by Ziba Kashef, Yale University Treatments for Parkinson’s disease have most recently focused on increasing dopamine, a chemical messenger in the brain that affects reward-based behaviors and motivation, as well as movement. A new study by Yale researchers challenges long-held assumptions about dopamine’s sole role in this disorder. In people with Parkinson’s disease, nerve cells that produce dopamine slowly die. The loss...

New findings can help Parkinson’s patients
Posted Today This news or article is intended for readers with certain scientific or professional knowledge in the field. For patients with Parkinson’s disease, early signs of a certain part of the brain being broken down has been shown to have a negative impact on the course of the disease. The results of a study which researchers from...

New brain imaging study reveals signs of Parkinson’s decades before symptoms appear
Rich Haridy A new study from King’s College London upends conventional thinking about the origins of Parkinson’s disease in the brain. The research reveals distinct changes in the brain’s serotonin system can be identified up to 20 years before any Parkinson’s symptoms appear, suggesting a new biomarker to detect the disease at its earliest stages....

How ultrasound could help curb Parkinson’s
By Catharine Paddock PhD Fact checked by Carolyn Robertson There are two major stumbling blocks to developing effective drugs for Alzheimer’s, Parkinson’s, and other diseases that destroy the brain. The first is overcoming the blood-brain barrier, and the second is delivering the drug to a precise location and ensuring that it does not spread to...

Device continuously monitors the symptoms of patients with Parkinson’s
by Universitat Politècnica de Catalunya Until now, the lack of precise, continuous data on the clinical status of individuals affected by Parkinson’s disease throughout the day was one of the main difficulties faced by neurologists in charge of adapting treatment. Now, this obstacle has been overcome with a new device called STAT-ON. It is a small sensor held in...

More evidence that blood tests can detect the risk of Alzheimer’s
by Lund University A new study confirms that a simple blood test can reveal whether there is accelerating nerve cell damage in the brain. The researchers analysed neurofilament light protein (NFL) in blood samples from patients with Alzheimer’s disease. Recently published in JAMA Neurology, the study suggests that the NFL concentration in the blood could be able to indicate if a drug actually affects the loss of...

Scientists found a way to restore motivation of people with Parkinson’s
Incurable diseases distort people’s world view. It is a very well-known fact that people who suffer from Parkinson’s lose all their motivation. However, now scientists from the Monash University proved that dopamine levels in the brain can help people with Parkinson’s disease to combat cognitive apathy and regain cognitive motivation equivalent to healthy individuals. Dopamine...

Motorized finger-bender designed to detect Parkinson’s disease
Ben Coxworth Because it doesn’t show up in either blood tests or brain scans, Parkinson’s disease can be frustratingly difficult to diagnose. A new device could help, however, by repeatedly bending the patient’s finger. It may make diagnoses easier, and allow treatment to start earlier. Developed at Melbourne, Australia’s Bionics Institute, the tool is known as the Bionics Institute Rigidity Device...
