Depression and the inflammatory process

Most people feel down, tired and inactive when they’re injured or ill. This “sickness behavior” is caused by the activation of the body’s immune response. It’s the brain’s way of conserving energy so the body can heal.

This immune response can also occur in people with depression. This has prompted some researchers and clinicians to hypothesise that depression is actually a side effect of the inflammatory process.

But while there may be a connection between inflammation and depression, one doesn’t necessarily lead to the other. So it’s too simplistic to say depression is a physical, rather than a psychiatric, illness.

The inflammation hypothesis

University of California clinical psychologist and researcher George Slavich is one of the key recent proponents of depression as a physical illness. He hypothesises that social threats and adversity trigger the production of pro-inflammatory “cytokines”. These are messenger molecules of the immune system that play a critical role in orchestrating the host’s response to injury and infection.

This inflammatory process, Slavich argues, can initiate profound behavioral changes, including the induction of depression.

The idea that the activation of the immune response may trigger depression in some people is by no means a new one. Early descriptions of post-influenza depression appeared in the 19th century in the writings of English physician Daniel Tuke.

But it was not until the 1988 seminal paper, published by veterinarian Benjamin Hart, that the phenomenon of acute “sickness behavior” caught the interest of the scientific community.

Hart described his detailed observations of the “behavior of sick animals”. During acute infection, and in response to fever, the animals sought sleep, lost their appetite, showed a reduction in activity, grooming and social interactions, as well as showing signs of “depression”.

Just like the immune response itself, these changes reflect an evolved survival strategy that shifts priorities toward energy conservation and recovery.

Putting the theory into practice

Cytokine-induced sickness behavior has subsequently been studied as an example of communication between the immune system and the brain.

The behavioral changes during sickness resemble those associated with depression, so it didn’t take long for researchers to make a connection between the phenomenon of sickness behavior and mental disorders.

Such speculation was strengthened by research showing that depressive states can be experimentally induced by administering cytokines and other immunogenic agents (such as vaccines) that cause an inflammatory response.

Depression is frequently associated with inflammatory illnesses such as heart disease and rheumatoid arthritis. It’s also a side effect of treatment with cytokines to enhance the immune system.

Over recent decades, researchers have made progress in understanding how inflammation may impact on the activity of signalling pathways to and from the brain, as well as on the functioning of key neural systems involved in mood regulation.

But there’s not always a link

From the available evidence it’s clear, however, that not everyone who suffers from depression has evidence of inflammation. And not all people with high levels of inflammation develop depression.

Trajectories of depression depend on a complex interplay of a spectrum of additional risk and resilience factors, which may be present to varying degrees and in a different combination in any individual at different times. These factors include the person’s:

  • genetic vulnerabilities affecting the intensity of our inflammatory response
  • other medical conditions
  • acquired hyper-vigilance in the stress response systems due to early life trauma, current adversities, or physical stressors
  • coping strategies, including social support
  • health behaviors, such as sleep, diet and exercise.

Implications for treatment

In line with the notion that inflammation drives depression, some researchers have already trialled the effectiveness of anti-inflammatory therapy as a treatment for depression.

While some recipients (such as those with high levels of inflammation) showed benefit from the treatment, others without increased inflammation did not. This supports the general hypothesis.

However, in our desire to find more effective treatments for depression, we should not forget that the immune response, including inflammation, has a specific purpose. It protects us from infection, disease and injury.

Cytokines act at many different levels, and often in subtle ways, to fulfill their numerous roles in the orchestration of the immune response. Undermining their vital role could have negative consequences.

Mind versus body

The recent enthusiasm to embrace inflammation as the major culprit in psychiatric conditions ignores the reality that “depression” is not a single condition. Some depressive states, such as melancholia, are diseases; some are reactions to the environment; some are existential; and some normal.

Such separate states have differing contributions of biological, social and psychological causes. So any attempt to invoke a single all-explanatory “cause” should be rejected. Where living organisms are concerned it is almost never that simple.

In the end, we cannot escape the reality that changes must occur at the level of the brain, in regions responsible for mood regulation, for “depression” to be experienced.

Yoga Benefits

Many people hear “yoga”, and think Zen gardens, meditation, and free spirits. But you may be surprised to find that one recent study showed that those who incorporated yoga into their life had improved stress levels and lower blood pressure. Yoga was ultimately developed to combine controlled breathing and poses to achieve physical, mental, and spiritual strength and unity. In fact, Michelle Obama even attributes her sleek physique to frequent yoga sessions. There are multiple types of yoga, but Hatha Yoga is the most commonly practiced type in the United States.

