Researchers report an advance in the development of a blood test that could help detect Alzheimer’s disease in people who are showing signs of dementia. The new approach could be less invasive and less costly than current brain imaging and spinal fluid tests. The blood test detects the abnormal accumulation of a form of tau… Continue reading Progress Reported toward Earlier Diagnosis of Alzheimer’s

Experts Discover Five New Risk Genes for Alzheimer’s
Researchers report that they have discovered five new risk genes for Alzheimer’s disease, while confirming others that are already known. The international team of researchers, who analyzed results from more than 94,000 people, also reported for the first time that mutations in genes specific to the protein tau, a hallmark of Alzheimer’s disease, may play… Continue reading Experts Discover Five New Risk Genes for Alzheimer’s
How Memory Changes as We Get Older
It’s known that when it comes to memory proficiency, there are differences between younger and older adults. Now, though, researchers report that data from brain imaging can zero in to show the underlying causes for such memory deficits. The findings appeared in the journal Neuron. “At the fundamental level, we still understand very little about… Continue reading How Memory Changes as We Get Older
Canola Oil Linked to Alzheimer’s
Canola oil is thought to be healthy, yet new research shows that its consumption is linked with worsened memory, worsened learning ability and weight gain – all of which model Alzheimer’s disease. However, in an earlier study by the same investigators, extra-virgin olive oil was shown to have the opposite effect. The study was published… Continue reading Canola Oil Linked to Alzheimer’s
Why Glucose Level in Brain Signals Alzheimer’s
One of the earliest signs of Alzheimer’s disease is a decline in glucose levels in the brain. It appears in the early stages of mild cognitive impairment – before symptoms of memory problems begin to surface. Whether it is a cause or consequence of neurological dysfunction has been unclear, but new research at the Lewis… Continue reading Why Glucose Level in Brain Signals Alzheimer’s
The Start of Alzheimer’s: A New Understanding
Australian researchers have shed new light on the nerve cell processes that lead to Alzheimer’s Disease . The discovery overturns previously held ideas of how the disease develops. It may alo pave the way to new treatment options that could halt or slow its progression. The study was published in the journal Science. Studying human… Continue reading The Start of Alzheimer’s: A New Understanding
Found: Important Clue to Development of Alzheimer’s
Researchers have discovered a gene signature in healthy brains that echoes the pattern in which Alzheimer’s disease spreads through the brain. The findings, published in the journal Science Advances, could help uncover the molecular origins of this devastating disease, and may be used to develop preventative treatments for at-risk individuals to be taken well before… Continue reading Found: Important Clue to Development of Alzheimer’s
A New Cause of Alzheimer’s?
Blocking a key brain–cell receptor may eventually lead to neutralizing some consequences of Alzheimer’s, according to a new study from Temple University. The brain cells are used by “oxygen free radicals” that are linked to “oxidative stress.” That “stress” occurs when the production of the free radicals is greater than the body’s ability to detoxify… Continue reading A New Cause of Alzheimer’s?
