Depression is real. More than 25 million Americans suffer from it. Less than half of people suffering from depression, are seeking help. Depression can affect people of all ages, ethnicity and income bracket. Many suffer in silence, discouraged, hopelessly waiting for a miracle and a cure. Why? Because many people don't know whom to trust in choosing various treatment choices. Fortunately, there are many good ways to treat depression, even when severe. We should not close our minds and reject any available option. One of them is the antidepressants. This is the topic of a new article stirring a hot debate in the media. If you are depressed and looking for answers about the treatment for depression, do not discourage. Read both sides of the antidepressants debate.The work of Irving Kirsch, Ph.D. in psychology, is the basis of an article, The Depressing News About Antidepressants, written by Sharon Begley and published in Newsweek Magazine, on February 8, 2010. Kirsch claims that, according to his statistical analysis of 38 research studies regarding the efficacy of antidepressants, they do not work much better than a placebo in the treatment of depression; therefore, they are an unwarranted way of treating depression.
The placebo effect is the mental effect of experiencing something only because we believe in it--a mental trick, if you will, that our complex minds play on us sometimes. For example, when depressed patients are given a “sugar pill” and are told that it is an antidepressant that will help them with their depression, the symptoms of depression get better based only on the person’s belief and not because of an actual effect of a chemical substance like medication. This is what Dr. Kirsch believes accounts for the beneficial effects of antidepressants.

Bias is an attitude that always favors one particular way of feeling, acting or thinking without considering other aspects of an issue. In other words, a subjective interpretation of reality--another type of mind trick that our minds play on us, making us blind to data or information or aspects of reality that are not in accordance with what we want to believe. The placebo effect and bias are produced unconsciously by our minds. If we become aware of them when they happen, they become a free choice.
Was Kirsch biased and therefore unconsciously trying to prove once again his theory that the placebo effect is the true basis of antidepressants when he meta-analyzed the data from the 38 research studies done by others?
Meta-analysis is a statistical process that combines the results of several studies addressing a set of related research hypotheses. The advantage of it is that it can draw general conclusions from the studies. But a big disadvantage of it is the fact that it leaves ample room for bias. Meta-analysis relies heavily on studies done and published by somebody else, under his own set of biased circumstances. The decision to include or to exclude certain studies from the meta-analysis is also highly subjective, as is the chosen scope of a specific meta-analysis. In medicine, these drawbacks are so significant that the results cannot be regarded, by themselves, as the definitive conclusion of a scientific debate, because meta-analysis leaves too much room for the bias and error of the researcher.
The conclusion of the article that antidepressants are not much more effective than a placebo, and therefore their use not justified, is the result of a second attempt of Kirsch to prove his point. His first attempt was in 1998. Both times he has used the meta-analysis statistical technique of taking research data and crunching them in a certain way. Is it possible that Kirsch may have wanted to prove that he was right all along since 1998 about this subject?
Kirsch is also known for his research on the placebo effect and expectancy theory. According to this theory, people’s experience depends partly on what they expect to experience. This theory has been applied to understanding not just depression but also anxiety, pain, addictions and psychogenic illnesses. Is it possible that Kirsch, the researcher who believes that the placebo effect is a very powerful element of the human psyche, has been biased by his own prior flawed research experience to attribute to the placebo effect qualities and powers that are, in reality, not quite there?
His position on depression is that it is not the result of a change in brain chemistry. Kirsch is a doctor of psychology. He is not a physician, he is not a neurobiologist, he is not a psychiatrist. And, to my knowledge, he has never been clinically depressed and tried antidepressants himself. In my opinion, he has limited expertise to make the assumption that depression is not a "real" disorder and that antidepressants don’t work any better than a placebo. Antidepressants do work. So many people can testify to that from their own experience. There is no global antidepressant conspiracy.

Patients of mine who suffer from depression are often so exhausted that rising from bed is a genuine struggle. Many think their lives are not worth living, and feel incapable of having any hope that they will ever be healthy again. Does Kirsch seriously believe, as he asserts in his article Antidepressants: The Emperor's New Drugs?, that they will get better only with physical exercise, self-help books and talk therapy at this point? Maybe not. Don’t forget prescriptions for “sugar-pill” placebos.
Unfortunately, while in crisis, the person who is contemplating suicide or the person who can barely leave his bed because of depression, will not be up to considering these other interventions, much less following them. And people suffering from depression do not have to be suicidal to know they have deal with a serious problem. Being too depressed to be able to function in everyday life is enough to make people plunge into despair. Antidepressants are very helpful in these situations. When the crisis has abated some by using antidepressants, there are various other interventions that are important and helpful—even essential. But they can not be implemented and followed by a depressed person who's symptoms have not been first quieted down with antidepressants. In order for the treatment of depression to be effective, it has to address all the symptoms of depression, not just some of them. Untreated or under-treated depression can lead to long-term disability, loss of job, income, relationships and life style. Further complicating things, the majority of patients suffering from depression also meet the diagnosis criteria for other mental illnesses like anxiety, attention deficit or bipolar disorder. Their treatment will have to address these other problems as well. Their recovery process will look very different than that of people who suffer from depression alone, a minority. The subjects in the research studies that Kirsch has looked at were carefully selected patients that met specific depression symptoms criteria without additional complications and complexity, but they hardly reflect the reality that most people are confronted with in everyday life. Broaden the perspective on Kirsch’s statistical analysis and one finds a frightening oversimplification of the medical challenges presented by depression with its complications, complexities and dire consequences. His conclusions do not reflect and cannot be generalized to the vast majority of people suffering from depression.
Presenting a point of view based purely on meta-analysis (a statistical process) of others research studies, as Kirsch has done, while ignoring the complex clinical aspects of depression, is a grave mistake. It is a disservice done to real people, readers suffering from depression that need to consider the antidepressant option because their health depends on this decision. If they could benefit from the medication, but reject that option only because they have read the conclusions of Kirsch on the subject, and become more severely ill, that is a tragic consequence of a limited point of view too forcefully propagated by the media, without appropriate explanations for the layperson to clearly understand what it means, the pros and the cons.

