Exercise for the brain may slow dementia

People who engage in activities that exercise the brain, such as reading, writing, and playing card games, may delay the rapid memory decline that occurs if they later develop dementia, according to a study published in the August 4, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.

Elevated cholesterol levels in midlife raises risk of late-life dementia

Elevated cholesterol levels in midlife - even levels considered only borderline elevated - significantly increase the risk of Alzheimer's disease and vascular dementia later in life, according to a new study by researchers at Kaiser Permanente's Division of Research and the University of Kuopio in Finland. The study appears in the journal Dementia & Geriatric Cognitive Disorders.

Long-term brain damage after bypass surgery - more evidence puts blame on heart disease

Brain scientists and cardiac surgeons at Johns Hopkins have evidence from 227 heart bypass surgery patients that long-term memory losses and cognitive problems they experience are due to the underlying coronary artery disease itself and not ill after-effects from having used a heart-lung machine.

Neural correlates of impaired cognitive-behavioral flexibility in anorexia nervosa

Anorexic patients drastically reduce food intake and are often not capable of changing their behavior. This can lead to life-threatening weight loss. Using MRI technology, scientists at Heidelberg University Hospital have discovered for the first time processes in brain metabolism that explain this disturbed eating behavior.

Hypertension may lead to ‘silent’ strokes

"Silent" strokes, which are strokes that don't result in any noticeable symptoms but cause brain damage, are common in people over 60, and especially in those with high blood pressure, according to a study published in the July 28, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.

Maternal exposure to nanoparticles related to neurological dysfunction in the mouse

Maternal exposure to nanoparticles of titanium dioxide (TiO2) affects the expression of genes related to the central nervous system in developing mice. Researchers writing in BioMed Central's open access journal Particle and Fibre Toxicology found that mice whose mothers were injected with the nanoparticles while pregnant showed alteration in gene expression related to neurological dysfunction.

Acute stress improves working memory

Day after day of chronic stress will wear a person down physically and mentally. But new research suggests that the acute stress produced by a brief run-in with a stressful scenario acts on a key brain region controlling emotion and cognition, temporarily improving learning and memory.

Trial to begin on alternative treatment for depression

The University of New South Wales (UNSW) and The Black Dog Institute are seeking participants for a trial of a new, non-invasive form of brain stimulation therapy for depression, known as Direct Current Stimulation (DCS).

New clues about the roots of neurological disease

Switching off a key DNA repair system in the developing nervous system is linked to smaller brain size as well as problems in brain structures vital to movement, memory and emotion, according to new research led by St. Jude Children's Research Hospital scientists.

Improving patients' attention after a stroke could help them recover their motor skills

Scientists in New Zealand say after a stroke improving patients' attention could help them to recover their motor skills.

Potassium citrate wards off kidney stones in epilepsy patients on ketogenic diet

Children on the high-fat ketogenic diet to control epileptic seizures can prevent the excruciatingly painful kidney stones that the diet can sometimes cause if they take a daily supplement of potassium citrate the day they start the diet, according to research from Johns Hopkins Children's Center.

National Institutes of Health develops research plan on Fragile X syndrome and associated disorders

The National Institutes of Health has developed a research plan to advance the understanding of fragile X syndrome and its associated conditions, fragile X-associated tremor/ataxia syndrome and fragile X-associated primary ovarian insufficiency. Fragile X syndrome causes intellectual and developmental disabilities and results from a mutation in a gene on the X chromosome.

Potential new treatment for Alzheimer’s

Indeed, these carriers tend to develop the disease later than others, but when that happens, it progresses more rapidly and does not respond to medication. Therefore, the bottom line is that carriers of the mutated gene have a greater risk than others for disease progression.

Preliminary findings in Phase IIA trial point to natural compound NIC5-15's potential in Alzheimer's disease

Researchers at Mount Sinai School of Medicine have found that a compound called NIC5-15, might be a safe and effective treatment to stabilize cognitive performance in patients with mild to moderate Alzheimer's disease.

Past exercise helps stroke patients recover faster

A person who has exercised regularly prior to the onset of a stroke appears to recover more quickly, say researchers from Mayo Clinic in Florida, who led a national study.

Discovery of novel receptor in the brain, potential target for Alzheimer's

Barrow Neurological Institute researchers have identified a novel receptor in the brain that is extremely sensitive to beta-amyloid peptide (AB) and may play a key role in early stages of Alzheimer's disease.

Genetic source of muscular dystrophy blocked

Researchers at the University of Rochester Medical Center have found a way to block the genetic flaw at the heart of a common form of muscular dystrophy. The results of the study, which were published today in the journal Science, could pave the way for new therapies that essentially reverse the symptoms of the disease.

Scientists create new way to study brain function

Scientists at Duke University and the University of North Carolina have devised a chemical technique that promises to allow neuroscientists to discover the function of any population of neurons in an animal brain, and provide clues to treating and preventing brain disease.

Research sheds light on social brain development

The capacity to figure out what others are thinking and what they mean is an ability unique to people that's central to our lives. A new study on the neural mechanisms that govern these abilities sheds light on the relation between how people and groups interact, on the one hand, and how the brain develops and functions, on the other.

Discovery of new mechanism controlling neuronal migration

The molecular machinery that helps brain cells migrate to their correct place in the developing brain has been identified by scientists at St. Jude Children's Research Hospital.
