Details and patient eligibility

About

The primary aim of this study is to investigate whether multisensory integration (MSI) mechanisms observed in patients with right hemisphere lesions without neglect remain intact compared to patients with Unilateral Spatial Neglect (USN).

This study also allows for a direct comparison between results from paper-based tests and computerized tests, as well as between patients with right hemisphere lesions without neglect and USN patients. The secondary objectives are:

To compare these results in order to obtain a more refined definition of USN at both the unisensory level (as computerized tests are rarely used in hospital settings but have proven effective in diagnosing USN) and the multisensory level (since USN is not generally tested in the auditory modality).

To measure eye movements in all patients in the study, as this can provide useful information for characterizing patient deficits.

Inclusion criteria

  • Patients will be included in the study if they have:
  • Right hemisphere stroke
  • Presence of USN assessed through the Apple Cancellation
  • Age between 18 and 85 years
  • Signed informed consent
  • Both male and female participants

As a control group, patients will also be included if they have:

  • Right hemisphere stroke
  • Absence of USN assessed through the Apple Cancellation
  • Age between 18 and 85 years
  • Signed informed consent
  • Both male and female participants.

Exclusion criteria

  • Both patients with USN and control patients will be excluded if they:
  • Are minors
  • Are unable to give their consent to participate in the study
  • Have significant language deficits (production and comprehension) (e.g., unable to give a verbal response or understand instructions)
  • Have hemianopia
  • Have severe hearing impairments that cannot be corrected (e.g., with hearing aids)
  • Have severe uncorrected visual impairments (e.g., glaucoma)
  • Have a history of psychiatric disorders or substance abuse.
