Parkinson's Disease

Parkinson's disease is a brain disorder. It occurs when certain nerve cells (neurons) in a part of the brain called the substantia nigra die or become impaired. When approximately 80 percent of neurons are damaged, the symptoms of Parkinson's disease appear. Parkinson's disease affects 1 in 100 people over the age of 60, with the average age of onset being 60 years. The risk of developing Parkinson's disease increases with age. In the United States, it is estimated that 60,000 new cases of Parkinson's disease are diagnosed each year, with 1.5 million Americans currently living with the disease.

What is Parkinson's Disease?

Parkinson's disease is a degenerative disease of the brain. It affects parts of the brain that are associated with normal movement and balance.

Novel assay for identifying individuals with synucleinopathies using serum samples

Synucleinopathies are a group of neurodegenerative diseases caused by the abnormal accumulation α-synuclein, a protein normally found in the brain and neurons. Incorrect folding of α-synuclein leads to formation of 'seeds', which attract more α-synuclein proteins to form larger clumps.

Research could help develop better treatments for swallowing disorders

Sensory cells in the vagus nerve can detect and locate food in the esophagus. Their signals help transport the food onward to the stomach. Signal failure leads to swallowing disorders, say a team led by Carmen Birchmeier at the Max Delbrück Center.
