Continuous intraventricular cerebrospinal fluid pressure recording in hydrocephalic children during wakefulness and
Insights
Intracranial pressure (ICP) monitoring in children with hydrocephalus revealed significant increases during sleep, particularly during rapid eye movement phases. These sleep-related ICP elevations may impact hydrocephalus progression.
Area of Science:
- Pediatric Neurology
- Neurosurgery
- Sleep Medicine
Background:
- Hydrocephalus is a condition characterized by abnormal accumulation of cerebrospinal fluid.
- Normal intracranial pressure (ICP) in wakefulness does not exclude sleep-related abnormalities.
- Understanding ICP dynamics during sleep is crucial for managing pediatric hydrocephalus.
Purpose of the Study:
- To investigate intracranial pressure (ICP) and electroencephalographic (EEG) activity during sleep in children with hydrocephalus.
- To assess changes in ICP during different sleep stages, including slow-wave sleep and rapid eye movement (REM) sleep.
- To explore the potential implications of sleep-related ICP fluctuations on hydrocephalus progression.
Main Methods:
- Continuous 24-hour intracranial pressure (ICP) and electroencephalographic (EEG) recordings were performed.
- Five children diagnosed with hydrocephalus were included in the study.
- ICP and EEG data were analyzed during wakefulness, slow-wave sleep, and REM sleep.
Main Results:
- During slow-wave sleep, mean ICP and cardiac-related oscillations increased compared to wakefulness.
- Episodic ICP increases, up to sevenfold baseline values, were observed during sleep.
- In three patients, these episodic ICP surges correlated with rapid eye movement (REM) sleep phases.
Conclusions:
- Sleep, particularly REM sleep, is associated with significant intracranial pressure (ICP) elevations in children with hydrocephalus.
- These sleep-induced ICP fluctuations may play a role in the progression of hydrocephalus.
- Further research is warranted to elucidate the mechanisms and clinical significance of sleep-related ICP changes in pediatric hydrocephalus.
Abstract:
Continuous 24-hour recordings of intracranial pressure and electroencephalographic activity were made on five hydrocephalic children in whom, in the resting wakefulness state, the intracranial pressure (ICP) was considered normal. An increase in both the mean ICP and its oscillations related to cardiac systole was recorded during slow-wave sleep. Further episodic increases, up to a factor of 7 compared to wakefulness values, occurred during sleep. In three patients it was possible to correlate such episodic increases to the rapid eye movement phases of sleep. The authors discuss these phenomena and their possible implication in the progression of hydrocephalus.