I find Sharon Begely’s article both biased and narrow. And it is a disservice to their readership that Newsweek examines the controversy with seven pages presented on one side of the issue and a single page on the other side. What happened to the objective journalism? Shame! I expected so much better of Newsweek on such an important issue of health.It is true that antidepressants are not perfect. It is also true that they have been used inappropriately sometimes and that they do not represent a magic bullet. But they do work and represent a viable option among many others that can be used to treat depression. And yes, the pharmaceutical companies have made a lot of money selling medications, not only antidepressants, especially in this country, where there is no maximum price cap as there is in Canada for example, where the government negotiated a maximum acceptable price.
There is a well researched new study from Northwest University in December 2009, saying that the SSRIs, the serotonin reuptake inhibitors, the most common kind of antidepressants used today, not only produced a marked improvement in depression compared with a placebo, but also improved patients’ behavior and personality traits unrelated to the direct improvement of depression, including an increased ability to cope with life difficulties, to see things as they are more accurately, and to have less of a doom-and-gloom attitude.
Some people are upset about antidepressants in principle. Some are upset with them because they had a negative experience using antidepressants or other medications. Many people have their own biases and fears about this issue. Also a lot of people have false expectations of medications and are bitterly disappointed when their expectations do not come to fruition.
More and more patients expect a quick fix from medication. When I tell these patients that even if they take the pill, they will still have to change their behavior or learn how to cope with stress or remove themselves from an emotionally toxic environment, they usually look at me in amazement and say, “But I thought the medication is supposed to do that for me.”
Depression is a complex problem. There is not one magic bullet that will effectively work by itself. In my clinical experience, what works well for depression, alone or linked with other mental illnesses, is a combination of interventions that are tailored carefully and specifically to fit the needs of each individual patient. This combination can include but is not limited to, mindfulness therapy, cognitive behavioral therapy, life coaching and medication--the last only if and when deemed necessary in the clinical context.

Kirsch’s comments come at a time when there is an explosion of knowledge in the field of psychiatry, neurobiology, psychopharmachology, psychology and mental health. Psychiatrists are talking more and more about genuine and lasting recovery from mental illnesses, rather than only an improvement in symptoms. New types of psychotherapies are now used on a larger scale, like cognitive behavioral therapy, acceptance and commitment therapy, mindfulness therapy, and others. Life coaching is gaining more recognition. Western medicine is beginning to be more open to complementary medicine--herbal remedies, homeopathy, acupuncture, massage therapy, yoga, etc. Patients suffering from depression or other mental illnesses need not choose between medication or therapy, but have the option of taking advantage of both, in a balanced, harmonious way.Without trying to minimize the importance of the placebo effect, I would like to warn the readers of Kirsch that bias is also a powerful mental state and that, unconsciously, we may be inclined to read the statistics of research studies or a magazine article and register only the information that fits our beliefs. Perhaps the truth is somewhere in the middle:
· the placebo effect is real but also real is the experience of millions of patients who have benefited from the effects of antidepressants in order to heal and move forward in their lives;
· antidepressants are not the only way to treat depression; psychotherapy and other interventions are powerful and efficient treatment options;
· the competition between antidepressants and psychotherapy is an obsolete point of view; the two are not opposing but synergistic methods. Both aim to maximize patients’ healing and to enhance their quality of life and well being--whether used by themselves or in combination.
Healing from depression is possible. If you are depressed, talk to your internal medicine or your primary care doctor about it. Look for a psychiatrist. Find a psychotherapist or a counselor. Get a referral from a trusted friend or ask your insurance company for a list of mental health professionals. Do not fear the antidepressants. They have their own role in the treatment of depression. To get full benefit from them, antidepressants have to be used wisely and cautiously.
Your doctor will help you balance the pros and cons of various medical research studies with your particular situation and needs.
Your doctor will help you balance the pros and cons of various medical research studies with your particular situation and needs.
Most importantly, you need to get the treatment that is right for you. You are not a statistic or an anonymous number in one research study or another, but a human being facing specific challenges and problems. That type of individualized care you can only get by working one on one with your own doctor, who will help you make an informed decision about the treatment choices available. There is no reason why you should continue to suffer from depression, alone and unaided.
