Increased use of antibiotics may predispose to Parkinson’s disease
Excessive exposure to certain antibiotics can predispose a person to Parkinson's disease, with a delay of onset of up to 15 years.... Read More...

Fecal transplantation to treat patients with Parkinson’s disease: Hope or hype?
Study reflects on the possible use of fecal microbiome transplants and pre/probiotics to help with the treatment of Parkinson's disease. Findings reveal fecal transplants have not yet been proven to be effective for motor symptoms associated with the condition, and probiotics have only been shown to assist with constipation....

Targeting alpha-synuclein in the gut may slow down Parkinson’s disease
Scientists are conducting experiments to see if targeting the enteric nervous system with a compound can inhibit the aggregation of alpha-synuclein and slow the progression of Parkinson's disease.... Read More...
Inflammatory bowel disease appears to impact risk of Parkinson’s disease
Study provides new insights into how the immune system and inflammation play a role in the development and progression of Parkinson's disease.... Read More...
What do we know about the gut microbiota in Parkinson’s disease?
Researchers propose future gut microbiome studies related to Parkinson's disease should address questions relevant to patient care.... Read More...
Where does Parkinson’s disease start? In the brain or gut? Or both?
Lewy body disorders, including Parkinson's disease and Lewy body dementia, comprise of two distinct subtypes. One subtype originates in the peripheral nervous system (PNS) of the gut and spreads to the brain. The other originates in the brain, or enters the brain via the olfactory system, before spreading to the brainstem and PNS.... Read More...
Exposure to environmental PCBs impairs brain function in mice
Polychlorinated biphenyls (PCBs), chemicals commonly used during the 20th century as flame retardants and in industrial products, disrupt the performance of astrocytes, leading to impaired function. Environmental exposure to PCBs could contribute to a range of neurodegenerative diseases.... Read More...
Is bipolar disorder associated with increased risk of Parkinson’s disease?
Study reveals patients with bipolar disorder have a significantly increased risk of developing Parkinson's disease compared with the general population.... Read More...
Parkinson’s disease is also present in the blood
Parkinson's disease involves monocytic alterations in the blood. The cells have reduced viability and are unresponsive to specific stimuli, which could have relevant consequences for the progression of Parkinson's. Immune modulation medications may be a new treatment option to inhibit neurodegeneration associated with PD.... Read More...

How and why does Parkinson’s disease affect women and men differently?
Study highlights the role estrogen plays in the differences in the progression of Parkinson's disease between men and women.... Read More...
Genes associated with left-handedness linked with shape of the brain’s language regions
Four genetic regions have been identified as playing a role in left-handedness. Three of the four genes were associated with proteins involved in brain development and structure. Neuroimaging revealed those who were left-handed had increased functional connectivity between left and right language networks. Researchers also found correlations between the genetic regions associated with left-handedness and slightly reduced Parkinson's risk, but a slightly increased risk for schizophrenia.... Read More...
