In addressing sleep disorders and possible solutions, there is often a lot of buzz surrounding melatonin. Research suggests that melatonin is useful in helping people to fall asleep faster (decreased sleep latency), to stay asleep longer, and to experience improved sleep quality. In order to test this, a study was conducted that compared subjects that had taken Melatonin to subjects that had taken a placebo pill in subjects with primary sleep disorders. Researchers assessed sleep onset latency, total minutes slept, and overall sleep quality in the Melatonin and placebo groups to note the differences. In the end, researchers found that melatonin decreased sleep onset latency, increased total sleep time, and improved quality of sleep significantly more than the placebo group.[49][50]


Interestingly, the glymphatic cleanrance occurs during the NREM sleep, and more specifically the NREM SWS sleep.[29][30][32] As seen previously, it is a sleep stage that decreases in normal aging.[30] So there is less glymphatic clearance and an increase in AB burden that will form the AB plaques.[32][29][30] Therefor, in AD sleep disturbances will amplify this phenomenon.

What to do: The best way to approach this issue is to try not to wake up in the first place. To do that, look at how often you're waking up and what's contributing to that. Men: Get your prostate checked, since inflammation of the prostate, benign prostatic hyperplasia (BPN), and prostate tumors can all cause this symptom. In women, frequent urination can go hand in hand with urinary issues such as incontinence , an overactive bladder, urinary tract infections, or cystitis. So see your doctor to be checked for these problems. Urinary tract problems, such as an overactive bladder, can be helped with Kegel exercises. Both men and women can learn these exercises to strengthen the muscles at the neck of the bladder.
Histamine plays a role in wakefulness in the brain. An allergic reaction over produces histamine causing wakefulness and inhibiting sleep[37] Sleep problems are common in people with allergic rhinitis. A study from the N.I.H. found that sleep is dramatically impaired by allergic symptoms and that the degree of impairment is related to the severity of those symptoms [2]s[38] Treatment of allergies has also been shown to help sleep apnea.[39]

Some of the biggest differences between the 2nd and 3rd editions are how the various sleep disorders were divided into categories. The 2005 edition used 3 broad categories to organize all of the sleep disorders under either dysommnias (disorders making getting to sleep or staying asleep difficult), parasomnias (disorders that intrude into the sleep process), and sleep disorders associated with a mental, neurologic, or other medical disorders (disorders whose symptoms are not primary unto themselves but caused by other conditions).

In the UK, knowledge of sleep medicine and possibilities for diagnosis and treatment seem to lag. Guardian.co.uk quotes the director of the Imperial College Healthcare Sleep Centre: "One problem is that there has been relatively little training in sleep medicine in this country – certainly there is no structured training for sleep physicians."[55] The Imperial College Healthcare site[56] shows attention to obstructive sleep apnea syndrome (OSA) and very few other sleep disorders. Some NHS trusts have specialist clinics for respiratory and/or neurological sleep medicine.
Stay cool at night. Make sure your bedroom is at the right temperature to help ensure a good night’s sleep. The National Sleep Foundation suggests setting the temperature between 60 and 67 degrees Fahrenheit for optimal sleep. Using cooling sheets and pillows can also help, especially for women in menopause who are experiencing hot flashes at night, says Dr. Alyssa Dweck, assistant clinical professor of obstetrics and gynecology at the Mount Sinai School of Medicine and co-author of “V is for Vagina.”
