An older age at diagnosis, but also reduced physical activity due to medical or social conditions, were significantly linked with faster motor decline in people with  Parkinson’s disease, a Japanese study has found. According to its authors, maintaining daily physical activity and allowing patients to move freely is paramount…

Carrying the G2385R variant in the LRRK2 gene is associated with a three times higher risk of developing Parkinson’s disease among Chinese adults older than 50, according to a 10-year population-based study. Carriers of this mutation who were not diagnosed with Parkinson’s showed a trend toward greater motor…

In the United States, the prevalence of Parkinson’s disease is higher in states with more lead pipes that carry water to households, according to a new study. The results add to a growing body of evidence that exposure to lead could increase the risk of developing Parkinson’s. The…

People with age-related macular degeneration, an eye disease that blurs central vision, may have a higher risk of developing Parkinson’s disease, a Taiwanese population‐based retrospective study suggests. The study, ‘Increased risk of Parkinson’s disease among patients with age-related macular degeneration,” was published in the journal BMC Ophthalmology. Age-related…

Having longer-than-normal fatty molecules and an inactive enzyme called cathepsin-B in nerve cells’ recycling centers may increase the risk of developing Parkinson’s disease in people with mutations in the GBA1 gene, the disease’s most common genetic risk factor. This is the hypothesis generated by a recent study, titled “Pathological…

Gout does not increase the risk of developing Parkinson’s disease, according to an analysis based on insurance data in Korea. The analysis indicates, however, that people who have had a stroke and those with high blood pressure might have a higher Parkinson’s risk. Results were published in the study “…

People with Parkinson’s disease caused by mutations in the LRRK2 gene have a higher risk of stroke relative to other groups of Parkinson’s patients and healthy individuals, according to a study from Spain. These findings add to previous studies reporting a link between Parkinson’s and increased stroke risk, and…

People with the most common form of arthritis, osteoarthritis, may be at increased risk of developing Parkinson’s disease, according to a study from the U.K. This result is in line with an earlier study from Taiwan. Based on these findings, “measures aiming at the prevention of Parkinson’s disease should be…

People with Parkinson’s disease are significantly less likely than those without the neurodegenerative disorder to develop colorectal cancer, a type of cancer that begins in the final part of the digestive tract, a new meta-analysis suggests. In fact, the analysis showed that the risk of developing such cancer…

The use of non-steroidal anti-inflammatory drugs (NSAIDs) seems to have no effect on the incidence of Parkinson’s disease, according to a large retrospective Norwegian study. Researchers focused on the NSAIDs prescribed most in Norway: diclofenac, ibuprofen, and naproxen. In the study “NSAID use is not associated with Parkinson’s…
