Power of Placebos
LOS ANGELES (Ivanhoe Newswire) --
What
is it about the very act of taking a pill -- even if it contains
no medicine -- that makes some people feel better? It's commonly
called the placebo effect and researchers studying depression
have gathered some new insight into this response to treatment.
Life wasn't always a walk in the park for Janis Schonfeld. "I
would tear and cry for no reason, just driving my daughter to
school," she tells Ivanhoe.
Schonfeld was clinically depressed so she enrolled in a study
at UCLA where she received pills for her depression. She says,
"With each passing week, I just felt that I was really getting
better."
But
her pills actually contained no medicine, just sugar. Schonfeld
was part of a study designed to examine the placebo effect.
"We knew that some patients had a transient relief of
symptoms. What we didn't know was that we could
actually alter the way the brain worked," says neuropsychiatrist
Andrew Leuchter, M.D., of the UCLA Neuropsychiatric Institute.
In the eight-week study, some patients received
anti-depressants, while others got a placebo. Researchers
periodically monitored patients' brainwaves. Fifty-two percent
of those taking the medication showed improvement, but 38
percent of those taking the placebo said they felt
better, too.
What stunned researchers is that the brains of people in the
placebo group actually showed the change.
Dr.
Leuchter says, "We can't say whether people feel better because
their brain function changed, or whether their brain function
changed because they felt better."
After the study, doctors told the placebo patients they
hadn't been on medication.
Schonfeld says, "I said to him, 'I really think that you
should check your records. I really think that I was on
medication.' And he laughed."
Today, her depression is gone, and researchers have more
evidence to back up the power of suggestion.
