OBJECTIVE: To test the efficacy of current treatment recommendations for parkinsonism and tardive dyskinesia (TD) severity in patients with severe mental illness (SMI). METHODS: We present an 18-year prospective study including all 223 patients with SMI (as defined by the 1987 US National Institute of Mental Health, which were based on DSM-III-R diagnostic criteria) receiving care from the only psychiatric hospital of the former Netherlands Antilles. Eight clinical assessments (1992-2009) focused on movement disorders and medication use...

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: Treatment of schizophrenia and major depressive disorder (MDD) with atypical antipsychotics (AAPs) show improved efficacy and reduced side effect burden compared with older antipsychotic medications. However, a risk of treatment-emergent adverse events (TEAEs) remains. TEAEs are hard to quantify and perspectives on the importance of TEAEs differ across patients and between patients and physicians. The current study is a qualitative assessment that investigates TEAEs of AAPs from both patient and physician perspectives to provide better understanding of the occurrence and burden of TEAEs associated with these medications...

BACKGROUND: Exertional heatstroke is a life-threatening condition with high mortality because of the rapid progress of multiple organ dysfunction syndrome even if aggressive treatments are initiated rapidly. Mild to moderate hepatic injury is common in exertional heatstroke, while fulminant liver failure is rare. Extrapyramidal symptoms and pulmonary aspergillosis secondary to liver failure induced by exertional heatstroke have never been reported in prior cases. CASE PRESENTATION: A 25-year-old Han Chinese man presented with exertional heatstroke with fulminant liver failure, subsequent pulmonary aspergillosis, and extrapyramidal symptoms...

Hereditary spastic paraplegias are heterogeneous neurodegenerative disorders characterized by progressive spasticity of the lower limbs due to degeneration of the corticospinal motor neurons. In a Bulgarian family with three siblings affected by complicated hereditary spastic paraplegia, we performed whole exome sequencing and homozygosity mapping and identified a homozygous p.Thr512Ile (c.1535C > T) mutation in ATP13A2. Molecular defects in this gene have been causally associated with Kufor-Rakeb syndrome (#606693), an autosomal recessive form of juvenile-onset parkinsonism, and neuronal ceroid lipofuscinosis (#606693), a neurodegenerative disorder characterized by the intracellular accumulation of autofluorescent lipopigments...

BACKGROUND: Frontotemporal lobar degeneration (FTLD) includes a spectrum of heterogeneous clinical and neuropathological diseases. In a strict sense this includes the behavioral variant of frontotemporal dementia (bvFTD) and primary progressive aphasia (PPA) and both variants can be associated with amyotrophic lateral sclerosis (FTD-ALS). In a broader sense FTLD also includes progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS). In recent years the strong genetic component of FTLD has become increasingly clear...

OBJECTIVES: Severe agitation is a common symptom in pediatric cases of anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis-an autoimmune encephalitis with prominent neuropsychiatric symptoms. Agitation is a major barrier to treatment of the underlying disease process and increases patients' risk of harming themselves and others. Furthermore, male patients often have undetectable tumors and are especially at risk for extended hospitalization, but have been infrequently studied...

REVIEW
Kirk A Frey
Extrapyramidal movement disorders including Parkinson disease, multiple systems atrophy, progressive supranuclear palsy, and corticobasal degeneration are neurodegenerative syndromes with distinct neuropathological changes, indicating differing underlying etiologies. Clinical features that may distinguish among these conditions are often absent, particularly early after the onset of symptoms. Therapy is presently limited, and there are no established disease-modifying or neuroprotective interventions. Advances in therapeutics will depend on the early and accurate diagnostic classification of patients...

We investigated the effects of simvastatin adjunctive therapy on the negative symptoms of schizophrenia. In this double-blind trial, inpatients with chronic schizophrenia were clinically stabilized on a constant dose of risperidone for at least 4 weeks before the study and were then randomized to receive risperidone (4-6 mg/day) plus either simvastatin (40 mg/day) (n=33) or placebo (n=33) for 8 weeks. The Positive and Negative Syndrome Scale was used to measure the negative, positive, and general symptoms of schizophrenia at baseline and every 2 weeks...

Parkinsonian-pyramidal syndrome (PPS) is an early onset form of Parkinson's disease (PD) that shows degeneration of the extrapyramidal region of the brain to result in a severe form of PD. The toxic protein build-up has been implicated in the onset of PPS. Protein removal is mediated by an intracellular proteasome complex: an E3 ubiquitin ligase, the targeting component, is essential for function. FBXO7 encodes the F-box component of the SCF E3 ubiquitin ligase linked to familial forms of PPS. The Drosophila melanogaster homologue nutcracker (ntc) and a binding partner, PI31, have been shown to be active in proteasome function...

