Eye scan may detect early signs of Alzheimer's disease

The new test uses an imaging technique, optical coherence tomography angiography (Octa),... For those with Alzheimer's, the same vessels are sparse and lacking in different areas.

In addition a specific layer of the retina was thinner in participants with Alzheimer's. The vessels of people with Alzheimer's disease were less dense and less thick, even when controlling for age, sex and level of education.

It is the largest analysis of its kind to date and adds to growing evidence Octa is a potentially vital tool in the war on dementia.

The researcher explained that the method is still in the early phases of research. "These changes happening in the retina in the eye may actually mirror the blood vessel changes happening in the brain of individual's with Alzheimer's disease".

"The retina is an extension of the brain", Grewal said.

They are connected by way of the optic nerve. The now cureless disease is the sixth-leading cause of death in America. This has led to an increasing focus on prevention.

The peptide known as amyloid-beta has been proven to change prior to visible memory-related issues, and examination of the concentration of the amyloid-beta in the spinal fluid can provide an indication of the risk of Alzheimer's disease years before it can occur. Results could be helpful in the fight against Alzheimer's disease.

YG ends contract with BIGBANG's Seungri in wake of scandal
A second K-pop star has dramatically quit the music business, in a growing industry sex scandal. The reason? A prostitution scandal that has gotten so "big", it has become too hard to handle.

It would also give patients time to plan for the future with their families - while they still have their faculties, said the U.S. team.

Dr. Fekrat believes that if more people in the earlier stages of Alzheimer's could be recruited into clinical trials, there is a bigger potential for better treatments to be discovered.

Diagnosing the condition at present involves a brain scan, a spinal tap to analyse cerebrospinal fluid or, more frequently, a doctor assessing symptoms. Virginia was later diagnosed with Alzheimer's disease. "Our work is not done".

In the past, some small studies have suggested that there would be differences "in both neuronal and microvascular retinal measures between those with and those without Alzheimer's disease", said Alison Abraham, an associate professor of ophthalmology and director of the Wilmer Eye Institute Biostatistics Center at the Johns Hopkins School of Medicine.

The cells of the retina convert light signals coming into the eye into neural signals the brain can interpret.

They looked at the retinas of 200 people using a new non-invasive technology that takes high-resolution images of the retina. This means journalists are losing the ability to hold the rich and powerful to account. "Every night after dinner we had a conversation", her sister recalled.
