Specific Triazine Herbicides Induce Amyloid-β42 Production

A new study led by Laurent Meijer, at ManRos Therapeutics, and collaborators shows that some herbicides (triazines) trigger enhanced in vitro production of the Aβ42 over Aβ40 amyloid peptides in various cell lines. This suggests that some products from the ‘human chemical exposome’ (HCE) (estimated to be over 85,000 products) may contribute to the increased production of Aβ42 over Aβ40 characteristic of Alzheimer’s disease (AD). In addition, some of these products might be turned into pharmacological tools to develop a chemically-induced animal model of AD (in contrast with the currently used genetic, recombinant mice models).

Efficacy and Safety of Crocus Sativus L in Patients with Mild Cognitive Impairment: One Year Single-Blind Randomized, with Parallel Groups, Clinical Trial

Crocus Sativus

Greek researchers and clinicians demonstrated the potential of Crocus Sativus L. (saffron) as a therapeutic pharmaceutical natural compound for older adults with amnestic Mild Cognitive Impairment (aMCI). MCI is a condition that often predates Alzheimer’s disease (AD) and is characterized by memory loss and inability to execute complex Activities of Daily Living. While there is no treatment for MCI and symptomatic only treatment for AD, the global effort against cognitive disorders is focused on early detection and management of AD at the stage of MCI.

Midlife physical activity is associated with better cognition in old age

Journal of Alzheimer's Disease

A long-term follow-up study of 3050 twins from the Finnish Twin Cohort has shown that midlife, moderately vigorous physical activity is associated with better cognition at old age. The association was statistically independent of midlife hypertension, smoking, education level, sex, obesity and binge drinking. This suggests that the beneficial influence of physical activity on the brain and cognition is not solely based on decreasing vascular risk factors.

Markers associated with Alzheimer’s and Parkinson’s diseases are present in Mexico City children chronically exposed to concentrations of fine particulate matter PM2.5 above the current EPA USA standards

Air pollution over Mexico City

A new study by researchers at the Universities of Montana, Valle de México, Boise State, Veracruz University, Médica Sur, Centro de Ciencias de la Atmósfera, UNAM, Hospital Regional de Alta Especialidad, Ciudad Victoria, Hospital de Especialidades #14, IMSS, Centre Hospitalier Universitaire, Hôpital de Hautepierre and AJ Roboscreen GmbH heightens concerns over the detrimental impact of fine particulate matter PM2.5 on CSF markers associated with Alzheimer and Parkinson’s diseases in children ages 11.9±4.8 years. These findings are published in the Journal of Alzheimer’s Disease.

Subjective Cognitive Decline and risk of future AD dementia - results from a German multi-center study highlights the importance of temporal consistency

Steffen Wolfsgruber

A new study, based on longitudinal data from the German Study on Aging, Cognition and Dementia in Primary Care Patients (AgeCoDe), suggests that temporal stability versus instability of an individual’s report of subjective worsening of cognition over time plays an important role with regard to whether such experiences are associated with future dementia risk. These findings, which will be published in the Journal of Alzheimer's Disease 54(3), add to a constantly growing strand of research on the phenomenon of “Subjective Cognitive Decline” (SCD) in Alzheimer’s Disease (AD).

Study Reveals Association between Physical Function and Neurological Disease

Galit Weinstein

A new study, based on data from the Framingham Heart Study (FHS) suggests a simple test of physical functioning may be able to help physicians identify individuals who are at a higher risk for developing Alzheimer’s disease and stroke. These findings, which appear in the Journal of Alzheimer’s Disease, provide hope that there are easy-to-test clinical markers that will help physicians identify individuals who are at increased risk for common age-related neurological diseases.

Artistic skills emerge as dementia progresses

Olivier Piguet

A new study by researchers at Neuroscience Research Australia (NeuRA) has identified the emergence of positive changes that occur after a person has been diagnosed with dementia. The first of its kind, the study has confirmed anecdotal evidence that creative skills such as painting, drawing, or singing – which were not previously evident in an individual – can emerge or improve in people with Alzheimer’s disease and frontotemporal dementia.
