Outcome Measures
Primary Outcomes (2)
Montreal Cognitive Assessment (MoCA)
It is a 30-point test about several cognitive domains (visuospatial/executive, naming, memory, attention, language, abstraction, delayed recall and orientation) and a screening tool used of MCI and dementia.
Changes from baseline after intervention week (two weeks), one and three months
NIH Toolbox
NIH Toolbox tests is a computarize test that acess fluid abilities (i.e., working memory, processing speed, episodic memory, and two aspects of executive functioning) and crystallized abilities (i.e., dependent upon past learning and experience), resulting in Standard Scores for these superordinate categories, as well as a total Composite score of all tests.These norms were previously reported to align with the age-corrected normative data for the traditional neuropsychological measures.
Changes from baseline after one and three months
Secondary Outcomes (4)
Neurovascular Coupling - Cerebral blood flow (fNIRS)
Changes on fNIRS signal from baseline after after intervention week (two weeks), one and three months
Brain Function (EEG)
Changes on EEG signal from baseline after after intervention week (two weeks), one and three months
Neurovascular Coupling - (DVA)
Changes on maximal arteriolar dilation and mean maximal venular dilation from baseline after intervention week (two weeks), one and three months
Blood markers
Changes on blood marker levels from baseline after intervention week (two weeks), one and three months
Study Arms (2)
sham tDCS
SHAM COMPARATORParticipants will receive sham (placebo) tDCS for 20 minutes, for 10 sessions
active tDCS
EXPERIMENTALParticipants will receive active tDCS for 20 minutes, for 10 sessions
Interventions
tDCS will deliver direct current through rubber electrodes in saline-soaked sponges. Device sends a low-level current from the positive electrode, the anode, to the negative electrode, the cathode. Direct current will be transferred by a saline-soaked pair of surface sponge electrodes (35cm2) and delivered by a specially developed, battery-driven, constant current stimulator with a maximum output of 10mA. The anode will be placed over the LDLPFC and the cathode over the contralateral supra-orbital area.
Eligibility Criteria
You may qualify if:
- \) ischemic stroke participants in sub-acute phase (at least 10 days after stroke event or discharge and under 5 months post-event) with cognitive dysfunction (MoCA \<26);
You may not qualify if:
- clinically significant or unstable medical or psychiatric condition;
- diagnosis of severe depression;
- history of relevant neurological diagnosis (e.g., epilepsy);
- previous neurosurgical procedure with craniectomy;
- contraindications to tDCS (implanted brain medical devices);
- severe visual impairment, hearing impairment, aphasia, neglect or dementia.
