There are already a number of inexpensive new devices that allow doctors in developing nations to image patients' retinas. In order to get a better look at what's going on, though, an optical coherence tomography (OCT) scanner is required – and a cheaper one of those has now also been developed.

MRI is a great tool for diagnosing disease, but it can be costly and cumbersome. Now, engineers at Boston University have developed a new device, small enough for a patient to wear inside the machine, that could boost the signal and provide higher-resolution images at lower magnetic strengths.

An exciting new study from the University of Cambridge is demonstrating how a novel virtual reality navigation test can better predict which patients are in the early stages of Alzheimer's disease compared to other currently used "gold standard" cognitive tests.

A new two-step diagnostic process is claiming to confidently detect Alzheimer's disease nearly a decade before clinical symptoms appear. It's hoped that the method will improve the results of clinical trials by helping better identify patients at the earliest stages of the disease.

For decades, sufferers of chronic fatigue syndrome have battled to prove this illness is not a psychological condition, but in fact an actual biological disease. Now a team has developed a new type of blood test that could offer doctors the first diagnostic tool to identify it.

Nobody likes having blood samples taken, which is why we've seen a number of devices that gather sweat from the skin and then analyze it. An inexpensive new bandage-like biosensor simplifies that concept, as it doesn't incorporate any electronic components.

Because it doesn't show up in either blood tests or brain scans, Parkinson's disease can be frustratingly difficult to diagnose. A new device could help, however, by repeatedly bending the patient's finger. It may make diagnoses easier, and allow treatment to start earlier.

Post traumatic stress disorder, depression and anxiety can all be quite serious conditions, but it's often difficult to determine who may be prone to developing them. New research suggests that in order to find out, we should perhaps look to a person's skin.

A compelling new study has reported that statistically significant differences can be identified in the retinas of patients with Alzheimer's disease. The finding paves the way for a future where the disease could be diagnosed from a simple eye scan before major symptoms appear.

A team of scientists from the University of Illinois at Chicago and Queensland University of Technology in Australia has demonstrated a new, cheap and fast device that can detect floating cancer cells in a tiny blood sample.
