Moderate physical activity performed in midlife or later appears to be associated with a reduced risk of mild cognitive impairment, whereas a six-month high-intensity aerobic exercise program may improve cognitive function in individuals who already have the condition, according to two reports in the January issue of Archives of Neurology, one of the JAMA/Archives journals.
Stroke patients admitted to the hospital on the weekend appear more likely to receive the clot-dissolving medication tissue plasminogen activator than patients admitted during the week, according to a report in the January issue of Archives of Neurology, one of the JAMA/Archives journals. However, stroke death rates appear similar among weekend and weekday admissions.
A combined positron emission tomography-computed tomography (PET-CT) scan of the whole body appears to detect cancer in individuals with related neurologic complications more accurately than some other commonly used tests, according to a report posted online today that will appear in the March print issue of Archives of Neurology, one of the JAMA/Archives journals.
New research has shown that reducing the dosage of dopamine agonist (DA) drugs, a mainstay treatment for Parkinson's disease (PD), sometimes causes acute withdrawal symptoms similar to those reported by cocaine addicts -- including anxiety, panic attacks, depression, sweating, nausea, generalized pain, fatigue, dizziness and drug cravings. These symptoms can be severe, and are not alleviated by other PD medications.
Blocking the function of an enzyme in the brain with a specific kind of vitamin E can prevent nerve cells from dying after a stroke, new research suggests.
Forgot where you put your car keys? Having trouble recalling your colleague’s name? If so, this may be a symptom of subjective cognitive impairment (SCI), the earliest sign of cognitive decline marked by situations such as when a person recognizes they can’t remember a name like they used to or where they recently placed important objects the way they used to. Studies have shown that SCI is experienced by between one-quarter and one-half of the population over the age of 65. A new study, published in the January 11, 2010, issue of the journal Alzheimer’s & Dementia, finds that healthy older adults reporting SCI are 4.5 times more likely to progress to the more advanced memory-loss stages of mild cognitive impairment (MCI) or dementia than those free of SCI.
MDA awards $2.5 million grant to ALS TDI, of Cambridge, MA., in unique, collaborate pact to fund therapeutic treatments for deadly neurological disease. ALS TDI is on the fast track in developing treatments for ALS patients, using previous MDA funding of $18 million.
Using laboratory mice that had been bred to have brain changes similar to Alzheimer’s disease, scientists were able to reduce two characteristic features of the disease by modifying the mice’s immune systems with a special peptide (MOG45D) related to the myelin sheath that insulates nerve cells and nerve fibers. As a result, anti-inflammatory cells were recruited from the blood into the brain, dampening the local inflammatory response.
A new type of brain scan, called diffusion tensor imaging (DTI), appears to be better at detecting whether a person with memory loss might have brain changes of Alzheimer’s disease, according to a new study published in the January 6, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology.
The less you use your brain’s frontal lobes, the more you see yourself through rose-colored glasses, a University of Texas at Austin researcher says.
Neuroscientists at MIT have developed a powerful new class of tools to reversibly shut down brain activity using different colors of light. When targeted to specific neurons, these tools could potentially lead to new treatments for the abnormal brain activity associated with disorders such as chronic pain, epilepsy, brain injury, and Parkinson’s disease.
A canine chromosome 7 locus that confers a high risk of compulsive disorder susceptibility has been identified through a collaboration between the Behavior Service at the Cummings School of Veterinary Medicine, the Program in Medical Genetics at the University of Massachusetts Medical School and the Broad Institute at the Massachusetts Institute of Technology. The findings are published in the January 2010 edition of Nature Molecular Psychiatry.
Inheritance of an extra copy of the gene- ß -amyloid precursor protein, APP, in individuals with Down syndrome leads to the inevitable development of early onset Alzheimer’s disease, known to be linked to the deposition of Amyloid ß peptide or Aß in the brain. However, a new study published online in PNAS identifies ßCTF, a small protein found in APP, as a novel factor for the development of Alzheimer’s disease related endosome abnormalities, which have also been tied previously to the loss of brain cells in Alzheimer’s disease.
A new guideline issued by the American Academy of Neurology finds that transcutaneous electric nerve stimulation (TENS), a widely used pain therapy involving a portable device, is not recommended to treat chronic low-back painpain that has persisted for three months or longerbecause research shows it is not effective. The guideline is published in the December 30, 2009, online issue of Neurology®.