Here are some surprising health benefits of practicing yoga that you may have never known!

Relief of Back Pain: More than 60 million Americans suffer from chronic back pain. Yoga is one of the best exercises to help alleviate pain. This is due to the increase in core stability (abdominal muscles) and the reduction of pressure across the lower back and surrounding muscles. Yoga also helps to release endorphins throughout the body that can calm inflammation. Practicing yoga for just two sessions a week may reduce or even eliminate back pain. Many individuals also report an increase in pain tolerance after attending sessions for only three weeks.

Heart Healthy: Further research also demonstrates that even one yoga session can produce a calming effect on the body, and individuals in one study showed reduction in their systolic blood pressure after only 12 weeks of two yoga sessions per week. Additionally, incorporating yoga into a cardiac rehabilitation program after a heart attack or bypass surgery has also shown promise in maintaining lower levels of stress and healthy blood pressure levels.

Increased Flexibility: You may be thinking, “No Duh”, on this one, but the benefits may be surprising. Practicing poses like downward dog, and tree pose can improve balance and flexibility. This can directly strengthen and protect your larger joints (knees, hips, back, neck) from injury and reduce inflammation in the smaller joints (fingers and ankles). This can also help reduce falls in the elderly, and ultimately avoid fractures in this age group.

Mood Booster: In addition to mental clarity and relaxation, yoga has been shown to improve depression, anxiety, and chronic stress. A small German study reviewed in the Harvard Mental Health Letter demonstrated that at the end of a three-month period, women perceived less stress, depression, anxiety, and fatigue. A few yoga classes could leave you happier and less stressed. Increased happiness alone is reason enough to give it a try!

As with any new exercise, always consult your physician before you begin. This is to ensure your body can safely complete the activity. I also recommend you attend a beginner class or view a video with some common poses. This will make you feel more confident during your first class and ensure you obtain the most benefit.

depression

From an article on the Yoga International web site: 5241352878_f53a343088

Anyone who has suffered from depression understands how deep, abiding sadness or worthlessness can infiltrate and affect every aspect of our being. Our psychological makeup, physical health, mental outlook, and even our ability to interact with friends and family and be present to the world around us can get shaken to their core. Why? Because we identify with and attach ourselves to things that will inevitably change. As our feelings and other symptoms of depression persist, we have an increasingly difficult time imagining a life in which we break free from their spell and avoid “becoming” them.

Yoga teaches us that we aren’t our feelings or our symptoms but live in multidimensional relationship with them. One way to grasp this paradox is to picture the Self (purusha or pure, undifferentiated awareness) as pervading all nine interlocking and interdependent spheres of influence without being any one of them.

depression

Whether you’re a college student in the middle of a major slump, a new mom who can’t pinpoint why she’s feeling so glum, or a retiree grieving over the loss of a loved one, that question isn’t an easy one to answer.21789-113979.jpg

But there’s one thing for sure: “It is much more than just a sad mood,” said Angelos Halaris, MD, a professor of psychiatry and medical director of adult psychiatry at the Loyola University Medical Center in Chicago. Symptoms may include everything from hopelessness and fatigue to physical pain. And just as symptoms vary from person to person, so do the actual diagnoses. The word depression is actually just an umbrella term for a number of different forms, from major depression to atypical depression to dysthymia.

The most common form of depression? Major depression. In fact, about 7 percent of the adult U.S. population has this debilitating mental health condition at any given time, according to the National Institute of Mental Health (NIMH).

If you’re experiencing major depression, you may feel and see symptoms of extreme sadness, hopelessness, lack of energy, irritability, trouble concentrating, changes in sleep or eating habits, feelings of guilt, physical pain, and thoughts of death or suicide — and for an official diagnosis, your symptoms must last for more than two weeks. In some instances, a person might only experience one episode of major depression, but the condition tends to recur throughout a person’s life.

The best treatment is usually with antidepressant medications, explained Dr. Halaris, but talk therapy may also be used to treat depression. And there’s good news: An estimated 80 to 90 percent of people with major depression respond well to treatment.

About 2 percent of the American population has a form of depression that’s less severe than major depression, but is still very real — dysthymia.

