Oct 7, 2021 · We found that studies of tDCS in PPA have clinical and methodological and heterogeneity regarding patient populations, stimulation protocols and study design.

May 21, 2018 · Transcranial direct current stimulation (tDCS) is an innovative technique recently shown to improve language outcomes even in neurodegenerative conditions such as primary progressive aphasia (PPA), but the underlying brain mechanisms are not known.

We investigated whether two weeks of daily transcranial direct current stimulation (tDCS) treatment would improve language abilities in six people with a non-fluent form of PPA. tDCS was applied in an unblinded trial at an intensity of 1.5 mA for 20 min/day over 10 days.

Oct 7, 2021 · Studies of tDCS in PPA have clinical and methodological and heterogeneity regarding patient populations (PPA variant, language background, severity, etc.), and stimulation protocols (electrode configuration, combined language therapy), and study design.

Apr 7, 2025 · We investigated how high-definition transcranial direct current stimulation (HD-tDCS) targeting separate brain regions could change cognitive performance and brain responses in primary progressive aphasia (PPA) as a novel approach of intervention. Cognitive functions are often impaired in PPA.

Apr 7, 2025 · Primary progressive aphasia (PPA) is a group of dementias characterized by progressive loss of specific language functions with relative sparing of other cognitive domains. Transcranial direct current stimulation (tDCS) has been …

Jan 1, 2018 · tDCS is a potentially useful adjunct to language therapy in PPA. Transcranial direct current stimulation (tDCS) has been recently shown to improve language outcomes in primary progressive aphasia (PPA) but most studies are small and the …

Transcranial direct current stimulation (tDCS) has been shown to be a valuable adjunct to speech and language therapy, mainly in stroke rehabilitation and recently in primary progressive aphasia.

Sep 5, 2018 · Introduction: Transcranial direct current stimulation (tDCS) has been recently shown to improve language outcomes in primary progressive aphasia (PPA) but most studies are small and the influence of PPA variant is unknown.

Jun 18, 2021 · A variety of tDCS approaches has been used to investigate the potential of tDCS to improve language outcomes, or slow down the decay of language competences caused by Primary Progressive Aphasia (PPA).
