This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing a treatment called transcranial alternating current stimulation (tACS) to help people recover language and speech abilities after a stroke. tACS uses electrical currents delivered through electrodes on the scalp to gently stimulate brain areas involved in language. The goal is to help reconnect communication pathways in the brain that were damaged by the stroke.
Stroke can severely damage the brain's language centers, leaving people unable to speak, understand, read, or write clearly. Current treatments like speech therapy help, but benefits are often limited. This trial exists because researchers believe that adding brain stimulation to therapy might improve recovery by helping damaged brain areas communicate better.

You will receive tACS sessions where small electrodes are placed on your scalp to deliver painless electrical stimulation. During each 20-minute session, the stimulation is gradually turned on and then delivered at different frequencies. You will participate in a sham-controlled design, meaning some sessions will include real stimulation and others will be sham (no active stimulation), though you won't know which. The study involves multiple visits where you'll also complete language and memory testing.
