Summary
Extensive compressed air diving did not show an increased prevalence of brain white matter changes in elderly divers compared to non-divers. Magnetic resonance imaging (MRI) revealed no significant differences in white matter abnormalities between the groups.
Area of Science:
- Neurology
- Radiology
- Diving Medicine
Background:
- Cerebral white matter changes are common in aging.
- The long-term effects of compressed air diving on the brain are not fully understood.
Purpose of the Study:
- To assess the prevalence of white matter changes in elderly compressed air divers with extensive diving histories.
- To compare these findings with age-matched control subjects who have never dived.
Main Methods:
- Magnetic resonance (MR) imaging, including fluid-attenuated inversion recovery and T1/T2-weighted sequences, was used.
- The study included 59 experienced elderly divers and 48 control subjects.
- Subjects were matched for age, BMI, and lifestyle factors like alcohol and smoking history.
Main Results:
- No morphological abnormalities were observed in the brains of divers via MR imaging.
- There were no significant differences in the prevalence of white matter changes between the compressed air divers and the control group.
- The findings suggest that extensive compressed air diving may not lead to detectable radiological changes on MR imaging.
Conclusions:
- Compressed air diving does not appear to increase the prevalence of cerebral white matter changes in healthy elderly individuals.
- Radiological evidence of white matter changes is not a necessary consequence of extensive compressed air diving.
- Further research could explore potential subtle or long-term effects not detected in this study.
