Using Blood Protein Markers for Brain Health Screening

Can a simple blood test be possible to screen for Alzheimer’s disease and other brain conditions? New research discussed at the Alzheimer’s Association International Conference (AAIC) last month suggests that reliable, low cost blood serum analysis for brain biomarkers is a possibility within the next decade or so. Blood tests are an attractive screening option […]

Should Medicare Cover the Cost of Brain Imaging Tests for Alzheimer’s Diagnosis?

I’m at the Alzheimer’s Association International Conference (AAIC) in Boston this week, and one of the most discussed topics is the power of brain imaging tests to detect amyloid beta protein in the brain, one of the main hallmarks of Alzheimer’s disease pathology. Positron Emission Tomography (PET) imaging tests can identify amyloid beta deposits in […]

Detecting Alzheimer’s Disease 20 Years Before Symptoms Appear

A research team at Washington University School of Medicine just published the results of a study that looked at a number of cognitive changes and biomarkers that can be used to predict the risk of Alzheimer’s Disease long before symptoms appear – in some cases up to 20 years before symptom onset. The study, published […]

New Progress on a Blood Test for Alzheimer’s Disease

The PLoS ONE science journal published an interesting study performed by the Brain and Aging Research Program at the University of New South Wales in Sydney, Australia. The study sampled apolipoprotein levels in blood samples from over 600 older adults participating in the ongoing Sydney Memory and Aging Study. Apolipoproteins are proteins that transport cholesterol […]

Privacy and Ethics Challenges on Early Diagnosis of Alzheimer’s Disease

A timely article in the medical journal Neurology speaks to some impending issues that millions of patients and physicians will be facing over the next decade, namely the possible early diagnosis of Alzheimer’s Disease in the pre-clinical phase, before functional cognitive impairment is present. New computerized cognitive testing tools and experimental biomarker tests are bringing […]

Rethinking a Cure for Alzheimer’s Disease

A recent article in Journal of Alzheimer’s Disease discussed several inconvenient facts on the state of Alzheimer’s research, namely that the almost singular focus on amyloid beta protein as the cause of Alzheimer’s Disease (AD) has produced a remarkable string of failures in drug trials that target removal of amyloid beta in the brain. Authored […]

Sports Concussion Testing with Portable EEG

A new study published in the Journal of Head Trauma Rehabilitation points to some interesting work being done using portable EEG systems to monitor sports concussions. The study analyzed results from almost 400 high school and collegiate football players during the 2008-2009 playing season in Milwaukee, WI. A total of 28 players sustained concussions during […]

New Poll Reveals Strong Consumer Interest in Screening for Alzheimer’s and Dementia

A new survey conducted by the Harvard School of Public Health and Alzheimer Europe points to a strong consumer desire for “predictive testing” – the promise of a medical screening test that can gauge the likelihood of a person declining into Alzheimer’s Disease (AD) as they age. Over two thirds of respondents said that they […]
