Disconnection and Unilateral Spatial Neglect

Neural Basis of Unilateral Spatial Neglect After Stroke: a Retrospective Disconnectome Based Study

Retrospective cohort study of consecutive patients investigated in a neurorehabilitation ward after a first hemispheric stroke. Unilateral spatial Neglect (USN) and other cognitive impairments (including attention, executive functions, memory) have been assessed in routine care at the subacute phase (<6 months). MRI scans have also been done in routine care.

The study aims at linking lesion characteristics, disconnections induced and expression of the different modalities of USN

Inclusion Criteria:

• First hemispheric adult stroke patient
• Non-opposed to inclusion
• Confirmed by MRI
• Assessment of cognitive functions during the subacute phase (3 weeks to 6 months after stroke onset

Exclusion Criteria:

• History of previous stroke or neurological disorders
• Inability to perform cognitive assessment due to severe comprehension, cognitive or psychiatric disorder
• Uncorrected severe loss of visual acuity
• Contra-indications to MRI
