The surnames that honor the title of this work belong to individuals fascinated by the function of sleep and its integration in neurological illness. Sleep is a function of the brain exhibiting changes with age that are predictable. There are two major manifestations of sleep alteration: somnolence and insomnia. A rich variety of sleep alterations is associated with numerous neurological disorders. Some occur acutely like in stroke whereas others appear gradually like those associated with Parkinson's disease and the dementias. The pathology of sleep is a new area of involvement in the scope of practice of the neurologist. In the future the sleep specialist will also intervene in the prevention of mental fatigue and traffic accidents and in the promotion of sleep hygiene in primary medicine.

Sleep-related complaints have become a highlight for physicians as well as public health administrators. Studies of sleep patterns and sleep-related complaints of shift workers have been useful in minimizing reduction in the quality of life due to the warping of the sleep-wake cycle. The objective of the present study was to assess patterns of sleep, sleep-related complaints as well as physical activity and scoring rates for depression and anxiety in interstate bus drivers. Data were obtained with a sleep questionnaire, with the Beck inventory for depression, and the State-Trait Anxiety Inventory (STAI). A total of 400 interstate bus drivers from the northern, southern, central-western and south-eastern regions of Brazil were interviewed. Sixty percent of the subjects interviewed presented at least one sleep-related complaint, 16% admitted to have dozed at the wheel while on duty, and 41% stated that they exercised on a regular basis. Other sleep disturbance complaints reported were: sleep latency 29'17"; physical fatigue, 59.8%; mental fatigue, 45.4%; sleepiness, 25.8%; irritability, 20.6%; insomnia, 37.5%, respiratory disturbances, 19. 25% and snoring, 20.75%. Scores for anxiety and depression were not in the pathological range. The present data reinforce the view that bus drivers are generally discontent with shift work and its effects on sleep. Consequently, it is very important to establish an appropriate work schedule for drivers, besides implementing photo-therapy and physical activities in order to minimize sleepiness when driving.

Chills can lead to problems such as insomnia, mental fatigue, and unstable emotions. Increasing evidence shows that young women, as well as menopausal women, suffer from chills. The present study investigated the effect of Piper longum L. on chills in young women. Participants with (n = 16) and without (n = 16) chills were sampled randomly from female university students using reported discriminative criteria (Yamada et al, 2007). Each participant was randomly assigned to low- (15 mg) and high-dose (30 mg) P. longum groups. We determined the severity of complaints related to chills, physical parameters (body mass index, body fat ratio, and blood pressure), the peripheral circulation dynamics using a laser tissue blood flow-meter, and the skin surface temperature in the fingers using a thermograph. Mild cold stress was applied 10 min after taking a capsule containing P. longum or a dextrin placebo. Then, a thermograph was recorded every minute for 11 min. Piper longum significantly facilitated the recovery of skin surface temperature at either low or high dosages in participants with chills. In subjects without chills, neither high- nor low-dosage of P. longum had an effect. Our findings have important implications for the utility of P. longum in women with chills.

Fatigue is a common symptom in a large number of medical and psychological disorders, including many rheumatologic illnesses. A frequent question for health care providers is related to whether reported fatigue is "in the mind" or "in the body"-that is, central or peripheral. If fatigue occurs at rest without any exertion, this suggests psychological or central origins. If patients relate their fatigue mostly to physical activities, including exercise, their symptoms can be considered peripheral. However, most syndromes of fatigue seem to depend on both peripheral and central mechanisms. Sometimes, muscle biopsy with histochemistry may be necessary for the appropriate tissue diagnosis, whereas serological tests generally provide little reliable information about the origin of muscle fatigue. Muscle function and peripheral fatigue can be quantified by contractile force and action potential measurements, whereas validated questionnaires are frequently used for assessment of mental fatigue. Fatigue is a hallmark of many rheumatologic conditions, including fibromyalgia, myalgic encephalitis/chronic fatigue syndrome, rheumatoid arthritis, systemic lupus, Sjogren's syndrome, and ankylosing spondylitis. Whereas many studies have focused on disease activity as a correlate to these patients' fatigue, it has become apparent that other factors, including negative affect and pain, are some of the most powerful predictors for fatigue. Conversely, sleep problems, including insomnia, seem to be less important for fatigue. There are several effective treatment strategies available for fatigued patients with rheumatologic disorders, including pharmacological and nonpharmacological therapies.

Fatigue is a concern for both people with insomnia and with depression, yet it remains poorly understood. Participants (N = 62) included those meeting Diagnostic and Statistical Manual of Mental Disorders (4th ed., text revision) criteria for insomnia and major depressive disorder (MDD). Multiple regression examined sleep, mood, activity, and cognitive factors as predictors of mental and physical fatigue. Only the cognitive factors (i.e., unhelpful beliefs about sleep and symptom-focused rumination) were predictive of both physical and mental fatigue. Beliefs about not being able to function and needing to avoid activities after a poor night of sleep were related to both types of fatigue. Targeting these beliefs via cognitive therapy and encouraging patients to test maladaptive beliefs about sleep may enhance fatigue response in those with MDD and insomnia.

The objective of the present study was to investigate if satisfaction of the basic needs of autonomy, competence, and relatedness is related to shift work tolerance, specifically physical and mental fatigue, insomnia, and digestive troubles in a sample of shift workers. This is a cross-sectional pilot questionnaire study, including 252 shift workers employed in a municipality in Norway. Autonomy was negatively related to physical fatigue and digestive troubles, while competence was negatively related to mental fatigue. Relatedness showed significant correlations with insomnia and mental fatigue, but did not reach significance in the regression model controlling for the two other basic needs as well as work scheduling, night work exposure, and sleep medication. Sleep medication was significant in the final regression model for insomnia, but unrelated to fatigue and digestive troubles. The demographic variables, work hours per week, work schedule, and night work exposure were unrelated to all four measures of shift work tolerance. Autonomy and competence may be more important for fatigue and digestive troubles among shift workers than work arrangement variables, night work exposure, and sleep medication use.
