Most Popular Depression Drugs Don't Work
Over a decade ago, a group of psychologists from England reviewed data on 47 clinical trials of people taking the six most widely prescribed antidepressants approved between 1987 and 1999. Five of these were selective serotonin reuptake inhibitors (SSRIs). The first of them to be introduced was fluoxetine – more familiar by its brand name Prozac. Introduced in 1986, it became such a sensation it gave rise to a novel called Prozac Nation and a non-fiction book called Listening to Prozac, in which the author seemed to think the drug was the best thing since the invention of the wheel. Now there are many SSRIs. They all increase levels of the mood-controlling chemical serotonin in the brain. The group of English psychologists concluded these drugs don’t benefit most patients very much. It seems they only help people with the severest symptoms, and even then the benefit is only due, they write, "to a decrease in responsiveness to placebo, rather than an increase in responsiveness to medication." In other words, in these trials a control group of severely depressed people on placebo reported less benefit than did mildly depressed people on placebo. (Makes sense – an imaginary drug is more likely to be helpful if there really isn’t much wrong with you.) But among people who were actually getting an SSRI, there was no difference in response between the mildly and severely depressed. And in both groups the benefit was small. Lead researcher Professor Irving Kirsch said, "Given these results, there seems little reason to prescribe anti-depressant medication to any but the most severely depressed patients." Prof. Kirsch’s advice was not heeded. Over the next ten years the number of prescriptions written for antidepressants in England doubled. If these drugs weren't harmful, it wouldn't be such a concern. But as Dr. Darrell Mousseau, a Professor with the Department of Psychiatry at the University of Saskatchewan, found out, they're not entirely safe.Dementia Link is "Biologically Plausible"
To see if antidepressant use is tied in with cognitive impairment or dementia, Dr. Mousseau and his colleagues checked over 4000 articles before finding just five trials that met their exacting standards. Even so, these included more than 1.5 million people. The studies encompassed people taking a number of different types of antidepressant, not just SSRIs. The researchers found that taking antidepressant drugs more than doubled the risk of either cognitive decline or dementia, including Alzheimer's. For those aged under 65 the risk tripled. The strongest risk was for those taking SSRIs. The lowest, for people prescribed older types of antidepressant. I want to stress that the study can only demonstrate an association, not cause and effect. It does not identify a mechanism by which the drugs increase dementia risk. It also wasn't possible to determine either the dosage people were taking or how long they had been prescribed the drugs. But even with these limitations, the researchers say the link is "biologically plausible" and should be taken seriously.Handed Out Like Antibiotics
Canadians are among the highest users of antidepressants worldwide, and while Dr. Mousseau accepts that the drugs benefit some people, he is alarmed at the way doctors dish them out for "sadness," insomnia, pain, hot flashes and other non-depression-related problems. Even the very young and very old receive prescriptions. "They're almost becoming the antibiotic of this century," he complains. "'If you've got a disease, take an SSRI. It's going to help you in one way, shape or form.'" And we all know the problems that indiscriminate use of antibiotics has led to. The Canadian group is not the only research team to find a link between depression drugs and dementia. A similar study was published last year by scientists from Taiwan. They condensed 754 studies down to five, four of which were different from the ones included by Dr. Mousseau's team. They concluded that "antidepressant use is significantly associated with an increased risk of developing dementia. Therefore, we suggest physicians to carefully prescribe antidepressants, especially in elder patients."Get Rid of Depression without Drugs
An excellent alternative to these drugs is regular exercise. Research suggests this may be a more effective treatment for mild depression than antidepressants because it can boost levels of serotonin. On top of that, exercise induces structural and functional changes in the brain which benefit both cognitive functioning and wellbeing, and is one of the best things we can do to reduce the risk of dementia. Another option I strongly recommend is meditation. There are a variety of different methods of meditation, and myriad teachers who will show you how.- https://www.apa.org/monitor/2017/11/numbers
