Clinical Dementia Rating score\n\nThe clinical dementia rating (CDR) is a clinical global rating scale administered to both the participant and the caregiver, assessing 6 domains of participant function: memory, orientation, judgement and problem solving, community affairs, home and hobbies and personal care. Each domain is based on a 5-point scale ranging from no impairment=0, questionable impairment=0.5, mild impairment=1, moderate impairment=2 to severe impairment=3. The global CDR score is computed via a memory-weighted averaging algorithm of the six domain scores and ranges from 0 to 5.

Brain network stimulation will be carried out with transcranial direct current stimulation (tDCS). Target networks will be the default mode network (DMN) and salience network (SN). Twenty AD and 20 bvFTD patients will be recruited and assessed with a comprehensive clinical, behavioral and cognitive battery, and 3 Tesla MRI scan (including resting-state functional MRI, arterial spin labeling, diffusion tensor imaging, structural MRI) at three time-points: baseline, after tDCS, and after 6 months. Patients will be randomized to 2 arms: anodal stimulation of the disease-specific network (DMN in AD, SN in bvFTD) or cathodal stimulation of the anti-correlated network (SN in AD, DMN in bvFTD). The intervention will consist of 10 tDCS sessions over two weeks. Cerebrospinal fluid (CSF) samples will be collected at baseline for biomarker's assessment; blood samples will be collected at each time-point to assess changes in peripheral inflammatory markers. Blood and CSF collection will be optional. A sample of 20 elderly controls will be included for baseline comparisons."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '50 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Diagnosis of AD or bvFTD according to current clinical criteria (Albert et al., 2011; Rascovsky et al., 2011)\n* Ability to provide written informed consent\n* Availability of a collateral source\n\nExclusion Criteria:\n\n* Moderate/severe dementia\n* Presence of any medical or psychiatric illness that could interfere in completing assessments\n\nExclusion Criteria for MRI and tDCS:\n\n* metal implants, pace-makers, prosthetic heart valves\n* claustrophobia\n* history of epilepsy\n* pregnancy\n\nExclusion Criteria for controls:\n\n* Current or past history of clinical, neurological, or psychiatric conditions that could interfere with the assessment (e.g., transient ischemic attack, ictus, head trauma, epilepsy, multiple sclerosis, neuropathy, mood disorders, substance abuse)'}, 'identificationModule': {'nctId': 'NCT03422250', 'acronym': 'NetCogBs', 'briefTitle': "Non-invasive Stimulation of Brain Networks and Cognition in Alzheimer's Disease and Frontotemporal Dementia", 'organization': {'class': 'OTHER', 'fullName': 'IRCCS Centro San Giovanni di Dio Fatebenefratelli'}, 'officialTitle': "A Non-invasive, Multimodal Approach to Restore Functional Networks and Cognition in Alzheimer's Disease and Frontotemporal Dementia", 'orgStudyIdInfo': {'id': 'GR-2011-02349787'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Arm 1', 'description': "Alzheimer's disease (AD): anodal tDCS of the default mode network (DMN)", 'interventionNames': ['Device: transcranial direct current stimulation (tDCS)']}, {'type': 'EXPERIMENTAL', 'label': 'Arm 2', 'description': "Alzheimer's disease (AD): cathodal tDCS of the salience network (SN)", 'interventionNames': ['Device: transcranial direct current stimulation (tDCS)']}, {'type': 'EXPERIMENTAL', 'label': 'Arm 3', 'description': 'Behavioral-variant frontotemporal dementia (bvFTD): anodal tDCS of the salience network (SN)', 'interventionNames': ['Device: transcranial direct current stimulation (tDCS)']}, {'type': 'EXPERIMENTAL', 'label': 'Arm 4', 'description': 'Behavioral-variant frontotemporal dementia (bvFTD): cathodal tDCS of the default mode network (DMN)', 'interventionNames': ['Device: transcranial direct current stimulation (tDCS)']}], 'interventions': [{'name': 'transcranial direct current stimulation (tDCS)', 'type': 'DEVICE', 'description': '10 daily 25-minutes tDCS sessions over two weeks.', 'armGroupLabels': ['Arm 1', 'Arm 2', 'Arm 3', 'Arm 4']}]}, 'contactsLocationsModule': {'locations': [{'zip': '25125', 'city': 'Brescia', 'country': 'Italy', 'facility': 'IRCCS Centro San Giovanni di Dio Fatebenefratelli', 'geoPoint': {'lat': 45.53558, 'lon': 10.21472}}], 'overallOfficials': [{'name': 'Michela Pievani, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'IRCCS Istituto Centro San Giovanni di Dio Fatebenefratelli, Brescia, Italy'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'IRCCS Centro San Giovanni di Dio Fatebenefratelli', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Principal Investigator', 'investigatorFullName': 'Michela Pievani', 'investigatorAffiliation': 'IRCCS Centro San Giovanni di Dio Fatebenefratelli'}}}}