Dysthymia is a type of depression that causes a low mood over a long period of time — perhaps for a year or more, explained Halaris. “People can function adequately, but not optimally.” Symptoms include sadness, trouble concentrating, fatigue, and changes in sleep habits and appetite.

This depression usually responds better to talk therapy than to medications, though some studies suggest that combining medication with talk therapy may lead to the greatest improvement. People with dysthymia may also be at risk for episodes of major depression.

A whopping 85 percent of new moms feel some sadness after their baby is born — but for up to 16 percent of women, that sadness is serious enough to be diagnosable.5241352878_f53a343088.jpg

Postpartum depression is characterized by feelings of extreme sadness, fatigue, loneliness, hopelessness, suicidal thoughts, fears about hurting the baby, and feelings of disconnect from the child. It can occur anywhere from weeks to months after childbirth, and Halaris explained it most always develops within a year after a woman has given birth.

“It needs prompt and experienced medical care,” he said — and that may include a combination of talk and drug therapy.

Would you prefer to hibernate during the winter than face those cold, dreary days? Do you tend to gain weight, feel blue, and withdraw socially during the season?

You could be one of 4 to 6 percent of people in the United States estimated to have seasonal affective disorder, or SAD. Though many people find themselves in winter funks, SAD is characterized by symptoms of anxiety, increased irritability, daytime fatigue, and weight gain. This form of depression typically occurs in winter climates, likely due to the lessening of natural sunlight. “We don’t really know why some people are more sensitive to this reduction in light,” said Halaris. “But symptoms are usually mild, though they can be severe.”

This depression usually starts in early winter and lifts in the spring, and it can be treated with light therapy or artificial light treatment.

Despite its name, atypical depression is not unusual. In fact, it may be one of the most common types of depression — and some doctors even believe it is underdiagnosed.

“This type of depression is less well understood than major depression,” explained Halaris. Unlike major depression, a common sign of atypical depression is a sense of heaviness in the arms and legs — like a form of paralysis. However, a study published in the Archives of General Psychiatry (now known as JAMA Psychiatry) found that oversleeping and overeating are the two most important symptoms for diagnosing atypical depression. People with the condition may also gain weight, be irritable, and have relationship problems.

Some studies show that talk therapy works well to treat this kind of depression.

Psychosis — a mental state characterized by false beliefs, known as delusions, or false sights or sounds, known as hallucinations — doesn’t typically get associated with depression. But according to the National Alliance on Mental Illness, about 20 percent of people with depression have episodes so severe that they see or hear things that are not really there.

“People with this psychotic depression may become catatonic, not speak, or not leave their bed,” explained Halaris. Treatment may require a combination of antidepressant and antipsychotic medications. A review of 10 studies concluded that it may be best to start with an antidepressant drug alone and then add an antipsychotic drug if needed. Another review, however, found the combination of medications was more effective than either drug alone in treating psychotic depression.

If your periods of extreme lows are followed by periods of extreme highs, you could have bipolar disorder (sometimes called manic depressive disorder because symptoms can alternate between mania and depression).

Symptoms of mania include high energy, excitement, racing thoughts, and poor judgment. “Symptoms may cycle between depression and mania a few times per year or much more rapidly,” Halaris said. “This disorder affects about 2 to 3 percent of the population and has one of the highest risks for suicide.” Bipolar disorder has four basic subtypes: bipolar I (characterized by at least one manic episode); bipolar II (characterized by hypomanic episodes — which are milder — along with depression); cyclothymic disorder; and other specified bipolar and related disorder.

People with bipolar disorder are typically treated with drugs called mood stabilizers.

Premenstrual dysphoric disorder, or PMDD, is a type of depression that affects women during the second half of their menstrual cycles. Symptoms include depression, anxiety, and mood swings. Unlike premenstrual syndrome (PMS), which affects up to 85 percent of women and has milder symptoms, PMDD affects about 5 percent of women and is much more severe.

“PMDD can be severe enough to affect a woman’s relationships and her ability to function normally when symptoms are active,” said Halaris. Treatment may include a combination of depression drugs as well as talk and nutrition therapies.

Also called adjustment disorder, situational depression is triggered by a stressful or life-changing event, such as job loss, the death of a loved one, trauma — even a bad breakup.

Situational depression is about three times more common than major depression, and medications are rarely needed — that’s because it tends to clear up over time once the event has ended. However, that doesn’t mean it should be ignored: Symptoms of situational depression may include excessive sadness, worry, or nervousness, and if they don’t go away, they may become warning signs of major depression.
