New ways to detect and treat Alzheimer's disease

17.11.2010
Specific brain changes suggest new diagnostic markers and therapeutic targets

New studies identify brain changes in people with Alzheimer's disease. The results give researchers a greater understanding of the disease and may help at-risk individuals by improving early detection.

New animal research also shows a novel approach to Alzheimer's vaccine design that may avoid dangerous side effects. These new results were reported at Neuroscience 2010, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health.

About 5.3 million people have Alzheimer's disease, according to the Alzheimer's Association. With the aging baby boomer population, Alzheimer's will continue to affect more people worldwide. Better diagnostic techniques may help identify the disease at earlier, potentially more treatable stages.

Today's new findings show that:

People with Alzheimer's disease show structural changes in the caudate nucleus, a brain structure typically associated with movement disorders such as Parkinson's disease, suggesting that the disease produces broader damage in the brain than previously thought (Sarah Madsen, abstract 348.4, see attached summary).

People at risk for Alzheimer's disease exhibit a structural change in portions of the cerebral cortex, which is largely responsible for reasoning, memory and other "higher function" tasks. The findings may help identify those who would most benefit from early intervention (Sarah George, abstract 756.9, see attached summary).

A new vaccine, which was tested in mice, could protect against memory problems associated with Alzheimer's disease without potentially dangerous side effects. The vaccine targeted a non-human protein that may make it a safer alternative to previous vaccine approaches that caused inflammation in human clinical trials (Charles Glabe, PhD, abstract 725.6, see attached summary).

Too many small aggregates of a protein called tau in the brain can directly interfere with memory, according to new animal research. The findings are important because they suggest that tau may be a good target for developing therapies against Alzheimer's and related diseases (Ottavio Arancio, MD, PhD, abstract 527.8, see attached summary).

"Identifying those at risk for Alzheimer's and developing new treatments for nervous system disorders is a social imperative," said press conference moderator Sam Sisodia, PhD, of the University of Chicago, an expert on the cellular biology of proteins implicated in Alzheimer's disease. "These studies are evidence that we're making real progress to overcome this tragic epidemic."

This research was supported by national funding agencies, such as the National Institutes of Health, as well as private and philanthropic organizations.

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
