We tested the efficiency of three attentional systems (spatial orienting, phasic alerting and executive control) in patients with Parkinson’s disease (PD), by using a modified version of the Attention Network Test, which employs acoustic tones to modulate phasic alertness. PD patients were generally slower than age-matched controls, but they showed a similar pattern of effects and interactions. Responses were faster with congruent than with incongruent stimuli (executive control), with valid visual cues than with invalid or no cues (orienting), and when acoustic tones preceded the target (alerting). This last effect was significantly larger in PD patients than in controls. We concluded that, for the present group of patients, the activity of attentional networks was relatively normal, if slowed. Slowed responses in PD may be improved by the use of acoustic stimuli, with potential clinical implications.

帕金森病中的注意网络。

我们通过使用注意力网络测试的修改版本测试了帕金森病 (PD) 患者的三个注意力系统（空间定向、相位警报和执行控制）的效率，该测试采用声调来调节相位警报。PD 患者通常比年龄匹配的对照组慢，但他们表现出相似的效应和相互作用模式。一致的反应比不一致的刺激（执行控制）更快，有效的视觉线索比无效或没有线索（定向），以及当声调在目标之前（警告）时更快。PD 患者的最后一种效应明显大于对照组。我们得出的结论是，对于本组患者，注意力网络的活动如果减慢则相对正常。
