Using graphene to detect ALS, other neurodegenerative diseases

The wonders of graphene are numerous — it can enable flexible electronic components, enhance solar cell capacity, filter the finest subatomic particles and revolutionize batteries. Now, the “supermaterial” may one day be used to test for amyotrophic lateral sclerosis, or ALS — a progressive, neurodegenerative disease which is diagnosed mostly by ruling out other disorders, […]

New information on the pathological mechanisms of Alzheimer’s disease

Researchers at the University of Helsinki have discovered a mechanism by which harmful tau protein aggregates are transmitted between neurons. Alongside amyloid plaques, tau aggregates in the brain are a significant factor in the progression of Alzheimer’s disease. Alzheimer’s disease is associated with two neuropathologies: amyloid plaques and tau aggregates, or tau protein accumulated in […]

Losing control of gene activity in Alzheimer’s disease

Pioneering research into the mechanisms controlling gene activity in the brain could hold the key to understanding Alzheimer’s disease and might help identify effective treatments in the future. An international research team led by scientists at the University of Exeter and the University of Essex have uncovered a link between indicators of gene activity and […]

Modifiable dementia risk factor in older adults identified

For older adults, it may seem as though the die is already cast regarding their odds of developing dementia, but new research from the University of Pittsburgh has identified a dementia risk factor among older adults that should be modifiable even well into old age. The study, which draws on data collected from following hundreds […]

Early sleep loss accelerates Alzheimer’s pathology in mice

Lack of sleep during adolescence and early adulthood accelerates Alzheimer’s disease (AD)-related tau pathology, finds a study of male and female mice published in JNeurosci. These results support the importance of establishing healthy sleep habits in early adult life to help stave off progression of neurodegenerative diseases. Using a mouse model of tauopathy, Sigrid Veasey […]

Time to rethink how we diagnose Alzheimer’s disease

With all the focus on Alzheimer disease in recent years as a result of the aging population, what have we learned? A symposium at The North American Menopause Society (NAMS) Annual Meeting in San Diego, October 3-6, will not only review conflicting evidence regarding the best way to diagnose the disease, but also the latest […]

Challenge continues in developing effective drug treatment for Alzheimer’s disease

The results of a large-scale international study involving the treatment of Alzheimer’s disease, which was led and coordinated by researchers at Trinity College Dublin, have just been published this week in a major medical journal, PLOS Medicine. Alzheimer’s disease, the commonest form of dementia, currently affects approximately 34 million people worldwide, with 10.5 million people […]
