Comparative StudyEffects of low-frequency repetitive transcranial magnetic stimulation of the contralesional primary motor cortex on movement kinematics and neural activity in subcortical stroke.
Following the concept of interhemispheric competition, downregulation of the contralesional primary motor cortex (M1) may improve the dexterity of the affected hand after stroke. ⋯ The functional magnetic resonance imaging data suggest that rTMS of the contralesional M1 may normalize neural activation within the cortical motor network after subcortical stroke. Identifying patients suitable for rTMS intervention based on individual patterns of cortical activation may help to implement rTMS in motor rehabilitation after stroke.

Randomized Controlled Trial Comparative StudySerum urate as a predictor of clinical and radiographic progression in Parkinson disease.
To determine whether concentration of serum urate, a purine metabolite and potent antioxidant that has been linked to a reduced risk of Parkinson disease (PD), predicts prognosis in PD. ⋯ These findings identify serum urate as the first molecular factor directly linked to the progression of typical PD and suggest that targeting urate or its determinants could be an effective disease-modifying therapy in PD. Trial Registration clinicaltrials.gov Identifier: NCT00040404.

Case ReportsAn elderly patient with Bickerstaff brainstem encephalitis and transient episodes of brainstem dysfunction.
Bickerstaff brainstem encephalitis (BBE) is a rare inflammatory, demyelinating disease that generally has a good prognosis. ⋯ Bickerstaff brainstem encephalitis is a potentially reversible syndrome that needs early diagnosis (facilitated by magnetic resonance imaging) and prompt aggressive and supportive treatment. Frequent episodes of transient brainstem dysfunction occurred in our patient during recovery, possibly due to ephaptic transmission.
