Hippocampal atrophy seen with early cognitive decline in Parkinson's disease, Penn study shows Atrophy in the hippocampus, the region of the brain known for memory formation and storage, is evident in Parkinson's disease (PD) patients with cognitive impairment, including early decline known as mild cognitive impairment (MCI), according to a study by researchers in the Perelman School of Medicine at the University of Pennsylvania. The study is published in the December issue of the Archives...

Study to see if walking and/or memory training may prevent memory problems in people with Parkinson's disease Researchers from the University of Maryland School of Medicine and the Baltimore VA Medical Center have launched a study of exercise and computerized memory training to see if those activities may help people with Parkinson's disease prevent memory changes. The type of memory that will be examined is known as "executive function;" it allows people to take in information and use it...

Amyotrophic lateral sclerosis (ALS; also known as Lou Gehrig's disease) is an incurable adult neurodegenerative disorder that progresses to paralysis and death. Genetic mutations are the cause of disease in 5% of patients with ALS. Of immense interest, Hongxia Zhou, Xu-Gang Xia, and colleagues, at Thomas Jefferson University, Philadelphia, now show that progressive neuron degeneration can be halted in a rat model of familial ALS linked to mutations in the gene that carries the instructions...

Cortisol may be the Swiss Army knife of hormones in the human body-just when scientists think they understand what it does, another function pops up. While many of these functions are understood for adults, much less is known about how cortisol operates in babies and toddlers, especially when it comes to an important phenomenon called the cortisol awakening response, or CAR. For the first time, psychology researchers from the University of Georgia Franklin College of Arts and Sciences have...

A diametric shift in the levels of two proteins involved in folding, moving and cutting other proteins enables accumulation of the destructive brain plaque found in Alzheimer's disease, researchers report. VPS35 is a protein that folds others into specific positions to unleash their functions. When levels are reduced as they are in aging, it unleashes the normally dormant BACE1, a protein responsible for beta amyloid plaque production, Georgia Health Sciences University researchers report...

Study highlights importance of diagnosing 'overlap syndrome' in sufferers of muscle weakness disease (ALS) and early-onset dementia (FTD) In order to better counsel patients, it is key for clinicians of different disciplines to be aware of, and diagnose, the 'overlap syndrome' between two medical disorders - ALS and FTD - since it significantly affects patient survival. In her new study´, Catherine Lomen-Hoerth, from the University of California San Francisco in the US, also...

(Ivanhoe Newswire) — According to a recent study, two proteins conspire to promote a lethal neurological disease. Amyotrophic lateral sclerosis, ALS, also known as Lou Gehrig´s disease, is a neurodegenerative disorder that results in progressing loss of motor function and ultimately death. More than 90 percent of ALS cases have no known genetic cause or family history. However, in some patients, spinal cord cells contain unusual accumulations of a protein called TDP-43....

(Ivanhoe Newswire)– Don´t forget to watch your weight! Previous studies have shown that middle-aged people who are overweight are more likely to develop Alzheimer's disease later in life. Yet a new study, published in the November 22, 2011 print issue of Neurology®, the medical journal of the American Academy of Neurology, found that people in the earliest stages of Alzheimer's disease are more likely to have a lower body mass index. The study used advanced brain imaging...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
