Older age at disease onset is associated with greater motor and nonmotor impairment in people with idiopathic Parkinson’s disease, according to a study by scientists in Luxembourg. Nonmotor symptoms such as urinary incontinence and apathy in those diagnosed at older ages were found to be mainly driven by the natural…

Experiencing a traumatic brain injury (TBI) is associated with an earlier age of Parkinson’s onset, but not with more severe disease-associated nerve cell loss or younger age of death, a study suggests. These findings, presented at the 2021 Alzheimer’s Association International Conference in Denver and online, suggest that…

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…

Later age at Parkinson’s disease onset is associated with high adherence to the MIND diet and benefits women more than three times as much as it does men, a study has shown.  In contrast, adherence to the Greek Mediterranean diet significantly correlates…

A point mutation in a gene involved in dopamine synthesis is linked to Parkinson’s disease characteristics but only in younger patients, suggesting that age modifies the impact of the gene. This finding may provide new leads in the search for mechanisms causing Parkinson’s disease, particularly in patients who fall ill at…

People carrying the most common Parkinson’s disease-related mutation in the LRRK2 gene may start showing symptoms at an earlier age if they also have a mutation in another gene. The findings prompted researchers to suggest that tests for this newly identified mutation could be valuable for genetic counseling of LRRK2…
