Obstructive sleep apnea (OSA), a heterogeneous and multifactorial sleep related breathing
disorder with high prevalence, is a recognized risk factor for cardiovascular morbidity and …

Background: Depression is a prevalent mental disorder that is undiagnosed and untreated
in half of all cases. Wearable activity trackers collect fine-grained sensor data characterizing …

The autonomic nervous system (ANS) is responsible for the precise regulation of tissue
functions and organs and, thus, is crucial for optimal stress reactivity, adaptive responses …

Objective We aimed to develop a machine learning algorithm to screen for depression and
assess severity based on data from wearable devices. Methods We used a wearable device …

Background: Disturbed heart dynamics in depression seriously increases mortality risk.
Heart rate variability (HRV) is a rich source of information for studying this dynamics. This …

Background Elevated night resting heart rate (HR) has been associated with increased
depression severity, yet the underlying mechanisms remain elusive. This study aimed to …

To encourage potential major depressive disorder (MDD) patients to attend diagnostic
sessions, we developed a novel MDD screening system based on sleep-induced autonomic …

Objective Depression has emerged as a global public health concern with high incidence
and disability rates, which are timely imperative to identify and intervene in clinical practice …

Objective: The purpose of this study was to develop a Falls Screening Mobile App (FallSA),
determine its acceptance, concurrent validity, test-retest reliability, discriminative ability, and …

Objective Autonomic nervous system dysfunction and reduced heart rate variability (HRV)
often co-exist with mood disorders, a phenomenon likely influenced by sleep disturbances …
