Tai Chi Boosts Efficacy of Antidepressant Therapy in Older Adults
July 25, 2010 - Adding an abbreviated version of Tai Chi to antidepressant therapy with escitalopram improved resilience,
quality of life, and cognitive function in adults with major depression 60 years and older, according to a new research
conducted by the David Geffen School of Medicine at the University of California, Los Angeles.
"Fewer than half of elderly depressed patients respond to first-line antidepressant pharmacotherapy,"
said Helen Lavretsky, MD, when talking about her research. "There is some information in the literature about
the benefits of Tai Chi in older adults, but this relates to their balance and their physical functioning.
We wanted to see whether Tai Chi would be helpful in improving depression."
The study recruited 112 adults with major depression and treated them with 10 mg of escitalopram daily for 6 weeks.
The 70 subjects who partially responded to escitalopram continued to receive 10 mg of escitalopram per day.
In addition, they were randomly assigned to receive either 10 weeks of Tai chi Chih for 2 hours a week or to
a lecture on health education for 2 hours a week. "Tai chi Chih is a shortened form of Tai Chi that has only 20 movements and is easier to remember over the course of 10 weeks," Dr. Lavretsky explained.
Most of the patients (62%) were women, and their mean age was 70 years. The patients were evaluated for depression, anxiety, resilience, health-related quality of life, psychomotor speed, and cognition.
Both Tai Chi and health education patients showed similar improvement in the severity of depression, with mean Hamilton Rating Scale for Depression scores of 6.0 in both groups, Dr. Lavretsky reported. However, subjects in the Tai Chi group showed significantly greater improvement in resilience than did subjects in the health education group.
The Tai Chi group also had better health-related quality of life. "Patients who were in the Tai Chi arm had a greater resilience to stress, and I thought the improvement in cognitive measures, such as memory and executive function measures, with Tai Chi was particularly impressive," Dr. Lavretsky said in an interview.
"I'm in Los Angeles, so people tend to like alternative medicine interventions," she added. "The limiting measure was the degree of arthritis that patients had. The patients who were in the education group liked that intervention, too, but it was very interesting to me to see that this gentle form of exercise had these superior results. Even C-reactive protein levels in the Tai Chi group were improved."
This study was funded by the National Center for Complementary and Alternative Medicine. It has been presented at the American Psychiatric Association's Annual Meeting in May and then at the New Clinical Drug Evaluation Unit (NCDEU) 50th Anniversary Meeting in June.
