[Analysis of the possible mechanism for decrease of intracranial pressure following arousal stimulation].

M Motomiya

    [Hokkaido Igaku Zasshi] the Hokkaido Journal of Medical Science
    |May 1, 1984
    PubMed
    Summary

    Arousal from sleep causes a rapid drop in intracranial pressure (ICP). This neurogenic cerebral vasoconstriction, not changes in blood gases, is the primary mechanism.

    Area of Science:

    • Neuroscience
    • Physiology

    Context:

    • The decrease in intracranial pressure (ICP) and cerebral blood flow upon waking is a known phenomenon.
    • However, the precise physiological mechanisms driving this change remain unclear.

    Purpose:

    • To elucidate the mechanism behind the rapid decrease in ICP following arousal from sleep.
    • This study compares clinical data from arousal to data from hyperventilation to identify the response organ and triggering mechanism.

    Summary:

    • ICP monitoring and physiological parameters (blood pressure, pulse, respiration, arterial PCO2, pH) were analyzed in subjects upon arousal.
    • No significant difference in the time constant of ICP decline was observed between arousal and hyperventilation, suggesting the cerebrovascular wall as the common response organ.
    • A significant difference in the time lag to ICP decrease initiation indicates distinct triggering mechanisms, with neurogenic cerebral vasoconstriction identified as the cause for arousal-induced ICP drop.

    • Provides a clearer understanding of cerebrovascular regulation during state changes.
    • Offers insights into the physiological responses influencing intracranial pressure.
