Ohio State trial suggest PD can be treated with ultrasound waves

Saturday December 24, 2016

Krishna used no scalpel. There was no drilling, either. Instead, Krishna's tool was a computer mouse that helped him deliver more than 1,000 high-intensity, focused ultrasound waves into Nickelson's brain.

Parkinson's disease: Blocking brain enzyme corrects motor symptoms in mice

Friday December 16, 2016

New drug research shows promising results in mice bred to develop the motor symptoms of Parkinson's disease. A team in Finland finds that blocking an enzyme called prolyl oligopeptidase clears the mice's brains of an accumulated protein that is a hallmark of Parkinson's disease, halts further brain damage, and corrects movement impairment.

Opinion: 21st Century Cures Act is a clear victory for patients and their families

Friday December 16, 2016

The 21st Century Cures Act passed with overwhelming bipartisan support in both the House of Representatives (by a vote of 392-26) and the Senate (94–5), and now has been signed into law by the president of the United States. This represents a substantial step forward for everyone who wants to see safer and more effective medicines developed faster and more efficiently.

Parkinson's Disease Questions Answered

Monday December 12, 2016

Last month, former US Attorney General Janet Reno passed away from complications of Parkinson disease (PD). With the condition in the news as a result, clinicians are no doubt seeing an increase in patient inquiries about the debilitating neurodegenerative disorder. Medscape recently spoke with Rachel M. Dolhun, MD, vice president of medical communications at The Michael J. Fox Foundation for Parkinson's Research, about the latest in understanding and managing PD.

Early intervention may be possible for Parkinson's disease

Friday December 09, 2016

One of the largest post-mortem brain studies in the world has confirmed that a protein (LRRK2) associated with the development of Parkinson's disease is increased in the pre-symptom stages, leading researchers to believe they may be able to treat the disease sooner.

Parkinson's disease: Stand Corrected

Thursday December 08, 2016

In a new study published online in the journal Neurology, a research team led by neurologists at Harvard Medical School and Beth Israel Deaconess Medical Center and neuropsychologists at Boston University has shown that when patients with Parkinson’s disease experience a drop in blood pressure upon standing up—a condition known as orthostatic hypotension (OH)—they exhibit significant cognitive deficits. These deficits reverse when they lie down and their blood pressure returns to normal.

Imaging technique measures toxicity of Alzheimer's, Parkinson's proteins

Wednesday November 23, 2016

A new imaging technique has been created that makes it possible to study why proteins associated with Alzheimer's and Parkinson's diseases may go from harmless to toxic. The technique uses a technology called multi-dimensional super-resolution imaging that makes it possible to observe changes in the surfaces of individual protein molecules as they clump together. The tool may allow researchers to pinpoint how proteins misfold and eventually become toxic to nerve cells in the brain, which could aid in the development of treatments for these devastating diseases.
