A Very Popular Drink Is Linked To Lower IQ

A Very Popular Drink Is Linked To Lower IQ post image

The ‘refreshment’ is linked to
a slower brain and making more mistakes.
Drinking higher quantities of
alcohol and smoking cigarettes are both linked to a lower IQ, research finds.
People who smoke and drink have
a worse memory and poorer problem-solving skills.
Similarly, higher rates of
binge drinking are also linked to a lower IQ, a previous study found.
Smoking may be even more
damaging to thinking skills than drinking.
High levels of smoking and
drinking both lead to a slower brain and making more mistakes.
The reason may be that smoking
and drinking damage the blood vessels supplying the brain.
The conclusions come from a
study of 172 men, some of whom were alcoholics.
All completed tests of IQ, memory
and thinking skills and were followed up over nine years.
The results showed that the
more they drank and smoked, the lower their IQ.
Drinkers and smokers also had
worse memories and poorer thinking skills.
Jennifer Glass, the study’s first author, said:
“We can’t say that we’ve found
a cause-and-effect relationship between smoking and decreased thinking ability,
or neurocognitive proficiency. But we hope our findings of an association will
lead to further examination of this important issue. Perhaps it will help give
smokers one more reason to quit, and encourage quitting smoking among those who
are also trying to control their drinking.”
Robert Zucker, study co-author, said:
“The exact mechanism for
smoking’s impact on the brain’s higher functions is still unclear, but may
involve both neurochemical effects and damage to the blood vessels that supply
the brain. This is consistent with other findings that people with
cardiovascular disease and lung disease tend to have reduced neurocognitive
The study was published in the
journal  (Glass et al., 2006).
