A dichotic listening test was administered to 22 elderly vascular patients with periventricular white matter changes on magnetic resonance imaging. We found four patients with a moderate-to-severe extent of these changes who showed a pattern of left-ear extinction. These findings suggest that periventricular lesions in patients with vascular risk factors may be associated with a functional disconnection of the interhemispheric auditory pathways.
对22名磁共振成像显示有脑室周围白质改变的老年血管性患者进行了双耳分听测试。我们发现4名这些改变程度为中度至重度的患者表现出左耳消音模式。这些发现表明，有血管危险因素的患者脑室周围病变可能与半球间听觉通路的功能断开有关。
