Parkinson’s: New gene therapy shows promise for prevention

The hallmarks of Parkinson’s disease and some forms of dementia include Lewy bodies, toxic aggregates that form in the brain and disrupt neural circuits. Researchers from Osaka University in Japan are now testing a new preventive therapy in a preliminary mouse study. Researchers from Japan are testing out a new therapeutic approach for the prevention […]

Bipolar disorder may increase risk of Parkinson’s

A new study has found that people with bipolar disorder have a higher risk of developing Parkinson’s disease. Also, having bipolar disorder of a higher severity seems to increase the risk even further. A large-scale study finds links between bipolar disorder and Parkinson’s. Previous studies have found links between depression and Parkinson’s disease, but few […]

Using EEG data to diagnose Parkinson’s disease

Currently, diagnosis of Parkinson’s disease relies on a neurologist’s professional opinion. Researchers behind a new study believe that an EEG may be a more effective alternative. New research suggests that an EEG test could help diagnose Parkinson’s disease. Parkinson’s disease affects more than 10 million people worldwide, according to the Parkinson’s Foundation, but no scan […]

Study finds evidence of ‘clear relationship’ between appendectomy and Parkinson’s

An analysis of the health system records of more than 62 million people in the United States has found a link between appendix removal and raised risk of developing Parkinson’s disease. Is there a link between having an appendectomy and developing Parkinson’s disease? The researchers compared data on people who had undergone an appendectomy, or […]

Can a blood pressure drug protect the brain from Parkinson’s?

A prescription drug already in use for the treatment of high blood pressure could be effective against conditions such as Parkinson’s, Alzheimer’s, and Huntington’s, in which toxic proteins build up in brain cells. Scientists could repurpose felodipine to prevent Parkinson’s disease. Scientists at the University of Cambridge in the United Kingdom and the Guangzhou Institutes […]

Do people with Parkinson’s disease smell different?

Using the skills of a “super smeller,” researchers have identified how Parkinson’s disease alters the way a person smells. They hope that the discovery will help aid early diagnosis. A recent study investigated the links between odor and Parkinson’s. Parkinson’s is a progressive neurodegenerative condition. The National Institutes of Health (NIH) estimate that around half […]

Manganese and Parkinson’s: Mechanism may explain link

New research, published in the journal Science Signaling, details the mechanism through which exposure to manganese can trigger protein misfolding in the brain — which may, in turn, lead to Parkinson’s-like symptoms. The findings may enable an earlier diagnosis of the neurological condition. New research helps explain how and why manganese exposure could lead to […]

Parkinson’s: Study reveals how cancer drug reduces toxic protein in brain

Laboratory and animal studies have suggested that the leukemia drug nilotinib could alleviate symptoms of Parkinson’s disease. Now, using early results from a clinical trial in humans, scientists have worked out how the drug reduces toxic protein and raises dopamine levels in the brain. New research explains how a cancer drug increases levels of the […]

This sleep disorder puts people at ‘very high risk’ of Parkinson’s

Research has linked a particular sleep disorder called rapid eye movement (REM) sleep behavior disorder with a diagnosis of Parkinson’s disease. What characterizes this sleep problem, and can its presence be a good way to predict Parkinson’s risk? People who experience a sleep disorder that causes them to act out their dreams have a high […]
