Recent Developments in Amyloid Imaging

The use of positron emission tomography (PET) imaging to diagnose Alzheimer’s disease (AD) appears to be closer to becoming a clinical tool, based on results from two articles published online in the Archives of Neurology. In one study, Adam S. Fleisher, M.D., from Banner Alzheimer’s Institute in Phoenix, and colleagues, evaluated PET imaging using the tracer florbetapir F 18. The study population included 68 individuals with probable Alzheimer’s disease, 60 individuals with mild cognitive impairment, […]

A Potential Blood Test for Alzheimer's Disease

Oxidation and free radical damage are natural occurrences as our bodies are subjected to toxins and stressors from everything we encounter throughout our lifespan. When oxidation occurs, our bodies respond in the best way they know how: they reach for protective resources from within our cells to combat the damage and maintain our health. If these resources are unavailable, inflammation will occur. The processes of oxidation, free radical production and cell damage are thought to […]

New Guidelines for Diagnosing Alzheimer's: What Do They Mean for You?

For the first time in 27 years, new criteria and guidelines for the diagnosis of Alzheimer’s disease have been published by three expert workgroups spearheaded by the Alzheimer’s Association and the National Institute on Aging (NIA) of the National Institutes of Health (NIH). If you have been diagnosed with Alzheimer’s or have a loved one with the disease, you may be asking, what does this mean for me? In the short term, the new guidelines […]

Studies Reveal Very Early Cognitive Declines with Familial Alzheimer's Disease

Last month, researchers Francisco Lopera and colleagues reported in the journal Lancet Neurology that they were able to capture a clear decline in cognition starting in people’s early 30s in the largest-known population with autosomal-dominant (inherited) Alzheimer’s disease. They define an earlier disease stage prior to what is called pre-MCI, in effect pushing the line of detectability back toward younger ages by some four years. Two other papers go in the same direction. Last year […]

A New Method to Test for Alzheimer's Disease?

Using a new technology that relies on thousands of synthetic molecules to fish for disease-specific antibodies, researchers have developed a potential method for detecting Alzheimer’s disease with a simple blood test. The same methodology might lead to blood tests for many important diseases, according to the report published by Thomas Kodadek’s group at the Scripps Research Institute in the January 7th issue of the journal Cell. The new method relies on the notion that many […]

Changing the Criteria for Diagnosing Alzheimer’s

 Diagnosing Alzheimer's  Comments Off on Changing the Criteria for Diagnosing Alzheimer’s
Jul 142010

Readers, Below is the first of a series of upcoming blogs reporting the news from ICAD, the International Conference on AD taking place this week in Hawaii. For the first time in 25 years, there is a proposal to change the criteria for Alzheimer’s disease, part of a new movement to diagnose and, eventually, treat the disease earlier. As readers will recall, Alzheimer’s is thought to begin years, perhaps even decades, before symptoms are noticeable. […]

National Institute on Aging and Alzheimer’s Association Lead Effort to Update Diagnostic Criteria for Alzheimer’s Disease

 Diagnosing Alzheimer's  Comments Off on National Institute on Aging and Alzheimer’s Association Lead Effort to Update Diagnostic Criteria for Alzheimer’s Disease
Jul 132010

Scientists at the Alzheimer’s Association International Conference on Alzheimer’s Disease 2010 (AAICAD 2010) today presented the first draft reports from three workgroups convened by the National Institute on Aging (NIA) and the Alzheimer’s Association to update the diagnostic criteria for Alzheimer’s disease for the first time in 25 years. The current criteria for the diagnosis of Alzheimer’s were established by a National Institute of Neurological Disorders and Stroke (NINDS)/Alzheimer’s Disease and Related Disorders Association (ADRDA) […]

Building on their previous discovery that people with Alzheimer’s have beta-amyloid deposits that appear as unusual cataracts in the lens of the eye, a team of researchers led by Dr. Lee Goldstein at Boston University School of Medicine, has discovered that beta-amyloid also accumulates in the eyes of people with Down syndrome. Down syndrome patients develop symptoms of Alzheimer’s Disease often by the age of 30 because they have an extra copy of a key […]

ApoE4 May Also Affect How AD Manifests Itself

 Diagnosing Alzheimer's  Comments Off on ApoE4 May Also Affect How AD Manifests Itself
Jun 022010

Readers, The Alzheimer’s Disease Neuroimaging Initiative (ADNI) continues to provide us with greater and more detailed information about AD. For quite some time, we have known that the ApoE4 genotype leads to an increased risk of developing sporadic AD. Patients with the ApoE4 gene (carriers) typically develop Alzheimer’s disease five to seven years earlier than those without the gene (non-carriers). One or more copies of the ApoE4 gene are present in 20 percent to 30 percent of the […]

Readers, Rarely a day goes by when we do not see several news items about the role of neuro-imaging in detecting, treating or monitoring the progression of Alzheimer’s disease. Here are a few comments to bear in mind as you consume the daily press. Magnetic Resonance Imaging (MRI) yields an image of brain structure and will reveal tumors, strokes and (importantly for Alzheimer’s disease) atrophy (or shrinkage) in particular parts of the brain that can […]
