Causes and Risk Factors. Diffuse esophageal spasms can be caused by disruptions or damage to the nerves that coordinate the muscles of the esophagus. In some cases, this condition can lead to. achalasia.he esophagus is a muscular tube that connects the mouth to the stomach. During swallowing, it contracts in a coordinated way to move food or liquid to the stomach. Diffuse esophageal spasm causes the esophagus to contract in an uncoordinated way. As a result, what is swallowed is not pushed down into the stomach.
Other neurons heavily involved in controlling sleep and wakefulness belong to the in the brainstem. By diffusing their neuromodulating substances throughout wide areas of the brain, the neurons in these systems act as switches that adjust the cortexâs sensitivity to sensory information.
More research is needed to determine how slow wave sleep may play a restorative role in brain function and whether preventing low blood oxygen levels may reduce the risk of dementia.. Various studies have cautioned of the negative effects of lack of quality sleep on the brain. A Temple University study found that mice who were sleep deprived showed more plaques and tangles in the brain, a hallmark of Alzheimer's, as well as memory problems, in just eight weeks.
