"Powerful magnetic pulses applied to the scalp to stimulate the brain can bring fast relief to many severely depressed patients for whom standard treatments have failed. Yet it's been a mystery exactly how transcranial magnetic stimulation, as the treatment is known, changes the brain to dissipate depression. Now, research led by Stanford Medicine scientists has found that the treatment works by reversing the direction of abnormal brain signals."
"When they analyzed fMRI data across the whole brain, one connection stood out. In the normal brain, the anterior insula, a region that integrates bodily sensations, sends signals to a region that governs emotions, the anterior cingulate cortex.
"You could think of it as the anterior cingulate cortex receiving this information about the body—like heart rate or temperature—and then deciding how to feel on the basis of all these signals," Mitra said.
In three-quarters of the participants with depression, however, the typical flow of activity was reversed: The anterior cingulate cortex sent signals to the anterior insula. The more severe the depression, the higher the proportion of signals that traveled the wrong way."
"When depressed patients were treated with SNT, the flow of neural activity shifted to the normal direction within a week, coinciding with a lifting of their depression."

"To the surprise of many people, electroconvulsive therapy (ECT) is still being administered to approximately a million people a year internationally, predominantly women and old people. It involves passing enough electric current through the human brain, eight to twelve times, to cause convulsions, in the hope of somehow alleviating emotional suffering, primarily depression.
Our recent review reported that there have only ever been 11 placebo-controlled studies (where general anaesthesia is administered but the electric shock is withheld). All 11 were pre-1986, had very small sample sizes, and were seriously flawed. Four found ECT produced better outcomes for some patients in the short-term, five found no difference between the two groups at the end of treatment, and two produced mixed results, including one where psychiatrists’ ratings produced a difference, but the ratings of nurses and patients did not.
No studies have found any evidence that ECT is better than placebo beyond the end of treatment. Nevertheless, all five meta-analyses relying on these studies have concluded that ECT is more effective than placebo, despite the studies’ multiple failings. Meanwhile evidence of persistent or permanent memory loss in 12% to 55% of patients has accumulated.
... I am not the first to wonder how such highly educated and well-intentioned people can defend an obviously dangerous procedure in the absence of any robust evidence of efficacy or safety, and, moreover, why some of them do it so vehemently.
A partial explanation, perhaps, comes from Professor Leon Festinger: He developed his theory of cognitive dissonance after closely observing a cult whose leader had received messages from another planet that a flood would destroy the earth on December 21, 1954. Many members quit jobs and discarded possessions in preparation. When doomsday came and went, some cult members acknowledged they had got it wrong, but the most committed adhered to their beliefs even more strongly (Festinger et al., 1956). ... Or, in the words of Professor Paul Simon (1965), ‘A man hears what he wants to hear and disregards the rest.’"
In general, most of drug-based psychiatry also suffers from the same lack of evidence, like Marcia Angell says here:

"The problems I've discussed are not limited to psychiatry, although they reach their most florid form there. Similar conflicts of interest and biases exist in virtually every field of medicine, particularly those that rely heavily on drugs or devices. It is simply no longer possible to believe much of the clinical research that is published, or to rely on the judgment of trusted physicians or authoritative medical guidelines. I take no pleasure in this conclusion, which I reached slowly and reluctantly over my two decades as an editor of The New England Journal of Medicine."
Or Peter Goetzsche says here:

"DEADLY PSYCHIATRY AND ORGANISED DENIAL explains in evidence-based detail why the way we currently use psychiatric drugs does far more harm than good. Professor, Doctor of Medical Science, Peter C. Gøtzsche documents that psychiatric drugs kill more than half a million people every year among those aged 65 and above in the United States and Europe. This makes psychiatric drugs the third leading cause of death, after heart disease and cancer. Gøtzsche explains that we could reduce our current usage of psychotropic drugs by 98% and at the same time improve patients' mental and physical health and survival. It can be difficult, however, to come off the drugs, as many people become dependent on them. As the withdrawal symptoms can be severe, long-lasting and even dangerous, slow tapering is usually necessary. In his book, Gøtzsche debunks the many myths that leading psychiatrists - very often on drug industry payroll - have created and nurtured over decades in order to conceal the fact that biological psychiatry has generally been a failure. Biological psychiatry sees drugs as the "solution" for virtually all problems, in marked contrast to the patients' views. Most patients don't respond to the drugs they receive but, unfortunately, the psychiatrists' frustrations over the lack of progress often lead to more diagnoses, more drugs and higher doses, harming the patients further."

"We were never designed for the sedentary, indoor, sleep-deprived, socially-isolated, fast-food-laden, frenetic pace of modern life. (Stephen Ilardi, PhD)"
"Across the industrialized modern world, clinical depression has reached epidemic proportions, despite a staggering increase in the use of antidepressant medication. In fact, depression is now the single leading cause of work-related disability for adults under 50. However, there is strong evidence that depression can be both prevented and treated through a set of straightforward changes in lifestyle. Our research has demonstrated that TLC is an effective treatment for depression, with over 70% of patients experiencing a favorable response, as measured by symptom reduction of at least 50%."
TLC focuses on exercise, sunlight & vitamin D, good nutrition with adequate omega-3s, sufficient good sleep, positive socialization, and avoiding negative ruminant thinking. In general, the worst side effects of TLC are things like moving to a healthy weight and having better overall health.
