Internet addiction has for the first time been
linked with changes in the brain similar to those seen in people addicted to
alcohol, cocaine and cannabis.
In a
groundbreaking study, researchers used MRI scanners to reveal abnormalities in
the brains of adolescents who spent many hours on the internet, to the
detriment of their social and personal lives. The finding could throw light on
other behavioural problems and lead to the development of new approaches to
treatment, researchers said.
An
estimated 5 to 10 per cent of internet users are thought to be addicted –
meaning they are unable to control their use. The majority are games players
who become so absorbed in the activity they go without food or drink for long
periods and their education, work and relationships suffer.
Henrietta
Bowden Jones, consultant psychiatrist at Imperial College, London, who runs
Britain's only NHS clinic for internet addicts and problem gamblers, said:
"The majority of people we see with serious internet addiction are gamers
– people who spend long hours in roles in various games that cause them to
disregard their obligations. I have seen people who stopped attending university
lectures, failed their degrees or their marriages broke down because they were
unable to emotionally connect with anything outside the game."
Although
most of the population was spending longer online, that was not evidence of
addiction, she said. "It is different. We are doing it because modern life
requires us to link up over the net in regard to jobs, professional and social
connections – but not in an obsessive way. When someone comes to you and says
they did not sleep last night because they spent 14 hours playing games, and it
was the same the previous night, and they tried to stop but they couldn't – you
know they have a problem. It does tend to be the gaming that catches people
out."
Researchers
in China scanned the brains of 17 adolescents diagnosed with "internet
addiction disorder" who had been referred to the Shanghai Mental Health
Centre, and compared the results with scans from 16 of their peers.
The
results showed impairment of white matter fibres in the brain connecting
regions involved in emotional processing, attention, decision making and
cognitive control. Similar changes to the white matter have been observed in
other forms of addiction to substances such as alcohol and cocaine.
"The
findings suggest that white matter integrity may serve as a potential new
treatment target in internet addiction disorder," they say in the online
journal Public Library of Science One. The authors acknowledge that they cannot
tell whether the brain changes are the cause or the consequence of the internet
addiction. It could be that young people with the brain changes observed are
more prone to becoming addicted.
Professor
Michael Farrell, director of the National Drug and Alcohol Research Centre,
University of New South Wales, Australia, said: "The limitations [of this
study] are that it is not controlled, and it's possible that illicit drugs,
alcohol or other caffeine-based stimulants might account for the changes. The
specificity of 'internet addiction disorder' is also questionable."
Case
studies: Caught in the web
Xbox
addict killed by blood clot after 12-hour sessions
Chris
Staniforth, 20, died of a blood clot after spending up to 12 hours at a time
playing on his Xbox. Despite having no history of ill health, he developed deep
vein thrombosis – commonly associated with long-haul flight passengers. Mr
Staniforth, from Sheffield, had been offered a place to study game design at
the University of Leicester. But he collapsed while telling a friend he'd been
having pains in his chest.
Toddler
starved to death while mother played online
A
mother was jailed for 25 years after her daughter starved to death while she
played an online game for hours at a time. Rebecca Colleen Christie, 28, from
New Mexico in the US, played the fantasy game World of Warcraft while her
three-year-old daughter, Brandi, starved. The toddler weighed just 23lbs when
she was finally rushed to hospital after her mother found her limp and
unconscious.
Woman
jailed after gamble fails to pay off
A
woman who stole £76,000 from a company to fund her internet gambling addiction
was jailed this week. Lucienne Mainey, 41, from Cambridgeshire, was sentenced
to 16 months in prison at Ipswich Crown Court after admitting fraud. The court
heard she secretly paid herself by changing old invoices. Mainey turned to
internet bingo following the breakdown of her marriage.
