(28-01-13) Art and meditation reduce stress in cancer patients

by David Gutierrez, staff writer

(NaturalNews) It has been well established that stress and anxiety hamper
healing and lead to worse outcomes in people with chronic diseases such as
cancer. Now, a new study conducted by researchers from the Jefferson-Myrna
Brind Center of Integrative Medicine and published in the journal Stress and
Health, shows that a program focusing on mindfulness meditation and expressive
art can actually produce changes in the brain leading to lower stress levels.

Although the researchers had previously studied the effects of Mindfulness-
based Art Therapy (MBAT) on stress and quality of life on cancer patients, the
new study was the first time anyone had looked at the physiological effects of
the therapy.

"Our goal was to observe possible mechanisms for the observed psychosocial
effects of MBAT by evaluating the cerebral blood flow changes associated with
an MBAT intervention in comparison with a control of equal time and attention,"
said lead author Daniel Monti.

MBAT causes changes in the brain
The study was performed on 18 people who had been diagnosed with breast cancer
between six months and three years prior to the start of the study, and who
were not currently receiving any treatment for the disease. Participants were
randomly assigned to either to a control group, consisting of an education
program, or to an MBAT group.

The MBAT therapy consisted of two parts. The first part, Mindfulness-based
Stress Reduction (MBSR), included courses in awareness of breathing, awareness
of emotion, and mindful eating, listening, walking and yoga. The second
component consisted of art activities designed to give participants the ability
to express themselves - particularly their emotions - in a meaningful way, as
well as to improve their self-regulation and coping abilities.

All participants answered a 90-question symptom checklist at both the
beginning and end of the eight-week study. Researchers also took functional
magnetic resonance imaging (fMRI) scans of the participants while at rest,
while performing a neutral task, while meditating, while performing a stressful
task, and then at rest again. These scans allowed the researchers to get a
picture of cerebral blood flow in response to various activities.

Participants who underwent MBAT therapy scored significantly lower on anxiety
tests than participants in the control group. They also showed significantly
more blood flow to the brain's emotional centers, including the left insula,
which plays a role in the perception of emotions, the amygdala, which regulates
the experience of stress, the hippocampus, which regulates the physiological
stress response, and the caudate nucleus, associated with the experience of
rewards.

The observed changes in cerebral blood flow help explain prior findings that
MBSR therapy can significantly reduce anxiety, depression and other forms of
psychological distress.

In women with breast cancer, reduction in psychological distress is
significantly correlated with improved immune function, as well as higher
quality of life and more effective coping.

"With the sample size enlarged, perhaps we can extrapolate these results to
other disease populations and gain a fuller understanding of the physiological
mechanisms by which mindfulness practices confer psychological benefits," Monti
said.
