NCT04883229

Brief Summary

The investigators will test the feasibility of using transcranial direct current stimulation (tDCS) and speech therapy to treat participants with motor speech disorders caused by Frontotemporal Lobar Degeneration Pathology including nonfluent variant Primary Progressive Aphasia, Progressive Supranuclear Palsy, Corticobasal Syndrome, or behavioral variant Frontotemporal Dementia. The investigators will deliver transcranial direct current stimulation (tDCS) either in a clinic setting at the University of California San Francisco, or in patients' homes, via a consumer tDCS device and videoconferencing. Transcranial direct current stimulation (tDCS) is a neuromodulation technique that can enhance the benefits of speech therapy treatment. Participants will receive a dose of tDCS stimulation + speech therapy and a dose of sham tDCS + speech therapy in a randomized double blind crossover study performed either in the clinic or at home via videoconferencing. This study can be performed entirely remotely.

Outcome Measures

Primary Outcomes (3)

  • Change in speech intelligibility

    Percent intelligible words, calculated by an SLP scoring each word spoken as intelligible or unintelligible, divided by total number of words spoken, during trained and untrained scripted speech.

    baseline and immediately after the first block of treatment

  • Change in speech intelligibility

    Percent intelligible words, calculated by an SLP scoring each word spoken as intelligible or unintelligible, divided by total number of words spoken, during trained and untrained scripted speech.

    baseline and immediately after the second block of treatment

  • Change in speech intelligibility

    Percent intelligible words, calculated by an SLP scoring each word spoken as intelligible or unintelligible, divided by total number of words spoken, during trained and untrained scripted speech.

    baseline and three months post treatment

Secondary Outcomes (1)

  • Feasibility of remote use of device

    Immediately after the second block of treatment

Study Arms (2)

tDCS +speech therapy followed by sham tDCS + speech therapy

EXPERIMENTAL
Device: Halo Neuroscience Neurostimulator

sham tDCS +speech therapy followed by tDCS + speech therapy

ACTIVE COMPARATOR
Device: Halo Neuroscience Neurostimulator

Interventions

Experimental: Neurostimulation of 2 milliamps anodal (active) tDCS stimulation for 20 mins during 1 hour speech therapy sessions, 3 times a week for 8 weeks, plus daily homework. Then a washout period of no treatment, followed by a 8 weeks of sham tDCS treatment during 1 hour speech therapy sessions, 3 times a week for 8 weeks, plus daily homework. Active comparator: Experimental: Sham tDCS stimulation for 20 mins during 1 hour speech therapy sessions, 3 times a week for 8 weeks, plus daily homework. Then a washout period of no treatment, followed by a 8 weeks of neurostimulation of 2 milliamps anodal (active) sham tDCS treatment during 1 hour speech therapy sessions, 3 times a week for 8 weeks.
