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

Researchers have found a way to transform glial cells into dopamine-producing cells, representing a major advancement in the quest for a Parkinson's cure.

Parkinson's risk may be higher with hepatitis virus infection

Thu, 30 Mar 2017 00:00:00 PDT

Researchers have found that people infected with hepatitis B or C may be at significantly higher risk of developing Parkinson's disease.

Parkinson's: 2.5 hours of weekly exercise benefits mobility, quality of life

Fri, 24 Mar 2017 08:00:00 PDT

Researchers have found that patients with Parkinson's disease who exercise for at least 2.5 hours weekly have slower declines in mobility and life quality.

FDA approves drug to treat Parkinson's disease

Wed, 22 Mar 2017 06:00:00 PDT

The U.S. Food and Drug Administration has approved Xadago (safinamide) tablets as an add-on treatment for patients with Parkinson's disease who are currently taking levodopa/carbidopa and...

New research suggests bowel cancer medication could help combat early-onset Parkinson's disease

Thu, 16 Mar 2017 00:00:00 PDT

People with certain forms of early-onset Parkinson's disease could potentially benefit from taking a medication used to treat certain forms of cancer, according to new research by University of...

'Red hair' gene variant may underlie association between melanoma and Parkinson's disease

Mon, 06 Mar 2017 00:00:00 PDT

A gene variant that produces red hair and fair skin in humans and in mice, which increases the risk of the dangerous skin cancer melanoma, may also contribute to the known association between...

Parkinson's: 'Genetic switch' may play key role in preserving brain cells

Fri, 17 Feb 2017 07:00:00 PDT

Study finds a genetic switch that controls PINK1 and PARKIN genes, defects in which cause mitchondrial dysfunction seen in some forms of Parkinson's.

Mitochondrial lipids as potential targets in early onset Parkinson's disease

Tue, 14 Feb 2017 06:00:00 PDT

A team of researchers led by Patrik Verstreken (VIB-KU Leuven) have identified an underlying mechanism in early onset Parkinson's.

Alzheimer's may be linked to defective brain cells spreading disease

Tue, 14 Feb 2017 00:00:00 PDT

Rutgers scientists say neurodegenerative diseases like Alzheimer's and Parkinson's may be linked to defective brain cells disposing toxic proteins that make neighboring cells sick.

Blood test may help differentiate Parkinson's from similar diseases

Fri, 10 Feb 2017 00:00:00 PDT

A simple blood test may be as accurate as a spinal fluid test when trying to determine whether symptoms are caused by Parkinson's disease or another atypical parkinsonism disorder, according to a...
