Primary Progressive Aphasia (PPA) is a syndrome due to different neurodegenerative disorders selectively disrupting language functions. PPA specialist care is underdeveloped. There are very few specialists (neurologists, psychiatrists, neuropsychologists and speech therapists) and few hospitals- or community-based services dedicated to diagnosis and continuing care. Currently, healthcare systems struggle to provide adequate coverage of diagnostic services, and care is too often fragmented, uncoordinated, and unresponsive to the needs of people with PPA and their families. Recently attention has been gained by digital-health technologies, such immunoassay analyzer and high-field MRI, the most promising approaches to increase our understanding of neurodegeneration, and by new non-invasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) that allow a personalized treatment approach. Our goal is to develop a new treatment approach in PPA in which the regional secondary care centers participating in this project should be the hub of a regional network. The MAINSTREAM (WP2- Efficacy of personalized training in the early stage of PPA) looks forward to introduce and evaluate therapeutic innovation such as tDCS coupled with language therapy in rehabilitation settings (WP2 Early Treatment).
This objective will be pursued by conducting a randomized controlled pilot study in order to evaluate the efficacy of a combined treatment of Active (anodal) tDCS and individualized language training compared to Placebo tDCS combined with individualized language training in a subgroup of mild PPA defined using the Progressive Aphasia Severity Scale (PASS) (Sapolsky D, Domoto-Reilly K, Dickerson BCJA. Use of the Progressive Aphasia Severity Scale (PASS) in Monitoring Speech and Language Status in PPA. (2014) 28(8-9):993-1003).
60 patients with PPA will be recruited from IRCCS Istituto Centro San Giovanni di Dio, Fatebenefratelli, Brescia; IRCCS Fondazione Istituto Neurologico Nazionale C. Mondino, Pavia; Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan and Fondazione Don Carlo Gnocchi - ONLUS, Milan.
The diagnostic evaluation will include cognitive and language testing, neurologic examination and neuroimaging (Magnetic Resonance Imaging (MRI) or Positron Emission Tomography PET)).
All the patients will undergo five consecutive days a week for two weeks of treatment sessions of 25 minutes:
The two groups will be matched for sex, age, education, language severity (as defined in the Frontotemporal Dementia Clinical Dementia Rating subscale), and overall severity according to the FTD Clinical Dementia Rating.
Two trained neuropsychologists will administer the neuropsychological testing at baseline (T0), post-treatment (T1) and 3-months (T2) follow-up. All of assessments will be conducted by the same assessor.
To elucidate the mechanisms underlying tDCS effects, Magnetic Resonance Imaging (MRI) and bimolecular data will be collected at T0 and T1 (after the treatment).
