Introduction to CALM-Brain Repository
CALM-Brain is India’s first comprehensive digital repository dedicated to brain structure data, launched in early 2024 by IIT Madras in collaboration with the Department of Biotechnology (DBT) and Indian Council of Medical Research (ICMR). It currently hosts over 10,000 high-resolution neuroimaging scans, including MRI, fMRI, and DTI modalities, collected from diverse clinical and research settings across India (The Hindu, 2024). The repository aims to expand to 100,000 scans within five years to enable AI-driven predictive models for neurological disorders.
This initiative addresses critical gaps in India’s neurological data infrastructure by creating a centralized platform for neuroinformatics, facilitating precision medicine, and improving diagnostic accuracy. It also aligns with the government’s digital health agenda under the National Digital Health Mission (NDHM).

Constitutional and Legal Framework Governing CALM-Brain
The repository’s operation intersects with multiple legal provisions ensuring ethical data handling and citizens’ health rights. Article 21 of the Indian Constitution implicitly guarantees the right to health, underpinning government initiatives to improve healthcare through technology.
- Biomedical Waste Management Rules, 2016 under the Environment Protection Act, 1986 regulate disposal of biological samples used in neuroimaging studies.
- Information Technology Act, 2000, especially Section 43A, mandates protection of sensitive personal data, ensuring CALM-Brain’s compliance with data privacy norms.
- The National Digital Health Mission (NDHM) framework provides the regulatory and governance structure for digital health data, including interoperability standards and consent management.
Currently, India lacks a unified regulatory framework specifically for neuroimaging data privacy and interoperability, which poses challenges for data sharing and AI integration.
Economic Dimensions of CALM-Brain
India’s healthcare IT market is projected to reach USD 21 billion by 2025, growing at a CAGR of 17.5% (NASSCOM, 2023). Neurological disorders impose a significant economic burden, with treatment costs exceeding INR 50,000 crore annually (ICMR, 2022). CALM-Brain’s potential to reduce diagnostic delays by 30% could save approximately INR 1,200 crore annually in healthcare expenditure.
- Government allocated INR 500 crore for digital health infrastructure in the Union Budget 2024-25, supporting initiatives like CALM-Brain.
- Improved diagnostic accuracy by 25% in pilot studies using CALM-Brain data (IIT Madras, 2024) indicates cost-effectiveness through early intervention.
Institutional Roles and Contributions

Data Insights and Public Health Implications
Neurodegenerative diseases affect approximately 7% of India’s population aged above 60 (ICMR, 2023). India accounts for 12% of global stroke cases with a 17% mortality rate (WHO, 2023). CALM-Brain integrates multi-modal imaging data, enabling better understanding of disease progression and personalized treatment.
- Digital health initiatives using CALM-Brain data have improved diagnostic accuracy by 25%, reducing misdiagnoses and treatment delays (IIT Madras, 2024).
- Expansion to 100,000 scans will enhance AI-driven predictive analytics, crucial for early detection of conditions like Alzheimer’s and Parkinson’s.
