OBJECTIVES: Previous "Treatment of Severe Childhood Aggression" (TOSCA) reports demonstrated that many children with severe physical aggression and attention-deficit/hyperactivity disorder (ADHD) responded well to two randomized treatments (parent training [PT]+stimulant+placebo = Basic vs. PT+stimulant+risperidone = Augmented) for 9 weeks. An important clinical question is whether these favorable outcomes are maintained over longer times. METHODS: Clinical responders to the 9-week trial (n = 103/168), defined as Clinical Global Impressions (CGI)-Improvement of much/very much improved plus substantial reduction in parent ratings of disruptiveness, were followed another 12 weeks (21 weeks total) while remaining on blinded treatment...

BACKGROUND: Tardive dyskinesia (TD) is a condition that was first described nearly 60 years ago. Despite the tremendous amount of research on pathophysiology and numerous follow-up studies to understand the course and prognosis of TD, effective treatment of the condition continued to elude us until recently. METHODS: We review and summarize clinical literature on TD, as well as provide an update on new treatments available. RESULTS: The emergence of tetrabenazine as a treatment modality decreased suffering and improved quality of life for patients...

Anti-N-methyl-d-aspartate antibody receptor (NMDAR) encephalitis is a newly recognized disease increasing in diagnostic frequency. A 27-year-old female presented with symptoms of oral dyskinesia, tachycardia, and altered mental status following a three-month history of depression, lethargy, catatonia, and auditory hallucinations. We utilized our facilities neurology and psychiatry consult services, performed a lumbar puncture (LP), and requested NMDAR antibody titers. Following admission the Anti-NMDAR antibody titer was elevated warranting treatment with intravenous immunoglobulin (IVIG), corticosteroids, and later rituximab...

Rationale The standard approach to diagnosis of primary ciliary dyskinesia (PCD) in the UK consists of assessing ciliary function by high-speed-microscopy and ultrastructure by election microscopy, but equipment and expertise is not widely available internationally. The identification of bi-allelic disease causing mutations is also diagnostic, but many disease causing genes are unknown, and testing is not widely available outside the USA. Fluorescent antibodies to ciliary proteins are used to validate research genetic studies, but diagnostic utility in this disease has not been systematically evaluated...

Antipsychotics are commonly prescribed in the general population since they have many indications. They can be used in acute care such as agitation or behavior disorders, or to treat more characterized psychiatric disorders like psychotic or mood disorders. Consequently, any practitioner will have to prescribe or renew a prescription of antipsychotics. These treatments require a benefit/risk balance assessment taking into account the specific context of each patient. Indeed, antipsychotics have many side effects, mainly neurological (extrapyramidal syndrome, dyskinesia, akathisia), metabolic and cardiac...

BACKGROUND: Schizophrenia remains a major health problem despite antipsychotic medications that, for most patients, can decrease acute symptoms, decrease relapses, and contribute to partial and sometimes strong positive response in patients with chronic symptoms. What has not been clear-because a double-blind, randomized, placebo-controlled trial is not feasible or ethical-is how many years after the initial episode, or onset of antipsychotic treatment, should medication be continued to achieve the best global outcome...

BACKGROUND: In Australia 1% of individuals aged over 50 years have Parkinson's disease (PD). AIMS: Guidance for commencing device-assisted therapies (DATs) for PD in Australia was developed based on a review of European recommendations and their relevance to the local clinical setting. METHODS: An online survey and teleconference discussions were held by a group of eight local movement disorder experts to develop consensus. RESULTS: Referral to a movement disorder specialist and consideration of DAT is appropriate when motor fluctuations cause disability or reduced quality of life, response to treatment is inconsistent or motor fluctuations and dyskinesias require frequent treatment adjustment without apparent benefit and levodopa is required four or more times daily...

