An adult who is compelled to nap repeatedly during the day may have excessive daytime sleepiness (EDS); however, it is important to distinguish between occasional daytime sleepiness and EDS, which is chronic. A number of tools for screening for EDS have been developed.
Hypersomnia is a pathological state characterized by a lack of alertness during the waking episodes of the day. [3] It is not to be confused with fatigue, which is a normal physiological state. [4] Daytime sleepiness appears most commonly during situations where little interaction is needed. [5]
Older adults who are excessively sleepy during the day or have significant sleep issues are at higher risk for a pre-dementia condition called motoric cognitive risk syndrome (MCR), according to a ...
Excessive daytime sleepiness, characterized by persistent sleepiness throughout the day and often a general lack of energy, even during the day after apparently adequate or even prolonged nighttime sleep. People with EDS nap repeatedly throughout the day and have strong urges to sleep while driving, working, eating, or conversing with others. [13]
This isn’t the first time that better sleep has been linked with a lower risk of dementia: A study published in October even found that people with sleep apnea are more likely to develop dementia.
The Stanford Sleepiness Scale (SSS), developed by William C. Dement and colleagues in 1972, is a one-item self-report questionnaire measuring levels of sleepiness throughout the day. The scale has been validated for adult populations [ 1 ] and is generally used to track overall alertness at each hour of the day.
It is crucial to aim for objective measures to quantify the sleepiness. A good measurement tool is the multiple sleep latency test (MSLT). It assesses the sleep onset latency during the course of one day—often from 8:00 to 16:00. [10] An average sleep onset latency of less than 5 minutes is an indication of pathological sleepiness. [11]
Autism spectrum disorder [a] (ASD), or simply autism, is a neurodevelopmental disorder "characterized by persistent deficits in social communication and social interaction across multiple contexts" and "restricted, repetitive patterns of behavior, interests, or activities". [11] Sensory abnormalities are also included in the diagnostic manuals ...
