Indian scientists develop smartphone tool to detect Alzheimer's early

Scientists at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) in Bangalore have unveiled a smartphone-based diagnostic platform capable of detecting Alzheimer's disease, potentially transforming early diagnosis in resource-limited settings across the country.

The system leverages mobile technology to identify biomarkers associated with Alzheimer's, enabling faster and more accessible screening compared to conventional laboratory-based methods. By converting smartphones into diagnostic devices, the technology addresses a critical gap in India's healthcare infrastructure, where advanced neurological testing remains concentrated in metropolitan centres and specialized facilities.

Alzheimer's disease affects millions globally, with India experiencing a growing burden of neurodegenerative disorders. Early detection remains crucial for disease management and intervention, yet many patients in rural and semi-urban areas lack access to diagnostic facilities. This innovation aims to democratize detection by utilizing devices already widely distributed across the population.

The development represents a significant step toward point-of-care diagnostics in India, aligning with broader efforts to strengthen disease detection capabilities at primary healthcare levels. Researchers indicate the system could facilitate screening programmes and enable healthcare providers to identify at-risk individuals for further clinical evaluation.

The technology is expected to undergo further clinical validation before potential deployment in healthcare settings across India.
