Abnormal hyperactivation in the brain may be an early sign of Alzheimer’s — ScienceDaily

Abnormally hyperactive areas in the brain may help better predict the onset of Alzheimer’s disease, according to findings of a research team led by Université de Montreal psychology professor Sylvie Belleville, scientific Director of the Institut universitaire de gériatrie de Montréal research centre. Hyperactivation could be an early biomarker of Alzheimer’s disease, the researchers say […]
Memory may be preserved in condition with brain changes similar to Alzheimer’s disease — ScienceDaily

Primary progressive aphasia is a rare neurodegenerative condition characterized by prominent language problems that worsen over time. About 40% of people with the condition have underlying Alzheimer’s disease. But a new study has found that people with the condition may not develop the memory problems associated with Alzheimer’s disease. The study is published in the […]
How a very ‘sociable’ protein can hold clues about Alzheimer’s origin

Using the ESRF cryo-electron microscope and Small Angle X-ray Scattering at the ESRF’s beamline BM29, the researchers managed to decipher the role of ECSIT in mitochondrial activity. Credit: ESRF/Stef Candé An international team of scientists led by the ESRF, the European Synchrotron, have found how the ECSIT protein dictates the behavior of proteins linked to […]
Studies could lead to new ways to enhance memory for those with traumatic brain injury or Alzheimer’s disease — ScienceDaily

Two studies led by UT Southwestern researchers shed new light on how the brain encodes time and place into memories. The findings, published recently in PNAS and Science, not only add to the body of fundamental research on memory, but could eventually provide the basis for new treatments to combat memory loss from conditions such […]
New tests identify early changes in Alzheimer’s disease before symptoms appear — ScienceDaily

Researchers at the University of Gothenburg in Sweden, together with their colleagues at the Barcelona Beta Research Centre in Spain, the University Medical Centre in Ljubljana, Slovenia, and the University of Paris, have found new forms of tau protein that become abnormal in the very early stages of Alzheimer’s disease before cognitive problems develop. The […]

Early signs of Alzheimer’s disease in people with Down’s syndrome

Researchers at Karolinska Institutet in Sweden have studied the incidence and regional distribution of Alzheimer’s disease biomarkers in the brains of people with Down’s syndrome. The results can bring new possibilities for earlier diagnosis and preventive treatment of dementia. The study is published in Molecular Neurodegeneration. While medical advances and improvements of life quality have […]
Diabetes increases neuritic damage around amyloid plaques in Alzheimer’s disease

New research from the University of Eastern Finland explores the role of diabetes in the cellular and molecular changes underlying Alzheimer’s disease (AD). In an AD mouse model, diabetes induced through a diet rich in fats and sugars weakened the accumulation of microglial cells around amyloid plaques and increased the formation of neuritic plaques with […]
New potential clues in diagnosing, treating Alzheimer’s — ScienceDaily

A study led by the Cedars-Sinai Department of Neurosurgery has identified certain regions in the retina — the lining found in the back of the eye — that are more affected by Alzheimer’s disease than other areas. The findings may help physicians predict changes in the brain as well as cognitive deterioration, even for patients […]
Link between Alzheimer’s disease and gut microbiota is confirmed

Alzheimer’s disease is the most common cause of dementia. Still incurable, it directly affects nearly one million people in Europe, and indirectly millions of family members as well as society as a whole. In recent years, the scientific community has suspected that the gut microbiota plays a role in the development of the disease. A […]
