The overarching goal of the THALES project awarded to the University of Athens was to document the linguistic and cognitive symptoms of aphasia, an acquired language disorder after stroke, for speakers of Standard Modern Greek. Furthermore, the research aimed to inform clinical aphasia practice by investigating therapeutic implications. It is important to highlight that this is the first in-depth study on the topic carried out in Greece. It serves as a major step to increase the evidence base of aphasia research and facilitate the translation of the best available evidence into practice for researchers, clinicians, patients and policy makers (e.g., Ministry of Health).
