Sleep and cardiac autonomic modulation in older adults: Insights from an at‐home study with auditory deep sleep stimulation

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it

Daily Predictors of Psychotic‐Like Experiences in Older Adults: The Role of Sleep Quality, Negative Emotions, and Cognitive Failures

Journal of Sleep Research, EarlyView.

However, their night‐to‐day associations remain understudied in older adults. 72 participants aged 50–79 took part in a home‐based sleep study.

Sleep Preserves, Wake Differentiates: Strength‐Dependent Forgetting of Declarative Memories Across the Retention Interval

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep benefits memory, but the extend to which this benefit depends on initial memory strength remains heavily debated. We examined whether sleep preferentially stabilises weakly versus strongly encoded declarative memories, and whether classical sleep oscillations contribute to this effect.
