    Deep sea diving can cause neurological issues like tremor and memory loss, known as High Pressure Nervous Syndrome (HPNS). Some divers experience lasting brain dysfunction after multiple dives.

    Area of Science:

    • Physiology
    • Neurology
    • Diving Medicine

    Background:

    • Deep sea diving presents significant physiological challenges.
    • High Pressure Nervous Syndrome (HPNS) is a known risk for divers.

    Purpose of the Study:

    • To investigate neurological symptoms in professional divers at extreme depths.
    • To assess potential long-term effects of deep diving on cognitive function.

    Main Methods:

    • Investigated 23 professional divers before and after dives to 300-350m.
    • Monitored 12 divers during actual dives.
    • Conducted post-dive neuropsychological and neurophysiological assessments.

    Main Results:

    • All divers experienced neurological symptoms during compression, including tremor, ataxia, and memory reduction.

  • No significant changes were observed after a single dive.
  • A group of 6 divers showed clear impairment after two dives separated by 3 months.
  • Transient focal cerebral dysfunction was noted in 4 divers post-dive.

    • Conclusions:

    • Deep diving can induce transient brain dysfunction, particularly affecting short-term memory.
    • Repeated exposure to extreme pressure may lead to persistent neurological impairment.
    • HPNS symptoms vary individually and may unmask pre-existing neurological conditions.
