Abstract:
The physiology of transient intracranial pressure (ICP) elevations (B waves), remains incompletely understood and appears to involve multiple mechanisms, including obstructive sleep apnea (OSA). Transient ICP elevations are associated with OSA and cyclic alternating pattern (CAP) metrics, suggesting a complex interplay between sleep fragmentation and ICP dynamics. Additionally, CAP metrics could complement standard OSA assessments, providing deeper insights into transient ICP fluctuations, particularly in conditions like normal-pressure hydrocephalus and idiopathic intracranial hypertension. Future studies should explore CAP-ICP interactions to elucidate their physiological and clinical implications.

NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Stages of Sleep
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...
