The Function of Sleep Not Quite Explained

The Function of Sleep Not Quite Explained
We finished the last blog in mid-thought.  We were talking about REM sleep and the idea of brain plasticity- the rewiring of our brains that take place when we learn new information.   A recent study in rats showed that 4 days of REM sleep deprivation decreased the amount of new cells in the part of the brain that is associated with long-term memory, in other words they did not make those new circuits.   Another study with...

CPAP Treatment Linked To Lower Mortality In Stroke Patients With OSA
Stroke patients with obstructive sleep apnea (OSA) who undergo treatment with continuous positive airway pressure (CPAP) following their stroke may substantially reduce their risk of death, according to Spanish research to be published in the July 1 issue of the American Journal of Respiratory and Critical Care Medicine.

'Awakenings' That Occur With Popular Sleep-Aid Ambien May Be Explained By GUMC Study
Some people who take the fast-acting sleep-aid zolpidem (Ambien) have been observed walking, eating, talking on the phone and even driving while not fully awake. Many often don't remember doing any of these activities the next morning. Similarly, this drug has been shown to awaken the minimally conscious into a conscious state. A new study by Georgetown University Medical Center (GUMC) researchers may help explain why these "awakenings" occur.

Cognitive Behavioral Therapy for Insomnia
Cognitive Behavioral Therapy for Insomnia (CBT-I) is an effective treatment for most cases of primary insomnia, and for selected cases of secondary insomnia. There are a variety of behavioral and psychological treatments that comprise CBT-I, including stimulus control therapy, relaxation training, biofeedback, paradoxical intention, sleep restriction therapy, sleep hygiene education, and cognitive therapy. Usually several of these treatments are...

The Basics of CPAP
 Continuous Positive Airway Pressure (CPAP) is the most common treatment for obstructive sleep apnea (OSA). Except for tracheotomy, it is also the most effective treatment for OSA. CPAP is basically a computerized air pump that delivers pressurized air through a hose and then through a nasal interface into the patient's throat. The pressurized air splints open the upper airways, preventing the airflow pauses (apneas) and airflow...

Internet-Based Intervention May Improve Insomnia
An online insomnia intervention based on established face-to-face cognitive behavioral therapy techniques appears to improve patients' sleep, according to a report in the July issue of Archives of General Psychiatry, one of the JAMA/Archives journals. About one-third of adults report symptoms of insomnia and approximately 10 percent meet diagnostic criteria for an insomnia disorder, according to background information in the article.

Using Math To Take The Lag Out Of Jet Lag
Researchers at Brigham and Women's Hospital and the University of Michigan have developed a software program that prescribes a regimen for avoiding jet lag using timed light exposure. The method is described in an article published June 19 in the open-access journal PLoS Computational Biology.
