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
With the nation at war for eight continuous years, and awareness of the dangers of sports concussions on the rise, a new priority—and opportunity—are taking shape for neurodegenerative disease researchers. In a time of austere budgets, the Department of D
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
If you find it hard to keep up with Facebook, LinkedIn, and other social networks, spare a thought for the brain. With 100 to 500 trillion synaptic connections, the human brain dwarfs all of them. How do those connections work to formulate thought, recall
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 endocytic receptor SORL1 has come to fruition both literally and figuratively. An interactive diagram of the 2,214 amino acid behemoth—filled with findings about hundreds of rare variants—is live for viewing on the Alzforum Mutations database. A handf
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
When the first human genome sequence was finished in 2003, it quickly became clear that its seemingly unending stream of letters was not enough to comprehend what makes people tick. All the moving parts that bring the DNA code to life needed to be underst
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
Move over, genome, transcriptome, proteome. The latest ome aims to map every metabolite linked to human health and disease. Metabolomics, although still a nascent field, offers hope for biomarkers and treatments in neurodegenerative disease. The field
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
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
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
