Tardive dyskinesia (TD) occurs in patients receiving antipsychotic treatment with dopamine receptor antagonists. Despite the prevalence of TD and its negative impact on patients' lives, there has been a lack of approved treatments and limited evidence from controlled trials of pharmacological treatment. Areas covered: PubMed was searched for English-language papers published during 2007-2016 using terms "tardive dyskinesia" or "drug-induced movement disorder", and "treatment". Studies evaluating pharmacological agents for the treatment of TD were selected...

INTRODUCTION: The pathophysiology of pain in migraine is related to the activation of the trigeminovascular system by releasing vasoactive neuropeptides, the most important of which is calcitonin gene-related peptide (CGRP), which causes a neurogenic inflammation in the leptomeningeal vessels. AIM: To study whether CGRP is increased in frequent episodic migraine and whether preventive treatment with topiramate or zonisamide modifies its levels. SUBJECTS AND METHODS: We studied 28 patients with episodic migraine with or without aura, in accordance with the International Headache Society criteria, with a frequency of 4-14 days/month...

BACKGROUND: Epilepsy is a common neurological condition with a worldwide prevalence of around 1%. Approximately 60% to 70% of people with epilepsy will achieve a longer-term remission from seizures, and most achieve that remission shortly after starting antiepileptic drug treatment. Most people with epilepsy are treated with a single antiepileptic drug (monotherapy) and current guidelines from the National Institute for Health and Care Excellence (NICE) in the United Kingdom for adults and children recommend carbamazepine or lamotrigine as first-line treatment for partial onset seizures and sodium valproate for generalised onset seizures; however a range of other antiepileptic drug (AED) treatments are available, and evidence is needed regarding their comparative effectiveness in order to inform treatment choices...

Zonisamide (ZNS) is an effective drug for not only motor symptoms but also non-motor symptoms in Parkinson's disease. However, the actions of ZNS as an anti-Parkinsonian drug are not well understood. To clarify the actions of ZNS in vivo, we administered ZNS to mice and examined the effects on neurotransmitter metabolism and behaviors, focusing on motor and non-motor symptoms. Administration of ZNS decreased dopamine (DA) turnover in various brain regions, including the striatum. In behavioral tests, ZNS enhanced locomotor activity and novelty seeking in the open field test, light-dark transition test, and the social interaction test...

This study was proposed to compare the relative efficacy and tolerability of the second and third generation AEDs for refractory epilepsy. The 50% responder rate (RR) was selected as the efficacy outcome whereas the incidence of dizziness and somnolence were considered to evaluate the tolerability of AEDs. Odds ratio (OR) and their 95% credible interval (CrI) were obtained using a consistency model and surface under the cumulative ranking curve (SUCRA) value was calculated to rank AEDs. Topiramate appeared to be significantly more effective than placebo, eslicarbazepine acetate, perampanel, pregabalin, zonisamide, gabapentin and lamotrigine with respect to the 50% RR (all OR > 1)...
