dc.description.abstract BACKGROUND: Changes in cognitive functioning and behavior have been well documented in the diving community during compressed air diving when the verified changes occur during (i.e. cerebral decompression sickness). This meta-analysis synthesized the neuropsychological literature pertaining to diving and estimated the differences found in the research between different diving populations. METHODS: Fourteen studies were identified for inclusion, and four of these studies having multiple comparisons for inclusion (18 total effect sizes). Neuropsychological measures were organized into broad domains of functioning: Attention, Intelligence, Language, Memory, Executive Functioning and Motor/Sensory. Studies were divided into five categories: divers vs. control, impaired vs. non-impaired, diver vs. diver control, pre-post dive, and impaired.RESULTS: Divers that have a history of decompression sickness perform significantly worse on neuropsychological evaluations than divers without a history of cerebral decompression sickness (Z = 22.35, p greater than .01). Neuropsychological impairment for this sample seemed to occur in all domains suggesting significant global cognitive deficits. The impaired dive category demonstrated significant effect size changes (Z = 2.22, p = .03) that associates significant improvement in neuropsychological functioning for individuals following treatments. However, the divers vs non-diver comparison demonstrated a positive effect size suggesting that overall, the neuropsychological functioning of divers was greater than those of the selected control groups (Z = -2.95, p greater than .01). Though overall effect size was significant following treatment, the primary domains that demonstrated a significant effect sizes denoting change within that domain were attention and motor functioning. CONCLUSIONS: This synthesis of the literature supports the common belief that significant cerebral incidents during diving may impact the long-term cognitive capacity of divers, even when the control group is a closely matched population of non-injured divers. Nevertheless, the paucity of neuropsychological evidence in the literature was revealed and the exact nature of deficits have not been fully explored. en_US
