Researchers at Boston University (BU) have used computer simulations of the brain to predict language recovery in stroke survivors.
The research group is currently working to better comprehend how language and speech are processed in the brain and how best to rehabilitate and aid language recovery in people who have lost their ability to communicate as a result of brain damage caused by brain injuries such a stroke, or trauma.
This type of language loss is called aphasia, which is a long-term neurological disorder triggered by injury to the part of the brain accountable for language production and processing. This disorder affects over a million people in the US alone.
“It’s a huge problem,” said Swathi Kiran, director of BU’s Aphasia Research Lab, and College of Health and Rehabilitation Sciences. “It’s something our lab is working to tackle at multiple levels.”
Over the last decade, Kiran’s team have been observing the brain and analysing how it changes as people’s language skills improve with speech therapy. They have now established a novel technique to predict a person’s capacity to improve before starting therapy.
The researcher’s findings have been reported in Scientific Reports and outline how BU scientists along with collaborators at the University of Texas at Austin have been able to predict language recovery in Hispanic patients who speak both English and Spanish fluently – a group of aphasia patients particularly at risk of long-term language loss – by utilising advanced computer models of the brain. They say that this groundbreaking development could have transformative impacts in the field of speech therapy and for stroke survivors impacted by aphasia.
