January 20, 2026, New Delhi: Test for early detection of Alzheimer’s Researchers announced a promising AI-powered blood test that can find Alzheimer’s disease years before clinical symptoms appear. This brought India back into the scientific spotlight. This breakthrough could change the way cognitive health is tracked in the country, especially for older people who are at risk of dementia.

The new test was made by working together with top Indian medical institutions and technology partners. It uses machine learning algorithms and blood biomarkers to find early signs of the neurodegenerative disorder. This is a big improvement over traditional cognitive tests and brain imaging methods.
Why it’s important to find out early
Alzheimer’s disease is a brain disorder that gets worse over time and makes it harder to remember things, think clearly, and act normally. Cognitive tests and brain scans are two examples of current diagnosis methods that often only find the disease after symptoms become clear. Experts say that early detection is very important because it lets doctors and carers step in sooner, which leads to better outcomes for patients and slows the progression of the disease through lifestyle changes, medication management, and planning for support.
The World Health Organisation (WHO) says that dementia is becoming more common around the world as people get older. India, which has a lot of older people, has a lot of problems with healthcare screening and long-term care infrastructure. (W.H.O.)

How the AI-Powered Test Works
The new blood test looks for patterns in large datasets that are linked to early pathological changes in the brain using machine learning models. Researchers say that the test looks at combinations of proteins, genetic markers, and metabolic indicators that other tests might miss.
Dr. Ayesha Kapoor, a neurologist who worked on the study, said that the AI model has been trained to pick up on small changes in blood samples that are linked to early cognitive decline. “This method helps us find people who are at risk much earlier than regular clinical tools,” she said. Experts say that the test is not yet a definitive diagnosis tool, but it is an advanced screening tool that can lead to more detailed monitoring and follow-up neurological evaluation.
Effects on healthcare and public policy
This new technology is seen by healthcare workers as a step towards personalised dementia care in India. By finding at-risk people earlier, doctors will be able to make care plans that are specific to each person, suggest ways to avoid problems, and involve families and carers in making plans for effective support systems.
Policy researchers and public health advocates have also welcomed the news and are calling on government agencies and private health providers to use similar screening technologies in national health programs. Families and the healthcare system have a lot to deal with when someone has Alzheimer’s disease. Early detection technologies could help lower the costs of long-term care by slowing the progression of the disease.
Limitations and the Future
Even though it looks promising, the AI-enabled blood test is still being tested in clinical settings and is not yet widely available as a standard diagnostic tool. Researchers say that before the test can be used in all of India’s healthcare networks, it needs to be tested in larger studies, get regulatory approval, and be shown to be cost-effective.
International studies, on the other hand, have shown that similar AI-based diagnostics can greatly increase the rate of early detection. This gives hope that India could soon make advanced screening widely available, especially in urban healthcare centres and specialised memory clinics.
Experts think that as technology gets better, AI integration in diagnostic pathways could become an important part of screening for older people, making life better for millions of people and lowering the cost of caring for people with dementia.
