Researchers have tied sleep to clearance of waste products such as excess Aβ. New research suggests this clearance may be driven by a change in the extracellular ion composition, which swells the interstitial fluid. Other work finds an essential role for
Banked brain tissue enables crucial advances in the understanding and treatment of degenerative disorders. As appreciation of the many different variants of neurodegenerative disease is growing, well-preserved tissue is in more demand than ever. Are the b
Alzforum readers who follow the science of preclinical Alzheimer's and prevention may have heard about three independent but complementary programs that together are laying the groundwork for secondary prevention trials across the spectrum of rare to
The Alzheimer's Disease Neuroimaging Initiative is the most expensive AD study the NIH has ever funded. Expectations are that it will speak with the authoritative voice of a 58-center, three-year observation of 819 research participants above a curre
U.S. guidelines for assessing Alzheimer's disease (AD) neuropathology are getting a much-needed facelift. The existing ones, in place since 1997, had fallen out of step with the current understanding of AD as a disease with a long preclinical stage.
A contentious hypothesis about where and how Parkinson’s disease starts off is gaining ground as new studies provide clues in its support. Neuroanatomists Heiko Braak and Kelly Del Tredici, both at the University of Ulm in Germany, have described the dist
In the absence of truly effective treatments, and in the presence of a rapidly growing, dementia-prone population of elders, it's perhaps no surprise that people are increasingly open to products claiming even the slightest hint of promise, however u
With the holidays upon us, are your nerves fraying under the combined pressures of work deadlines, shopping, decorating, and entertaining? Now may be a good time to sit back and consider the effects of stress on the brain. Stress per se is not a cause of
In this series, ARF takes stock of deep-brain stimulation after more than a decade of life-altering procedures, In deep brain stimulation, surgeons implant wires into the brain and hook them up to a pacemaker-like stimulator implanted in the chest, which
Alzforum readers might be forgiven for thinking all microglia do is act prominently, if mysteriously, in Alzheimer's pathogenesis. Not so. A recent flurry of papers shows that microglia can match themselves specifically to GABA synapses. They can rev
For families with autosomal-dominant neurological conditions, the fear of passing on the disease to their children looms large. Now, people at this highest genetic risk can ensure that they have healthy children by undergoing in vitro fertilization follow
In the Finnish city of Kuopio, neurosurgeons collaborate with neurophysiologists and molecular and cellular biologists to make frontal cortex, dura, intraventricular CSF, skin, fat, and other tissue from hydrocephalus patients available for research purpo
Two weeks after the FDA gave the nod to aducanumab, the aftershocks continue to reverberate. Critics are lambasting the agency, three members of its advisory committee resigned, and the drug’s cost has ignited calls for pricing reform. Meanwhile, Alzheime
If you listen to National Public Radio, watch TV, or surf the Web, chances are you have come across commercials enticing you to “improve your memory” and “unlock your inner genius” with “brain training developed by neuroscientists.” In search of solid ev
