AI Article Synopsis
- Polysomnography (PSG) is a key method for studying sleep behavior and functions, proving useful for diagnosing sleep disorders.
- Data shows that in 20% of insomnia cases, there’s an identifiable physical cause, like sleep apnea, which PSG can detect, contributing significant diagnostic insight in 50-75% of insomniacs.
- Case studies illustrate that even those without obvious sleep complaints may have underlying issues that PSG can reveal, suggesting broader use of this technique could enhance treatment outcomes.
Article Abstract
Polysomnography (PSG) is a standard procedure for investigating sleep functions including behavior. This technique is described. The diagnostic value of PSG is shown by statistical data from the literature and our own patient sample which includes 442 insomniacs. In one out of five patients, insomnia is related to a known somatic factor, i.e. periodic movements in sleep or sleep apnea, which can only be reliably identified by PSG. A more differentiated analysis shows that PSG yields important diagnostic information in 50 to 75% of insomniacs. Three cases are reported, showing that even patients without clinical indications for sleep disturbance can have deficient sleep functions. If they can be specifically addressed, this may be the turning point of the treatment. Therefore, a wide application of PSG is favored.

Sleep alterations have been described in several neurodegenerative diseases yet are currently poorly characterized in amyotrophic lateral sclerosis (ALS). This study investigates sleep macroarchitecture and related hypothalamic signaling disruptions in ALS. Using polysomnography, we found that both patients with ALS as well as asymptomatic and mutation carriers exhibited increased wakefulness and reduced non-rapid eye movement sleep.

Background: Cold-water immersion (CWI) has gained popularity as a health and wellbeing intervention among the general population.
Objective: This systematic review and meta-analysis aimed to evaluate the psychological, cognitive, and physiological effects of CWI in healthy adults.
Methods: Electronic databases were searched for randomized trials involving healthy adults aged ≥ 18 years undergoing acute or long-term CWI exposure via cold shower, ice bath, or plunge with water temperature ≤15°C for at least 30 seconds.

Background: Chronic respiratory failure (CRF) is a critical complication in patients with chronic obstructive pulmonary disease (COPD) and is characterized by an increase in the arterial-alveolar oxygen gradient (A-aDO2). The long-term trajectory and prognostic significance remain unclear. This study aimed to assess the prognostic impact of A-aDO2 and elucidate its trajectory over ten years.

While most studies on Daylight Saving Time (DST) focus on human sleep and well-being, there is a dearth of understanding of how this sudden, human-mitigated change affects the routines of companion animals. The objective of this study was to assess how DST influenced the morning activity pattern of dogs (Canis familiaris). We used accelerometers to record activity in 25 sled dogs and 29 caregiver-companion dog dyads located in or near Ontario, Canada during the Fall Back time shift.

Study Objectives: Evaluate the performance of the SANSA device to simultaneously assess obstructive sleep apnea (OSA) and cardiac arrhythmias.
Methods: Participants suspected or known to have OSA underwent polysomnography (PSG) while wearing SANSA. SANSA's algorithm was trained using 86 records and tested on 67 to evaluate training bias.
