The quest for self-improvement is not new. Years ago, self-help books and seminars were the ragefor improved productivity, organization, and health. In recent years, consumers download a wide variety of smartphone apps to achieve better results. In fact, "hacking" one's life has become big business. And now, some people are going so far as to use electricity and a type of DIY shock therapy to improve brain functions.

This worrisome practice has people attach to the scalp what amounts to electrodes and a small battery that delivers a low-intensity electric current to specifically targeted areas of the brain. These devices are supposed to improve study and memory skills, which make them especially popular with university students around exam time. Students learn and think more quickly, and also enjoy sharper focus. These devices are also purported to improve mood, and in particular alleviate some of the symptoms of depression, too.

The idea began as a treatment for chronic illnesses like depression, but it has spread to Internet forums with detailed instructions and vigorous discussions. Companies have cashed in on the hypetoo. Although someone could develop a device with parts from the hardware store, commercially sold devices retail for $200 and more.

Unfortunately, and perhaps unsurprisingly, there are numerous risks. Self-made devices have caused burned skin, mood swings, and outbursts of anger. Some people have complained of seeing white flashes, headaches, and nausea when using these devices too, and these are but the short-term concerns. Even worse, no one knows the long-term risks, which could prove even more detrimental than a headache remedied with aspirin.

It seems there will eternally be people who seek improvement, even with the possibility of serious risk.
