year in the UK, Canada, and Australia, just to name a few countries with high numbers of drug consumption. Even more alarming is the rise of deadly antidepressant use. In the U.S., there’s been a steady increase in medication overdose deaths, from 1,749 in 1999 to 5,064 in 2018, according to the National Institute on Drug Abuse. In some cases, though, antidepressants weren’t the only cause of death as they were taken in combination with other addictive substances. In Australia, the number of people who overdosed on antidepressants more than doubled between 1999 and 2016, when 276 individuals died, accounting for 15.3 percent of all drug-induced deaths in the country, according to the Australian Bureau of Statistics. The reasons that have led to this massive use of antidepressants are a complex mix of factors. They sit at the intersection of personal values on mental health, how to deal with distress, the power of drug marketing, the influence of doctors, and gaps in therapeutic services. But some of them seem to carry undeniable weight. Firstly, the looseness of diagnostic labels around depression certainly contributes to soaring antidepressant prescriptions. According to the Diagnostic and Statistical Manual (DSM), a key reference for psychiatric diagnosis worldwide, the condition technically known as major depressive disorder (MDD) should be diagnosed when people have a depressed mood or diminished interest in almost all activities, along with at least four other symptoms like appetite or sleep disturbance, fatigue, feelings of worthlessness, decreased concentration, and recurrent suicidal thoughts for at least two weeks. This definition opens up vast diagnostic and misdiagnosis opportunities, especially in people who have gone through distressing events, like the loss of a loved one. It can be argued, for example, that a bereaved person could display signs of MDD for more than two weeks, but this doesn’t make them mentally ill. �The MDD definition works well at the severe end, but at the mild end it has led to the creeping repackaging of everyday normal unhappiness into mental disorder,” Dr Allen Frances, a psychiatrist and chairman of the task force that produced the fourth edition of the DSM, wrote in Saving Normal. “There is no way to demarcate a clean boundary between the milder forms of clinical depression and severer forms of ordinary, normal sadness.” This diagnostic difficulty extends beyond depression to the entire realm of mental disease and boils down to the lack of biological markers for mental problems. With the lack of specific characteristics that can be detected through medical examination like blood test or brain imaging, mental illnesses are diagnosed by checking a list of symptoms that a group of experts have agreed on. “The absence of biological tests is a huge disadvantage for psychiatry. It means that all of our diagnoses are now based on subjective judgments that are inherently fallible and prey to capricious change,� wrote Dr �rances, stressing that no definition of mental disorder is particularly helpful in determining who is sick and who isn’t. Coupled with the reality of general practitioners lacking time and alternatives to drugs, such diagnostic looseness has translated into a vicious circle where people get unnecessary drugs that trap them for long periods of time. “There’s nothing easier in the world than starting an antidepressant. Primary care doctors are given far too little time with their patients, and the only way they can get a patient out of the office satisfied after a sevenminute visit is to write a prescription,” Dr Frances told CNN, noting that in the U.S. general practitioners prescribe around 80 percent of antidepressants. “On the other hand, stopping the medicine can take years. It requires for some people a very, very slow taper, and without that they’ll have symptoms of return of anxiety, of depression, flu-like physical symptoms, and often they will misattribute these return of symptoms to thinking that they’re getting depressed again, when in fact it’s �ust the result of withdrawal side effects.� Even when doctors are aware of the risks, antidepressants may be the only option available. “No doctor wants their patients to be reliant on medication – and most patients don’t want this, either – so where possible we will consider alternative treatments, such as CBT and talking therapies, but unfortunately access to these important services in the community is patchy across the country,” said Professor Helen Stokes-Lampard, Chair of the UK Royal College of General Practitioners, in a statement that tried to explain why antidepressants prescriptions in England almost doubled in ten years to reach 70.9 million in 2018.
