The results from a new study by neurological researchers from the Rush Alzheimer’s Disease Center at Rush University Medical Center suggest that people who were emotionally neglected as children may have a higher risk of stroke in later adulthood.
Scientists at Washington University School of Medicine in St. Louis have taken one of the first detailed looks into how Alzheimer’s disease disrupts coordination among several of the brain’s networks.
Surgery causes a lasting increase in Alzheimer’s pathology in AD mice, via transient activation of brain inflammation. There was a clear and persistent decrement in learning and memory caused by surgery as compared with inhalational anesthesia – but only in the context of a brain made vulnerable by human Alzheimer-associated transgenes.
This week, a strategic roadmap to help to the nation’s health care system cope with the impending public health crisis caused Alzheimer’s disease and related dementia will be published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association. The plan aims to link the latest scientific findings with clinical care and bring together patients, families, scientists, pharmaceutical companies, regulatory agencies, and advocacy organizations behind a common set of prioritized goals. The consensus document is the outcome of a June meeting of leading Alzheimer's researchers, advocates and clinicians, who gathered as part of the Marian S. Ware Alzheimer Program at the University of Pennsylvania.
New research shows that professional football players may be at a higher risk of death from diseases that damage the cells in the brain, such as Alzheimer’s disease and ALS (also known as Lou Gehrig’s disease), compared to the general U.S. population. The study is published in the September 5, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.

UCLA researchers found that older adults who regularly used a brain fitness program played on a computer demonstrated significantly improved memory and language skills.
The greatest risk factor for Alzheimer’s disease (AD) is advancing age. By age 85, the likelihood of developing the dreaded neurological disorder is roughly 50 percent. But researchers at the University of California, San Diego School of Medicine say AD hits hardest among the “younger elderly” – people in their 60s and 70s – who show faster rates of brain tissue loss and cognitive decline than AD patients 80 years and older.
The physical benefits of the Olympic sports are pretty obvious: strength, endurance and agility, to name a few. But did you know they also can help the brain? Mayo Clinic research shows that any exercise that gets the heart pumping may reduce the risk of dementia and mild cognitive impairment -- and slow those conditions if they start. Aerobic exercise also can boost your mood.
An international team of scientists led by researchers at Mount Sinai School Medicine have discovered that a drug that had previously yielded conflicting results in clinical trials for Alzheimer’s disease effectively stopped the progression of memory deterioration and brain pathology in mouse models of early stage Alzheimer’s disease.
Jianhua Xing, a Virginia Tech assistant professor of biology, and his colleagues recommend further study of how rope-like polymers called microtubules function. They computational comparations of two models of microtubules, a component of cell cytoskeletons.
A study, performed in mice and utilizing post-mortem samples of brains from patients with Alzheimer’s disease, found that a single event of a moderate-to-severe traumatic brain injury (TBI) can disrupt proteins that regulate an enzyme associated with Alzheimer’s. The paper, published in The Journal of Neuroscience, identifies the complex mechanisms that result in a rapid and robust post-injury elevation of the enzyme in the brain.

Metabolic syndrome, a term used to describe a combination of risk factors that often lead to heart disease and type 2 diabetes, seems to be linked to lower blood flow to the brain, according to research by the University of Wisconsin School of Medicine and Public Health.
Researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center found that people with a form of mild cognitive impairment (MCI), a risk factor for developing Alzheimer’s disease, have twice the risk of dying compared with cognitively normal people. Those with dementia have three times the risk. The findings are being presented at the Alzheimer’s Association International Conference in Vancouver this week.
Activity lingers longer in certain areas of the brain in those with Alzheimer’s than it does in healthy people, Mayo Clinic researchers who created a map of the brain found. The results suggest varying brain activity may reduce the risk of Alzheimer’s disease. The study, “Non-stationarity in the “Resting Brain’s” Modular Architecture,” was presented at the Alzheimer’s Association International Conference and recently published in the journal PLoS One.
Dangers of seniors wandering off and getting lost can often end in tragedy and appear to be more common as evident by the steady announcements of Silver Alerts, similar to Amber Alerts for missing children, across the country. The problem is so widespread that understanding why seniors wander could help keep them safe and avoid tragic consequences, say geriatric experts from the Harris County Hospital District.
In light of the Alzheimer’s Association International Conference taking place in Vancouver next July, CIHR wants to give reporters all the background information they need about the state of Alzheimer’s research.
Modern anesthesia is extremely safe. But as risks to heart, lungs and other organs have waned, another problem has emerged in the elderly: post-operative cognitive dysfunction. Mentally, some patients “just aren’t the same” for months or longer after surgery. Other factors play a role, but a small number of patients deteriorate mentally due to anesthesia per se. Those with Alzheimer’s disease suffer exacerbations, and those without the diagnosis may have it unmasked by anesthesia, suggesting some relationship.
Preventing diabetes or delaying its onset has been thought to stave off cognitive decline -- a connection strongly supported by the results of a 9-year study led by researchers at the University of California, San Francisco (UCSF) and the San Francisco VA Medical Center.
The Mount Sinai Medical Center is the first institution in New York State to use in the clinical setting a newly approved imaging technique to detect Alzheimer’s disease (AD) in people who are cognitively impaired. Until now, physicians have been limited in their ability to diagnose AD, guided almost exclusively by a patient’s mental and behavioral symptoms and family history.
In a new study published in PLoS Biology this week researchers address an urgent need to find ways to promote beneficial amyloid fiber assembly or to reverse its pathogenic assembly, at will.
Research published in the Genetics Society of America’s June 2012 issue of the journal GENETICS suggests a gene related to Alzheimer’s disease is also involved in the insulin pathway, which may explain the link between Alzheimer’s and diabetes.

A study on a handful of people with suspected mild Alzheimer’s disease (AD) suggests that a device that sends continuous electrical impulses to specific “memory” regions of the brain appears to increase neuronal activity. Results of the study using deep brain stimulation, a therapy already used in some patients with Parkinson’s disease and depression, may offer hope for at least some with AD, an intractable disease with no cure.
A new study suggests that eating foods that contain omega-3 fatty acids, such as fish, chicken, salad dressing and nuts, may be associated with lower blood levels of a protein related to Alzheimer’s disease and memory problems. The research is published in the May 2, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.
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.
Scientists now have a better understanding of how precise memories are formed thanks to research led by Prof. Jean-Claude Lacaille of the University of Montreal’s Department of Physiology. “In terms of human applications, these findings could help us to better understand memory impairments in neurodegenerative disorders like Alzheimer's disease,” Lacaille said. The study looks at the cells in our brains, or neurons, and how they work together as a group to form memories.
