新华社悉尼9月8日电在纸上画螺旋线就可诊断疾病？澳大利亚皇家墨尔本理工大学的研究人员开发出一款软件，通过分析绘图能力诊断帕金森病，诊断准确率可达93%。
帕金森病是一种常见的中枢神经系统变性疾病，主要症状包括肢体震颤、行动迟缓等，目前还没有根治方法，早期诊断也有不少困难。
先前研究发现，严重的帕金森病患者在素描绘画时，笔速和笔力会减缓、减弱。皇家墨尔本理工大学研究人员据此开发出一款诊断软件，可实时记录并分析使用者画螺旋线时的笔速和笔力，判断其是否患有帕金森病以及病情的严重程度。
研究人员迪内希·库马尔介绍，这款软件可在患者还未出现明显身体症状时诊断出疾病，有助于及早治疗。“开始治疗帕金森病的时间至关重要，因为病人一旦出现颤抖或肢体僵硬等症状，就已经太迟了。”
据介绍，这款软件使用简便，只需纸、笔和一块数字手写板。研究人员希望这项技术将来可用于帕金森病筛查测试，以便尽早发现病情，及时介入治疗。
这项成果发表在瑞士学术刊物《神经学前沿》新一期上。
