    Abstract

    <p> <h4 id="x-x-absSec_1"> Objective </h4> <p id="x-x-simple-para0020"> The goal of this study was to explore the relationship between language and memory lateralization in patients with <a> epilepsy </a> undergoing the intracarotid <a> amobarbital </a> procedure. <h4 id="x-x-absSec_2"> Methods </h4> <p id="x-x-simple-para0025"> In 386 patients, language lateralization and memory lateralization as determined by laterality index (LI) were correlated with each other. <h4 id="x-x-absSec_3"> Results </h4> <p id="x-x-simple-para0030"> Language lateralization and memory lateralization were positively correlated ( <em> r </em> = 0.34, <em> P </em> &lt; 0.01). Correlations differed depending on the presence and type of lesion ( <em> &chi; </em> <sup> 2 </sup> = 7.98, <em> P </em> &lt; 0.05). LIs correlated significantly higher ( <em> z </em> = 2.82, <em> P </em> &lt; 0.05) in patients with cortical <a> dysplasia </a> ( <em> n </em> = 41, <em> r </em> = 0.61, <em> P </em> &lt; 0.01) compared with the group without lesions ( <em> n </em> = 90, <em> r </em> = 0.16, <em> P </em> &gt; 0.05), with patients with <a> hippocampal </a> sclerosis falling between these two groups. Both memory ( <em> P </em> &lt; 0.01) and language ( <em> P </em> &lt; 0.01) LIs were higher in right- compared with left-sided lesions. <h4 id="x-x-absSec_4"> Conclusion </h4> <p id="x-x-simple-para0035"> Correlation of language and memory is more pronounced in patients with structural lesions as compared with patients without lesions on <a> MRI </a> . </p> </p> </p> </p></p>
