High calories associated with memory loss in elderly: Study

Overeating may lead to a higher risk of memory loss say researchers. A new study found that elderly who consumed more than 2,143 calories a day had more than double the risk of a type of memory loss called mild cognitive impairment (MCI) compared to those who ate fewer than 1,500 calories a day. The study appeared Sunday by the American Academy of Neurology on its website (aan.com).

Researchers discover a startling feature of early brain development

Researchers at the Salk Institute have discovered a startling feature of early brain development that helps to explain how complex neuron wiring patterns are programmed using just a handful of critical genes. The findings, published February 3 in Cell, may help scientists develop new therapies for neurological disorders, such as amyotrophic lateral sclerosis (ALS), and provide insight into certain cancers.

Overeating may increase risk of MCI among the elderly

New research suggests that consuming between 2,100 and 6,000 calories per day may double the risk of memory loss, or mild cognitive impairment (MCI), among people age 70 and older. The study was released today and will be presented at the American Academy of Neurology's 64th Annual Meeting in New Orleans April 21 to April 28, 2012. MCI is the stage between normal memory loss that comes with aging and early Alzheimer's disease.

Deep brain stimulation helps improve memory and cognitive skills in epilepsy patients

Researchers have found that deep brain stimulation by sending in electric shocks to a part of the brain that plays a key role in memory improved people's ability to learn. This could raise hope for patients of Alzheimer’s.

Tai chi could benefit Parkinson’s disease patients

A new study found that a six-month program of Tai Chi exercises helped people with various stages of Parkinson's disease improve stability, their ability to walk and reduced the frequency of falls.

Bupivacaine may effectively manage pain after total knee replacement

Researchers at the Rothman Institute at Jefferson have shown that local anesthesia delivered through a catheter in the joint, intraarticularly, may be more beneficial than traditional opioids such as morphine and Oxycontin for pain management following total knee replacement surgery.

Scientists identify single prion protein that causes neuronal death

Scientists from the Florida campus of The Scripps Research Institute have identified a single prion protein that causes neuronal death similar to that seen in "mad cow" disease, but is at least 10 times more lethal than larger prion species.

Gene therapy to promote remyelination in mouse model of MS

Our bodies are full of tiny superheroes-antibodies that fight foreign invaders, cells that regenerate, and structures that ensure our systems run smoothly. One such structure is myelin-a material that forms a protective, insulating cape around the axons of our nerve cells so that they can send signals quickly and efficiently. But myelin, and the specialized cells called oligodendrocytes that make it, become damaged in demyelinating diseases like multiple sclerosis (MS), leaving neurons without their myelin sheaths.

New device offers fresh hope for patients with Motor Neurone Disease

Patients suffering from a devastating disease are being given fresh hope through an innovative trial being led by the Sheffield Institute for Translational Neuroscience (SITraN) and Sheffield Teaching Hospitals.

Parkinson’s disease gene - parkin explored: Study

Researchers at the University at Buffalo have discovered how mutations in the parkin gene cause Parkinson's disease, which afflicts at least 500,000 Americans and for which there is no cure. The results are published in the current issue of Nature Communications.

Conventional method has minimal role in determination of PJI

In their search for new, better ways to diagnose periprosthetic joint infection, Rothman Institute at Jefferson researchers have discovered that measurement of C-reactive protein in the synovial fluid is extremely accurate, while measuring a patients- serum white blood cell count (WBC) and the percentage of neutrophils (PMN%), the conventional method for diagnosis, has a minimal role in the determination of PJI.

Thumb and little finger react faster than the middle finger

The fingers on the outside - i.e. the thumb and little finger - therefore react faster than the middle finger, which is exposed to the "cross fire" of two neighbours on each side. Through targeted learning, this speed handicap can be compensated. The working group led by PD Dr. Hubert Dinse (Neural Plasticity Lab at the Institute for Neuroral Computation) report in the current issue of PNAS.

Patients with degenerative spondylolisthesis do not benefit from epidural steroid injections

Researchers at the Rothman Institute at Jefferson examined data on patients being treated for lumbar stenosis and the degenerative spine condition spondylolisthesis and found that patients who received epidural steroid injections (ESI) had a higher rate of crossover to surgery and fared worse in physical health and bodily pain versus those who did not receive ESI, dispelling their pre-study hypothesis.

MRI techniques can measure changes in microstructural properties of white matter

Innovative magnetic resonance imaging (MRI) techniques that can measure changes in the microstructure of the white matter likely to affect brain function and the ability of different regions of the brain to communicate are presented in an article in the groundbreaking new neuroscience journal Brain Connectivity, a bimonthly peer-reviewed publication from Mary Ann Liebert, Inc.

Scientists discover how individual MST neurons function

When you are about to collide into something and manage to swerve away just in the nick of time, what exactly is happening in your brain? A new study from the Montreal Neurological Institute and Hospital - The Neuro, McGill University shows how the brain processes visual information to figure out when something is moving towards you or when you are about to head into a collision.

Study describes molecular pathway that controls rest and activity rhythms

The molecular pathway that carries time-of-day signals from the body's internal clock to ultimately guide daily behavior is like a black box, says Amita Sehgal, PhD, the John Herr Musser Professor of Neuroscience and Co-Director, Comprehensive Neuroscience Center, at the Perelman School of Medicine, University of Pennsylvania.

Study examines dimensional structure linked with DSM antisocial personality disorder criteria

With no lab tests to guide the clinician, psychiatric diagnostics is challenging and controversial. Antisocial personality disorder is defined as "a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood," according to the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) of the American Psychiatric Association.
