Treatment with psilocybin — the hallucinogenic agent in magic mushrooms — may help to prevent damage to the brain following mild head injuries, according to a new study done in rats. Head injuries are an established risk factor for Parkinson’s disease, as well as Alzheimer’s and other…
In people with Parkinson’s disease, the cerebral cortex of the brain can compensate for disease-related dysfunction in the basal ganglia, the main part of the brain affected by Parkinson’s. Researchers found that patients with milder Parkinson’s symptoms have more compensatory activity in the cerebral cortex, while patients with…
Patterns of brain damage in Parkinson’s disease differ based on whether or not individuals have REM sleep behavior disorder (RBD), a new study suggests. Study findings indicate that patterns of brain damage are similar among Parkinson’s patients who develop RBD before or after Parkinson’s motor symptoms. Based on…
Using ultrasound coupled with the intravenous injection of microbubbles lessened brain damage in a mouse model of early Parkinson’s and may provide a noninvasive way to successfully deliver therapies into the brains of people with the disease, a study reports. A clinical trial with Alzheimer’s disease patients has been…
Quantifying changes in fluid in a specific brain area, using a magnetic resonance imaging (MRI)-based method, could provide a way to track brain damage in patients with Parkinson’s disease, a new study suggests. The study, “Progression marker of Parkinson’s disease: a 4-year multi-site imaging study,” appeared in the journal Brain.
