New modeling of brain’s circuitry may bring better understanding of Parkinson’s disease

Researchers from the School of Science at Indiana University-Purdue University Indianapolis have developed a mathematical model of the brain’s neural circuitry that may provide a better understanding of how and why information is not transmitted correctly in the brains of Parkinson’s disease patients. This knowledge may eventually help scientists and clinicians correct these misfires.… New modeling of brain’s circuitry may bring better understanding of Parkinson’s disease   



Freezing Parkinson’s in Its Tracks

Parkinson’s disease, a disorder which affects movement and cognition, affects over a million Americans, including actor Michael J. Fox, who first brought it to the attention of many TV-watching Americans. It’s characterized by a gradual loss of neurons that produce dopamine. Mutations in the gene known as DJ-1 lead to accelerated loss of dopaminergic… Freezing Parkinson’s in Its Tracks   



Medtronic’s Brain Device Improves Early-Stage Parkinson’s

Patients with early Parkinson’s disease who respond to drug therapy gain improvement in their symptoms and quality of life when they receive deep-brain stimulation from an implanted medical device, a study showed.

Brain stimulation is now reserved for advanced Parkinson’s patients with severe complications and inconsistent response to drug treatment. The findings suggest patients… Medtronic’s Brain Device Improves Early-Stage Parkinson’s   



Genetic mutation increases risk of Parkinson’s disease from pesticides

A team of researchers has brought new clarity to the picture of how gene-environmental interactions can kill nerve cells that make dopamine. Dopamine is the neurotransmitter that sends messages to the part of the brain that controls movement and coordination. Their discoveries, described in a paper published online in Cell today, include identification… Genetic mutation increases risk of Parkinson’s disease from pesticides   



Novel compound keeps Parkinson’s symptoms at bay in mice

Scientists report that they have developed a novel compound that appears to protect mice against developing movement problems associated with Parkinson’s disease (PD). The research, which could one day in the future translate into a therapy that could halt the progression of PD and thereby prevent the symptoms of the disease, appears in ACS’… Novel compound keeps Parkinson’s symptoms at bay in mice   



Mere expectation of treatment can improve brain activity in Parkinson’s patients

Learning-related brain activity in Parkinson’s patients improves as much in response to a placebo treatment as to real medication, according to a new study by researchers at the University of Colorado Boulder and Columbia University.

Past research has shown that while Parkinson’s disease is a neurological reality, the brain systems involved may also be… Mere expectation of treatment can improve brain activity in Parkinson’s patients
