Summary
Cathodal transcranial direct current stimulation (tDCS) significantly improved picture naming accuracy in chronic post-stroke aphasia patients. Anodal and sham tDCS showed no significant effects, highlighting cathodal tDCS as a potential therapy for stroke recovery.
Area of Science:
- Neuroscience
- Neurology
- Rehabilitation Medicine
Background:
- Stroke often results in aphasia, impacting communication.
- Functional recovery after stroke is a significant clinical challenge.
- Transcranial direct current stimulation (tDCS) is explored as an adjuvant therapy.
Purpose of the Study:
- To evaluate the efficacy of cathodal and anodal tDCS on picture naming in chronic post-stroke aphasia.
- To assess the impact of tDCS on accuracy and response time in a picture naming task.
Main Methods:
- Eight chronic non-fluent aphasic patients participated.
- Picture naming accuracy and response time were assessed.
- Stimulation protocols included anodal tDCS, cathodal tDCS, and sham tDCS (2 mA, 10 minutes).
Main Results:
- Cathodal tDCS significantly improved picture naming accuracy by 33.6%.
- Anodal tDCS and sham stimulation did not yield significant improvements.
- No significant changes in response time were reported for any condition.
Conclusions:
- Cathodal tDCS shows promise as a non-invasive neuromodulation technique for improving language function in post-stroke aphasia.
- Targeted cathodal stimulation over left frontotemporal areas may facilitate recovery of naming abilities.
- Further research is warranted to optimize tDCS parameters and confirm long-term effects.
