Insulin resistance occurs in the brains of people with Alzheimer's

Insulin resistance in the brain precedes and contributes to cognitive decline above and beyond other known causes of Alzheimer's disease, according to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania. Insulin is an important hormone in many bodily functions, including the health of brain cells.

New method for measurement of aggregated beta-amyloid in AD

An international team of researchers have developed a new method for measurement of aggregated beta-amyloid - a protein complex believed to cause major nerve cell damage and dysfunction in Alzheimer's disease. The new method might facilitate diagnosis and detection as well as development of drugs directed against aggregated beta-amyloid.

International Alzheimer's experts unite for global effort

The world’s leading Alzheimer’s disease researchers and clinicians will gather in Melbourne this week to agree on standardisation and validation of important diagnostic and prognostic parameters used in Alzheimer’s research centres around the globe.

Obesity in later life linked to decreased mental faculties

The study found said out of 250 test subjects involving people over 59 years old, people between 60 and 70 who had the highest BMIs also had the lowest cognitive function. There was also a connection between visceral fat -- otherwise known as the belly fat around the torso - and poor mental abilities. The study, which was published in the British journal Age and Aging, measured the subjects fat-related measures including BMI, waist circumference and the amount of visceral - which could be close to organs - and subcutaneous -under the skin - fat using a abdominal CT scan. Cognitive ability was determined by a test called a Mini-Mental State Examination.

Paul Allen pledges $300 million to better understand the brain’s inner workings

Microsoft co-founder and billionaire Paul Allen is donating $300 million to his Allen Institute for Brain Science to fund new projects to map and observe the human brain and, in Allen’s words, “to one day understand the essence of what makes us human.” That brings the total amount Allen has invested in the Institute to half a billion.

Research roundup: Unequal 'culture of quality' in hospitals; Peer-support for stressed doctors

Comparison Of Hospital Performance In Trauma Vs Emergency And Elective General Surgery –This study compared outcomes of trauma patients and patients having either elective or emergency surgery in the same hospital. Researchers thought that "hospital performance reflected institutional culture, and, thus, would be similar across all services."

Hospitalized older adults may have increased risk of cognitive decline

A new study published in the March 21 issue of Neurology suggests that older adults who are hospitalized may have an increased risk of subsequent cognitive decline.

Allen Institute for Brain Science receives $300M gift to expand scientific programs

The Allen Institute for Brain Science announced today that, given its achievements to date, Paul G. Allen has committed an additional $300 million to the Institute to significantly expand its scientific programs.

Computer program could help dementia patients manage their disease

Researchers at Weill Cornell Medical College have developed a computer program that has tracked the manner in which different forms of dementia spread within a human brain. They say their mathematic model can be used to predict where and approximately when an individual patient's brain will suffer from the spread, neuron to neuron, of "prion-like" toxic proteins -- a process they say underlies all forms of dementia.

Alpha-5 GABA type A receptors linked to anesthesia-related memory loss

A drug targeting one specific receptor may provide the first effective approach to treatment for the common problem of memory loss after surgery and anesthesia, according to an experimental study in the April issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society.

Alzheimer's may spread through connected neurons

Alzheimer's disease and other forms of dementia may spread within nerve networks in the brain by moving directly between connected neurons, instead of in other ways proposed by scientists, such as by propagating in all directions, according to researchers who report the finding in the March 22 edition of the journal Neuron.

Hospitalized older people may have increased risk of memory problems

A new study suggests that older people may have an increased risk of problems with memory and thinking abilities after being in the hospital, according to research published in the March 21, 2012, online issue of Neurology, the medical journal of the American Academy of Neurology.

Elevated Aβ peptide levels may lead to onset of AD

The effects of the bacterial endotoxin lipopolysaccharide (LPS) has been found to elevate amyloid beta (Aβ) peptide levels in the brain, leading to short-term deficits in learning.

DIAN-TTU to receive $4.2M Alzheimer's Association research grant

The Alzheimer's Association announced today the awarding of its largest ever research grant – nearly $4.2 million dollars over four years – to the Dominantly Inherited Alzheimer's Network–Therapeutic Trials Unit (DIAN-TTU), based at Washington University School of Medicine in St. Louis, to enable the program to move forward more quickly with innovative drug and biomarker trials in people with genetically-based, young-onset Alzheimer's disease.

Alzheimer's Association awards $4.2M grant to DIAN-Therapeutic Trials Unit

Washington University School of Medicine in St. Louis has received nearly $4.2 million from the Alzheimer's Association to accelerate the launch of the first clinical trials to prevent the symptoms of Alzheimer's disease.

FKBP52 may prevent hyperphosphorylation of pathogenic Tau protein

New research in humans published today reveals that the so-called FKBP52 protein may prevent the Tau protein from turning pathogenic. This may prove significant for the development of new Alzheimer's drugs and for detecting the disease before the onset of clinical symptoms.

Two new studies strongly support link between insulin resistance and Alzheimer's

An emerging body of research suggests that Alzheimer's disease may be linked to insulin resistance, constituting a third type of diabetes. This model is based on several observations including an increased risk of developing Alzheimer's disease for diabetic patients, and reduced insulin levels in the brain tissue of Alzheimer's disease patients. Though intriguing, the existing evidence does not reveal if defective insulin signaling is causative of Alzheimer's or how insulin resistance impacts cognitive function.

Scientists investigate molecular mechanism of memory encoding in neurons

University of Alberta led research may have discovered how memories are encoded in our brains. Scientists understand memory to exist as strengthened synaptic connections among neurons. However components of synaptic membranes are relatively short-lived and frequently re-cycled while memories can last a lifetime.
