You are the most mature of the five groups (average age 60), about half are 65 or older. As a sleep savvy senior, you get the most sleep of any group, averaging 7.3 hours/night compared to 6.8 overall. You can say you get a good night’s sleep on most nights, often take two or more naps during the week, and never/rarely feel tired/fatigued. In healthy adults, sleep typically begins with NREM sleep. The pattern of clear rhythmic alpha activity associated with wakefulness gives way to N1, the first stage of sleep, which is defined by a low-voltage, mixed-frequency pattern. The transition from wakefulness to N1 occurs seconds to minutes after the start of the slow eye movements seen when a person first begins to nod off.
2. For sleep disorders, categorize as hypersomnia, insomnia, parasomnia; for each disorder describe major clinical and physiological characteristics, and mechanisms if known. NORMAL SLEEP PATTERNS Introduction: In the normal adult there are two main stages of . The particular sleep architecture of an individual over the course of an average night – the overall sleep time, the structure and pattern of sleep stages and phases, the time spent in non-REM and REM sleep, the timing and organization of sleep cycles, etc – is best illustrated by means of a hypnogram (see example below), a simplified.
Which statement is the best description of the sleep pattern for a normal adult? A) Sleep is an unconscious state in which an individual's reaction to environmental stimuli is decreased. B) Most of the sleep cycle is made up of rapid eye movement (REM) sleep. An adult has four to six sleep cycles, each with NREM sleep and REM sleep during a normal night's sleep. About every 90 minutes, REM sleep recurs. When a sleeper awakens at any stage of the sleep cycle, the cycle must start again at Stage I.
