In addition to neuronal loss, dysfunction in brain network connectivity has been identified as a correlate of cognitive deficits in neurodegenerative and post-traumatic brain injury states. Transcranial alternating current stimulation (tACS) has been suggested as a promising, non-invasive, method of normalizing network connectivity and hence improving cognition, notably memory. This study will examine the efficacy of tACS at improving working memory performance in patients with neurodegeneration and its correlation to changes in network connectivity, based on functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) imaging data.
