Parkinson's Disease News From Medical News Today



Parkinson's disease is a condition in which an area of the brain becomes progressively damaged over several years. The main signs of Parkinson's disease are tremor, slow movement, stiff and inflexible muscles. There is currently no cure for Parkinson’s

Parkinson's: Stem cells restore nerve function in monkeys

Thu, 31 Aug 2017 00:00:00 PDT

Scientists have created dopaminergic neurons from human stem cells and implanted them in monkeys with Parkinson's, restoring their nerve function.



Why a diabetes drug could help in Parkinson's disease

Thu, 31 Aug 2017 00:00:00 PDT

Using cell cultures, German researchers show how the drug may regulate the energy balance in damaged body cells.



Telemedicine as effective as in-person care for Parkinson's disease

Fri, 18 Aug 2017 00:00:00 PDT

New findings from a nationwide program that links neurologists with patients with Parkinson's disease in their homes via video conferencing shows that telemedicine can successfully deliver quality...



Early life physical activity may prevent cognitive decline

Tue, 15 Aug 2017 00:00:00 PDT

A new study in rodents shows how physical exercise in early life creates a cognitive reserve that improves cognition and neuronal activity in later years.



Life-extending protein could treat Alzheimer's and Parkinson's

Tue, 08 Aug 2017 09:00:00 PDT

A new study successfully used the protein hormone klotho to improve cognition in mice with Parkinson's and Alzheimer's-like brain toxicity.



Diabetes shot boosts motor function for patients with Parkinson's

Fri, 04 Aug 2017 08:00:00 PDT

A placebo trial shows that the diabetes drug exenatide improved motor symptoms of Parkinson's disease and may have disease-altering potential.



Waterlogged brain region helps scientists gauge damage caused by Parkinson's disease

Mon, 31 Jul 2017 00:00:00 PDT

Scientists at the University of Florida have discovered a new method of observing the brain changes caused by Parkinson's disease, which destroys neurons important for movement.
