A Systematic Review of Transcranial Direct Current Stimulation in Primary Progressive Aphasia: Methodological Considerations

It is found that studies of tDCS in PPA have clinical and methodological and heterogeneity regarding patient populations, stimulation protocols and study design, and the role neuroimaging can play in study protocols and interpreting results is highlighted.

Individualized Treatment With Transcranial Direct Current Stimulation In Patients With Chronic Nonfluent Aphasia Due To Stroke (S21.007)

Optimal electrode arrangement appears to vary across participants, suggesting that individualized treatment of post-stroke non-fluent aphasia by transcranial direct current stimulation may further improve language outcomes.

Anatomical Parameters of tDCS to Modulate the Motor System after Stroke: A Review

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation method to modulate the local field potential in neural tissue and consequently, cortical excitability. As tDCS is

Electrical stimulation of the motor cortex enhances treatment outcome in post-stroke aphasia.

The results provide the first evidence from a randomized, controlled trial that transcranial direct current stimulation can improve both function and activity-related outcomes in chronic aphasia, with medium to large effect sizes, and that these effects are maintained over extended periods of time.

Transcranial direct current stimulation in post-stroke sub-acute aphasia: study protocol for a randomized controlled trial

The results will contribute to the discussion on whether tDCS should be implemented in regular aphasia rehabilitation programs for the sub-acute post-stroke population in terms of (cost-)effectiveness.

Transcranial direct current stimulation effects on neural processing in post‐stroke aphasia

Compared with healthy controls, anodal‐tDCS resulted in overall “normalization” of brain function in the patients, demonstrating for the first time how tDCS modulates neural processing in stroke patients.

Use of tDCS in Aphasia Rehabilitation: A Systematic Review of the Behavioral Interventions Implemented With Noninvasive Brain Stimulation for Language Recovery.

No one behavioral approach stands out as the best treatment to combine with tDCS for the promotion of language recovery, but several methodological considerations for future investigations are highlighted.

Transcranial Direct Current Stimulation (tDCS) and Language/Speech: Can Patients Benefit from a Combined Therapeutic Approach?

The modulation of cognitive functions by noninvasive stimulation of the human brain has gained increasing attention over the last few decades. Transcranial direct current stimulation (tDCS) is an

Transcranial Direct Current Stimulation as a Novel Method for Enhancing Aphasia Treatment Effects

Results on the effectiveness of tDCS at boosting recovery outcomes are preliminary but promising with a number of themes emerging.



Transcranial Direct Current Stimulation in Stroke Rehabilitation: A Review of Recent Advancements

It is proposed that cortical synchrony may represent a biomarker of tDCS efficacy to indicate communication between affected areas and how stimulation parameters could be optimized based on electrophysiological activity.

The Factors Associated with Good Responses to Speech Therapy Combined with Transcranial Direct Current Stimulation in Post-stroke Aphasic Patients

Speech therapy with tDCS was established as a treatment tool for aphasic patients after stroke and lower initial severity was associated with good responses.

Improved naming after transcranial direct current stimulation in aphasia

Whereas anodal and sham tDCS failed to induce any changes, cathodal tDCS significantly improved the accuracy of the picture naming task by a mean of 33.6% (SEM 13.8%).

Non-Invasive Brain Stimulation Enhances the Effects of Melodic Intonation Therapy

The hypothesis that, as the brain seeks to reorganize and compensate for damage to left hemisphere language centers, combining anodal-tDCS with MIT may further recovery from post-stroke aphasia by enhancing activity in a right hemisphere sensorimotor network for articulation is supported.

Shaping the optimal repetition interval for cathodal transcranial direct current stimulation (tDCS).

The effects of different break durations on cathodal tDCS-induced cortical excitability alterations are explored and it is suggested that, for prolonging the aftereffects of cathodAL tDCS, stimulation interval might be important.
