Scientists discover the root of Parkinson’s disease


The latest research by scientists from VIB-KU Leuven in Belgium has led to the discovery that a faulty stress-coping mechanism in the brain could be the root cause of Parkinson’s disease. The team, led by Professor Patrik Verstreken, a specialist in brain research, found that the genetic mutations at the root of Parkinson’s can reduce the ability of the synapses to cope with ...

Scientists recreate the start and spread of Parkinson’s in the brain


Two of the most asked questions surrounding Parkinson’s disease are, where does it start and is it possible to stop it in the early stages? Now scientists from the Van Andel Research Institute have developed a new model of Parkinson’s which clearly demonstrates how the abnormal alpha-synuclein proteins gradually work their way from the areas of the brain known to ...

Scientists gain further insights into cause of Parkinson’s via human brain recordings


Researchers from Emory University in Atlanta have been successful in systematically recording neural activity within the striatum of the human brain.   The striatum is a deep brain structure that’s known to play a major role in both cognitive and motor function. In Parkinson’s disease, both of these functions are compromised leading to issues with neuron-firing which in turn affects ...

Could a new treatment slow down the progression of Parkinson’s disease?


New research carried out by scientists at the University of Alabama could mean that we’re one step closer to developing a treatment to slow down the progression of Parkinson’s disease. During their study, the researchers discovered that a mutant gene interacts with the alpha synuclein in neurons to cause the typical pathologies seen in the disease. These findings give rise ...

Scientists identify the neurochemical signal likely to be missing in Parkinson’s disease

Brain Activity

Two neuroscientists from Northwestern University have identified the neurochemical signal that’s likely to be missing in people with Parkinson’s. They’re also the first researchers to discover that there are two distinct populations of neurons that deliver dopamine to the brain. Until this discovery it was thought that all dopamine neurons were involved in both movement and reward. However, scientists began ...

How laxatives can tell us more about Parkinson’s


Researchers from King’s College London have just undertaken a retrospective study to review laxative use among 79 patients with Parkinson’s disease. Each of the patients had been part of a gut-brain clinic that ran between August 2002 and July 2014. The results of the analysis showed that a combination of gut factors are linked to the disease mechanisms of Parkinson’s. ...

Scientists find a new tissue marker for Parkinson’s disease and Dementia with Lewy Bodies

Being able to accurately diagnose Parkinson’s disease and Dementia with Lewy bodies can prove to be very difficult during the early stages of the diseases. While it is possible to diagnose both by performing a brain biopsy, due to the risk of complications this is not a viable option, and both diseases are usually diagnosed via an autopsy following death. ...
