The quest for self-improvement is not new. Years ago, self-help books and seminars were the popular choice to improve productivity, organization, and health. In recent years, consumers download smartphone apps for self-improvement. In fact, "hacking" one's life has become big business. And now, some people are using a DIY shock therapy to improve brain functions.

In this worrisome hack, people attach electrodes and a small battery to the scalp, and this delivers a low-intensity electric current to the brain. These devices are supposed to improve study and memory skills, which make them especially popular with university students during exams. Students learn and think more quickly, and also have better focus. These devices are also supposed to improve the mood of the user, especially with some symptoms caused by depression.

The idea began as a treatment for chronic illnesses like depression, but it has spread to Internet forums. A search turns up detailed instructions and pages of discussions. Companies have cashed in on the hype too. Although someone could make a device with parts from the hardware store, commercially sold devices sell for $200 and more.

Unfortunately and unsurprisingly, there are numerous risks. Self-made devices have caused burns, mood swings, and outbursts of anger. Some people have complained of headaches and nausea when using these devices too. Even worse, no one knows the long-term risks, which could prove extremely harmful.

It seems there will always be people who look for improvement, even with the possibility of severerisk.
