Internet addiction is like drugs: Study

London: Addiction to
the internet could cause damage to the brain similar to that by
use of alcohol and drugs, a Chinese study has said.
According to scientists, the internet addiction disorder (IAD) is
a recently recognised condition where individuals spend unhealthy
amounts of time online, Sky News reported.
Researchers said internet disrupts nerve wiring in adolescent
brains in a similar way to people exposed to cocaine and cannabis.
On being denied access to computers, people may experience
distress and withdrawal symptoms including tremors, obsessive
thoughts and involuntary typing movements of the fingers, the
study said.
Earlier research on IAD have focused on psychological assessments
rather than the impact on the human body.
The new study involved scans of the brains of 17 internet-addicted
teenagers and 16 non-addicted individuals in China.
The scientists, led by Hao Lei from the Chinese Academy of
Sciences, found in the IAD-diagnosed teenagers evidence of
disruption to "white matter" nerve fibres connecting vital parts
of the brain involved in emotions, decision making, and
self-control.
Earlier studies have shown abnormal white matter structure in
brains of people who were addicted to alcohol, cocaine and
cannabis.
