REM Sleep Abnormalities
REM sleep abnormalities have been implicated by doctors in a variety of psychiatric disorders, including depression, posttraumatic stress disorder, some forms of schizophrenia, and other disorders in which psychosis occurs. Special tests, called sleep electroencephalograms, record the electrical activity of the brain and the quality of sleep. From these tests, we know that in people who are depressed, NREM sleep is reduced and REM sleep is increased. Most antidepressant medications suppress REM sleep, leading some researchers to believe that REM sleep deprivation relates to an improvement in depressive symptoms. Yet Wellbutrin XL, a common antidepressant, and some older medications used to treat depression do not suppress REM sleep. Researchers are therefore still trying to determine the connection between the REM sleep mechanism and depression.
Irregular Sleep-Wake Schedule
This sleep disorder is yet another problem that many with Bipolar II experience and in large part results from a lack of lifestyle scheduling. The reverse sleep-wake cycle is usually experienced by bipolar drug abusers and/or alcoholics who stay awake all night searching for similar addicts and engaging in drug-seeking behavior, which results in sleeping the next day. This sleep disruption and irregularity make it much more difficult for the bipolar patient's physician to treat him or her with conventional medications and adjunctive cognitive therapy. In most cases, the patient needs to acknowledge the drug-seeking behavior and get involved in a recovery program such as Alcoholics Anonymous, Cocaine Anonymous, or other group. Talk therapy with a psychologist is beneficial to many patients as they seek to change destructive lifestyle habits and learn new behaviors that will help them adhere to a more normal sleep-wake schedule.Reprinted from: Bipolar II: Enhance Your Highs, Boost Your Creativity, and Escape the Cycles of Recurrent Depression - The Essential Guide to Recognize and Treat the Mood Swings of This Increasingly Common Disorder by Ronald R.
