Auditory processing during childhood may be altered if there is any predisposing factor during the course of development. Neurological disorders are among the risk factors for auditory processing disorders. Some studies have shown verbal auditory processing disorder in children with epilepsy.
To verify the performance of children with epilepsy on a nonverbal dichotic test.
Thirty-eight subjects, 23 female and 15 male, ranging from 7 to 16 years of age with neurological diagnosis of idiopathic epilepsy, without clinical or imaging evidence of cerebral lesion were evaluated. Patients were divided into two groups: 23 patients diagnosed with partial seizures and 15 patients with generalized seizures. Illiterate children, children with hearing thresholds exceeding the normal range and with brain lesions confirmed either clinically or by imaging tests were excluded from the study group.
Analysis of the performance of epileptic patients with partial and generalized seizures on the Nonverbal Dichotic Test revealed that the majority of patients with epilepsy showed impairments in the test, with no significant differences related to seizure type, generalized or partial. Although patients with partial and generalized seizures performed similarly, all the epileptic patients showed different performance to a normal population.
This study revealed a high prevalence of impairments among epileptic patients in relation to nonverbal processing in a dichotic paradigm.
如果在发育过程中存在任何易感因素，儿童时期的听觉处理可能会发生改变。神经系统疾病是听觉处理障碍的危险因素之一。一些研究表明癫痫患儿存在言语听觉处理障碍。
验证癫痫患儿在非言语双耳分听测试中的表现。
对38名受试者进行评估，其中23名女性，15名男性，年龄在7至16岁之间，经神经学诊断为特发性癫痫，无脑部病变的临床或影像学证据。患者分为两组：23名诊断为部分性发作的患者和15名全身性发作的患者。文盲儿童、听力阈值超出正常范围以及经临床或影像学检查证实有脑部病变的儿童被排除在研究组之外。
对部分性发作和全身性发作的癫痫患者在非言语双耳分听测试中的表现分析显示，大多数癫痫患者在测试中表现出损伤，与发作类型（全身性或部分性）无关，无显著差异。尽管部分性发作和全身性发作的患者表现相似，但所有癫痫患者与正常人群相比表现不同。
本研究揭示了癫痫患者在双耳分听范式中与非言语处理相关的损伤发生率很高。
