British-Pakistani Scientist Develops AI Eye Scan for Dementia Detection

A Qatar-based British-Pakistani scientist has developed an artificial intelligence-powered eye scan capable of detecting dementia in its early stages, marking a significant advance in non-invasive neurological diagnostics. The technology analyses retinal patterns to identify biomarkers associated with cognitive decline, offering a potential pathway for mass screening before clinical symptoms emerge.

The development carries particular significance for populations in South Asia and the Middle East, where dementia often goes undiagnosed until advanced stages due to limited access to specialised neurological facilities. An eye scan-based screening tool could be deployed at primary care level with minimal infrastructure requirements.

The scientist, operating out of Qatar, developed the system by training machine learning models on large retinal imaging datasets, cross-referencing ocular indicators with confirmed dementia diagnoses. The AI model demonstrated high sensitivity in identifying at-risk individuals during validation trials.

Early dementia diagnosis remains one of the most pressing challenges in global healthcare, as current gold-standard tests are invasive, expensive, or require advanced imaging equipment. If validated at scale, this technology could reshape screening protocols across developing and developed health systems alike. The research adds to a growing body of work linking retinal imaging to systemic neurological conditions.
