Repetitive Transcranial Magnetic Stimulation (rTMS) has gained evidence as an effective tool to modulate brain networks connectivity, leading to a recovery or reorganization of both local and remote brain regions functionally connected to the stimulated area. The investogators propose an innovative tailored network-based rTMS treatment to ameliorate cognitive symptoms in mild AD, through the boosting of connectivity within brain networks affected by AD pathophysiology. The combination of the proposed intervention with an integrated multi-modal imaging approach will allow to evaluate the neural mechanisms underlying the clinical response to the treatment and to define quantitative markers of clinical impact on AD. If successful, the present proposal would immediately impact on patient's quality of life, with important implications for the time and costs of delivery of rehabilitative services.", 'detailedDescription': "Currently, no effective cure is available for Alzheimer's disease (AD). Repetitive Transcranial Magnetic Stimulation (rTMS) has gained increasing attention as a potential treatment for various neurological and psychiatric disorders, but available rTMS studies are flawed by inaccurate anatomical targeting, inadequate sample size, unsatisfactory controls and lacking blindness. To date, the elective target area of rTMS interventions in AD has been the dorsolateral prefrontal cortex (DLPFC), a core area of the Central Executive network (CEN), which plays a key role in regulating executive functions, attention and working memory. While the CEN has recently been described as dysfunctional in AD, AD pathophysiology has been mainly associated with the breakdown of the Default Mode network (DMN) and with structural disconnection of its parietal nodes. The DMN plays a crucial role in episodic memory retrieval and incorporates various brain regions, among which parietal areas are highly connected with the rest of the brain. The present multicenter, double-blind, randomized and placebo-controlled study has the ambition to provide evidence of the efficacy of two tailored network-based rTMS treatments in mild AD, through the enhancement of connectivity of CEN and DMN. Innovative integrated multi-modal imaging investigations will further enrich this proposal allowing to identify quantifiable markers underlying the clinical impact of rTMS on AD."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '55 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Mini-Mental State Examination score \\>=16, \\<=24\n* Anti-cholinesterase treatment for at least 3 months prior the start date\n\nExclusion Criteria:\n\n* Enrollment in other clinical and pharmacological trials\n* Previous evidence of any other CNS disorder (e.g. epilepsy, infectious diseases, frontotemporal, Parkinson or Pick's disease)\n* History of major psychiatric disorders\n* History of alchol or substance abuse\n* Stress-related skin problems\n* Current consumption of psychiatric medication\n* Presence of metal implants or any implanted electronics"}, 'identificationModule': {'nctId': 'NCT04263194', 'briefTitle': "Network-based rTMS in Alzheimer's Disease", 'organization': {'class': 'OTHER', 'fullName': 'IRCCS Centro San Giovanni di Dio Fatebenefratelli'}, 'officialTitle': "Novel Tailored Network-based rTMS Treatments in Alzheimer's Disease: an Integrated Multiimaging Approach", 'orgStudyIdInfo': {'id': 'GR-2016-02364718'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Default Mode Network (DMN)', 'description': 'The treatment will consist in the individually tailored stimulation of a DMN node (i.e. left inferior parietal lobe).', 'interventionNames': ['Device: rTMS']}, {'type': 'EXPERIMENTAL', 'label': 'Central Executive Network (CEN)', 'description': 'The treatment will consist in the individually tailored stimulation of a CEN node (i.e. left dorsolateral prefrontal cortex).', 'interventionNames': ['Device: rTMS']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'description': 'The treatment will consist in targeting the upper part of the scalp (i.e. CZ) while using a sham rTMS coil.', 'interventionNames': ['Device: Sham rTMS']}], 'interventions': [{'name': 'rTMS', 'type': 'DEVICE', 'description': '25 min of high frequency (20 Hz) repetitive TMS applied at 100% of resting motor threshold (rMT).', 'armGroupLabels': ['Central Executive Network (CEN)', 'Default Mode Network (DMN)']}, {'name': 'Sham rTMS', 'type': 'DEVICE', 'description': 'Placebo intervention will consist in the same procedure but using a sham rTMS coil.', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'locations': [{'zip': '25125', 'city': 'Brescia', 'state': 'Lombardy', 'status': 'RECRUITING', 'country': 'Italy', 'contacts': [{'name': 'Debora Brignani', 'role': 'CONTACT'}], 'facility': 'IRCCS Centro San Giovanni di Dio Fatebenefratelli', 'geoPoint': {'lat': 45.53558, 'lon': 10.21472}}], 'centralContacts': [{'name': 'Debora Brignani', 'role': 'CONTACT', 'email': 'dbrignani@fatebenefratelli.eu', 'phone': '0303501597'}], 'overallOfficials': [{'name': 'Debora Brignani', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'IRCCS Centro San Giovanni di Dio Fatebenefratelli'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'IRCCS Centro San Giovanni di Dio Fatebenefratelli', 'class': 'OTHER'}, 'collaborators': [{'name': 'I.R.C.C.S.
