Case report: Diagnosis and intervention of a non-24-h sleep-wake disorder in a sighted child with a psychiatric disorder.

Circadian rhythm sleep-wake disorders (CRSWD) are sleep dysfunctions related to circadian functioning. They are characterized by symptoms of insomnia or excessive sleepiness that occur because the intrinsic circadian pacemaker is not entrained to a 24-h light/dark cycle. Affected individuals with a free-running disorder or hypernycthemeral syndrome (N24SWD) have a longer sleep-wake cycle that produces a sleep pattern that typically delays each day.

Application of Machine Learning Methods to Ambulatory Circadian Monitoring (ACM) for Discriminating Sleep and Circadian Disorders.

The present study proposes a classification model for the differential diagnosis of primary insomnia (PI) and delayed sleep phase disorder (DSPD), applying machine learning methods to circadian parameters obtained from ambulatory circadian monitoring (ACM). Nineteen healthy controls and 242 patients (PI = 184; DSPD = 58) were selected for a retrospective and non-interventional study from an anonymized Circadian Health Database (https://kronowizard.um.

Ambulatory circadian monitoring (ACM) based on thermometry, motor activity and body position (TAP): a comparison with polysomnography.

An integrated variable based on the combination of wrist Temperature, motor Activity and body Position (TAP) was previously developed at our laboratory to evaluate the functioning of the circadian system and sleep-wake rhythm under ambulatory conditions. However, the reliability of TAP needed to be validated with polysomnography (PSG). 22 subjects suffering from sleep disorders were monitored for one night with a temperature sensor (iButton), an actimeter (HOBO) and exploratory PSG.

[Neurocognitive and behavioral disturbances after adenotonsillectomy in obstructive sleep apnea syndrome].

Introduction: Adenotonsillectomy is an effective treatment for sleep-disordered breathing in children, but its ability to resolve neurocognitive issues, is not clear.

Objective: To analyze the outcomes of cognitive and behavioral disorders after one year of adenotonsillectomy.

Method: We studied the behavioral and cognitive abnormalities in 45 children with obstructive sleep apnea and 30 healthy controls, aged 3 to 13 years.

Clinical and polysomnographic correlation in sleep-related breathing disorders in children.

Introduction: Although polysomnography is the gold standard test for sleep-disordered breathing in children, there is controversy about its indication in all cases. Among the arguments both for and against is the lack of correlation between objective values and the symptoms.

Objective: To evaluate the correlation between clinical data and apnea-hypopnoea index (AHI) in our work environment.
