Why people with diabetes face higher dementia risk?

In this in-depth conversation, Dr V Mohan, Chairman of Dr Mohan’s Diabetes and Research Centre in Chennai, explained the lesser-known link between diabetes and the brain.

While most people associate diabetes with heart, kidney, or eye complications, Dr Mohan emphasises that diabetes accelerates biological ageing — making the brain age faster than the body. This increases the risk of Alzheimer’s disease, vascular dementia, and early cognitive decline.

In this video, Dr Mohan explains:

• How diabetes accelerates ageing of the arteries and nerves
• Why is dementia risk nearly double in people with diabetes
• Early warning signs: mild memory issues, forgetfulness, behavioural changes
• What MRI scans and blood markers can detect years before symptoms
• Whether good sugar control can slow brain ageing
• How the upcoming study with IISc and the UK Dementia Research Institute aims to detect dementia early
• The ABCD mantra for brain-healthy diabetes management
