A daily dose of one’s favorite music can speed recovery from
a stroke, according to a study published Wednesday.
Music therapy has long been used in a range of treatments,
including autism, schizophrenia, and dementia, but the new study is the first
to show the effect in people.
“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.
Researchers at the University of Helsinki
experimented music therapy on a group of 60 patients aged 75 or younger, who
were currently in the recovery phase from either a left or right hemisphere
cerebral artery stroke.
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 participants in the study were divided into three groups
depending on how they spent the first week after their stroke, identified as
the ideal recovery period. They were listening to music, listening to audio
books, or doing nothing.
The patients were checked and tested after three months, and
then after six months.
Three months after a stroke, the researchers discovered that
verbal memory was boosted by 60 percent in music listeners, by 18 percent in
audio book listeners, and by 29 percent in non-listeners, Teppo Sarkamo, a
neuroscientist at Helsinki
University and lead
author of the study said.
“Everyday music listening during early stroke recovery offers a valuable
addition to the patients' care, especially if other active forms of
rehabilitation are not yet feasible," Sarkamo told AFP.
The ability to focus attention (the ability to control and
perform mental operations and resolve conflicts) also improved by 17 percent in
music listeners, said Sarkamo. The findings also show that those who listened
to music were less depressed and confused.
The same results were observed six months after the stroke.
“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,” Sarkamo noted.
However, larger studies are needed to exactly understand what
is going on. If validated, the study points to an easy and cost-effective
therapy for recovering stroke patients.
“Stroke patients typically spend about three-quarters of
their time each day in non-therapeutic activities, mostly in their rooms,
inactive and without interaction,” Sarkamo said.
Dr. Isabel Lee, research liaison officer at the Stroke
Association, welcomed the results of the study, but she added that “further
research into the effect of music on stroke patients need to be undertaken
before any widespread use, as presently the mechanism of any effect remains
unclear,” BBC quoted her.
The findings were published in the Oxford University Press journal Brain.
