Neuro News Roundup: Parkinson or parkinsonian?

The highlights of new studies in neurology include: a single dose of aspirin, from 500 mg to 1000 mg, may reduce the use of rescue medications in adults with frequent episodic tension-type headache; blood neurofilament light chain (NfL) protein can discriminate between Parkinson disease and atypical parkinsonian disorder; and about half of patients with aggressive, treatment-refractory multiple sclerosis (MS) are free from neurological progression five years after autologous hematopoietic stem cell transplantation (AHSCT).
