A few years ago, CBC Radio One aired a thought-provoking, 3-part series entitled “Rethinking Depression” on its program Ideas. With the help of a number of local and world-renowned experts in the field, producer Mary O’Connell explores what we know – and what we think we know – about depression and the medications we use so often to treat it. The patient and interested listener (the entire series runs for three hours) will be rewarded with some really fascinating but often not well-publicized facts about the social, commercial and political factors that are conspiring to make psychotropic medications “a $20billion per year industry worldwide” and have led the World Health Organization to predict that depression will be the second leading caused of global disability by 2020.
This series is well worth the time to listen to!
Up until the 1950s, depression affected only about 1% of the population, and that was mostly middle-aged women. Back then, the term was used almost exclusively to refer to the serious condition that left sufferers barely able to function and often suicidal. However, in 1963, when pharmaceutical giant Hoffman-La Roche introduced its minor tranquillizer Valium, huge numbers of people began to use it to address their own ‘symptoms’ of feeling blue and overwhelmed. Whereas previous psychiatric drugs had mostly been reserved for use with the seriously mentally ill, Valium was seen as something any adult could use, just to ‘take the edge off’ everyday life. In 1966, The Rolling Stones wrote about its widespread acceptance in “Mother’s little helper” and its cultural relevance grew as it increasingly found its way into popular movies and television.
A second major societal shift that further increased the appearance of higher rates of depression occurred in 1980, with the publication of the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM), the so-called ‘bible’ every North American mental health provider relies on to distinguish what is and isn’t a psychiatric condition. Political infighting between the various high-powered authors resulted in the decision to lump into a single category both the major depression that truly incapacitated its sufferers and the milder, ‘reactive depression’ that resulted when people struggled to manage difficult life events and felt distressed but were still able to go to work every day and function reasonably well. Suddenly, the size of the market for a medication that took away distress increased dramatically.
While effective as a sedative, Valium wasn’t a great option for elevating low mood and it had some undesirable side effects as well. Pharmaceutical giant Eli Lilly resolved those problems when they brought Prozac to market in 1988. Compared to Valium, Prozac was easy for physicians to prescribe and monitor, and it was easy for consumers to take. It was quickly hailed as a breakthrough and a ‘magic bullet’ for depression. Prozac worked specifically on the neurotransmitter serotonin, and the pharmaceutical industry and its marketing partners insinuated and gradually solidified the idea that depression was the result of a chemical imbalance in the brain. Even though that idea has little empirical support it is still widely held to be true. It may be that the so-called Serotonin Hypothesis of depression is more a marketing coup than a scientific fact.
Some estimate that 75% – 80% of the effects of antidepressant medications may be due to placebo, meaning that the belief that the medication is helping to reduce symptoms may be more powerful than the medication itself. Noticeable impacts on other serotonin-related systems within the body (eg, sexual function, bowel function, and attention) may give the appearance that the drug is doing something, but scientists are still actively struggling to understand what the SSRI class of medications (that includes Prozac, Paxil, Celexa, Cipralex, Luvox and Zoloft) actually do. What is not under debate is the fact that huge amounts of money are available to be made as rates of depression continue to rise and as categories of users continue to expand. According to the series, senior citizens, children and teens are in the fastest-growing group of antidepressant users in the past 10 years and manufacturers are now re-working their formulas for use with animal populations as well (see www.reconcile.com).

Cognitive Behavioural Therapy & Emotion-Focused Therapy
The goal of cognitive behaviour therapy is to help individuals become aware of the thoughts and patterns of behaviour that keep them feeling stuck. Its focus is on the ‘here-and-now’ to help relieve current symptoms and address current problems.
Emotion-Focused Therapy is an approach to couples and family issues that focuses on identifying and correcting repetitive and dysfunctional patterns that leave people feeling alone and unsupported. EFT helps members of a couple or family to remain engaged with each other in order to better communicate what each really needs from the other.
