Methods: Twenty subjects were randomized into a Latin square design in which each subject received 1, 5, 10, and 20 minutes of sleep during an MSLT.  ...  Subjects were asked after each nap if they fell asleep. The rate of sleep detection was analyzed as a function of sleep duration.  ...  After the allotted sleep time for each nap, subjects were awakened by an experimenter and asked "Did you fall asleep?"  ...

The Revival of Active Behavioural Devices for Measuring Sleep Latency

Hannah Scott, Leon Lack
2017 SM Journal of Sleep Disorders  
Current Methods of Measuring Sleep Latency While PSG is an effective and accurate measure of what is understood to be sleep, there are many limitations of this method that make it impractical for use outside  ...  However, people often cease activity long before they actually fall asleep, thus actigraphy devices often underestimate sleep latency [7] .  ...  People may set an alarm to wake them after a pre-determined duration of time, requiring the person to Gr up SM Copyright  Scott H estimate how long it will take them to fall asleep.  ...

2017 Cleveland Clinic journal of medicine  
to fall asleep or duration of awakenings in the middle of the night.  ...  The devices tended to overestimate sleeping time, sleep efficiency, and latency to sleep onset and underestimate awake time after falling asleep.  ...  Only the AMA can update this data, and the AMA will accept a change-of-address notice only from you. Be sure your primary specialty and type of practice also are up-to-date on AMA records.  ...

Sleep-time ambulatory blood pressure as a novel therapeutic target for cardiovascular risk reduction

R C Hermida, D E Ayala, A Mojón, M H Smolensky, F Portaluppi, J R Fernández
2014 Journal of Human Hypertension  
Our findings indicate around-the-clock ABPM is a clinical necessity to accurately detect abnormal sleep-time BP and assess CVD risk, and that hypertension ought to be managed by a bedtime therapeutic strategy  ...  Bedtime versus morning-time ingestion of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, independent of drug terminal half-life, both better reduces asleep BP and normalizes  ...  A J-shaped relationship is detected between total CVD events and daytime clinic as well as awake BP mean, but only for patients of the morning-time treatment group.  ...

Behavioral insomnia in infants and young children

Eun Kyeong Kang, Seung Soo Kim
2020 Clinical and experimental pediatrics  
A comprehensive sleep history, a sleep diary/log, and the BEARS sleep screen are useful for diagnosing sleep problems in young children.  ...  Behavioral therapies for this type of insomnia include extinction, bedtime fading with positive routines, and scheduled awakening.  ...  Sleep diary information includes bedtime, time the child falls asleep, time and duration of night waking, morning waking time, and daytime nap times and durations. 8) Parents can use a sleep diary application  ...

Ramón C. Hermida, Diana E. Ayala, Artemio Mojón, José R. Fernández
2015 Diabetologia  
Most important, lowering asleep BP, a novel therapeutic target requiring ABP evaluation, could be a significant method for reducing new-onset diabetes risk.  ...  At baseline and annually (more frequently if hypertension treatment was adjusted based on ABP) thereafter, ABP and physical activity (wrist actigraphy) were simultaneously monitored for 48 h to accurately  ...  These findings support ABPM to accurately detect abnormal sleep-time BP and, beyond its documented merit for assessing CVD risk [4-6, 9, 11-19] , evaluate risk of progression to new-onset diabetes.  ...
