Parkinson's disease symptoms mainly relate to movement because the condition results in a loss of nerve cells in the part of the brain responsible for producing a chemical called dopamine. Dopamine acts as a messenger between the parts of the brain and nervous system that help control and coordinate body movements. One area of the body that can be affected is the feet. If stiffness in the feet occurs often, it could be a sign of something more serious.

Parkinson’s disease is a condition that causes the brain to become progressively more damaged over time, said the NHS. You could be at risk of the neurodegenerative condition if you find that you're not blinking as often as you're used to.

A novel finding will enable experimental studies to determine whether and how pathogens play a role in triggering Parkinson's disease.

Belgian scientists have identified a novel risk gene for Parkinson's disease that can help find effective therapy against a disease that affects over 10 million people worldwide.

Living near major roads or highways is linked to higher incidence of dementia, Parkinson's disease, Alzheimer's disease and multiple sclerosis (MS), suggests new research published this week in the journal Environmental Health.

Scientists have discovered that a non-invasive technique which could one day be used to treat Parkinson's disease, can successfully target a highly specific group of brain cells which play a key role in development of the condition.

More than a quarter of people with Parkinson’s disease were initially misdiagnosed, new research has found.

A drug used to treat enlarged prostates may be a powerful medicine against Parkinson's disease, according to an international team of scientists.

Cell replacement may play an increasing role in alleviating the symptoms such as movement problems and memory loss of Parkinson's disease (PD), researchers said.

The brain chemical missing in Parkinson’s disease may have a hand in its own death. Dopamine, the neurotransmitter that helps keep body movements fluid, can kick off a toxic chain reaction that ultimately kills the nerve cells that make it, a new study suggested.

Computer games could help lessen the effects of Parkinson’s disease, according to research by British neuroscientists.

Hepatitis B and C viruses may both be associated with a significantly increased risk of Parkinson's disease, a new study found.

Researchers from the University of Bergen in Norway have found that the secret to Parkinson's disease may be in cells' mitochondria.

Researchers may have discovered a method of detecting changes in the eye which could identify Parkinson's disease before its symptoms develop.

A traumatic brain injury with loss of consciousness may increase the risk of developing Parkinson's disease, new research suggests.
