A Hyderabad-based ICMR-NIN study found that vitamin D and B-complex deficiencies were more common among 570 adults at higher predicted dementia risk in Telangana.
Key highlights
Direct fact
In 2026, the Hyderabad-based ICMR-National Institute of Nutrition (ICMR-NIN) reported that micronutrient deficiencies, especially vitamin D and B-complex vitamins, were linked to higher predicted dementia risk among 570 adults aged 40 to 80 years in Telangana.
Key specifics
- The study covered 570 adults aged 40 to 80 years from rural and urban Telangana.
- Nearly 40% of participants had a higher predicted risk of dementia.
- Deficiencies in vitamin D, B2, B6 and B12 were more common in the higher-risk group.
- Researchers used the CAIDE score and the Montreal Cognitive Assessment to assess dementia risk and cognition.
- The findings were published in The Lancet Regional Health – Southeast Asia with collaborators from Stanford Center for Innovation in Global Health and Karolinska Institute.
Exam lens
Science and health current affairs, study-location-method question type; ICMR-NIN, 570 adults, Telangana, CAIDE score, vitamin D and B2/B6/B12 are the key MCQ anchors. TNPSC may ask which institute linked micronutrient status with dementia prevention.
