PURPOSE/BACKGROUND: Antipsychotics are efficacious for tics and are increasingly prescribed to children with behavioral disorders. Antipsychotics have important adverse effects, and systematic monitoring of drug safety is infrequently performed. The objectives of this study were to determine the feasibility of antipsychotic safety monitoring in children with Tourette Syndrome using a defined protocol and to evaluate the risk of adverse effects with chronic use. METHODS/PROCEDURES: A prospective longitudinal study of children prescribed antipsychotics was performed...

RATIONALE: Long-acting injectable (LAI) paliperidone palmitate 1-month formulation (PP1M) has demonstrated acceptable tolerability and favorable clinical outcomes in Western and Asian patients with schizophrenia. Hence, analysis of the outcomes of long-term PP1M treatment specifically in Chinese patients is of interest. OBJECTIVE: The aim of this study is to evaluate the long-term safety and efficacy of PP1M treatment in Chinese patients with schizophrenia. METHODS: In this 25-week, open-label, Phase IV study, patients (18-65 years) diagnosed with schizophrenia and having a baseline Positive and Negative Syndrome Scale (PANSS) total score of 60-120 (inclusive) were enrolled...

In the last years second-generation antipsychotics are increasingly prescribed in the pediatric population for the treatment of several psychiatric disorders. Among the long term adverse effects, extrapyramidal symptoms (EPS) are less reported compared to first-generation antipsychotics. Tardive dyskinesia (TD) is a iatrogenic rare syndrome characterized by persistent slow writhing and sudden involuntary movements mainly involving the oral-buccal-lingual area with masticatory movements. We report a young girl with mood disorders accompanied by mild intellectual disability and behavioral problems who had TD after treatment with Aripiprazole, which responded to Biperiden therapy...

Ying Liang, Xin Yu
BACKGROUND: Effective management strategies for the negative symptoms of schizophrenia remain an unmet need, and data on the use of antipsychotics in this population are scarce, particularly in Chinese patients. Therefore, we investigated amisulpride for the treatment of Chinese patients with predominantly negative symptoms of schizophrenia. METHODS: This post hoc subanalysis of the prospective Effectiveness and Safety of Amisulpride in Chinese Patients with Schizophrenia (ESCAPE) study included adult Chinese patients with an International Classification of Diseases-10 diagnosis of schizophrenia and predominantly negative symptoms, who received amisulpride for 8 weeks...

Acquired hepatocerebral degeneration is a neurological syndrome with typical clinical (extrapyramidal and neuropsychiatric) symptoms and brain magnetic resonance imaging findings (high T1 signal in the globus pallidus). It occurs mainly in patients with advanced liver disease, such as in patients co-infected with hepatitis B virus (HBV) and hepatitis delta virus (HDV). However, there are no reports relating HBV/HDV coinfection and acquired hepatocerebral degeneration. This report presents the case of a 49-year-old woman with characteristics of acquired hepatocerebral degeneration and liver cirrhosis due to HBV/HDV coinfection, and presents the main theories of the physiopathology of this condition...

Background It has been recently suggested that second-generation antipsychotic long-acting injection (SGA-LAIs) are underutilized in clinical practice, despite that their costs significantly impact on national health system budgets. Hence, an updated analysis of safety data shown by SGA-LAIs may contribute to clarify their role in clinical practice. Materials and methods English-language, peer-reviewed articles reporting updated, primary findings on the SGA-LAI safety were identified (updated through an electronic search of five databases - PubMed, EMBASE, PsycInfo, DARE and the Cochrane Library)...

Previous studies of patients with brain damage have suggested a close relationship between aphasia and movement disorders. Neurodegenerative extrapyramidal syndromes associated with cognitive impairment provide an interesting model for studying the neural substrates of cognitive and motor symptoms. In this review, we focused on studies investigating language production abilities in patients with Parkinson's disease (PD), Corticobasal Syndrome (CBS) and Progressive Supranuclear Palsy (PSP). According to some reports, these patients exhibit a reduction in performance in both action and object naming or verb production compared to healthy individuals...