Accumulating studies reported mutations in the gene encoding the proline-rich transmembrane protein 2 (PRRT2) to be causative for several paroxysmal neurological disorders, including paroxysmal kinesigenic dyskinesia (PKD), PKD combined with infantile seizures (ICCA), and benign familial infantile seizures (BFIS). However, the impact of PRRT2 in tumorigenesis is not known. Based on a large-scale data analysis, we found that PRRT2 was down-regulated in glioma tumor tissues compared with normal brain tissue. Dysregulation of PRRT2 was not induced by mutation, copy number variation and epigenetic modification, but modulated by microRNA-30a-5p...

Paroxysmal dyskinesias (PDs) are a group of hyperkinetic movement disorders characterised by circumscribed episodes of disturbed movement, superimposed on a background state in which such abnormality is absent. There is no loss of consciousness. Episodes can last seconds, minutes or hours, and the beginning and end of the movement disturbance are abrupt. Neurological examination is typically normal between episodes. PDs are associated with a broad spectrum of clinical presentations, encompassing various aetiologies...

BACKGROUND: Levodopa/carbidopa intestinal gel therapy (LCIG) can efficiently improve several motor and non-motor symptoms of advanced Parkinson's disease (PD). The recently developed Movement Disorder Society-sponsored Unified Parkinson's Disease Rating Scale (MDS-UPDRS) improved the original UPDRS making it a more robust tool to evaluate therapeutic changes. However, previous studies have not used the MDS-UPDRS and the Unified Dyskinesia Rating Scale (UDysRS) to assess the efficacy of LCIG...

PURPOSE: Primary ciliary dyskinesia (PCD) is a respiratory syndrome in which 'random' organ orientation can occur; with approximately 46% of patients developing situs inversus totalis at organogenesis. The aim of this study was to explore the relationship between organ anatomy and curve convexity by studying the prevalence and convexity of idiopathic scoliosis in PCD patients with and without situs inversus. METHODS: Chest radiographs of PCD patients were systematically screened for existence of significant lateral spinal deviation using the Cobb angle...

By moving essential body fluids and molecules, motile cilia and flagella govern respiratory mucociliary clearance, laterality determination and the transport of gametes and cerebrospinal fluid. Primary ciliary dyskinesia (PCD) is an autosomal recessive disorder frequently caused by non-assembly of dynein arm motors into cilia and flagella axonemes. Before their import into cilia and flagella, multi-subunit axonemal dynein arms are thought to be stabilized and pre-assembled in the cytoplasm through a DNAAF2-DNAAF4-HSP90 complex akin to the HSP90 co-chaperone R2TP complex...

Long-term therapy of Parkinson's disease with L‑DOPA is associated with a high risk of developing motor fluctuations and dyskinesia. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) can improve these motor complications. Although the positive effect on motor symptoms has been proven, postoperative cognitive decline has been documented. To tackle the impact of DBS on cognition, 18 DBS patients were compared to 25 best medically treated Parkinson's patients, 24 patients with mild cognitive impairment (MCI) and 12 healthy controls using the Neuropsychological Test Battery Vienna short version (NTBV-short) for cognitive outcome 12 months after the first examination...

Outcome of imipramine (IMI) treatment was scrutinized on progression of haloperidol instigated tardive dyskinesia (TD). 0.2 mg/kg/rat dosage of haloperidol provided orally to rats for 2 weeks enhanced vacuous chewing movements that escalated when the process proceeded for 5 weeks. Following 2 weeks co-injection 5 mg/kg dosage of IMI was diminished haloperidol-instigated VCMs and fully averted following five weeks. The potency of 8-OH-DPAT-instigated locomotor activity exhibited higher in saline+haloperidol treated rats while not observed in IMI+ haloperidol treated rats...

Access to the CNS and delivery of therapeutics across the blood-brain barrier remains a challenge for most treatments of major neurological diseases such as AD or PD. Focused ultrasound represents a potential approach for overcoming these barriers to treating AD and PD and perhaps other neurological diseases. Ultrasound (US) is best known for its imaging capabilities of organs in the periphery, but various arrangements of the transducers producing the acoustic signal allow the energy to be precisely focused (F) within the skull...
