The elderly with mild cognitive impairment (MCI) suffer from weakened ability to recognize faces when compared to healthy elderly people. When trying to memorize, their gaze is also different, suggest Japanese researchers. Alzheimer’s disease, the most ...

Noninvasive eye scan could detect key signs of Alzheimer’s years before patients show symptoms

Cedars-Sinai neuroscience investigators have found that Alzheimer’s disease affects the retina — the back of the eye — similarly to the way it affects the brain. The study also revealed that an investigational, noninvasive eye scan could detect the key signs of Alzheimer’s disease years before patients experience symptoms. Using a high-definition eye scan developed especially for the study, researchers ...

Vitamin B12 Deficiency Sensor Developed to Detect Dementia, Alzheimer Disease in Minutes

In old-age, the frequent occurrence of B12 deficiency could lead to dementia and even Alzheimer’s disease as the body metabolism fails to absorb the vitamin from the diet, requiring an early medical intervention. To help detect B12 deficieny early, Australia’s University of Adelaide researchers have developed a first of its kind optical sensor using a technique called Raman spectroscopy that ...
