Right neglect after left brain damage occurs in a substantial proportion of patients. This finding highlights the importance of considering neglect in rehabilitation planning for left hemisphere stroke survivors.

Area of Science:

  • Neuroscience
  • Neurology
  • Clinical Psychology

Background:

  • Right neglect, a deficit in attention to the left side of space, is less studied after left brain damage compared to right brain damage.
  • Previous research primarily focused on left neglect following right hemisphere strokes.

Purpose of the Study:

  • To assess the prevalence and characteristics of contralateral (right) neglect in subacute left hemisphere stroke patients.
  • To utilize a comprehensive, validated test battery for accurate neglect assessment.

Main Methods:

  • Evaluated 78 patients with subacute left hemisphere strokes.
  • Employed a nonverbal test battery including assessments for anosognosia, visual extinction, gaze orientation, personal neglect, and spatial neglect in peripersonal space.

Main Results:

  • While less frequent than in right hemisphere damage, right neglect was detected in 10-13% of patients on specific tasks.
  • A combined battery approach identified some degree of neglect in 43.5% of patients.
  • Damage to the posterior association cortex correlated with more frequent and severe neglect.

Conclusions:

  • Right neglect occurs in a significant minority of left hemisphere stroke patients, even in the subacute phase.
  • The findings underscore the need to include neglect assessment and rehabilitation in the care of patients with left brain damage.
  • A comprehensive test battery is more sensitive in detecting neglect than individual tests.
