Insomnia is not only unable to sleep, but also involves related problems such as frequent waking inability to sleep for hours, etc.

It may be surprising, but more than 70 types of sleep disorders affect 40 million Americans. 60% of adults report trouble sleeping a few nights a week or more and 40% suffer from excessive daytime sleepiness large enough to interfere with their normal lives. The second time is a characteristic symptom of insomnia.

It can also be caused by a combination of many factors that may have a medical supply, medical, physiological or psychological.

Cause insomnia, is the subject of extensive research, the results shed new light on why there is chaos. Anyway, we now know that conditions have much to do with the chemical imbalance in brain chemistry. Here are some highlights of some recent findings:

• New research shows that chronic insomnia may be associated with the loss of one brain to another. However, researchers are not sure about what was the first loss of the gray mater or insomnia. The results of a study published in the journal Biological Psychiatry, confirms that insomnia can cause a decrease in brain density in the orbitofrontal area of ​​the brain that controls the brain's ability to make decisions to remain alert and sleep.

According Ellemarijie ALTENA, author of the study from the Netherlands Institute for Neuroscience, is now a research associate at the University of Cambridge Department of Clinical Neuroscience lower density than the brain can be a risk factor for developing insomnia.

• Another study found that adults who suffer from primary insomnia is a specific neurochemical imbalance called gamma-aminobutyric acid (GABA), which makes it harder for your brain to close at the end of the day. The study, published in the journal Sleep, says that adults who suffer from this condition for more than 6 months was 30% less GABA, a neurotransmitter that has the ability to reduce brain activity.

Although insomnia is usually the effect of health conditions, good effects, the physical or mental health of some medications, primary insomnia is a disorder in itself, is not caused by the coexistence of medical condition, which affects 25 % of the population.

The principal investigator John Winkelman of Brigham and Women's Hospital in Boston, is mentioned in the American Academy of Sleep Medicine news release that "insomnia is a manifestation of hyperarousal, a neurobiological condition."

With all the scientific evidence as a basis for answering the question: How is insomnia, which can lead us to believe that the problem is not only what we experience at night. Given the close relationship with brain function, but also affects the energy in the day, the concentrations of mood, etc.
