Title: [abstract] LONG TERM NEUROLOGICAL HEALTH EFFECTS OF DEEP DIVING.

Abstract: Thirty four deep divers, mean age 32.6 (24-42) years were examined 1 to 7 years after their last deep dive. Each had had 1 to 4 deep dives, mean depth 368 (190-500) msw. The breathing gas was heliox, in one dive heliox/trimix. In addition to the deep diving, their mean diving experience was 10 (0-20) years, with a mean of 482 (0-1610) days of air diving and 319 (0-700) days in saturation. The control group consisted of 74 men, mean age 32.8 (20-46) years, who never dived. The protocol included a clinical interview, a neurological examination and electroencephalography (EEG). Twenty divers had been treated for decompression sickness, 7 had been unconscious in connection with diving, 6 had had focal cerebral symptoms, and 5 had had spinal symptoms. Twelve divers had quit diving. Nine divers reported previous neurological symptoms, as compared to 3 in the control group (p<0.002). Four divers had episodes of cerebral functional disturbances (p<0.009); 2 of them had seizures, 1 had transitory cerebral ischemia and 1 had had an episode of transitory global amnesia. In addition, the divers reported more symptoms from the central nervous system (p<0.003), the autonomic nervous system (p<0.007), and the peripheral nervous system (p<0.007). They also had more abnormal findings from the sensory system (p<0.045) and coordination disturbances (p<0.038). There was no significant difference in the findings from cranial nerves (p=0.4) and the motor system (p=0.4). 17.6% (p=0.069) of the divers and 5.4% of the controls had an abnormal EEG, which is not statistically significant.
