Periodic leg movements in sleep in essential hypertension.

The presence of periodic leg movements in sleep (PLMS) was assessed in 91 subjects diagnosed with essential hypertension. More than 18 per cent of the sample had PLMS, which is considerably higher than in normal controls. Also, the prevalence was significantly correlated with the severity of hypertension, as well as with age. Periodic leg movements in sleep were more frequent in the first few hours of the sleep period and during sleep stages 1 and 2. The arousing effect of PLMS was minimal, with only 17 per cent of all events related to an EEG arousal. Our results suggest that PLMS are common in people with essential hypertension, although they do not seem to be associated with any particular sleep disorder.

Rett's syndrome: a neurophysiological study.

Thirteen girls with Rett's syndrome were evaluated with wakefulness and sleep polygraphic records and EMG studies. The main EEG findings were paroxysmal activity during sleep, multifocal in younger and unifocal in older girls, and "pseudorhythmic flattening". In the opinion of the authors, the changes with age are related to evolution of the disease or maturational changes of CNS. The affectation of the peripheral nervous system was demonstrated in almost half the patients.

[Arousal and its influence on vigilance].

INTRODUCTION: The term arousal usually refers to transient, brief arousal during nocturnal sleep or to a state of vigilance which is maintained during the day. DEVELOPMENT AND CONCLUSION: In this review we consider the various accepted meanings and clinical disorders of 'arousal'. Insomnia (hyperarousal), parasomnias (partial arousal) and the sudden death syndrome of infancy are all attributed to disorders of arousal. It is concluded that diurnal hyperarousal leads to difficulty in getting off to sleep and staying asleep, whilst nocturnal arousal leads to excessive somnolence during the day, due to broken sleep during the night.
