Regular physical activity may decrease risk of AD even in very old adults

Daily physical activity may reduce the risk of Alzheimer's disease and cognitive decline, even in people over the age of 80, according to a new study by neurological researchers from Rush University Medical Center that will be published in the online issue of Neurology, the medical journal of the American Academy of Neurology on April 18.

Brain size and IQ secret may lie in genes: Study

The study, conducted by a team of more than 200 scientists from 100 institutions worldwide, measured the size of the brain and its memory centers in thousands of MRI images from 21,151 healthy people while simultaneously screening their DNA. According to the researchers, a variant in a gene called HMGA2 affected the brain size, as well as a person's intelligence.

Abbott reports positive results from LCIG Phase 3 trial for advanced Parkinson's disease

Abbott announced today the results from a Phase 3 trial evaluating the company's investigational compound for advanced Parkinson's disease, levodopa-carbidopa intestinal gel (LCIG).

Levodopa-carbidopa intestinal gel better than standard oral form to treat advanced Parkinson's disease

A levodopa-carbidopa intestinal gel (LCIG) works better than standard oral levodopa-carbidopa in reducing "off" time in patients with advanced Parkinson's disease.

Research on molecular mechanisms underlying Alzheimer's disease

Alzheimer's disease has been described as the "looming epidemic on the horizon." More than 5 million Americans currently suffer from this neurodegenerative disease that robs patients of their memories, and this number is projected to triple by the middle of the century.

More insight into tangled proteins in Alzheimer's disease

In Alzheimer's disease, brain neurons become clogged with tangled proteins. Scientists suspect these tangles arise partly due to malfunctions in a little-known regulatory system within cells. Now, researchers have dramatically increased what they know about this particular regulatory system in mice. Such information will help scientists better understand Alzheimer's and other diseases in humans and could eventually provide new targets for therapies.

PDAD patients have much denser accumulations of striatal plaques in the brain

Dementia is a frequent complication of Parkinson's disease (PD), but it is clinically impossible to distinguish PD dementia (PDD), which develops from the progression of the Lewy body pathology that underlies PD, from PD with coexistent Alzheimer's disease.

Nurr1 gene plays a fundamental role in neuron survival

Researchers at the Institute of Neurosciences at Universitat Aut-noma de Barcelona (INc-UAB) identified the fundamental role played by the Nurr1 gene in neuron survival associated with synaptic activity. The discovery, published in the Journal of Biological Chemistry, allows scientists to study a new target that could help to understand the relationship between alterations in neural connections, which are known to cause early cognitive deficit, and the neurodegeneration characteristic of Alzheimer's disease.

Paper points out decision-making capacity of patients with dementia

Luis Carlos álvaro, a clinical neurologist at the Hospital of Basurto (Bilbao) and lecturer at the University of the Basque Country (UPV/EHU), has had an article published on the capacity of patients with dementia to make decisions. It is entitled Competencia: conceptos generales y aplicación en la demencia (Competence: general concepts and application in dementia), and has been published in the journal Neurología.

Abnormal protein accumulation in the brain may lead to onset, severity of Parkinson's

Injection of a small amount of clumped protein triggers a cascade of events leading to a Parkinson's-like disease in mice, according to an article published online this week in the Journal of Experimental Medicine.

Metformin associated with reduced risk of Parkinson's in patients with diabetes

A major 12-year study based on a Taiwanese population cohort has demonstrated that not only does diabetes increase the risk of developing Parkinson's disease more than 2-fold, the use of sulfonylureas, commonly used as treatment for diabetes, increases the risk further by about 57%. This study also found that by including metformin in the therapy, no increased risk in developing Parkinson's disease was recorded.

ONO-4641 reduces number of lesions in people with MS

An investigational oral drug called ONO-4641 reduced the number of lesions in people with multiple sclerosis (MS), according to the results of a phase two clinical trial to be presented as Emerging Science at the American Academy of Neurology's 64th Annual Meeting in New Orleans April 21 to April 28, 2012.

Study: 1 in 26 may develop epilepsy at some point in life

A landmark study from the Institute of Medicine (IOM) reports that your chance of developing epilepsy at some point in your life is one in 26. Onset is highest in children and older adults. But epilepsy knows no boundaries—it can strike at any age and across all socio-economic levels and ethnicities. There is no known cure and one-third of people with epilepsy have treatment-resistant or refractory epilepsy.

Genes linked to major brain functions and disorders

An international team of researchers have found the genes that increase or reduce the risk of certain mental illnesses and Alzheimer's disease. They claim that some genes that may explain individual differences in brain size and intelligence as well. The team of more than 200 scientists at 100 institutions said this was the largest-ever brain study to date.

HHS report finds nursing homes not prepared for natural disasters

The authors suggest that the federal government mandate better planning. At the same time, many nursing home officials are arguing that as the economy improves, states should increase their funding of Medicaid.

New drug to detect beta-amyloid plaques may help diagnose AD earlier

Use of a new drug to detect the beta-amyloid plaques in the brain that are hallmark signs of Alzheimer's disease may help doctors diagnose the disease earlier, according to research that will be presented as part of the Emerging Science program (formerly known as Late-Breaking Science) at the American Academy of Neurology's 64th Annual Meeting in New Orleans April 21 to April 28, 2012.

Florbetaben PET scan reliably identifies beta-Amyloid in the brain

Piramal Imaging SA, a newly formed subsidiary of Piramal Healthcare Limited, announced positive first results from a Phase III study that showed that PET imaging with florbetaben reliably detects beta-Amyloid in the brain during life with great accuracy and thus shows value as a potential tool to aid in the diagnosis and assessment of Alzheimer's disease.

Two research studies on genetic components of Alzheimer's

Two research studies, co-led by UC Davis neurologist Charles DeCarli and conducted by an international team that included more than 80 scientists at 71 institutions in eight countries, has advanced understanding of the genetic components of Alzheimer's disease and of brain development. Both studies appear in the April 15 edition of the journal Nature Genetics.

New genes may explain individual differences in brain size and intelligence

In the world's largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain's resistance to a variety of mental illnesses and Alzheimer's disease.
