Migraines, obsessive-compulsive disorder, and seasonal allergies seem to be associated with Parkinson’s disease and are likely to occur many years before the typical age of diagnosis, a large study has found. Results of the study, “The Parkinson’s phenome—traits associated with Parkinson’s disease in a broadly phenotyped cohort,” were…

Two new studies in mice suggest that caffeine might have protective effects in the brains of Parkinson’s disease patients. The studies, “Chronic Caffeine Treatment Modulates  Disease Progression in a Transgenic Alpha-Synuclein Prion-Like Spreading Mouse Model of Parkinson’s Disease,” and “Chronic Caffeine Treatment Reverses A-Synuclein-Induced…

Parkinson’s patients who have had the disease for a long time, who do not sleep very efficiently, and have higher motor impairment are more likely to experience sleep benefit — the phenomenon in which Parkinson’s patients wake up feeling better before taking medication. The study with that finding, “…
