Just a bit of reading to better understand the connection 
between Bipolar and Yoga, as a healing modality.

Partial Article From Mitch Rustad, 2008

 "Researchers from the David Geffen School of Medicine at the University of California, Los Angeles, have lauded the potential of yoga as a complementary treatment for depressed patients, noting "significant reductions" in depression, anger, anxiety, and neurotic symptoms of study participants, while concluding "yoga appears to be a promising intervention for depression."

In addition, researchers at Boston University School of Medicine (BUSM) and McLean Hospital, a psychiatric facility associated with Harvard Medical School, reported that practicing yoga may elevate brain gamma-aminobutyric (GABA) levels, the brain's primary inhibitory neurotransmitter. And they suggested that the practice of yoga be explored as a possible treatment for depression and anxiety.

Gagan Joshi, M.D., a psychiatrist at Massachusetts General Hospital who specializes in bipolar disorder, encourages yoga for his patients because it can work in partnership with their medication to stabilize moods.

"While bipolar medications are very good at taking care of mania, they are not that potent in managing anxiety and depression," says Joshi, "which is where a complementary treatment like yoga can come in.

"We have a similar dilemma with medications used for anxiety and depression because they pose a risk of triggering mania. So that's another case where complementary treatments like yoga can come into play because it can help some people reduce doses of these kinds of medication."

Jaymie Meyer, a certified yoga therapist in private practice in New York City, says one of her clients successfully reduced his antidepressant intake from 200 milligrams to only 75 milligrams — all with the blessing of his physician — during just two months of daily practice. Meyer says she "attributes his progress in reducing the dosage to his daily practice of yoga."

But when it comes to yoga as a complementary treatment for symptoms of depression, "one size definitely does not fit all," she adds.

For example, someone who's dealing with anxiety, agitation or mind racing would not be best served by a rigorous yoga session with continuous movement (such as repeated "sun salutations"). This person might be best served through simple, stationary yoga poses such as shavasana, or the "dead man's pose," in which ones lies on his back with an emphasis on breathing.

"If you're often agitated, it's helpful to focus on the exhalation, which tends to bring you into relaxation," Meyer says. "Anxious or agitated people tend to not take the time to exhale, which lowers the heart rate."

A person with the opposite symptoms (low energy, lethargy and sadness) needs to take in more air, so doing a more active form of yoga while focusing on the inhalation of the breath would be best, Meyer says. "These people, in a metaphoric sense, are not taking in life, so they need to filled up with the life force."

Most people tend to experience a combination of lethargy and anxiety, so that's why it's very important to work with professional yoga instructors — either privately or at a yoga studio, gym, school or other public facilities that offer classes, she says. 

But beyond the type of yoga and eventual setting you settle on, establishing a routine that includes familiar faces can increase any benefits, Smaller says. "If there's an ongoing yoga class, with the same instructor and maybe some of the same students, I think these relationships will also have a positive impact on a person's mood."

"Fibromyalgia patients who aren't getting relief from prescription drugs and are in too much pain to exercise may want to try yoga, a new study suggests.A weekly two-hour yoga class reduced fibromyalgia symptoms such as pain, fatigue, and stiffness by 30 percent in more than half of the people who took it, according to the study, which was published in the journal Pain. A control group of patients who continued their regular (medical)treatment regimen reported no change in symptoms."

"...the participants with fibromyalgia — as expected — perceived pain at lower pressure levels compared with the other subjects. Functional MRIs showed they also had the greatest activity in areas of the brain associated with the pain response. In contrast, the yoga practitioners had the highest pain tolerance and lowest pain-related brain activity during the MRI."

Studies suggest that this practice modulates the stress response.

Since the 1970s, meditation and other stress-reduction techniques have been studied as possible treatments for depression and anxiety. One such practice, yoga, has received less attention in the medical literature, though it has become increasingly popular in recent decades. One national survey estimated, for example, that about 7.5% of U.S. adults had tried yoga at least once, and that nearly 4% practiced yoga in the previous year.

Yoga classes can vary from gentle and accommodating to strenuous and challenging; the choice of style tends to be based on physical ability and personal preference. Hatha yoga, the most common type of yoga practiced in the United States, combines three elements: physical poses, called asanas; controlled breathing practiced in conjunction with asanas; and a short period of deep relaxation or meditation.

Many of the studies evaluating yoga's therapeutic benefits have been small and poorly designed. However, a 2004 analysis found that, in recent decades, an increasing number have been randomized controlled trials — the most rigorous standard for proving efficacy.

Available reviews of a wide range of yoga practices suggest they can reduce the impact of exaggerated stress responses and may be helpful for both anxiety and depression. In this respect, yoga functions like other self-soothing techniques, such as meditation, relaxation, exercise, or even socializing with friends.

Taming the stress response by reducing perceived stress and anxiety, yoga appears to modulate stress response systems. This, in turn, decreases physiological arousal — for example, reducing the heart rate, lowering blood pressure, and easing respiration. There is also evidence that yoga practices help increase heart rate variability, an indicator of the body's ability to respond to stress more flexibly.

A small but intriguing study further characterizes the effect of yoga on the stress response. In 2008, researchers at the University of Utah presented preliminary results from a study of varied participants' responses to pain. They note that people who have a poorly regulated response to stress are also more sensitive to pain. Their subjects were 12 experienced yoga practitioners, 14 people with fibromyalgia (a condition many researchers consider a stress-related illness that is characterized by hypersensitivity to pain), and 16 healthy volunteers.

