Randomized Controlled TrialComparison of the efficacy of azathioprine and rituximab in neuromyelitis optica spectrum disorder: a randomized clinical trial.
Neuromyelitis optica spectrum disorder (NMOSD) often follows a relapsing course. As disability in NMOSD is attack-related, effective treatments are needed. We aimed to compare the efficacy of azathioprine (AZA) and rituximab (RIT) as maintenance therapy in NMOSD patients. ⋯ AZA and RIT can both effectively decrease ARR and EDSS in NMOSD patients. RIT was significantly more effective than AZA treatment. Trial Registration Name of registry: clinicaltrials.gov; ID: NCT03002038; URL: https://clinicaltrials.gov/ct2/show/NCT03002038 .

Randomized Controlled TrialBrain plasticity in Parkinson's disease with freezing of gait induced by action observation training.
Gait disorders represent a therapeutic challenge in Parkinson's disease (PD). This study investigated the efficacy of 4-week action observation training (AOT) on disease severity, freezing of gait and motor abilities in PD, and evaluated treatment-related brain functional changes. 25 PD patients with freezing of gait were randomized into two groups: AOT (action observation combined with practicing the observed actions) and "Landscape" (same physical training combined with landscape-videos observation). At baseline and 4-week, patients underwent clinical evaluation and fMRI. ⋯ In AOT group, functional brain changes were associated with clinical improvements at 4-week and predicted clinical evolution at 8-week. AOT has a more lasting effect in improving motor function, gait and quality of life in PD patients relative to physical therapy alone. AOT-related performance gains are associated with an increased recruitment of motor regions and fronto-parietal mirror neuron and attentional control areas.

Randomized Controlled TrialEfficacy of single versus three sessions of high rate repetitive transcranial magnetic stimulation in chronic migraine and tension-type headache.
We report the efficacy of three versus single session of 10 Hz repetitive transcranial magnetic stimulation (rTMS) in chronic migraine (CM) and chronic tension-type headache (CTTH). Ninety-eight patients with CM or CTTH were included and their headache frequency, severity, functional disability and number of abortive medications were noted. Fifty-two patients were randomly assigned to group I (three true sessions) and 46 to group II (one true and two sham rTMS sessions) treatment. 10 Hz rTMS comprising 600 pulses was delivered in 412.4 s on the left frontal cortex. ⋯ In group II, these were 24 (64.8 %) and 22 (59.2 %), respectively. In chronic migraine, the severity of headache at 2 months reduced in group I compared to group II (62.5 vs 35.3 %; P = 0.01). Both single and three sessions of 10 Hz rTMS were found to be equally effective in CM and CTTH, and resulted in conversion of chronic to episodic headache in 67.1 % patients.

Randomized Controlled TrialComparative effects of unilateral and bilateral subthalamic nucleus deep brain stimulation on gait kinematics in Parkinson's disease: a randomized, blinded study.
Gait dysfunction in Parkinson's disease (PD) does not always respond to bilateral subthalamic nucleus deep brain stimulation (STN-DBS). Since right hemisphere motor networks may be dominant for gait control, identical stimulation of asymmetric circuits could account for gait dysfunction. We compared the effects of bilateral and unilateral STN-DBS on gait kinematics in PD patients who developed gait impairment after STN-DBS. ⋯ Yet, unilateral stimulation has similar effects on gait kinematics. Particularly, right-sided stimulation might produce slightly greater improvements. Although the clinical relevance of differential programming of right versus left-sided STN-DBS is unclear, this approach could be considered in the management of treatment-resistant gait dysfunction in PD.

Randomized Controlled TrialBrief intervention by general practitioners for medication-overuse headache, follow-up after 6 months: a pragmatic cluster-randomised controlled trial.
Medication-overuse headache (MOH) is a common health problem. Withdrawal of the overused medication is the treatment of choice. We investigated the long-term effectiveness of brief intervention (BI) for MOH patients in primary care. The BI for MOH in primary care study was a blinded, pragmatic, cluster-randomised controlled trial. 25,486 patients (age 18-50) from 50 general practitioners (GPs) were screened for MOH. GPs defined clusters and 23 GPs were randomised to receive BI training and 27 GPs to continue business as usual (BAU). The GPs assessed their MOH patients with the Severity of Dependence Scale, gave individual feedback about the risk of MOH and advice to reduce headache medication. Primary outcomes, assessed 6 months after the intervention, were reduction in headache and medication days/month. 42% were screening responders. 2.4% had self-reported MOH. A random selection of 104 patients with self-reported MOH were invited, 75 were randomised out of which 60 with a physician-defined MOH diagnosis were included. None were lost to follow-up. BI was significantly better than BAU regarding primary outcomes (p < 0.001-0.018). Headache and medication days were reduced by 5.9 (95% CI 1.1-10.8) and 6.2 (1.1-11.3) more days/month in BI than BAU group. Chronic headache resolved in 63 and 11% in the BI and the BAU group (p < 0.001). Headache-related disability was lower among those who detoxified. In conclusion, BI is an effective treatment in primary care with lasting effect 6 months after the intervention for MOH.
