ClinConnect Summary
This multi-site, phase 2a, randomized, sham-controlled, adaptive study aims to identify an optimal dose of a new treatment, cathodal direct current stimulation or C-tDCS, for acute ischemic stroke. This new treatment involves applying a weak inhibitory electrical current to the brain via scalp electrodes in acute stroke patients. The weak electrical current will electrically protect the brain cells not receiving enough oxygen and nutrients due to blood vessel blockage and increase the collateral blood flow to the brain.
The study primarily aims to find an optimal dose that shows adequate s...
