Shocking the brain back to reading: new hope for aphasia
NCT ID NCT06891638
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether adding a gentle brain stimulation technique called tDCS to a reading therapy (PMT) could help stroke survivors with aphasia read better. Six people with chronic aphasia took part. The goal was to see if the combination improved reading accuracy more than therapy alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial direct current stimulation (tDCS) and Phono-Motor Treatment (PMT)
- What this could lead to
- If it works, this could point toward a more effective reading therapy for people with aphasia after stroke.
- What could go wrong
- This was a very small, early study with only 6 participants, so results may not apply to everyone. The approach is still experimental.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Chronic (\>6 months) left-hemisphere stroke * Aphasia diagnosis. * Deficits in reading aloud. Exclusion Criteria: * Eye condition not correctable with lenses and interfering with reading (e.g., blindness) * Severe apraxia of speech or cognitive deficits preventing participation. * Participation in one-on-one aphasia rehabilitation during the study period. * Brain disorders other than stroke (such as Alzheimer's Disease or Dementia, Parkinson's Disease, etc) * Contraindications of tDCS or MRI * Skin condition affecting the scull (e.g., psoriasis) or open wounds at the stimulation site. * Presence of metallic implants (e.g., cardiac stimulators or pacemakers, cochlear implants) * History of ongoing/unmanaged seizers * Pregnancy * Claustrophobia * Inability to lie flat on the back
