LONDON — A little Beethoven is good for the
brain, according to a Finnish study published on Wednesday
showing that music helps people recover more quickly from
strokes.
And patients who listened to a few hours of
music each day soon after a stroke also improved their verbal
memory and were in a better mood compared to patients who did
not listen to music or used audio books, the researchers said.
Music therapy has long been used in a range
of treatments but the study published in the journal Brain is
the first to show the effect in people, they added.
"These findings demonstrate for the first
time that music listening during the early post-stroke stage can
enhance cognitive recovery and prevent negative mood," the
researchers wrote.
Strokes, which occur when blood flow to the
brain is blocked, can kill brain tissue and are one of the
worldwide leading causes of death and permanent disability.
Treatments include blood thinning drugs and attempts to lower
cholesterol.
The study involved 60 people who recently had
a stroke of the middle cerebral artery in the left or right side
of the brain. This is the most common stroke and can affect
motor control, speech and a range of other cognitive functions.
One group listened to their favorite music
every day or used audio books while another did not listen to
any music. All volunteers received standard rehabilitation
treatment.
Three months after stroke music listeners
showed a 60 percent better improvement in verbal memory compared
to an 18 percent benefit for those using audio books and 29
percent for people who did not listen to either.
The ability to focus attention also improved
by 17 percent in music listeners, said Teppo Sarkamo, a
psychologist at the cognitive brain Research Unit at the
University of Helsinki, who led the study.
"We can’t say what is happening in the brain
but based on previous research and theory it may be music
listening could actually activate the brain areas that are
recovering," he said in a telephone interview.
Music might also in some way activate more
general mechanisms that repair and renew the brain’s neural
networks after stroke, Sarkamo said.
Larger studies are needed to better
understand exactly what is going on but these findings show that
music may offer a cheap, easy additional treatment for stroke
patients, he said.
"This could be considered a pilot study," Sarkamo said. "It
is a promising start. —Reuters
