Non-invasive Stimulation of Brain Networks and Cognition in Alzheimer's Disease and Frontotemporal Dementia — NetCogBs  

Alzheimer's Disease Clinical Trial

Official title:
A Non-invasive, Multimodal Approach to Restore Functional Networks and Cognition in Alzheimer's Disease and Frontotemporal Dementia

Clinical Trial Summary

This pilot study aims to test clinical and connectivity changes following non-invasive stimulation of disease-specific networks in Alzheimer's disease (AD) and behavioral variant frontotemporal dementia (bvFTD). 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.
