  "account": "After a stroke, the brain regions not directly affected by the injury may exhibit signs of accelerated aging. This can lead to aphasia, a language disorder that varies in severity and treatment prognosis. Researchers at the University of South Carolina Floyd School of Medicine investigated how aging in uninjured brain areas relates to aphasia severity and recovery following treatment.\n\nUsing an online system trained on extensive brain aging datasets, the researchers measured how each individual's brain structure diverged from typical aging patterns in those without a stroke history. Among 188 stroke survivors, structural aging patterns in the unaffected hemisphere of the brain were linked to aphasia severity, independent of lesion size or location. Moreover, pretreatment patterns of brain aging predicted language improvement six months after speech therapy combined with noninvasive brain stimulation.\n\nThe study, published in JNeurosci, offers a framework to connect normal aging models with post-stroke severity and treatment outcomes. This could potentially inform more targeted brain rehabilitation strategies. The lead researcher, Nicholas Riccardi, noted that recovery potential after a stroke depends on the overall health of the brain, which can be influenced by factors like cardiovascular health. Additionally, the researchers utilized a single routine scan and a free online tool to reach various clinical and research settings, making their findings accessible.",
  "summary": "After a stroke, even areas of the brain not directly affected by the injury can show signs of accelerated aging. Stroke can also lead to aphasia, a language disorder that varies widely in severity and treatment outlook. In a new study in JNeurosci, Nicholas Riccardi, Leonardo Bonilha and colleagues at the University of South Carolina Floyd School of Medicine examined how aging in uninjured areas…",
