Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation

open access: yesAdvanced Science, EarlyView.
Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides

Help‐Seeking and Substance Use Among Police Staff After the 2018 Strasbourg Christmas Market Attack

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Background The use of mental health services by police staff is usually low. After the 2018 attack on the Strasbourg Christmas market, police officers exposed to psychotraumatic risks were found to have a higher PTSD risk. This study aims to describe the help‐seeking and substance use by police staff after the attack.

Clinical, Behavioral and Neuroradiological Phenotype in an Italian Cohort of Patients With Xia Gibbs Syndrome: A Multicenter Cross‐Sectional Study and Systematic Literature Review

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous variants in the AHDC1 gene are associated with Xia Gibbs Syndrome (XGS), a genetic disorder with a highly variable phenotype. Cognitive impairment, motor delay, language delay, neonatal hypotonia, and sleep apnea are considered “cardinal” signs of the disease.

Melatonin Levels in 89 Individuals With Smith Magenis Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT In patients with Smith–Magenis syndrome (SMS), an inverted circadian rhythm of melatonin (MT) contributes to the sleep disturbance. Standard treatment of sleep disturbance with MT often leads to extremely high daytime MT levels, resulting in even more sleep disorders. We therefore retrospectively evaluated the MT data of 89 SMS patients.

Distinct Neuropsychiatric Profiles Associated With 17p11.2 Deletions and RAI1 Variants in Smith–Magenis Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Smith–Magenis syndrome (SMS) results from either a recurrent 17p11.2 deletion or pathogenic variants in the retinoic acid induced 1 gene (RAI1). While neurodevelopmental impairment and behavioral dysregulation are well recognized, systematic genotype‐stratified analyses across psychiatric domains remain limited.

Sleep Disturbances in Adults With Tuberous Sclerosis Complex: Influences of Treatment and Clinical Features

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Tuberous sclerosis complex (TSC) is a genetic condition with multisystem neurocutaneous signs, including hamartomas, epilepsy, and neuropsychological difficulties. Although sleep disorders are increasingly recognized in TSC, they remain poorly described in adults.

The added value of dim light melatonin onset in diagnosing idiopathic delayed sleep phase disorder

open access: yesSleep Science, 2011
Delayed sleep phase disorder (DSPD) is characterized by delayed sleep-wake rhythm and is associated with a delayed melatonin secretion. The diagnosis of DSPD is based on clinical history, supported by actigraphy monitoring and sleep diary.

Frequency‐ and Network‐Specific Changes in Functional Connectivity Reflect Pathophysiological Mechanisms across Parkinson's Disease Stages

open access: yesAnnals of Neurology, EarlyView.
Objective Parkinson's disease (PD) is increasingly conceptualized as a disorder of large‐scale brain networks, yet whether and how frequency‐specific functional connectivity reorganizes across stages remains poorly understood. In this study, we used high‐density electroencephalography (EEG) to characterize cortico‐cortical functional connectivity ...
