Can you get dementia from long-term exposure to traffic noise?

Can you get dementia from long-term exposure to traffic noise?

Author: The Hindu August 25, 2026 Duration: 39:07
Road traffic noise is a major environmental pollutant. Indian cities are cacophonous. They are not designed to insulate residents from sustained exposure to traffic noise. A new research paper has found a worrying link between traffic noise exposure and dementia, and also cognitive impairment. The paper, titled ‘Association of road traffic noise exposure with dementia or cognitive impairment – A systematic review of longitudinal cohort studies’, has been co-authored by Emil Basil Scaria and Nisha Dhanda, and was published on PLOS Global Public Health earlier this year.  We speak with the lead author of the study. Guest: Emil Basil Scaria, a public health researcher and physician based in Dubai Host: G. Sampath Edited and produced by Sharmada Venkatasubramanian Learn more about your ad choices.

Each week, the journalists at In Focus by The Hindu select one pressing story from the news cycle and slow it down. Rather than a rapid headline, you’ll hear a thoughtful conversation that unpacks the layers behind an event-the historical precedents, the economic forces, the political nuances, and the human impact. This podcast relies on conversations with reporters who have been on the ground and specialists who have spent years, sometimes decades, studying a particular issue. The result is a clearer, more substantive understanding of what’s happening in India and around the world. You might explore the roots of a regional conflict one episode, and dive into the complexities of a new environmental policy the next. It’s designed for anyone who feels that the daily news skim leaves too many questions unanswered. Tune in for a consistent, deep-dive format that prioritizes context over instant reaction, making sense of the week’s most significant developments through careful analysis and expert insight.
