“…However, although this prevalence was lower compared to that found in the divers, neither the number nor the size of lesions differed significantly between divers and controls. Todnem et al [5]and Rinck et al [25]reported significantly fewer lesions in commercial saturation divers (33 and 34%, respectively) than in their control subjects (43 and 42%, respectively). Since different imaging protocols were applied between groups, their comparability could be questioned.…”

“…The number of days in saturation and years performing saturation diving were correlated negatively to memory function. Todnem et al [5]found significantly more EEG abnormalities in their commercial divers than in controls. Of the divers, 33% had a history of severe neurological DCI, and occurrence of abnormal EEGs was highly correlated with exposure to deep saturation diving and a history of DCI.…”

“…In professional divers who perform deep saturation dives, abnormal electroencephalography and neurological findings have been reported [4, 5]. Moreover, it was found that sport divers and compressed-air workers are at risk of accumulating MR signal abnormalities indicating lesions in the central nervous system [6, 7].…”

“…Moreover, it was found that sport divers and compressed-air workers are at risk of accumulating MR signal abnormalities indicating lesions in the central nervous system [6, 7]. However, evidence on the association between neuroradiological changes and diving experience is contradictory [4, 5, 6, 7, 8]. The question whether compressed-air diving – that is performed worldwide by an increasing number of sport divers – causes functional brain damage in the absence of a history of DCI remains to be answered [9].…”

We investigated the association between MR signal abnormalities of the central nervous system, neuropsychologic performance and exposure indices in 20 experienced elderly compressed-air divers who had no history of neurological decompression illness (DCI). Results of MRI of the brain and psychometric testing were compared with 20 matched healthy commercial employees who never dived: 60% of the divers and 45% of the controls had hyperintense MR abnormalities. Among divers, both the number and the size of abnormalities correlated with hours diving in the deep air-diving range of 40–60 m (p < 0.05). Divers’ mental flexibility and visual tracking performance were decreased in comparison with controls (p < 0.05 and p < 0.01). Divers thus are at risk of detrimental long-term effects of compressed-air diving on the central nervous system even in the absence of a history of neurological DCI.

“…A Norwegian working group [2] examined 156 professional divers and 100 nondiving volunteers. The examination protocol included a history and clinical neurologic and electrophysiological tests (electroencephalogram [EEG]) as well as MRI of the brain.…”
