some way to mend the long running family feud that has torn the Carey family apart. 

In a video filmed this week, Alison, 54, speaks directly to the ‘I’ll be There’ singer in a moving message, she says: ‘Mariah I love you, and I desperately need your help, please don’t abandon me like this.’

in a previous video, seen by Daily Mail Online, made on September 15 last year by Alison’s brother Morgan Carey,  Alison was at her lowest point  - 24 hours after she was taken off a ventilator keeping her alive in hospital.

Morgan made the video after being forced to intervene when he claims to have discovered a family member signed a ‘do not resuscitate’ order on Alison should she have a seizure.

Morgan, 55, wanted to prove Alison was lucid and had her faculties about her.

In the short clip the penniless former prostitute is spaced out  and slurring her words as brother Morgan asks for her permission to have the order lifted.

Morgan says: ‘Alison, look at me, you’re Alison Carey, are you Alison Carey?’ She responds: ‘Yes’.

Morgan continues: ‘Today is September 15, 2015?’

‘Yes’, she replied.

‘[Redacted]  signed a “do not resuscitate”…do you want to revoke that order?’

Morgan asked the question three times and she responded, ‘I do’, each time.

Morgan hopes the heart-breaking video will strike a chord with Mariah and go some way to mend the long running family feud that has torn the Carey family apart.

He’s hoping Mariah, who has an estimated net worth of $510 million, will put her hand in her vast pocket and pay for Alison’s health care.

Mariah, known for her lavish lifestyle, wears a $7 million engagement ring given to her by boyfriend, Australian billionaire businessman James Packer in January.

Packer is estimated by Forbes to be worth $4.7 billion - the fourth-richest person in Australia.

A representatives for Mariah denies the claim that she has not helped her sister. 'Through the years, Mariah has spent hundreds of thousands of dollars supporting Alison and her children,' the rep told Daily Mail Online. 'In fact, Mariah has supported her extended family for over two decades.'

Morgan says he understands that Mariah  hasn’t spoken to her sister properly since they had a huge argument in 1994 following her 1993 wedding the record producer Tommy Mottola

Alison revealed she worked as a prostitute in New York as a young woman to clothe and feed her family before Mariah found fame

Morgan, speaking to Daily Mail Online from his home in Italy, reveals that following the attack in April, Alison spent a short time at a mental hospital in New York  after a bizarre episode in the street near her home.

With a broadside to his other sister, he says: 'Because Mariah has not found it in her heart to help Alison get the care she requires there are times when Alison forgets or is unable to take her medication and this sometimes precipitates problematic behavior.'

He said: 'Alison was institutionalized for observation after being found wandering in the street barefoot and partially dressed, causing the police to be concerned.

'Her behavior was caused as a result of damage done in the attack and her having missed the medications she was taking.'

Morgan says that due to the severe brain damage, Alison suffers from memory loss, seizures, and occasional periods  loss of consciousness.

'Alison's brain scans show severe damage,' he explains.

Alison was released from the mental health facility after a few weeks.

Morgan added: 'The worst is yet to come and Mariah has it in her power to at least ensure a soft landing and avoid a life time of regret about missing this opportunity to forgive and help her only sister.'

‘I would be hopeful, although I am not encouraged by the past, that Mariah would step up because she’s in a position to step up.

‘We’re talking about small change to these people, her fiancé is a billionaire.

‘The least they could do is put Alison in a good hospital and make sure she gets the care she needs.

‘Mariah is the one person in the family who could actually make a real meaningful difference to Alison’s life.’

Morgan says he flew from Maui last August to be at his sister’s bedside when she took a turn for the worse, but Alison’s mother and sister didn’t show. It was then that he took a video of her in the hospital.

‘It was painful for her to speak, you could hear the raspiness in her breath, she had had a tube down her throat for so long.

‘She looked like she had been beaten down by this whole experience, her eyes were foggy, her skin jaundice and she had very little motor control.

‘Every effort, every movement was very labored and painful and difficult – but she was very much alive.

‘I wanted to be able to prove that she was lucid, that she understood who she was, where she was, what was going on around her.

Morgan says Alison inherited $1.6million from her father Alfred Carey, when he died in 2002, and she set up trust funds for her children. Alison recently left hospital and is being cared for by a Patient Advocate and staying at the advocate’s home in New York.

‘I wanted people to see that she was a human being and that someone else shouldn’t have the decision to decide whether she live or die.’

Despite coming close to death Alison pulled through and made a miraculous recovery.

Morgan was successful in having the “do not resuscitate order” dropped and claims he is now his sister’s medical proxy.

In a third video taken on September 23, 2015 and viewed by Daily Mail Online, Alison is lucid as she is interviewed by a member of the staff of a New York hospital. She clearing states her name, date of birth and names Morgan Carey as her health care proxy. She also confirms that she wants  the DNR be removed from her file.

Morgan said: ‘She is alive and is out of hospital, which is very positive.

‘But she is being scheduled for surgery on her spine and she has faces more surgery on her brain, which is going to be tough.

‘She’s also going to drug addiction meetings and visiting with her sponsor which is good. 

Morgan said in the past 12 months, following the alleged attack by a home invader at her New York home in April last year, Alison had several brain surgeries, an operation on her spleen, a hip replacement and periods of physical rehabilitation.

‘She was a train wreck,’ Morgan recalls. ‘And right now she’s on several different medications to keep her seizures under control, she’s fallen down several times and had bad injuries to her head because of her seizures.

‘She also taking her HIV meds and anti-inflammatory meds and whatever else she’s on. So yes she’s on the mend, but still needs a lot of help.’

The biggest problem, Morgan says, is the mounting medical bills.

He says he’d love to be able to pay them but he can’t afford to cover them all.

‘It’s been a constant battle, the insurance would run out, the Medicare would run out, we are always fighting that fight to just get these bills paid by Medicare,’ he said.

Alison has four children, the youngest is 14, but while they have tried to help Morgan says they have always had a difficult relationship with their mother due to her drug addiction and prostitution past.

Alison revealed she worked as a prostitute in New York as a young woman to clothe and feed her family before Mariah found fame.

He said: ‘It has to be real hard growing up knowing your mother is an addict and a prostitute, I can’t even imagine putting myself in their shoes.

‘But Alison did the best she could for her kids, was her best great, no, but she did the best she could.’

Morgan says Alison inherited $1.6million from her father Alfred Carey, when he died in 2002, and she set up trust funds for her children.

The rest of the money she has squandered on her drug addiction.

He says he understands that Mariah - who hasn’t spoken to her sister properly since they had a huge argument in 1994 - may not want to hand money to a drug addict through fear it will simply enable her.

But he adds: ‘Look me personally I’m not going to hand my sister Alison a penny directly, but if I can give money to the person giving her care, I’m going to do it.

‘Is there a way of setting up a medical fund? You don’t put cash in an addict’s hands but you can make sure that their basic medical care is met, it’s that simple.

‘Mariah can easily manage this and still keep her distance.

‘If she wants to hold her grudge, then let her hold her grudge.’

He added: ‘We just want to make Alison as comfortable as possible and to enjoy some kind of quality of life, I’m trying to do my best to help her.’

Morgan plans to return to New York in May to visit his sister and check on her progress.
