Researchers have developed a new technology that helps Parkinson's patients overcome the tendency to speak too quietly by playing a recording of ambient sound, which resembles the noisy chatter of a restaurant full of patrons.

An enzyme that naturally occurs in the brain helps destroy the mutated protein that is the most common cause of inherited Parkinson's disease, researchers at UT Southwestern Medical Center have found.

The classic symptoms of Parkinson's disease involve tremor, stiffness and slow movements. Over the last decade, neurologists have been paying greater attention to non-motor symptoms, such as digestive and sleep problems, loss of sense of smell and depression.

Transdermal drug delivery has gained a solid market position in a few specialty markets, owing to the unique advantages it provides in selected therapeutic applications. Now these advantages are beginning to inure to a class of conditions that are particularly well-suited to the major benefits of transdermal drug administration.

The Nintendo Wii may help treat symptoms of Parkinson's disease, including depression, a Medical College of Georgia researcher says.
Parkinson’s disease is a degenerative disease that impairs motor skills. Dr. Herz theorized that the popular computer game console, which simulates various sports and activities, could improve coordination, reflexes and other movement-related skills, but he found additional benefits as well.

Researchers at the Tokyo Metropolitan Institute for Neuroscience, Tokyo, Japan established the mechanism by which gangliosides may help treat Parkinson's disease. These data are presented in the May 2009 issue of The American Journal of Pathology.

A new study conducted at Mayo Clinic reports that one in six patients receiving therapeutic doses of certain drugs for Parkinson's disease develops new-onset, potentially destructive behaviors, notably compulsive gambling or hypersexuality.

Teams of scientists from Australia and the United States have used yeast and mammalian cells to discover a connection between genetic and environmental causes of Parkinson's disease.

Will scientists one day be able to slow the aging of the brain and prevent diseases such as Alzheimer's and Parkinson's? Absolutely – once the genetic coding associated with neuronal degeneration has been unraveled.

Neurologists have observed for decades that Lewy bodies, clumps of aggregated proteins inside cells, appear in the brains of patients with Parkinson's disease and other neurodegenerative diseases.

Many individuals with Parkinson's disease are able to recall losing their sense of smell well before the onset of more commonly recognized symptoms such as tremors, impaired dexterity, speech problems, memory loss and decreased cognitive ability.

A new study by Narendra et al. suggests that Parkin, the product of the Parkinson's disease-related gene Park2, prompts neuronal survival by clearing the cell of its damaged mitochondria.
