Sleep Deprivation

Part 1 of this article, discussed a general approach to treating psychiatric emergencies in patients with bipolar and related disorders, as well as the assessment and management of agitation and impulsive aggression. Part 2 focuses on psychosis, suicidality, and specific treatments relevant to patients in emergency settings who are agitated or have bipolar disorder.

Methamphetamine (MA) abuse is not a new problem in the United States, but the current epidemic is more widespread and presents with more pernicious consequences than in the past. MA, frequently called "speed," "crystal," "crank," "ice," or "tina," is a potent psychostimulant that can be swallowed in pill form or administered via intranasal, intravenous, or smoking route.

Up Against the Wall

It is a widely known fact that Fyodor Dostoevsky, the famous 19th-century Russian novelist, suffered from epilepsy for most of his life. However, not too many persons are aware that Dostoevsky also had a sleep disorder called delayed sleep phase syndrome, which may have contributed to his seizures.1 Although no one knows for certain, it is quite conceivable that Dostoevsky's sleep disorder worsened his epilepsy, according to Carl Bazil, MD, PhD, director of Clinical Anticonvulsant Drug Trials and director of the Neurology Division, Columbia Comprehensive Sleep Center, Columbia University, New York.

Once again your patient, an accountant and tax specialist, is complaining about his sleep. More nights than not he awakens at about 2 am. An hour goes by, sometimes 2, before he returns to sleep. You've prescribed 4 different hypnotics. Each gave the same unsatisfactory result. For 2 weeks, your patient got the 8 hours of uninterrupted sleep he-and you-seek, but then the old pattern returned. Following your instructions, he avoids caffeine, doesn't exercise after 6 pm, and confines his activities in bed to sleep, but to no avail. You refer him to a sleep laboratory, and the results there are entirely consistent with what he's been telling you. In the sleep lab he falls asleep at 11 pm, awakens at 2:30 am, returns to sleep at 4 am, and awakens for good at 7:30 am. He does not have sleep apnea, restless legs syndrome, or depression.

It can be difficult to determine whether unusual, paroxysmal behavior represents a seizure or a nonepileptic event. Patients with convulsive, clonic movements may, in fact, be experiencing psychogenic events.

Anxiety disorders are the most prevalent psychiatric disorders in the United States. Although effective treatments are available, such as the SSRIs and cognitive-behavioral therapy (CBT), it is estimated that in about 40% of patients, anxiety disorders are partially or completely resistant to first-line treatment.

Sleep disorders are very common and are often underrecognized and underreported in children. If left untreated, these disorders can cause serious developmental and physiologic problems.

While dementia is marked by such cognitive deficits as disorientation, memory loss and changes in intellectual functioning, these are not the symptoms that cause the most distress to caregivers.

College students are far less likely to kill themselves than are nonstudent peers, according to a 10-year research study examining suicide rates at 12 Midwestern campuses.

When assessing a sleep-related problem in a psychiatric patient, investigating all possible causes may be more helpful than assuming the complaint is a result of medication or the underlying condition.

Acknowledging Preindustrial Patterns of Sleep May Revolutionize Approach to Sleep Dysfunction

Caregivers in high-pressure medical settings, such as intenstive care units (ICUs), can suffer from high levels of stress, resulting in emotional exhaustion, diminished empathy for patients, and decreased productivity.

The recent evolution of neuropsychiatry/behavioral neurology as a subspecialty represents a paradigmatic shift regarding the responsibility of psychiatrists in diagnosing and managing behavioral disorders with concomitant and demonstrable brain pathology such as dementia or head injury. This authors define the clinical usefulness of electroencephalography in evaluating neuropsychiatric disorders.

Sleep-associated movement disorders are common in the general population. When patients complain of sleep disturbance, psychiatrists should consider,and question for, features of nocturnal movement disorder.

Seasonal affective disorder affects 1% to 3% of the North American population. Evidence exists for the efficacy of high-intensity bright, fluorescent light. Pharmacological management with SSRIs has shown equivalent efficacy to light therapy. How can these two therapies be combined? What other therapies are available?

restless legs syndrome, Parkinson disease, ADHD

Delirium,Dementia

Although light therapy is an old treatment, new therapeutic uses are being researched. What is the optimal time and strength of light treatment to best help patients with depressive disorders?

As society and the definition of family in the West changes, fathers in the 21st century face emotional and psychological obstacles to a healthy parent-child relationship. This article examines professional interventions and other resources that can help prepare fathers to be effective parents.

The use of alternative treatments--like acupuncture, homeopathy, herbs, dietary supplements--for postpartum depression is becoming widespread. Dr. Hendrick discusses the benefits and risks of these alternative treatments and research that is being done to ensure their safety for new mothers

While the deaths of several students have figured prominently in recent news, studies show that college students actually have a lower rate of suicide than their nonstudent peers. What can be done to lower suicide rates even further?

College students are far less likely to kill themselves than are nonstudent peers, according to a 10-year research study examining suicide rates at 12 Midwestern campuses.

A case history illustrates the need to consider psychosocial approaches to treating postpartum depression.

As chief of the division of sleep and chronobiology in the department of psychiatry at the University of Pennsylvania School of Medicine, David F. Dinges, Ph.D., focuses on ways sleep and the endogenous circadian pacemaker interact to control wakefulness and waking neurobehavioral functions such as physiological alertness, attention, cognitive performance, fatigue, mood, neuroendocrine profiles, immune responses and health. In an interview with Psychiatric Times, Dinges discussed neurobehavioral consequences of sleep loss, factors that impair sleeping, the pervasiveness of sleepiness and new ways to manage sleepiness.

Daniel F. Kripke, M.D. has studied the relationship between biological rhythms and depression since the early 1970s. He states that seasonal responses in many mammals are controlled by the photoperiod. Therefore, it seemed that depression might be analogous to winter responses and that light might be an effective treatment.

Today, average young adults report sleeping about seven to seven and one-half hours each night. Compare this to sleep patterns in 1910, before the electric lightbulb, the average person slept nine hours each night. This means that today's population sleeps one to two hours less than people did early in the century.

Since 1980, criteria for diagnosing bipolar disorder in adults have also been used to diagnose mania in children, with some modifications to adjust for age.
