MRI elastography: ground-breaking new way to see extremely fast neuronal activity in the brain It is magnificent how fast the human brain operates. In a fraction of a second our  neurons are activated, creating thoughts and reactions to stimuli. The speed at which radiologists can non-invasively  follow brain function using  MRI , however, is...Read more

New research finds that, among patients with established diagnoses at a memory disorder clinic, [18F]flortaucipir positron emission tomography (PET) was able to discriminate Alzheimer's disease from other neurodegenerative diseases. The accuracy and potential utility of this test in patient care require further research in clinically more representative...Read more

The effort to find ways to detect and diagnose preclinical Alzheimer’s disease (AD) has taken a big step forward with the use of positron emission tomography (PET), a “nuclear medicine” for imaging processes in the body, when PET is used with a special ‘tracer’ that binds to the amyloid plaques in the brain that are a characteristic cause of...Read more

While changes in cognitive abilities may not be severe enough to disrupt daily life, a clinical diagnosis of mild cognitive impairment (MCI) indicates an increased risk of eventually developing Alzheimer’s disease or another type of dementia. In a paper published in the Journal of Alzheimer’s Disease , researchers at University of California...Read more

A buildup of plaque and dysfunctional proteins in the brain are hallmarks of Alzheimer’s disease. While much Alzheimer’s research has focused on accumulation of the protein amyloid beta, researchers have begun to pay closer attention to another protein, tau, long associated with this disease but not studied as thoroughly, in part, because scientists...Read more

Researchers in Sweden have found that an antibody gives more exact information than regular radioactive tracers used in PET brain scans, which could lead to more effective diagnosis of early onset Alzheimer’s disease and improvements in monitoring the effects of medication. Counting over 100,000 people, Alzheimer’s is the most common dementia...Read more

A noninvasive retinal imaging device, created at Cedars-Sinai, has potential for early detection of changes that later occur in the brain and are associated with Alzheimer's disease, according to preliminary results of a clinical trial performed in Australia. The new optical imaging tool has been shown to detect changes that occur 15-20 years before...Read more

According to a study published online in the journal Radiology, the presence of a gene variant in people with mild cognitive impairment (MCI) is associated with accelerated rates of brain atrophy. Research was focused on the gene apolipoprotein E (APOE), known as the most important genetic factor in non-familial Alzheimer’s disease (AD). Jeffrey...Read more

Highly educated individuals with mild cognitive impairment that later progressed to Alzheimer’s disease cope better with the disease than individuals with a lower level of education in the same situation, according to research published in the June issue of The Journal of Nuclear Medicine. In the study “Metabolic Networks Underlying Cognitive Reserve...Read more

Researchers in the U.S. have used a brain-imaging tool and stroke risk assessment to identify signs of cognitive decline early on in individuals who don't yet show symptoms of dementia. The connection between stroke risk and cognitive decline is well established. Individuals with higher stroke risk, as measured by factors like high blood pressure,...Read more
