Summary

This trial will test the feasibility and effectiveness of tDCS in people with primary progressive aphasia.

Who is the study for?
This trial is for individuals aged 50-80 with non-fluent or logopenic primary progressive aphasia (PPA), who have at least a high school education and can consent to the study. Excluded are those with recent participation in other trials, left-handedness, pregnancy, severe cardiopulmonary disorders, pacemakers, terminal illness, major psychiatric issues that affect study compliance, previous skull breaches, certain MRI exclusions like claustrophobia or metal implants near the eye.
What is being tested?
The trial tests transcranial direct current stimulation (tDCS) combined with language therapy against a sham tDCS plus language therapy to see if it helps PPA patients. It's a Phase II multi-center clinical trial conducted by Johns Hopkins University, University of Pennsylvania and University of Toronto.
What are the potential side effects?
tDCS is generally considered safe but may cause mild side effects such as tingling on the scalp where electrodes are placed, fatigue after treatment sessions or slight itching under electrode pads during stimulation.
