Medical advancements in the fight against Alzheimer's
One in three people in the United States of America know someone who has been afflicted with Alzheimer's disease. These people are the ones who can explain exactly how devastating the disease can be to not only the person that is afflicted, but also those who love the patient and care for them. Since the disease can cause so much pain, many have joined in the fight against Alzheimer's, making contributions to research organizations and struggling to learn more about the disease that can make a person forget who they are. At the forefront of these contributions come many new studies showing promise for the future with regards to Alzheimer's. In this article, we'll discuss some of the advancements that have been made recently with regards to Alzheimer's disease.
One recent discovery in the field of medicine has shown doctors a little more about how the disease actually attacks the body. Since the disease was discovered, we've known that a build-up of plaque is present in the brain of a person who is afflicted with Alzheimer's. This is the only sure-fire way of diagnosing if a patient has the disease, and it can only be checked for when the individual is deceased via an autopsy.
Doctors in Quebec have recently learned a fundamental reason for which the plaque may be developing in Alzheimer's patients, and this explanation can lead towards more accurate ways of fighting the disease. The researchers discovered that there is a type of cell present in the brain that are known as microglia. They discovered that these cells were, in fact, the body's natural way of defeating the plaque that Alzheimer's is known for. However, in those afflicted with the disease, the microglia appears to be unable to fight off the plaques. For that reason, the plaque can multiply and grow, leading to the eventual complete loss of the patient's mental processes.
Upon this discovery, the researchers realized that curing Alzheimer's may rely on finding ways for the microglia to successfully fight off the plaque. For a solution, they turned to a different type of microglia found in a different part of the body - inside bone marrow. Employing the use of mice to test their hypothesis, the scientists were pleased to find that the microglia from the bone marrow successfully fought off the plaque caused by Alzheimer's.
This shows a remarkable amount of promise for the future of Alzheimer's research; eventually, the scientists hope to be able to take stem cells from a patient and then use those cells to aid the microglia already in the brain, forming a fighting-force to eliminate the plaque. The researchers also stressed that the use of anti-inflammatory drugs in order to treat Alzheimer's should be avoided, as it may interfere with the microglia trying to do their job.
While eliminating the plaque associated with Alzheimer's isn't a complete solution for the disease, if successful in human trials, it will allow patients to live with the disease for a longer period of time without as much cognitive loss.

Famous 1848 Case Of A Man Who Survived A Terrible Brain Injury Has Modern Parallel
Poor Phineas Gage. In 1848, the supervisor for the Rutland and Burlington Railroad in Vermont was using a 13-pound, 3-foot-7-inch rod to pack blasting powder into a rock when he triggered an explosion that drove the rod through his left cheek and out of the top of his head. As reported at the time, the rod was later found, "smeared with blood and brains... |
New Clues On How ApoE4 Affects Alzheimer's Risk
Common variants of the ApoE gene are strongly associated with the risk of developing late-onset Alzheimer's disease, but the gene's role in the disease has been unclear. Now, researchers funded by the National Institutes of Health have found that in mice, having the most risky variant of ApoE damages the blood vessels that feed the brain... |
Obama's Grand Plan To Cure Alzheimer's
Obama's healthcare goals have been controversial at best, and although anti-smoking campaigns and other public health and safety awareness drives have been successful, it's always somewhat dubious when government starts creating grand plans and lofty goals... |
Dementia Sufferers More Likely To Die At Home Than In Nursing Homes
A new study from the Regenstrief Institute and Indiana University has found that, at time of death, individuals with dementia are more likely to be living at home than in a nursing home. This contradicts the commonly held view that most individuals with dementia in the United States eventually move to nursing homes and die there... |
Could A Compound Found In Red Wine And Red Grapes Change The Course Of Alzheimer's Disease?
A national, phase II clinical trial examining the effects of resveratrol on individuals with mild to moderate dementia due to Alzheimer's disease has begun as more than two dozen academic institutions recruit volunteers in the coming months. R. Scott Turner, M.D., Ph.D., director of Georgetown University Medical Center's Memory Disorders Program, is the lead investigator for the national study... |
Memory Improved In Amnestic Mild Cognitive Impairment By Reducing Excess Brain Activity
Research published by Cell Press in the journal Neuron, describes a potential new therapeutic approach for improving memory and modifying disease progression in patients with amnestic mild cognitive impairment. The study finds that excess brain activity may be doing more harm than good in some conditions that cause mild cognitive decline and memory impairment... |
Middle Aged And Elderly With Depression Have Higher Risk Of Dementia
A report in the May issue of Archives of General Psychiatry draws a link between people in mid-life and late-life, suffering from depression and the possibility of them developing dementia. More than five million people in the US alone suffer from Alzheimer's disease, and the health care costs run at a staggering $172 Billion. Deborah E. Barnes, Ph.D., M.P.H... |
Memantine Improves Some Alzheimer's Symptoms But Has No Effect On Agitation
A drug prescribed for Alzheimer's disease does not ease clinically significant agitation in patients, according to a new study conducted by researchers from the U.K., U.S. and Norway. This is the first randomized controlled trial designed to assess the effectiveness of the drug (generic name memantine) for significant agitation in Alzheimer's patients... |
Discovery Of Potential Trigger For Alzheimer's Disease
A highly toxic beta-amyloid - a protein that exists in the brains of Alzheimer's disease victims - has been found to greatly increase the toxicity of other more common and less toxic beta-amyloids, serving as a possible "trigger" for the advent and development of Alzheimer's, researchers at the University of Virginia and German biotech company Probiodrug have discovered... |
Too Early To Promote Smell Test For Alzheimer's
A study published online in The Laryngoscope reveals that current studies do not support the use of olfactory identification tests (smell tests) for predicting Alzheimer's dementia. Alzheimer's is a progressive disease that causes loss of brain function and is the most common cause of dementia. The disease is expected to double every 20 years through the year 2040... |
Helping Patients With Dementia Live Well
Care Services Minister Paul Burstow unveiled a range of new design prototypes at the Design Council that can help people with dementia to live well, which included a fragrance-release system designed to stimulate appetite, specially-trained 'guide dogs for the mind' and an intelligent wristband that supports people with dementia to stay active safely... |
Strong Support Uncovered For Once-Marginalized Theory On Parkinson's Disease
University of California, San Diego scientists have used powerful computational tools and laboratory tests to discover new support for a once-marginalized theory about the underlying cause of Parkinson's disease. The new results conflict with an older theory that insoluble intracellular fibrils called amyloids cause Parkinson's disease and other neurodegenerative diseases... |
'Use It Or Lose It' - Protecting Your Brain
The findings of a new study suggest that the protective effects of an active cognitive lifestyle arise through multiple biological pathways. For some time researchers have been aware of a link between what we do with our brains and the long term risk for dementia. In general, those who are more mentally active or maintain an active cognitive lifestyle throughout their lives are at lower risk... |
