This study aims to evaluate whether a history of blast exposure at close proximity, defined as exposure within 30 feet, has long-term or lasting influences on cognitive outcomes among current and former military personnel.<\/jats:p><\/jats:sec><jats:sec id=\"S1355617722000558_as2\"><jats:title>Method:<\/jats:title><jats:p>One hundred participants were assigned to one of three groups based on a self-report history of blast exposure during combat deployments: 47 close blast, 14 non-close blast, and 39 comparison participants without blast exposure. Working memory, processing speed, verbal learning\/memory, and cognitive flexibility were evaluated using standard neuropsychological tests. In addition, assessment of combat exposure and current post-concussive, posttraumatic stress, and depressive symptoms, and headache was performed via self-report measures. Variables that differed between groups were controlled as covariates.<\/jats:p><\/jats:sec><jats:sec id=\"S1355617722000558_as3\"><jats:title>Results:<\/jats:title><jats:p>No group differences survived Bonferroni correction for family-wise error rate; the close blast group did not differ from non-close blast and comparison groups on measures of working memory, processing speed, verbal learning\/memory, or cognitive flexibility.

Limited characterization of blast contexts experienced, self-report of blast distance, and heterogeneity of injury severity within the groups are the main limitations of this study.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s1355617722000558","type":"journal-article","created":{"date-parts":[[2022,10,6]],"date-time":"2022-10-06T13:36:10Z","timestamp":1665063370000},"page":"551-560","source":"Crossref","is-referenced-by-count":8,"title":["Close proximity to blast: No long-term or lasting effect on cognitive performance in service members with and without TBI during blast exposure"],"prefix":"10.1017","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6403-7035","authenticated-orcid":false,"given":"L.
