A new transgenic Parkinson’s disease mouse model is able to recapitulate the motor symptoms and biological causes of disease, including alpha-synuclein protein aggregation, a study reports. Similar to Parkinson’s patients, this model also responds to levodopa, one of the main compounds used to treat symptoms of the disease. The study, “Abrogating Native…
One in two women and one in three men older than 45 will develop Parkinson’s disease, dementia or stroke during their lifetime, a new study suggests. Preventive strategies to delay disease onset can reduce this risk by up to half. The study with those findings, “Lifetime risk of common neurological…
People with inflammatory bowel disease (IBD), an umbrella name for disorders marked by prolonged inflammation of the digestive tract, are at a higher-than-usual risk for Parkinson’s disease, a review study involving 8.9 million IBD patients suggests. The study, “The risk of Parkinson’s disease in inflammatory bowel disease: A…
People diagnosed with attention deficit/hyperactivity disorder (ADHD), usually detected at an early age in hyperactive children, may have an increased risk of developing Parkinson’s and Parkinson’s-like diseases, a new study suggests. “Parkinson’s disease is commonly thought of as a neurodegenerative disease associated with aging,” Glen Hanson, PhD, professor at the…
A well-known monkey model for Parkinson’s disease — used mainly for its ability to mimic human motor symptoms — can also reflect the disease’s non-motor symptoms, including sleep disturbances, changes in the body’s natural clock, and cognitive impairment, a study shows. These results highlight the usefulness of…
A fish that can sense the Earth’s magnetic field while it swims could help scientists understand how the human brain works and eventually unlock strategies to help control movement impairments in patients with Parkinson’s disease and other neurological disorders, a study reports. The study, “Wireless control of cellular function by…
The Parkinson’s Foundation announced that it investing $6.2 million across 53 research grants, part of its commitment to advancing promising work into the disease. The grants will support Parkinson’s clinical trials and research centers. They also include career development and fellowships for scientists working in multiple aspects of related research. “Our goal at…
“Traffic jams” that occur along nerve cells in the brain and disrupt the transport of mitochondria were found to be a significant cause of Parkinson’s disease, a study reports. In particular, researchers found that alpha-synuclein protein aggregates, the hallmark of Parkinson’s, impair the movement of mitochondria, which provide…
A Phase 1 trial will test the potential of ketamine — an analgesic medicine used for depression and pain — at reducing the uncontrollable, jerky movements that arise in Parkinson’s disease patients after long-term treatment with levopoda. Levodopa, probably the most common treatment for Parkinson’s disease, is effective at improving the stiffness…
A new chemical probe that binds to a protein called DJ-1 — a sensor of oxidative stress and a potential biomarker of Parkinson’s disease — may help researchers understand how the protein participates in disease progression, a study suggests. The study, “A chemical probe to monitor the parkinsonism-…
