Key points • Expressed by the physiological phasic events of NREM sleep, including arousals, cyclic alternating pattern represents the most complex arrangement of sleep microstructure. • Cyclic alternating pattern is organized in sequences organized in successive cycles. Each cyclic alternating pattern cycle is composed of a phase A (phasic events) and a phase B (background rhythm). • Cyclic al...

Background: Mothers in the postpartum period experiences a change in sleep pattern and loss of sleep duration. In the meantime, factors can cause irregular sleep patterns and decreased sleep quality. Objectives: The aim of this study was investigating the factors of fertility, anxiety and physical activity on the sleep quality of the lactating women visiting healthcare centers in Zanjan, Iran....

Mothers of 10,085 young children completed the Brief Infant/Child Sleep Questionnaire and the Pittsburgh Sleep Quality Index. Overall, there were significant relationships between maternal and child sleep for bedtime, waketime, number...

Research in younger adults suggests sleep discrepancy (objective/subjective measurement difference) is a consistent pattern that primarily occurs within individuals with insomnia. To examine whether older adults exhibit a similar pattern, this study compared night-to-night inconsistency in sleep discrepancy between older adults with and without sleep complaints. Older adults (N = 103; mean age ...

OBJECTIVE Focal cortical dysplasia (FCD) is able to generate an intrinsic pathological EEG activity characterized by a continuous or near-continuous spiking. Different patterns of discharge were described. We examined quantitatively the distribution of the intracerebral FCD patterns in relation to sleep in order to investigate whether this activity is independent of thalamocortical influences. ...