BACKGROUND: Some patients present an unusual association of both action tremor (AT) and rest tremor (RT) making the differential diagnosis between essential tremor (ET) and Parkinson's disease (PD) difficult. AIM: To investigate this particular clinical picture trying to focus on possible peculiar clinical inferences. PATIENTS AND METHODS: Twenty-three patients with atypical tremor syndrome were selected for the study. They underwent neurological examination, neuroimaging study, and brain DaTSCAN single-photon emission computed tomography...

Despite the high prevalence of viral hepatic cirrhosis all over the world, the characteristic motor features of related Parkinsonism (extrapyramidal manifestations) are not well described. The current study aimed to characterize such disorder in a sample of Egyptian patients with chronic viral liver disease (CLD), and their clinical correlates. METHODS: Ninety-six (96) patients with CLD were examined for presence of extrapyramidal signs. Parkinsonism was assessed using the UPDRS-III scale and its sub scores...

BACKGROUND: The relative efficacy and tolerability of antipsychotics for schizophrenia are considerably well studied. This study aimed to examine whether previous findings could be replicated in a genetically distinct and homogenous group (ie, Japanese patients with schizophrenia) and whether previous findings could be extended to a broader range of antipsychotics with previously unclear relative efficacy and tolerability. METHODS: Bayesian network meta-analysis was performed in which randomized trials comparing any of the following interventions were included: second-generation antipsychotics, haloperidol, or placebo...

Neuroleptic malignant syndrome (NMS) is a rare but life-threatening idiosyncratic side effect resulting from neuroleptic drugs. NMS mainly occurs in patients treated with high-potency typical antipsychotics, but rarely caused by atypical antipsychotics. Although NMS is less common with atypical antipsychotic, but it seems that its incidence is rising due to increased administration of such drugs. We present the case of a 27-year-old man with a history of paranoid schizophrenia that showed signs consistent with NMS that occurred after treatment with olanzapine...

Amantadine, which was originally developed as an antiviral medication, functions as a dopamine agonist in the central nervous system and consequently is utilized in the treatment of Parkinson disease, drug-induced extrapyramidal reactions, and neuroleptic malignant syndrome. For reasons that are not entirely understood, abrupt changes in amantadine dosage can produce a severe withdrawal syndrome. Existing medical literature describes case reports of amantadine withdrawal leading to delirium, which at times has progressed to neuroleptic malignant syndrome...

Gerstmann-Sträussler-Scheinker (GSS) syndrome is a fatal autosomal dominant neurodegenerative prionopathy clinically characterized by ataxia, spastic paraparesis, extrapyramidal signs and dementia. In some GSS familiar cases carrying point mutations in the PRNP gene, patients also showed comorbid tauopathy leading to mixed pathologies. In this study we developed an induced pluripotent stem (iPS) cell model derived from fibroblasts of a GSS patient harboring the Y218N PRNP mutation, as well as an age-matched healthy control...

Antipsychotic drugs block dopamine receptors and are used to manage psychosis as well as other mental illnesses that may or may not have psychotic features, such as bipolar disorders and major depressive disorder. First-generation antipsychotic drugs are more likely to cause adverse effects such as extrapyramidal symptoms and tardive dyskinesia. Adverse effects of second-generation antipsychotic drugs typically are related to metabolic abnormalities such as weight gain, abnormal blood glucose levels, and elevated lipid levels...

The treatment of schizophrenia is challenging due to the wide range of symptoms (positive, negative, cognitive) associated with the disease. Typical antipsychotics that antagonize D2 receptors are effective in treating positive symptoms, but extrapyramidal side-effects (EPS) are a common occurrence. Atypical antipsychotics targeting 5-TH2A and D2 receptors are more effective at treating cognitive and negative symptoms compared to typical antipsychotics, but these drugs also result in side-effects such as metabolic syndromes...
