Reward exposure significantly reduced attentional impairments in stroke patients with left neglect. This finding offers new therapeutic avenues for brain damage-related attention disorders.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Clinical Neurology

Background:

  • Reward processing influences attention in healthy individuals.
  • Attentional impairments following focal brain damage remain understudied regarding reward modulation.
  • Left neglect is a common attentional deficit after right hemisphere stroke.

Purpose of the Study:

  • To investigate if reward can modulate attentional impairments in patients with left neglect due to right hemisphere stroke.
  • To explore the neural correlates of reward's effect on attention in this patient group.

Main Methods:

  • Two novel variants of a clinical cancellation task were employed.
  • Ten individuals with left neglect secondary to right hemisphere stroke participated.
  • Reward exposure was systematically applied during task performance.

Published on: June 6, 2025

Main Results:

  • Reward exposure significantly reduced neglect across the patient group.
  • Improvements were observed in total targets found, left-sided targets, and center of cancellation.
  • Lack of response to reward correlated with ipsilateral striatum damage.

Conclusions:

  • This study provides the first experimental evidence that reward can modulate attentional impairments after brain damage.
  • Findings suggest potential for developing behavioral and pharmacological therapies for attentional disorders.
  • Reward-based interventions may offer a novel approach for rehabilitation after stroke.