When the three groups were subjected to more or less painful thumbnail pressure, the participants with fibromyalgia — as expected — perceived pain at lower pressure levels compared with the other subjects. Functional MRIs showed they also had the greatest activity in areas of the brain associated with the pain response. In contrast, the yoga practitioners had the highest pain tolerance and lowest pain-related brain activity during the MRI. The study underscores the value of techniques, such as yoga, that can help a person regulate their stress and, therefore, pain responses.

Improved mood and functioningQuestions remain about exactly how yoga works to improve mood, but preliminary evidence suggests its benefit is similar to that of exercise and relaxation techniques.

In a German study published in 2005, 24 women who described themselves as "emotionally distressed" took two 90-minute yoga classes a week for three months. Women in a control group maintained their normal activities and were asked not to begin an exercise or stress-reduction program during the study period.

Though not formally diagnosed with depression, all participants had experienced emotional distress for at least half of the previous 90 days. They were also one standard deviation above the population norm in scores for perceived stress (measured by the Cohen Perceived Stress Scale), anxiety (measured using the Spielberger State-Trait Anxiety Inventory), and depression (scored with the Profile of Mood States and the Center for Epidemiological Studies Depression Scale, or CES-D).

At the end of three months, women in the yoga group reported improvements in perceived stress, depression, anxiety, energy, fatigue, and well-being. Depression scores improved by 50%, anxiety scores by 30%, and overall well-being scores by 65%. Initial complaints of headaches, back pain, and poor sleep quality also resolved much more often in the yoga group than in the control group.

One uncontrolled, descriptive 2005 study examined the effects of a single yoga class for inpatients at a New Hampshire psychiatric hospital. The 113 participants included patients with bipolar disorder, major depression, and schizophrenia. After the class, average levels of tension, anxiety, depression, anger, hostility, and fatigue dropped significantly, as measured by the Profile of Mood States, a standard 65-item questionnaire that participants answered on their own before and after the class. Patients who chose to participate in additional classes experienced similar short-term positive effects.

Further controlled trials of yoga practice have demonstrated improvements in mood and quality of life for the elderly, people caring for patients with dementia, breast cancer survivors, and patients with epilepsy.

Benefits of controlled breathingA type of controlled breathing with roots in traditional yoga shows promise in providing relief for depression. The program, called Sudarshan Kriya yoga (SKY), involves several types of cyclical breathing patterns, ranging from slow and calming to rapid and stimulating, and is taught by the nonprofit Art of Living Foundation.

One study compared 30 minutes of SKY breathing, done six days a week, to bilateral electroconvulsive therapy and the tricyclic antidepressant imipramine in 45 people hospitalized for depression. After four weeks of treatment, 93% of those receiving electroconvulsive therapy, 73% of those taking imipramine, and 67% of those using the breathing technique had achieved remission.

Another study examined the effects of SKY on depressive symptoms in 60 alcohol-dependent men. After a week of a standard detoxification program at a mental health center in Bangalore, India, participants were randomly assigned to two weeks of SKY or a standard alcoholism treatment control. After the full three weeks, scores on a standard depression inventory dropped 75% in the SKY group, as compared with 60% in the standard treatment group. Levels of two stress hormones, cortisol and corticotropin, also dropped in the SKY group, but not in the control group. The authors suggest that SKY might be a beneficial treatment for depression in the early stages of recovery from alcoholism.

Potential help for PTSDSince evidence suggests that yoga can tone down maladaptive nervous system arousal, researchers are exploring whether or not yoga can be a helpful practice for patients with post-traumatic stress disorder (PTSD).

One randomized controlled study examined the effects of yoga and a breathing program in disabled Australian Vietnam veterans diagnosed with severe PTSD. The veterans were heavy daily drinkers, and all were taking at least one antidepressant. The five-day course included breathing techniques (see above), yoga asanas, education about stress reduction, and guided meditation. Participants were evaluated at the beginning of the study using the Clinician Administered PTSD Scale (CAPS), which ranks symptom severity on an 80-point scale.

Six weeks after the study began, the yoga and breathing group had dropped their CAPS scores from averages of 57 (moderate to severe symptoms) to 42 (mild to moderate). These improvements persisted at a six-month follow-up. The control group, consisting of veterans on a waiting list, showed no improvement.

About 20% of war veterans who served in Afghanistan or Iraq suffer from PTSD, according to one estimate. Experts treating this population suggest that yoga can be a useful addition to the treatment program.

Researchers at the Walter Reed Army Medical Center in Washington, D.C., are offering a yogic method of deep relaxation to veterans returning from combat in Iraq and Afghanistan. Dr. Kristie Gore, a psychologist at Walter Reed, says the military hopes that yoga-based treatments will be more acceptable to the soldiers and less stigmatizing than traditional psychotherapy. The center now uses yoga and yogic relaxation in post-deployment PTSD awareness courses, and plans to conduct a controlled trial of their effectiveness in the future.

Cautions and encouragementAlthough many forms of yoga practice are safe, some are strenuous and may not be appropriate for everyone. In particular, elderly patients or those with mobility problems may want to check first with a clinician before choosing yoga as a treatment option.

But for many patients dealing with depression, anxiety, or stress, yoga may be a very appealing way to better manage symptoms. Indeed, the scientific study of yoga demonstrates that mental and physical health are not just closely allied, but are essentially equivalent. The evidence is growing that yoga practice is a relatively low-risk, high-yield approach to improving overall health.
