Potential diagnostic tool, treatment for Parkinson's disease -- ScienceDaily

In the new study, Wang's team obtained skin samples from 83 Parkinson's patients, five asymptomatic close relatives considered to be at heightened risk, 22 patients diagnosed with other movement disorders and 52 healthy control subjects. They extracted fibroblasts -- cells that are common in skin tissue -- from the samples, cultured them in petri dishes and subjected them to a stressful process that messes up mitochondria. This should result in their clearance, necessarily preceded by removal of Miro molecules tethering them to the grid. Yet the researchers found the Miro-removal defect in 78 of the 83 Parkinson's fibroblasts (94%) and in all 5 of the "high-risk" samples, but not in fibroblasts from the control group or other or from patients with other movement-disorders.

23andMe Is Sharing Genetic Data with Drug Giant - Scientific American

Only about 10,000 of the 1 million Americans with Parkinson’s disease have the disease because of LRRK2. So, GlaxoSmithKline has to test about 100 Parkinson’s patients to find just one potential candidate. However, 23andMe has already provided 250 Parkinson’s patients who have agreed to be re-contacted for GlaxoSmithKline’s clinical trials, which may help the pharmaceutical company develop the drug much faster, Forbes reported.

Brain Activity Alternates While Stepping - Neuroscience News

The researchers found that activity in the 20-30 Hz (beta) range alternated between the left and right STN when the opposite foot touched the ground and the other foot was to be raised. The introduction of a metronome synchronized to the cartoon steps improved participants’ accuracy and enhanced their STN beta activity accordingly.

Parkinson's May Begin in Gut and Spread to the Brain Via the Vagus Nerve - Neuroscience News

The research has presented strong evidence that Parkinson’s disease begins in the gastrointestinal tract and spreads via the vagus nerve to the brain. Many patients have also suffered from gastrointestinal symptoms before the Parkinson’s diagnosis is made. “Patients with Parkinson’s disease are often constipated many years before they receive the diagnosis, which may be an early marker of the link between neurologic and gastroenterologic pathology related to the vagus nerve ,” says Elisabeth Svensson.
