Abstract: 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.
