Two children with Friedreich's ataxia and six controls matched for age and Verbal IQ were administered a measure of short-term memory scanning and tests of attention, memory, language and abstraction. The patients demonstrated a deficit in information processing speed, decreased sustained attention and variable memory performance. The findings suggest that a deficit in information processing speed occurs early in the clinical course of Friedreich's ataxia and progresses as neurological status deteriorates.
对两名患有弗里德赖希共济失调症的儿童以及六名年龄和言语智商相匹配的对照组进行了短期记忆扫描测量以及注意力、记忆力、语言和抽象能力测试。患者表现出信息处理速度缺陷、持续注意力下降以及记忆表现不稳定。研究结果表明，信息处理速度缺陷在弗里德赖希共济失调症临床病程早期就已出现，并随着神经状态恶化而进展。
