Confirmation of the smell test for Alzheimer’s

Alzheimer; News from the web:

Two studies released at an international Alzheimer’s meeting Tuesday suggest doctors may eventually be able to screen people for this form of dementia by testing the ability to identify familiar odors, like smoke, coffee and raspberry.

In both studies, people who were in their 60s and older took a standard odor detection test. And in both cases, those who did poorly on the test were more likely to already have — or go on to develop — problems with memory and thinking.

And thanks to a new imaging system we can see now exactly how.

Researchers at Yale University have led development in to a new type of brain scan designed to detect changes in synapses associated with common brain disorders. Until now, researchers have only be able to detect these changes during autopsies, but by combining a Positron Emission Tomography (PET) scan with a new type of injectable tracer, Yale radiology and biomedical imagining professor Richard Carson was able to measure the synaptic density in a living brain.

Cambridge researchers have identified — and shown that it may be possible to control — the mechanism that leads to the rapid build-up of the disease-causing ‘plaques’ that are characteristic of Alzheimer’s disease.

Vaccine for Alzheimer’s disease could be trialed in humans within the next 3-5 years, after researchers from the United States and Australia have uncovered a formulation that they say successfully targets brain proteins that play a role in development and progression of the disease.

Look in the eyes to find Alzheimer’s

Could it be possible to detect Alzheimer’s disease in the early stages with just an eye exam? That’s the possibility researchers are floating after they were able to spot signs of Alzheimer’s in the retinas of mice using a special, non-invasive camera.
