Summary

Repetitive transcranial alternating current stimulation (rtACS) did not alter functional connectivity (FC) in chronic occipital stroke patients. Resting-state fMRI showed no significant changes in network parameters after rtACS compared to sham treatment.

Area of Science:

  • Neuroscience
  • Neuroimaging
  • Rehabilitation

Background:

  • Stroke can lead to reorganization of cortical networks, impacting functional connectivity (FC).
  • Resting-state functional magnetic resonance imaging (rsfMRI) is a key tool for assessing these network changes.
  • Understanding FC alterations is crucial for developing effective stroke rehabilitation strategies.

Purpose of the Study:

  • To investigate the effects of repetitive transcranial alternating current stimulation (rtACS) on functional connectivity (FC) in chronic occipital stroke patients.
  • To compare FC patterns between stroke survivors with visual field defects and healthy controls.
  • To evaluate the impact of rtACS on network parameters using rsfMRI.

Main Methods:

  • A randomized, sham-controlled study involving 16 chronic occipital stroke patients and 12 healthy controls.
  • rsfMRI scans were acquired at baseline, after two weeks of rtACS/sham, and after a two-month follow-up.
  • Multivariate regression and graph theory were employed to analyze FC and network properties.

Main Results:

  • No significant differences in whole-network FC or graph parameters were observed between stroke patients and controls at baseline.
  • Centrality eigenvector differed in perilesional regions, suggesting localized connectivity modifications.
  • rtACS treatment did not lead to systematic changes in prediction accuracy or network parameters compared to sham treatment.

Conclusions:

  • Whole-network FC in chronic occipital stroke patients is comparable to healthy individuals.
  • rtACS, in this context, did not demonstrate a significant effect on functional connectivity.
  • Localized connectivity differences in perilesional areas warrant further investigation.
