Prism adaptation can improve unilateral neglect symptoms, even for mental imagery. This study shows prism exposure helped patients recall left-sided information from internal maps, suggesting benefits beyond sensory-motor changes.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Rehabilitation Medicine

Background:

  • Unilateral neglect is a cognitive disorder impacting spatial awareness.
  • Prism adaptation has previously shown promise in ameliorating some neglect symptoms.

Purpose of the Study:

  • To investigate the effect of prism adaptation on imagery neglect.
  • To determine if prism adaptation can improve the mental evocation of neglected information.

Main Methods:

  • Two patients with unilateral neglect underwent prism adaptation therapy.
  • Performance on conventional neglect tests and mental imagery tasks was assessed before and after adaptation.

Main Results:

  • Prism adaptation led to a significant recovery of imagery neglect in both patients.

  • Patients could mentally evoke left-sided information from an internal map of France post-adaptation.
  • Improvements were observed beyond visuomotor response alterations.

    • Conclusions:

    • Prism adaptation may positively influence higher cognitive functions, including mental space representation.
    • This suggests a potential therapeutic benefit of prism adaptation for cognitive aspects of neglect.
