dc.description.abstract BACKGROUND: Memory disturbance is a major concern in Norwegian saturation divers. Although many studies have been made to elucidate neuropsychological sequelae due to deep sea saturation diving, it remains unresolved whether or not deep sea saturation diving brings a permanent adverse effect on memory function. Moreover, the possibility of transient deterioration of memory function due to saturation diving has not been investigated until now. In the present study, memory function was measured before and after simulated deep-sea saturation dives in order to detect not only long-term but also short-term effects on memory function. MATERIALS AND METHODS: Subjects were 21 male professional divers (aged 30-40 years) who participated in saturation dives greater than 400 msw; they previously had various saturation diving experience (maximal depth: 60 to 440 msw; years of experience: two to 14 years). Memory function was measured by a computerized test named STM-COMET. This test analyzes three aspects of memory function, i.e., short-term memory, long-term memory and working memory; moreover, this test has six sets of different contents, thus enabling repetitive measurements without the learning effect. At first, the subjects were tested one week before the saturation dives. Then they were tested three times after the dives: four hours, one week and two weeks after the completion of decompression. RESULTS: The overall evaluation of memory function at the pre-dive measurement was slightly better than that of an age-matched control group, although the difference was not statistically significant. In addition, there was no correlation between the evaluation scores and saturation diving careers. The overall evaluation immediately after the decompression was almost the same as that of the pre-dive measurement, and it remained stable throughout the post-decompression measurements. CONCLUSIONS: This study indicates that deep-sea saturation diving itself causes neither long-term disturbance nor short-term change on memory function provided that both compression and decompression are properly performed. en
