Dopamine-Resistant Tremors Caused by Abnormal Brain Activity, Study Finds

Parkinson’s patients whose tremors respond poorly to dopaminergic medications are likely experiencing abnormal brain activity outside the brain’s dopaminergic system, a study finds. The results, “Cerebral differences between dopamine-resistant and dopamine-responsive Parkinson’s tremor,” were published in the journal Brain. The main cause of motor…

IL-17A Accelerates Brain Inflammation and Degeneration in Animal Models of Parkinson’s, Study Finds

Interleukin-17A (IL-17A) — a molecule that is involved in immune and inflammatory responses — accelerates brain inflammation and degeneration in animal models of Parkinson’s disease, a study has found. The research, “IL-17A exacerbates neuroinflammation and neurodegeneration by activating microglia in rodent models of Parkinson’s disease,” was published in…
