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
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.
The rarest kind of Alzheimer's disease, the form that is inherited from parent to child with a cruel 50 percent likelihood, has long been marked by its untapped opportunities. Affected families have made possible both the discovery of the first three
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 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
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
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
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
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
Did you know that if you had a spinal tap for a cerebrospinal fluid-based Alzheimer's diagnosis in Boston, Stockholm, London, or San Diego, the readout would likely be different in each place? And different again this year and next? That's a pro
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
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
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
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
