Hypersomnia: an overlooked, but not overestimated, sleep disturbance in bipolar disorder.
Sleep disturbances are common across bipolar spectrum disorders. Reduced need for sleep, insomnia and hypersomnia (excessive sleep or sleepiness) are diagnostic features of illness episodes; these sleep disturbances persist into the interepisode period and are associated with functional impairment and risk for relapse.1 Few studies have investigated subtypes of sleep disturbances within bipolar spectrum disorders, and these have been limited to specific illness states (eg, depression)2 or to specific bipolar subtypes (eg, bipolar I disorder).3This cross-sectional study recruited 563 inpatient and outpatient adults with bip...

Will Too Much Sleep Make You Fat?
In last week's article, you learned exactly how not getting enough sleep (less than about 7 hours per night), can cause fat gain, muscle loss and an inability to control the appetite, along with increased risk for a host of chronic diseases such as diabetes and obesity. But the solution is definitely not to begin sleeping as much as you possibly can. Oversleeping may seem like a good idea to fight off the fat gain that can accompany undersleeping, but it's been shown that sleeping in excess of 9 hours per night can be just as damaging to your sleep cycles and your waistline as not getting enough sleep, and in this article...

Sleep and Mental Health Disorders
Sleep is essential to the maintenance of mental health. Sleep helps to regulate mood and process emotional information and experiences into memory. Insufficient sleep is associated with increased emotional reactivity and emotional disturbance. Research indicates that REM sleep may play an especially significant role in maintaining emotional well-being and psychological balance. Sleep problems occur substantially more frequently in people with psychiatric conditions than in the general population. Often, sleep and mental health disorders exist in bi-directional relationship to each other, with each condition influencing the...

Resisting SADness
This article looks at interventions that are helpful for those suffering wintertime SAD. If the darker days put you into a darker mood, there are several interrelated things you can do to help yourself: Bundle up and go outside. Yes, go outside where it may be cold and windy. There are a number of studies that show that an hour a day of exposure to the sun’s rays do much to reduce the symptoms of SAD. Why? Because exposure to sunlight helps your body regulate the production of melatonin, the hormone that helps people sleep. More melatonin is produced when there is less sun, making you sleepy. More sun can result in ...

Kleine-Levin Syndrome May Be Misdiagnosed as Bipolar Disorder
Kleine-Levin Syndrome (KLS) is an extremely rare sleep disorder that can take years to be diagnosed. One of the possible conditions that KLS can be mistaken for is bipolar disorder, and in fact, some of the same medications used to treat bipolar disorder may be prescribed for those who have KLS. Symptoms of KLS include excessive sleeping (hypersomnia), compulsive and excessive eating (hyperphagia), childish behavior, confusion, apathy, disorientation, hallucinations and hypersexuality. Having such a difficult illness can cause depression. In addition, KLS is episodic. KLS affects mostly adolescents and 70% of patients ar...

Sleep and Bipolar Episodes - A Vicious Circle
Scientists are exploring the link between "clock" genes and bipolar disorder. For example, 2008 study found that a mutation in the core clock gene in mice produced hyperactivity and mania-like behavior. And as I wrote in Mood Disorders and Sleep, a short night can actually cause manic or hypomanic episodes. There's a lot of variance. I find that insomnia has a depressive effect on my mood, while hypersomnia (sleeping too much) is a symptom of my depression. Yet when I am hypomanic, I do have a decreased need for sleep. I am at my best when I consistently get 8 or 9 hours of restful sleep - or is it that I get 8 ...
