![]() ![]() Possible alterations of brain WM were evaluated in terms of Fractional anisotropy (FA) by using Diffusion Tensor Imaging, whereas possible cognitive impairments were verified by means of neuropsychological testing, by studying: (1) General mental capability (2) Executive functioning (3) Visuospatial construction such as Rey Complex Figure (4) Attention and orientation: (5) Selective attention capacity and processing speed ability (6) Memory. For this purpose, 54 professional scuba divers (35 men and 19 women), with at least 2,000 dives in their careers, were studied. The purpose of this study is to verify whether the practice of the scuba diving is capable to determine a damage of the brain white matter (WM) in a dose dependent manner and, consequently, possible deficiency of their cognitive abilities. It seems probable that myelin can represent, in hyperbaric conditions, a preferential site for the accumulation of N2 in central nervous system (CNS). Nitrogen gas (N2), present in the normal atmospheric air, is a potential source of risk for scuba divers. 6Faculty of Human and Society Sciences, Kore University of Enna, Enna, Italy.Diagnostic Imaging, Interventional Radiology and Neuroradiology, Garibaldi Hospital, Catania, Italy 4Independent Researcher, Catania, Italy.3Department of Educational Sciences, University of Catania, Catania, Italy.2Study Center of Italian Osteopathy, Horus Social Cooperative, Catania-Ragusa, Italy.1Department of Biomedical and Biotechnological Sciences, University of Catania, Catania, Italy.Scavone 5, Vincenzo Perciavalle 6 and Donatella Di Corrado 6 Marinella Coco 1*, Andrea Buscemi 2, Valentina Perciavalle 3, Tiziana Maci 4, Gianluca Galvano 5, Antonio M. ![]()