OBJECTIVE: There has been no direct comparison of aripiprazole and blonanserin for schizophrenia treatment. We conducted a 24-week, rater-masked, randomized trial of aripiprazole (6-30 mg/d) vs blonanserin (4-24 mg/d) in schizophrenia patients who were not taking any antipsychotic medication for more than 2 weeks before enrollment (UMIN000011194). METHODS: The primary outcome measure for efficacy was improvement of Positive and Negative Syndrome Scale (PANSS) total score at week 24...

BACKGROUND: Creutzfeldt - Jakob disease (CJD) is a rapidly progressive and fatal neurodegenerative prion disease. MRI findings are included in diagnostic criteria for probable CJD, giving a sensitivity and specificity more than 90%, but the atypical radiological presentations in the early stage of the disease could cause the diagnostic difficulties. CJD can be definitively diagnosed by histopathological confirmation, brain biopsy or at autopsy. CASE PRESENTATION: We present a case of 53-year-old woman with a history of a rapidly progressive dementia with symptoms of visual impairment, increased extrapyramidal type muscle tonus, stereotypical movements and ataxic gait resulting in the patient's death after13 months...

Objective: Autosomal dominant cerebellar ataxia with deafness and narcolepsy (ADCA-DN) is an emerging syndrome caused by mutations in the C-terminus end of the TS domain of the DNMT1 gene. ADCA-DN is also associated with sensorimotor polyneuropathy, extrapyramidal, and dysautonomic signs, as well as dementia. Little has been reported about the progressive cognitive impairment associated with ADCA-DN. Our objective is to provide a detailed characterization of the cognitive profile of ADCA-DN. Method: Three members of a kindred with ADCA-DN underwent comprehensive neuropsychological testing and neuroimaging...

Importance: Zika virus infection can be prenatally passed from a pregnant woman to her fetus. There is sufficient evidence to conclude that intrauterine Zika virus infection is a cause of microcephaly and serious brain anomalies, but the full spectrum of anomalies has not been delineated. To inform pediatric clinicians who may be called on to evaluate and treat affected infants and children, we review the most recent evidence to better characterize congenital Zika syndrome. Observations: We reviewed published reports of congenital anomalies occurring in fetuses or infants with presumed or laboratory-confirmed intrauterine Zika virus infection...

OBJECTIVE: While doctors often increase the dose of an antipsychotic when there is insufficient response, there is limited evidence that this intervention is any better than waiting longer on the lower dose. We put the proposition to test. METHOD: In this 4-week, double-blind, randomized controlled trial conducted in psychiatric care from September 2012 to March 2015, 103 patients with schizophrenia (ICD-10) who did not respond to olanzapine 10 mg/d or risperidone 3 mg/d were randomly allocated to a dose-increment or -continuation group...

We report the early growth and neurologic findings of 48 infants in Brazil diagnosed with probable congenital Zika virus syndrome and followed to age 1-8 months. Most of these infants had microcephaly (86.7%) and craniofacial disproportion (95.8%). The clinical pattern included poor head growth with increasingly negative z-scores, pyramidal/extrapyramidal symptoms, and epilepsy.

PURPOSE: Cyamemazine (Tercian(®)) is currently the most widely prescribed neuroleptic in France. This widespread use is due to its anxiolytics properties and to a claimed good safety profile. Although, prescription of cyamemazine is not devoid of the risks associated with the use of neuroleptics: extrapyramidal syndromes. This study aims at describing extrapyramidal syndromes induced by cyamemazine registered in the French pharmacovigilance database. METHODS: All spontaneous reports of extrapyramidal syndromes in the French pharmacovigilance database between 1st January 1985 and 31th December 2015 were described and analyzed...

Intravenous use of a psychostimulant drug containing methcathinone (ephedrone) and manganese causes an irreversible extrapyramidal syndrome in drug abusers. We aimed to reproduce the syndrome in mice to evaluate dopaminergic damage. C57/B6 mice were intraperitoneally injected once a day with the study drug or saline for a period of 27 weeks. Motor activity was recorded in an automated motility-box. After 13 and 27 weeks of treatment, ex vivo digital autoradiography was performed using [11C]dihydrotetrabenazine ([11C]DTBZ)...
