Reasoning and behavioral control dependent on different regions of frontal lobes

The frontal lobes are the largest part of the human brain, and thought to be the part that expanded most during human evolution. Damage to the frontal lobes-which are located just behind and above the eyes-can result in profound impairments in higher-level reasoning and decision making. To find out more about what different parts of the frontal lobes do, neuroscientists at the California Institute of Technology (Caltech) recently teamed up with researchers at the world's largest registry of brain-lesion patients.

Working memory capacity in patients with Parkinson's can be improved with sleep

People with Parkinson's disease performed markedly better on a test of working memory after a night's sleep, and sleep disorders can interfere with that benefit, researchers have shown.

Neurally-interfaced hand prosthesis re-establishes communication between nervous systems

Amputation disrupts not only the peripheral nervous system but also central structures of the brain. While the brain is able to adapt and compensate for injury in certain conditions, in amputees the traumatic event prevents adaptive cortical changes. A group of scientists reports adaptive plastic changes in an amputee's brain following implantation of multielectrode arrays inside peripheral nerves.

People with metabolic abnormalities may experience rapid decline in their cognitive skills

People who are obese and also have high blood pressure and other risk factors called metabolic abnormalities may experience a faster decline in their cognitive skills over time than others, according to a study published in the August 21, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology.

Study shows significant benefits of temporal training on cognitive function in the elderly

Research has found that declines in temporal information processing (TIP), the rate at which auditory information is processed, underlies the progressive loss of function across multiple cognitive systems in the elderly, including new learning, memory, perception, attention, thinking, motor control, problem solving, and concept formation. In a new study, scientists have found that elderly subjects who underwent temporal training improved not only the rate at which they processed auditory information, but also in other cognitive areas.

PD risk factors for potential clinical screening identified

A meta-analysis has identified 19 risk factors that significantly impact a person’s risk for Parkinson’s disease and could be of potential value for clinical screening, say the authors.

Standardized sign-out improves neurology handoffs

The implementation of a structured sign-out process significantly improves satisfaction that handoffs between neurology staff have been completed fully and accurately, show study results published in Neurology.

Three-step risk-screening method devised for Parkinson’s disease

Researchers have proposed a three-step screening battery to identify people at risk for developing Parkinson’s disease, using a combination of age, family history, hyposmia, and substantia nigra enlargement.

Parkinson’s disease with dementia falls into two pathologic subgroups

Patients with Parkinson’s disease who also have dementia fall into two main pathologic categories, characterized by neocortical synucleinopathy in isolation and neocortical synucleinopathy with amyloid beta deposition.

FDA approves InSightec's ExAblate Neuro system clinical trial for tremor dominant Parkinson's Disease

InSightec Ltd, the global leader in MR guided Focused Ultrasound (MRgFUS), announced that it has received approval from the US Food and Drug Administration to begin a Phase I clinical trial evaluating the use of its ExAblate Neuro system for the treatment of patients with tremor dominant Parkinson's Disease.

NYU Langone's Hospital for Joint Diseases achieves Magnet recognition by ANCC

NYU Langone Medical Center's Hospital for Joint Diseases (HJD) has achieved Magnet recognition by the American Nurses Credentialing Center (ANCC), the international accrediting body that recognizes healthcare organizations focused on nursing excellence.

Damage to the ventromedial prefrontal cortex increases credulity

Everyone knows the adage: "If something sounds too good to be true, then it probably is." Why, then, do some people fall for scams and why are older folks especially prone to being duped? An answer, it seems, is because a specific area of the brain has deteriorated or is damaged, according to researchers at the University of Iowa.

Research examines racial and ethnic differences in strokes

Blacks who survived a stroke caused by bleeding in the brain had higher blood pressure than whites a year later, according to a study published today in the journal Stroke. The finding might help explain why blacks have a greater risk of suffering a second stroke than whites.

Febrile seizures increase hippocampal injury risk

Children with febrile status epilepticus are at risk for hippocampal injury and show abnormalities in the development of this brain area, show findings from a prospective multicenter study.

People with no dementia symptoms and high protein levels more likely to avoid the disease

People who are free of dementia and have high levels of a protein that indicates the presence of inflammation have relatives who are more likely to avoid the disease as well, according to a new study published in the August 15, 2012, online issue of Neurology, the medical journal of the American Academy of Neurology.

Cedars-Sinai's ICT-107 doubles median survival of patients with malignant brain tumor

An experimental immune-based therapy more than doubled median survival of patients diagnosed with the most aggressive malignant brain tumor, Cedars-Sinai Medical Center researchers reported in Cancer Immunology, Immunotherapy, published online Aug. 3.

Combination of exercise and S-nitrosoglutathione improves recovery from stroke

In a study published in the current issue of Restorative Neurology and Neuroscience scientists report that a therapy combining exercise with the neurovascular protective agent S-nitrosoglutathione (GSNO) improved recovery from stroke in a rat model. GSNO is a compound found naturally in the body and it has no known side effects or toxicity.
