People who develop a type of irregular heartbeat common in old age called atrial fibrillation may also be more likely to develop problems with memory and thinking, according to new research published in the June 5, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Research has shown that healthy behaviors are associated with a lower risk of Alzheimer's disease and dementia, but less is known about the potential link between positive lifestyle choices and milder memory complaints, especially those that occur earlier in life and could be the first indicators of later problems.
Blood offers promise as a way to detect Alzheimer’s disease at its earliest onset, Mayo Clinic researchers say. They envision a test that would detect distinct metabolic signatures in blood plasma that are synonymous with the disease -- years before patients begin showing cognitive decline. Their study was recently published online in the journal PLOS ONE.
An Alzheimer’s disease protein controls the speed at which materials move through brain cells, and defects could lead to deadly pileups of the kind seen in neurodegenerative disease, a new publication finds.
Teams of highly respected Alzheimer’s researchers failed to replicate what appeared to be breakthrough results for the treatment of this brain disease when they were published last year in the journal Science.
A new study looking at sleep-disordered breathing (SDB) and markers for Alzheimer’s disease (AD) risk in cerebrospinal fluid (CSF) and neuroimaging adds to the growing body of research linking the two.
People who have skin cancer may be less likely to develop Alzheimer's disease, according to new research published in the May 15, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. The link does not apply to melanoma, a less common but more aggressive type of skin cancer.
Using long-term patient data, scientists at Washington University School of Medicine in St. Louis have found that many of the biomarkers for Alzheimer’s identified in recent years can help accurately predict the start of full-blown disease years in advance.
A drug developed by scientists at the Salk Institute for Biological Studies, known as J147, reverses memory deficits and slows Alzheimer's disease in aged mice following short-term treatment. The findings, published May 14 in the journal Alzheimer's Research and Therapy, may pave the way to a new treatment for Alzheimer's disease in humans.
Mutations in genes that regulate cellular metabolism found in families with ataxia, dementia and reproductive failure.
Virginia Tech Carilion Research Institute scientists discover that cholinesterase inhibitors allow signals to enter the brain with less background noise. And the drugs work in the sensory cortices, not the more sophisticated processing regions.
Scientists’ picture of how a gene strongly linked to Alzheimer’s disease harms the brain may have to be revised, researchers at Washington University School of Medicine in St. Louis have found.
A University of Iowa study shows that older people can put off the aging of their minds by playing a simple game that primes their processing speed skills. The research showed participants' cognitive skills improved in a range of functions, from improving peripheral vision to problem solving. Results published in the journal PLOS One.
Elderly patients who receive anesthesia are no more likely to develop long-term dementia or Alzheimer’s disease than other seniors, according to new Mayo Clinic research. The study analyzed thousands of patients using the Rochester Epidemiology Project -- which allows researchers access to medical records of nearly all residents of Olmsted County, Minn. -- and found that receiving general anesthesia for procedures after age 45 is not a risk factor for developing dementia. The findings were published Wednesday, May 1, online in Mayo Clinic Proceedings.
A UAB study suggests that the Mediterranean diet, which urges consuming foods that contain omega-3 fatty acids found in fish, chicken and salad dressing, and avoiding saturated fats, meat and dairy foods, may be linked to preserving memory and thinking abilities.
Research Identifies Potential Therapeutic Targets for Late Onset Alzheimer’s Disease (LOAD) By Revealing a Network of Genes Involved in the Inflammatory Response.
Alzheimer's researchers know the disease is caused by toxic beta amyloid and tau lesions, yet, the recent failure of emerging therapies targeting these lesions suggest that successful treatments will require diagnosis of disease at its earliest stages. Now, by using computer-aided drug discovery, researchers are in the process of developing an imaging chemical that attaches predominantly to tau-bearing lesions in living brain, opening the door for earlier diagnosis – and better treatments for tau-involved conditions like Alzheimer’s, frontal temporal dementia and traumatic brain injuries.
Neuroscientists at The University of Texas Health Science Center at Houston (UTHealth) have taken a major step in their efforts to help people with memory loss tied to brain disorders such as Alzheimer’s disease.
Studying rats’ ability to navigate familiar territory, Johns Hopkins scientists found that the hippocampus uses remembered spatial information to imagine routes the rats then follow. Their discovery has implications for memory loss due to Alzheimer's disease and aging.
Researchers at Mayo Clinic in Florida participated in a nationwide study that found minor differences between genes that contribute to late-onset Alzheimer’s disease in African-Americans and in Caucasians.
