CALM-Brain Repository

* CALM-Brain is a first-of-its-kind digital repository in India that compiles data on brain structure, function, and psychiatric disorders.
* It has been developed through a collaboration between National Institute of Mental Health and Neurosciences and National Centre for Biological Sciences under the Rohini Nilekani Centre for Brain and Mind.
* The repository is open-source, allowing clinicians and researchers to access and analyse data for scientific studies.
* It is based on Indian patient data, addressing the under-representation of Indian populations in global mental health research.
Key Features of CALM-Brain
* The repository contains multi-modal data, including clinical, neuroimaging, behavioural, and genetic information.
* It focuses on five major psychiatric disorders: addiction, bipolar disorder, dementia, obsessive-compulsive disorder (OCD), and schizophrenia.
* The dataset integrates advanced techniques such as Functional Magnetic Resonance Imaging (fMRI), Near Infrared Spectroscopy (NIRS), electroencephalogram (EEG), observations of cognition, eye-tracking, genetic analyses of blood samples and clinical assessments.
* It is linked to a biorepository of stem cells, enabling deeper biological research into psychiatric illnesses.
* The database is longitudinal, meaning it tracks individuals over time to study disease progression.
* It includes data from over 2,700 participants across more than 1,100 families, enabling family-based analysis.

Significance of the Repository
* Experts state that the complexity of the human brain requires large-scale and multi-level data analysis to understand psychiatric disorders effectively.
* Applying modern data analysis techniques to such datasets can help bridge gaps between biological, behavioural, and clinical understanding.
* Furthermore, the repository will help identify biological markers that cut across traditional diagnostic categories, improving disease classification.
* The availability of family-based and population-specific data can accelerate discovery and improve preventive and therapeutic strategies.
* CALM-Brain addresses the limitation of global datasets, which are largely focused on Western populations and isolated studies.

Implications for Mental Health Research and Treatment
* Experts state that the repository can significantly improve early diagnosis and understanding of disease onset and progression.
* Insights from the data can help develop personalised and patient-specific treatment strategies.
* Studying Indian population data will enable context-specific healthcare solutions suited to local conditions.
* Large-scale collaborative projects demonstrate the importance of multi-institutional cooperation in scientific research.
* Sustained efforts are required to maintain and expand longitudinal databases, as the process require continuous data collection and coordination.
