A healthier lifestyle could banish the blues, says a new book
Dr Steve Ilardi is slim and enthusiastic, with intense eyes. The clinical psychologist is 4,400 miles away, in Kansas, and we are chatting about his new book via Skype, the online videophone service. "I've spent a lot of time pondering Skype," he says. "On the one hand it provides a degree of social connectedness. On the other, you're still essentially by yourself". But, he concludes, "a large part of the human cortex is devoted to the processing of visual information, so I guess Skype is less alienating than voice calls".
Social connectedness is important to Ilardi. In The Depression Cure, he argues that the brain mistakenly interprets the pain of depression as an infection. Thinking that isolation is needed, it sends messages to the sufferer to "crawl into a hole and wait for it all to go away". This can be disastrous because what depressed people really need is the opposite: more human contact.
Which is why social connectedness forms one-sixth of his "lifestyle based" cure for depression. The other five elements are meaningful activity (to prevent "ruminating" on negative thoughts); regular exercise; a diet rich in omega-3 fatty acids; daily exposure to sunlight; and good quality, restorative sleep.
The programme has one glaring omission: anti-depressant medication. Because according to Ilardi, the drugs simply don't work. "Meds have only around a 50% success rate," he says. "Moreover, of the people who do improve, half experience a relapse. This lowers the recovery rate to only 25%. To make matters worse, the side effects often include emotional numbing, sexual dysfunction and weight gain".
As a respected clinical psychologist and university professor, Ilardi's views are hard to dismiss. A research team at his workplace, the University of Kansas, has been testing his system – known as TLC (Therapeutic Lifestyle Change) – in clinical trials. The preliminary results show, he says, that every patient who put the full programme into practice got better.
