Assessment and Modulation of Cortical Gamma Synchrony to Predict and Improve Stroke Recovery
Assessment and Modulation of Cortical Gamma Synchrony to Predict and Improve Stroke Recovery
In the last decades, the research in neuroimaging-informed stroke prognosis and treatment has had a little clinical impact, often because of the costs of bringing complex procedures to the bedside. Cerebral stroke remains the leading cause of disability, with 65% of survivors chronically impaired at 6 months. Gamma synchrony (GS) is a fundamental mechanism of cortical function and can be estimated and modulated in a simple, inexpensive, and reliable way. It has provided valuable and cost-effective guidance in several neuropsychiatric conditions. In previous studies, we developed simple yet robust methods for assessing and manipulating GS and proved its relationship with clinical impairment in preliminary data.
The aim of the present project is to predict and improve stroke recovery by leveraging cortical mapping and modulation of GS via transcranial alternating current stimulation (tACS), a safe and inexpensive technique. The project capitalizes on technology readily available to the Italian national health system.
The project will consist of 3 Work Packages (WPs):
The participants in this study will be 140 stroke patients rehabilitated at IRCCS San Camillo hospital. 80 will participate in the WP1 and the WP2, while 60 will participate in the WP3 study. In WP1, data will also be collected on 80 healthy volunteer participants, approximately the same age as the patients.
