Detecting Alzheimer's disease before symptoms emerge
Long before symptoms of Alzheimer's disease become apparent to patients and their families, biological changes are occurring within the brain. Amyloid plaques, which are clusters of protein fragments, along with tangles of protein known as tau, form in the brain and grow in number, eventually getting in the way of the brain's ability to function. These biological changes can be detected early in…

New insights into early cognitive markers of Alzheimer's
New research led by the University of Hertfordshire, may significantly change the understanding of cognitive processes that are most impaired at very early stages of Alzheimer's disease. The findings could potentially be used to detect the condition at an earlier stage and improve diagnostic accuracy, by creating new cognitive tests that are more sensitive to brain pathology than ones currently…

Bigger Tests: Cancer Drug Might Slow Parkinson's and Alzheimer's
Scientists are hoping that a single drug can treat two devastating brain diseases: Parkinson's and Alzheimer's. The drug is nilotinib, which is approved to treat a form of leukemia.

A protein called PERK - Treating progressive supranuclear palsy
The brain disease “progressive supranuclear palsy” (PSP) is currently incurable and its symptoms can only be eased to a very limited degree. PSP impairs eye movements, locomotion, balance control, and speech. Scientists at the German Center for Neurodegenerative Diseases (DZNE) and the Technical University of Munich (TUM) have now discovered a molecular mechanism that may help in the search…

Molecular Roots of Alzheimer’s
Scientists at Washington University School of Medicine in St. Louis have detailed the structure of a molecule that has been implicated in Alzheimer’s disease. Knowing the shape of the molecule — and how that shape may be disrupted by certain genetic mutations — can help in understanding how Alzheimer’s and other neurodegenerative diseases develop and how to prevent and treat them.

Predict early stages of Alzheimer’s disease
Researchers from Columbia University Medical Center (CUMC), New York State Psychiatric Institute, and NewYork-Presbyterian reported that an odor identification test may prove useful in predicting cognitive decline and detecting early-stage Alzheimer’s disease. Their two studies, presented at the Alzheimer’s Association’s International Conference in Toronto, Canada, suggest that the…

Blood test detects early Alzheimer’s
The cause of Alzheimer’s disease remains unknown. Early diagnosis is currently not possible as clinical symptoms only occur once a large number of neurones in the brain have already been destroyed. There is no treatment available either.
Partners in crime: Stroke and Alzheimer’s disease
New EU-funded project CoSTREAM targets the common mechanisms and pathways of stroke, Alzheimer’s disease to improve disease prevention and treatment, by combining clinical, genetic, epidemiologic, metabolic and radiologic research to develop an organ-on-a-chip in vitro model for the blood-brain connection that will revolutionise drug-development.
First diagnosed case of Alzheimer’s Disease in HIV-positive individual
Georgetown University researchers are reporting the first case of Alzheimer’s disease diagnosed in an HIV-positive individual. The finding in a 71-year-old man triggers a realization about HIV survivors now reaching the age when Alzheimer’s risk begins to escalate.

Another piece in the Parkinson's disease pathology puzzle
An international public-private research consortium has identified and validated a cellular role of a primary Parkinson’s disease drug target, the LRRK2 kinase. This important finding illuminates a novel route for therapeutic development and intervention testing for Parkinson’s, the second most common neurodegenerative disease after Alzheimer’s.

The case of the sticky protein
Proteins are like a body’s in-house Lego set. These large, complex molecules are made up of building blocks called amino acids. Most of the time, proteins fold correctly, but sometimes they can misfold. This misfolding causes the proteins to get sticky, and that can promote clumping, or aggregation, which is the hallmark of several neurodegenerative diseases such as ALS, Alzheimer’s and…
Down syndrome research untangles therapeutic possibilities for Alzheimer's
More than five million Americans are living with Alzheimer's disease (AD). Of them, 400,000 also have Down syndrome. Both groups have similar looking brains with higher levels of the protein beta amyloid.

Researchers retrieve “lost” memories
Retrograde amnesia is the inability to recall established memories. In humans, amnesia is associated with traumatic brain injury, Alzheimer’s disease, and other neurological conditions. Whether memories lost to amnesia are completely erased or merely unable to be recalled remains an open question. Now, in a finding that casts new light on the nature of memory, researchers from the RIKEN-MIT…
