Study of the Effectiveness of Valbenazine on Patient- and Clinician-Reported Outcomes in Participants...
SchizophreniaSchizoaffective Disorder3 moreThis study will evaluate the effectiveness of valbenazine on patient- and clinician-reported outcomes assessing health-related quality of life, functioning, and treatment effect in participants with tardive dyskinesia (TD) who are receiving valbenazine for up to 24 weeks.
Smoking Cessation With Varenicline in Schizophrenia: Antipsychotic-Induced Neurological Symptoms...
SchizophreniaSchizoaffective Disorder3 moreTo test the feasibility of studying effects of smoking cessation with varenicline on antipsychotic drug-induced neurological side effects, we propose a 12 week pilot study of smoking cessation treatment with varenicline in 10 schizophrenia or schizoaffective disorder patients who are actively smoking and have pre-existing TD while receiving stable doses of antipsychotics. Subjects will be followed after a 2 week baseline period to assess changes in smoking status and neurological symptoms using standardized rating scales. The aim is to examine clinically significant effects on antipsychotic-induced neurological side effects that may warrant further investigation.

Movement DisordersEssential Tremor7 moreThe proposed study is to evaluate the effectiveness of ExAblate Transcranial MRgFUS as a tool for creating a unilateral lesion in the Vim thalamus or the globus pallidus (GPi) in patients with treatment-refractory symptoms of movement disorders.
Remote Monitoring and Detecting of Tardive Dyskinesia for Improving Patient Outcomes
Tardive DyskinesiaThe study is being conducted to validate the feasibility of remote assessment of Tardive Dyskinesia.
Reduction of Demoralization After Treatment of TD With Valbenazine
Tardive DyskinesiaThe purpose of this research project is to determine the feasibility of a larger study aimed at demonstrating that treatment of tardive dyskinesia with Valbenazine is associated with reduction of demoralization
Sarizotan in the Treatment of Neuroleptic-induced Tardive Dyskinesia
Neuroleptic-induced Tardive DyskinesiaTD is a troublesome and potentially irreversible side effect associated with the use of neuroleptics. While the newer neuroleptics are improved in this regard, they all still carry the risk of TD. The present study proposes that sarizotan is a potential agent for treating neuroleptic-induced TD based on preliminary data indicating efficacy in the management of dyskinesias associated with Parkinson's disease. Its efficacy is further substantiated by pre-clinical data obtained from the vacuous chewing movement (VCM) model in rats, a model we employ ourselves in investigating the relationship between D2 occupancy and TD. The present study also examines the effects of sarizotan on cognitive function, given the association between TD and cognitive deficits.
Safety and Efficacy of Pyridoxal 5' -Phosphate in the Treatment of Tardive Dyskinesia
Tardive DyskinesiaThe primary objective is to assess the safety and effectiveness of Pyridoxal 5'-Phosphate on the reduction of expressed symptoms of tardive dyskinesia in patients with schizophrenia and schizoaffective disorders.
Validation of the Implantation of a New Electrode for the Treatment of Dystonia
Generalized DystoniaSegmental Dystonia1 moreThe main objective of the trial is to study the technical feasibility of the implantation of a new electrode Monocontact deep brain stimulation electrode in dystonia.
Deep Brain Stimulation for Patients With Tardive Dyskinesia and or Dystonia
Tardive DyskinesiaTardive DystoniaRationale: Tardive dyskinesia and dystonia (TDD) are severe side effects of dopamine blocking agents, particularly antipsychotics. Deep brain stimulation (DBS) has shown to be effective in the treatment of TDD in psychiatric patients, but only reported in case reports and small clinical trials and with little attention to possible psychiatric or cognitive complications or positive effect on psychiatric symptoms. Objective: To assess whether treatment with DBS can reduce or resolve TDD and if DBS can induce beneficial or side-effects in particular psychiatric symptoms. Study design: A delayed onset double blind randomised controlled trial. Study population: Adult patients with a current or previous psychiatric disorder and antipsychotic induced TDD with a stable psychiatric status during the past 6 months. Intervention: All patients will be treated with DBS in the posteroventrolateral GPi. The groups will be randomised into immediate stimulation or delayed stimulation after 3 months. Main study parameters/endpoints: Primary objective, improvement on the movement rating scales BFMDRS. Secondary objectives improvement on the quality of life measured on the SF-36, psychiatric stability as measured on the BPRS and the MADRS and cognitive effects as measured on the MATTIS Dementia Rating Scale, Nederlandse Leestest voor Volwassenen (NLV), 15 word test, Facial Expression of Emotion S+T (FEEST), Groninger Intelligentie Test woordopnoemen (GIT), category and letter fluency test, Trail Making Test part A and B and the Stroop colour and word test
