Diagnosis of prions in patients should utilize novel strategy, conformation-dependent immunoassay

A technique for detecting prions in tissue, developed in recent years by UCSF scientists, is significantly more sensitive than the diagnostic procedures currently used to detect the lethal particles in samples of brain tissue from patients, according to a study performed by a UCSF team.

First comprehensive examination of strenuous physical activity and the risk of developing Parkinson's disease

In the first comprehensive examination of strenuous physical activity and the risk of developing Parkinson's disease, researchers from the Harvard School of Public Health (HSPH) have found that men who exercised regularly and vigorously early in their adult life had a lower risk for developing Parkinson's disease compared to men who did not.

Cannabis use may increase risk of stroke

Regular users of cannabis could be putting themselves at risk of stroke, while they are still young, indicates a case report, published in the Journal of Neurology Neurosurgery and Psychiatry.

Young blood revives aging muscles

Any older person can attest that aging muscles don't heal like young ones. But it turns out that's not the muscle's fault. A study in the Feb. 17 issue of Nature shows that it's old blood that keeps the muscles down.

Paradox suggests reasons why COX-2 inhibitors hurt and help

Laboratory studies at Johns Hopkins have revealed that certain products of the enzymes COX-1 and COX-2 can both protect and damage the brain. The findings, published in the February 2005 issue of the Journal of Neurochemistry, offer tantalizing clues to why drugs like Vioxx and Celebrex, which block COX-2, can ease arthritis but potentially harm the heart and brain.

Finding points towards the possibility of retrovirus involvement in ALS (amyotrophic lateral sclerosis)

A significant proportion of patients suffering from ALS (amyotrophic lateral sclerosis), also known as Lou Gehrig's disease or motor neuron disease, have a marker of retrovirus activity in their blood, reports the February 8 issue of the medical journal Neurology.

Link between heart disease and periodontal bacteria

Researchers report this week that older adults who have higher proportions of four periodontal-disease-causing bacteria inhabiting their mouths also tend to have thicker carotid arteries, a strong predictor of stroke and heart attack.

People with gum disease are more likely to suffer from atherosclerosis

A new study by researchers at Columbia University Medical Center provides the most direct evidence to date that preventing gum disease could significantly improve your chances of avoiding vascular problems.

Marijuana changes blood flow in the brain

People who smoked marijuana had changes in the blood flow in their brains even after a month of not smoking, according to a study published in the February 8 issue of Neurology, the scientific journal of the American Academy of Neurology.

People with autism may perform unusually well on some tests of visual processing

The researchers found that autistic people were less likely than others to have false memories about images they had seen earlier. The researchers had previously demonstrated this kind of effect with verbal material, but not with visual material.

Scientists have coaxed human embryonic stem cells to become spinal motor neurons

After years of trial and error, scientists have coaxed human embryonic stem cells to become spinal motor neurons, critical nervous system pathways that relay messages from the brain to the rest of the body.

Research into foot-eye coordination

By measuring how people respond when a stepping stone suddenly shifts its position mid-step, researchers at the Institute of Neurology in London have shown that a powerful visual process controls the stepping foot – a process similar to that used for manual reaching, in which the hand is rapidly and automatically driven by visual information.

High cholesterol, hypertension, diabetes and smoking may increase risk of dementia

High cholesterol, hypertension, diabetes and smoking have long been considered -- and aggressively treated -- as risk factors for cardiovascular disease.

Early seizures after surgery for epilepsy predict more seizures

Current understanding of seizures in the weeks just after epilepsy surgery is that they are likely to be temporary, probably due to swelling or minor trauma suffered by the brain during the operation.

African drug Ibogaine blocks alcohol cravings

A naturally occurring hallucinogen advocated by some clinicians as a potent anti-addiction drug has been rigorously studied for the first time, confirming its ability to block alcohol craving in rodents, and clarifying how it works in the brain.

Two minutes of magnetic stimulation can change your brain for an hour

A couple of minutes is all it takes to ‘knock out’ bits of your brain for an hour, according to a new study by a University College London (UCL) team.

Single gene mutation as the cause of around one in 25 cases of Parkinson’s disease worldwide

The studies suggest that the mutation, in a recently discovered gene called LRRK2, causes around 5% of inherited Parkinson’s cases and around 2% of isolated cases. Screening for the new mutation is likely to become a component of genetic testing for Parkinson’s disease in the near future.
