Apparently GABA deficiency plays a role in causing sleepwalking. In an article in “Scientific American” it was reported that neurologist Antonio Oliviero and his team proposed a possible physiological mechanism underlying sleepwalking. In the article Oliviero stated the following—-“During normal sleep the chemical messenger gamma-aminobutyric acid (GABA) acts as an inhibitor that stifles the activity of the brain’s motor system. In children the neurons that release this neurotransmitter are still developing and have not yet fully established a network of connections to keep motor activity under control. As a result, many kids have insufficient amounts of GABA, leaving their motor neurons capable of commanding the body to move even during sleep. In some, this inhibitory system may remain underdeveloped—or be rendered less effective by environmental factors—and sleepwalking can persist into adulthood.” So basically what this is saying is that lack of GABA can result in sleepwalking. This is interesting work done by Antonio Oliviero and his team. Based on reading this, it’s just an opinion—I think maybe it looks like consuming GABA might be something that could be done to reduce or prevent sleepwalking. Biggest question is what dosage of GABA a person should take to prevent the sleepwalking?
More research needs to be done. But certaintly it does appear that having sufficient GABA in the brain is important in reducing and preventing sleepwalking. That’s what it appears.
