What is Parkinson's Disease?

Parkinson's disease belongs to a group of conditions called motor system disorders, which are the result of the loss of dopamine-producing brain cells. The four primary symptoms of Parkinson's disease are tremor, or trembling...

Treadmill Training Improves Movement in Parkinson's Disease Patients

Treadmill training can be used to help people with Parkinson's disease achieve better walking movements, say researchers. In a systematic review of the evidence, researchers concluded treadmill training could be used to improve specific...

Researchers Identify Genetic Risk Factor for Parkinson's Disease

According to researchers, gene variant influences vitamin B6 metabolism, and in addition, this genome-wide expression and association study confirms that vitamin B6 status and metabolism significantly influence both Parkinson's disease risk and therapy. Scientists...

Dopamine Replacement Therapy and Dysfunction in Parkinson's Disease

People with Parkinson's disease are more likely to display abnormal social behavior and make poor decisions in ambiguous circumstances if they are pathological gamblers, according to research.

Parkinson's Disease Study Provides Insight Into Behavioral Addictions

New research unravels the brain mechanisms that underlie the ability of a standard drug treatment for Parkinson's disease to elicit compulsive behaviors in some patients with the disease.

Molecules Found to Protect Cells from Toxicity in Parkinson's Disease

Several structurally similar small molecules appear capable of protecting cells from alpha-synuclein toxicity in multiple models of Parkinson's disease, according to Whitehead Institute researchers. Misfolded copies of the alpha-synuclein protein in brain cells are...

Synergistic Interaction Enhances Parkinson's Disease Development

Scientists have identified a synergistic interaction that disrupts normal intracellular transport mechanisms and leads to the accumulation of neuron-damaging clumps of protein associated with Parkinson's disease, a neurodegenerative disorder that is characterized by a...

Brain Protein Plays a Role in Parkinson's Disease and Drug Addiction

Researchers have identified a protein that appears not only to be central to the process that causes Parkinson's disease but could also play a role in the high from methamphetamine and other addictive drugs....

Irregular Arm Swing Could Be an Early Sign of Parkinson's Disease

According to research by neurologists, irregular arm swings while walking could be an early sign of Parkinson's disease. Parkinson's disease is an age-related disorder involving loss of certain types of brain cells and marked...

Hormone Produced in Stomach Could Boost Resistance to Parkinson's

Researchers have discovered that a hormone produced in the stomach called ghrelin could be used to boost resistance to or even slow the development of Parkinson's disease. Parkinson's disease is caused by a degeneration...

Parkinson's Disease May Require a Combination of Factors

Parkinson's disease is a neurodegenerative disease that impairs movement and is characterized by a specific loss of dopamine neurons in a region of the midbrain called the substantia nigra (SN). Dopamine neurons in neighboring...

Gene Mutations Associated With Parkinson's Disease Risk Identified

Two studies to try to uncover genetic associations behind Parkinson's disease have found that people with certain gene mutations could have a higher risk of the disease. Parkinson's disease, which affects about 1.5 million...

Discovery Could Provide New Treatment Options for Parkinson's Disease

Researchers have found an essential key to possibly cure Parkinson's disease and are looking for others. The discovery is expected to provide new treatment options to stop the progression of Parkinson's disease or even...

Parkinson's Disease Risk 5 Times Greater for Gaucher Disease Carriers

According to a study by an international research team, carriers of a rare, genetic condition called Gaucher disease have a 5 times greater risk of developing Parkinson's disease. Previous studies have linked several genes...

Study Underway to Examine Benefits of Urate in Parkinson's Disease

According to a study, individuals with Parkinson's disease who have higher levels of urate in their blood and in cerebrospinal fluid have a slower rate of disease progression. A clinical trial is under way...

Genes Associated with Onset Age of Parkinson's Disease Identified

Genes which may influence the onset age of Parkinson's disease have been identified. The research is the first to identify genes contributing to the variation in onset age. Parkinson's disease incidence increases with age...

Parkinson's Disease Drivers Have Higher Crash Risk in Low Visibility

A study involving a driving simulation test shows that drivers with mild to moderate Parkinson's disease could be at higher risk of crashes on foggy days and other times of low visibility. Parkinson's disease...

Neurons Destroyed by Combination of 3 Molecules in Parkinson's Disease

Researchers have revealed that three molecules are responsible for neuron death in Parkinson's disease, providing a better understanding of how to save the neurons. The three molecules: the neurotransmitter dopamine, a calcium channel, and...

Phase 3 Trial of Coenzyme Q10 in Early Parkinson’s Disease is Underway

The effects of coenzyme Q10 (CoQ) in early Parkinson’s disease phase III trial is underway. Information gained from this trial could lead to changes in management of people with early Parkinson’s disease. A Phase...

Coenzyme Q10 Could Slow the Progression of Parkinson's Disease

Rush University Medical Center is participating in a large-scale, multi-center clinical trial to determine whether coenzyme Q10 in high doses can slow the progression of Parkinson's disease. Parkinson's disease is a neurodegenerative disorder that...
