Ahmedabad: Researchers from IIT-Gandhinagar and AIIMS New Delhi, along with other institutions, have developed a digital tool designed to transform how post-stroke language disorders are diagnosed in India.
In resource-constrained settings, early diagnosis remains difficult due to expensive neuroimaging and time-consuming pen-and-paper evaluations.
Aphasia — a condition affecting speech production and comprehension caused by brain damage — impacts nearly one-third of stroke survivors, according to experts. Researchers said that the platform successfully distinguished post-stroke patients from healthy individuals in clinical testing. Crucially, its acoustic task module accurately differentiated between aphasic and non-aphasic stroke survivors by detecting subtle processing delays and physiological stress markers. The study ‘Computerized Platform in Hindi Language: Exploring Its Use in Aphasia Screening’ by Paromita Mitra, Shipra Kethwalia, Rhythm Makkar, Ruchita Hazrati, Rahul Chhatlani, Geetesh Kumar Singh, Ashima Nehra, and Uttama Lahiri was published in IEEE Journal of Translational Engineering in Health and Medicine.
