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
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
Are you curious about trying iPS cell lines to model the disease you care about? Intrigued but nebulous on where the field is at? Ready to grow an iPS line but not sure where to turn? Read Madolyn Rogers's four-part series to learn all about who does
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
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 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
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
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.
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
As populations age worldwide and the number of people with dementia is set to soar over the next few decades, a crisis in eldercare looms. At the same time, the use of personal technology—smartphones, tablets, wearable monitors—is exploding. Can technolog
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 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
