Abstract：
INTRODUCTION:Grammar is a core component of the language system, yet it is rarely assessed during the Wada (intracarotid amobarbital) test. It is hypothesized that adding grammar tests to the recovery phase of the Wada test will increase our ability to lateralize language function. METHOD:Sixteen individuals (nine females, fifteen right-handed, mean age 38.4 years, SD=10.7) with medically refractory temporal lobe epilepsy participated in the study. On EEG ten patients had seizures originating in the left hemisphere (LH), five in the right hemisphere (RH), and one was insufficiently lateralized. We included only patients who were LH-dominant on the standard test in the encoding phase of the Wada test. In the recovery phase of Wada testing the participants underwent evaluation with a standard language and a new test of grammar, the CYCLE-N. Ten patients underwent bilateral injections, six unilateral (one RH, five LH). RESULTS:As expected, injection in the LH decreased language performance to a greater extent than injection to the RH on both tests. However, the CYCLE-N produced more profound language deficits in the injected LH compared to the RH (p=0.01), whereas the standard tests did not cause such pronounced differences (p=0.2). CONCLUSION:The results suggest that the standard tests did not significantly differentiate the effects of the injections and the CYCLE-N, for the most part, did. Our results are of particular relevance to patients who are too obtunded to speak in the encoding phase. In sum, the CYCLE-N may be helpful in assessing hemispheric dominance for language.
