Alzheimer's: What Is Really in Your Control?

Credit: Thinkstock  When it comes to Alzheimer's Disease (AD), the sad reality is that there is no cure. But a significant number of people have an increased risk due to genetics, and everyone has an increased risk as they age.  According to the Alzheimer’s Association, of the more than five million Americans with Alzheimer's, approximately 200,000 individuals develop the disease before age 65 (younger-onset Alzheimer's...

Publication date: Available online 24 June 2019Source: Biosensors and BioelectronicsAuthor(s): Haixin Qin, Xue Gao, Xiaoyan Yang, Wei Cao, Shufeng LiuAbstractDevelopment of a simple, cost-effective and sensitive biosensing strategy is highly desirable to advance the applications in Alzheimer's disease diagnosis. In this paper, we present a simple, label-free and signal-on electrochemiluminescence (ECL) aptasensor for the detection of amyloid-beta (Aβ) peptide using luminol as ECL emitter and in-situ generated reactive oxygen species (ROS) as coreactant via catalytic reaction between Cu2+-Aβ and the dissolved O2 i...

Authors: Perani D, Iaccarino L, Lammertsma AA, Windhorst AD, Edison P, Boellaard R, Hansson O, Nordberg A, Jacobs AH, IMBI Project Abstract Recent studies in neurodegenerative conditions have increasingly highlighted that the same neuropathology can trigger different clinical phenotypes or, vice-versa, that similar phenotypes can be triggered by different neuropathologies. This evidence has called for the adoption of a pathology spectrum-based approach to study neurodegenerative proteinopathies. These conditions share brain deposition of abnormal protein aggregates, leading to aberrant biochemical, metabolic, funct...

Authors: Mashour GA, Frank L, Batthyany A, Kolanowski AM, Nahm M, Schulman-Green D, Greyson B, Pakhomov S, Karlawish J, Shah RC Abstract Unexpected cognitive lucidity and communication in patients with severe dementias, especially around the time of death, have been observed and reported anecdotally. Here, we review what is known about this phenomenon, related phenomena that provide insight into potential mechanisms, ethical implications, and methodologic considerations for systematic investigation. We conclude that paradoxical lucidity, if systematically confirmed, challenges current assumptions and highlights the...

The brain is an energy-hungry organ, and the supply of oxygen and nutrients to brain tissue is vital to its function. This is one of the reasons why cardiovascular disease contributes to neurodegeneration. Researchers know that cells that wrap small blood vessels in the brain, called pericytes, tend to become dysfunctional or die in later life, another of the cellular casualties of the damage of aging. This causes greater constriction of the blood vessels, reducing the blood flow to tissues. Researchers here provide evidence for this to be a consequence of the aggregation of amyloid-β, characteristic of the early stag...

(Florida Atlantic University) Could artificial intelligence be the solution for detecting and managing a complex condition like Alzheimer's disease? A team of researchers thinks so. They employed a novel application of supervised machine learning and predictive modeling to demonstrate and validate the cross-sectional utility of MemTrax as a clinical decision support screening tool for assessing cognitive impairment. They introduce supervised machine learning as a new approach and value-added complementary tool in cognitive brain health assessment and related patient care and management.