By combining a research technique that dates back 136 years with modern molecular genetics, a Johns Hopkins neuroscientist has been able to see how a mammal’s brain shrewdly revisits and reuses the same molecular cues to control the complex design of its circuits.
Several similar small molecules appear capable of protecting cells from alpha-synuclein toxicity, a hallmark of Parkinson’s disease. There is currently no cure for the disease, and current Parkinson’s therapies only address disease symptoms, not the disease’s cellular cause.
The early stages of Alzheimer’s disease are thought to occur at the synapse, since synapse loss is associated with memory dysfunction. Evidence suggests that amyloid beta (Aβ) plays an important role in early synaptic failure, but little has been understood about Aβ’s effect on the plasticity of dendritic spines.
Like a spotlight that illuminates an otherwise dark scene, attention brings to mind specific details of our environment while shutting others out. A new study by researchers at the Salk Institute for Biological Studies shows that the superior colliculus, a brain structure that primarily had been known for its role in the control of eye and head movements, is crucial for moving the mind’s spotlight.
UCLA scientists have identified a molecular switch that prevents Huntington's disease from developing in mice. Published in the Dec. 24 edition of the journal Neuron, the discovery suggests a new approach to treating the genetic disorder, which ultimately leads to death in as little as 10 years.
People who have Alzheimer’s disease may be less likely to develop cancer, and people who have cancer may be less likely to develop Alzheimer’s disease, according to a new study published in the December 23, 2009, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A group of Norwegian and American researchers have shown that common variations in genes associated with microcephaly – a neuro-developmental disorder in which brain size is dramatically reduced – may explain differences in brain size in healthy individuals as well as in patients with neurological and psychiatric disorders.
A simple bedside exam performed by a skilled physician can be superior to a high-tech CT scan. Researchers found that bedside exams did a better job than CT scans in predicting which patients would need to return to the operating room to treat complications.
Over three decades, a world-recognized medical team at UC San Diego Medical Center has spurred the evolution of a complex surgery to destroy dangerous clusters of arteries and veins in the brain. Integrating innovative approaches in radiology, anesthesia, and surgery, the team has perfected a method to systematically starve these abnormal brain lesions, artery by artery, vein by vein.

Although there were promising results in a phase 2 trial, patients with mild Alzheimer disease who received the drug tarenflurbil as part of a phase 3 trial did not have better outcomes on measures of cognitive decline or loss of activities of daily living compared to patients who received placebo.
The study, led by researchers at the Johns Hopkins Bloomberg School of Public Health, is the first of its kind to demonstrate that social service programs can have the added benefits of improving the cognitive abilities of older adults. Using functional magnetic resonance imaging (fMRI), the researchers found that seniors participating in a youth mentoring program made gains in key brain regions that support cognitive abilities important to planning and organizing one’s daily life.
For the first time, researchers at Washington University in St. Louis have shown that brain plaques in apparently healthy individuals are associated with increased risk of diagnosis with Alzheimer's disease years later.
Intensive medical therapy, including aggressive control of blood pressure and cholesterol levels, for patients with asymptomatic plaque buildup in their carotid arteries (which supply blood to the brain) appears to be associated with reduced rates of cardiovascular events and reduced risk of microemboli (microscopic-sized blood clots) in the brain arteries, according to a report posted online today that will appear in the February 2010 print issue of Archives of Neurology, one of the JAMA/Archives journals.
Early Alzheimer’s disease detected by a compound that binds to brain plaques appears likely to progress into symptomatic Alzheimer’s disease with dementia, according to a report in the December issue of Archives of Neurology, one of the JAMA/Archives journals.

Estrogen has a dual role in brain as a hormone and, indirectly, as a neurotransmitter, according to PNAS study which suggests a strategy for replacing hormone therapy.
More than half of HIV patients experience memory problems and other cognitive impairments as they age, and doctors know little about the underlying causes. New research from Washington University School of Medicine in St. Louis suggests HIV-related cognitive deficits share a common link with Alzheimer's-related dementia: low levels of the protein amyloid beta in the spinal fluid.
Neurology researchers have shown that feeding amino acids to brain-injured mice restores their cognitive abilities and may set the stage for the first effective treatment for cognitive impairments suffered by people with traumatic brain injuries. Every 23 seconds, a man, woman or child in the U.S. suffers a traumatic brain injury.
People who drink may want to know that coffee won’t sober them up, according to new laboratory research. Instead, a cup of coffee may make it harder for people to realize they’re drunk.
Neuroscientists at the Mayo Clinic campus in Jacksonville, Fla., have demonstrated how brain waves can be used to type alphanumerical characters on a computer screen. By merely focusing on the “q” in a matrix of letters, for example, that “q” appears on the monitor.
A new study published this week in the Journal of Neurosurgery: Pediatrics finds that operative plans for removing Juvenile Pilocytic Astrocytoma, or JPA, tumors in the thalamus of the brain can be augmented with Diffusion Tensor Imaging, or DTI. The sensitivity of DTI imaging allows for the visualization of nerve fiber bundles in the brain. This information can maximize the potential of completely removing the tumor while avoiding damage to the fiber bundles that are directly related to motor functions of the patient.
A new study to determine whether the use of antithrombotic medications among stroke survivors increased over a seven-year period found that in each of the years, approximately 20 percent of survivors were not taking these medications — a figure that did not decrease during the time period. The study also found that individuals who were younger, female or Hispanic were less likely to be taking antithrombotic agents.
Our ability to learn new information and adapt to changes in our daily environment, as well as to retain lifelong memories, appears to lie in the minute junctions where nerve cells communicate, according to a new study by NYU Langone Medicine Center researchers. The study is published online this week in the journal Nature.
