The heartbroken parents of a young Dundee man have paid tribute to their son after he died from the same mysterious condition that killed his sister.
Sean Euan Lawson, 21, of Provost Road, went to his bed last Monday and never woke again.
Doctors say Sean, called Euan by his family, was a victim of Sudden Death Syndrome (SDS), the same condition that his sister Moira, 20, died from almost 10 years ago.
His mum and dad, Mariette and Andrew Lawson, are in shock at the repeat tragedy and Sean’s remaining sibling Rhona has been left devastated at the loss of her younger brother, who was hoping to start a career in the RAF.
Tesco lorry driver Andrew, 60, said: “He had his whole life ahead of him and then he goes to bed one night and that’s it, he never wakes up again it’s heartbreaking.
“He had lots of friends, his sense of humour was fantastic and he cared for people. It doesn’t seem fair.”
Although doctors have confirmed Sean’s passing is due to SDS, they have been unable to find an exact cause.
As the mystery surrounding his death continues, Sean’s family are increasingly desperate to gain closure following a decade of agony since Moira’s death from the same condition in December 2004.
Andrew said: “For us to lose two children and not know why either of them died makes it twice as heartbreaking.
“Our problem is that there’s no closure. We don’t know how our children died.
“If they die in a car crash, it’s final, you know what happened and why they died, but for us, we’re just left in the dark.”
The family all had tests after Moira’s death to find out if there was a gene or underlying reason that caused her passing, but nothing was found.
Andrew said: “Euan was fit. In fact they were both fit young people. Euan wasn’t a big drinker. I think he was only ever drunk once and he was so sick afterwards that he vowed never to do it again.
“We’ve been asking the same questions now as we have been for the last 10 years. Why have our children died?”
The family will once again be put through a number of extensive tests by doctors to find any factors that may reveal a cause.
But Andrew isn’t expecting to receive an answer and is urging the NHS to invest more money into SDS research. He said: “There’s now one new test since Moira died and that’s for something called sleep apnea, so who knows, maybe they’ll find a problem with that in our genes, but we aren’t very hopeful.
“These sudden deaths seem to be happening more and more and at some point scientists are going to have to spend some time and money to try to find out what is wrong in these cases.
“It’s tragic for us, but also lots of other people with similar experiences.”Syndrome strikes most often when asleepSudden Death Syndrome (SDS) is an umbrella term used for many different causes of cardiac arrest in young people, often during sleep.
The most common causes of unexpected sudden death in those aged 35 and younger include the thickening or abnormal structure of the heart muscle and irregularities of the electrical impulses that upset the natural rhythm of the heart.
SDS events are non-traumatic, non-violent and unexpected occurrences resulting from cardiac arrest.
There are a number of superstitions about the cause of SDS one involving eating high levels of carbohydrates just before sleep.
