All night spectral analysis of EEG sleep in young adult and middle-aged male subjects.
The sleep EEGs of 9 young adult males (age 20-28 years) and 8 middle-aged males (42-56 years) were analyzed by visual scoring and spectral analysis. In the middle-aged subjects power density in the delta, theta and sigma frequencies were attenuated as compared to the young subjects. In both age groups power density in the delta and theta frequencies declined from NREM period 1 to 3. In the sigm...
متن کاملAge-related modifications of NREM sleep EEG: from childhood to middle age.
This study investigated the modifications in non-rapid eye movement (NREM) sleep electroencephalogram (EEG) power in 54 subjects, from children to middle-aged adults. Spectral analyses were performed on 5 h of NREM sleep. A marked decrease of absolute slow-wave activity (SWA) was observed with increasing age; children had significantly more SWA than adolescents, young and middle-aged adults. Th...

STUDY OBJECTIVES To evaluate the effects of a 25-hour sleep-deprivation episode on quantitative waking electroencephalogram (EEG) and subjective alertness in young and middle-aged subjects. DESIGN A 25-hour constant-routine protocol followed by a daytime recuperative sleep episode. SETTING Chronobiology laboratory. PARTICIPANTS Twenty-five normal subjects separated into 2 groups: young (a...

Our understanding of the mechanisms by which sleep deteriorates with age almost exclusively stems from comparisons of young and elderly subjects. The present study investigated the different effects of a 25-h sleep deprivation on the recovery sleep initiated in the morning (when circadian sleep propensity decreases) of young (20–39 y) and middle-aged subjects (40–60 y). Middle-aged subjects sho...
متن کاملAging and Sleep Stage Effects on Entropy of Electroencephalogram Signals
OF THESIS AGING AND SLEEP STAGE EFFECTS ON ENTROPY OF ELECTROENCEPHALOGRAM SIGNALS The aging brain is characterized by alteration in synaptic contacts, which leads to decline of motor and cognitive functions. These changes are reflected in the age related shifts in power spectrum of electroencephalogram (EEG) signals in both wakefulness and sleep. Various non-linear measures have been used to o...
