Excessive manganese (Mn) accumulation in the brain may induce an extrapyramidal disorder known as manganism. Inflammatory processes play a critical role in neurodegenerative diseases. Therapeutically, non-steroidal anti-inflammatory drugs or analogous anti-inflammatory therapies have neuroprotective effects. As a non-steroidal anti-inflammatory drug, p-aminosalicylic acid (PAS) has anti-inflammatory effects, which are mediated by decreased prostaglandins E2 (PGE2) levels. The aim of the current study was to investigate whether PAS-Na treatment prevents Mn-induced behavioral changes and neuroinflammation in vivo...

Numerous studies have investigated aripiprazole as a treatment for bipolar disorder (BD). therefore we conducted this comprehensive meta-analysis to investigate the efficacy and safety profile of aripiprazole in treating BD. Two authors conducted systematic searches of PubMed and ScienceDirect from inception until May 14th, 2017. Randomized controlled trials (RCTs) of people with BD who received aripiprazole were included. A total of 20 RCTs met the eligibility criteria, including two which investigated the efficacy of aripiprazole versus haloperidol (aripiprazole=340; haloperidol=337), three which compared aripiprazole versus lithium (aripiprazole=208; lithium=212), and 15 with multiple comparisons of aripiprazole versus a placebo (aripiprazole=1923; placebo=1499)...

Selective serotonin reuptake inhibitors (SSRIs) have become one of the most broadly used medications in psychiatry. Fluoxetine is the first representative antidepressant SSRI drug approved by the Food and Drug Administration (FDA) in 1987. Safety information on fluoxetine use alone was less reported than its combined use with other drugs. There were no published papers on adverse drug reactions (ADRs) of fluoxetine analyzing spontaneous adverse events reports. We detected signals of the adverse drug reactions of fluoxetine by data mining using the Korea Adverse Events Reporting System (KAERS) database...

Neurodegeneration with brain iron accumulation (NBIA) is a heterogeneous group of inherited neurologic disorders with iron accumulation in the basal ganglia, which share magnetic resonance (MR) imaging characteristics, histopathologic and clinical features. According to the affected basal nuclei, clinical features include extrapyramidal movement disorders and varying degrees of intellectual disability status. The most common NBIA subtype is caused by pathogenic variants in PANK2. The hallmark of MR imaging in patients with PANK2 mutations is an eye-of-the-tiger sign in the globus pallidus...

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...

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: Schizophrenia is a chronic disease that requires long-term management with antipsychotics; however, an important barrier to the success of long-term treatment is drug noncompliance, which increases the risk of recurrence and hospitalization. Second-generation long-acting injectable antipsychotics have improved drug adherence, and the pharmacological effects of the drugs, and therefore, have become useful treatment options. METHODS: We report on three schizophrenia patients who switched from oral low-dose aripiprazole to aripiprazole once-monthly 300 mg...

Reports on the clinical presentation of adult-onset neuronal ceroid lipofuscinoses (NCL) are scarce compared to infantile- and childhood-onset forms. Here, we aimed to present detailed temporal evolution of clinical and electrophysiological features of two siblings with adult-onset NCL and homozygous mutation in the CLN6 gene. We retrospectively analysed medical records and electrophysiological data in order to delineate evolution of clinical and electrophysiological findings. Electrophysiological studies included routine EEG and video-EEG, as well as polymyographic analysis of myoclonus and brainstem reflex studies...

Recently, we identified a novel phosphodiesterase 2A (PDE2A) inhibitor, PDM-631 ((S)-3-cyclopropyl-6-methyl-1-(1-(4-(trifluoromethoxy)phenyl)propan-2-yl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one). PDM-631 showed potent inhibitory activities for human and rat PDE2A with IC50 values of 1.5 and 4.2nM, respectively and more than 2000-fold selectivity against other phosphodiesterases. In rat studies, PDM-631 showed oral bioavailability and good brain penetration, and increased the cGMP levels in the cortex...

Anticholinergic medications are used to treat extrapyramidal adverse effects induced by antipsychotics. Anticholinergics are associated with adverse effects: constipation, dry mouth and worsening of cognitive function. Anticholinergics have potential for abuse and are not recommended for long term-treatment. We aimed to investigate the use of anticholinergics in patients with schizophrenia. The national health registers in Denmark were used to examine: The prevalence of anticholinergics in 1996-2012 using a cross-sectional design; geographic variations in the prescription of anticholinergics in 2012; correlates of treatment with anticholinergics...

There has been a debate in the literature about the distinction between primary and secondary negative symptoms of schizophrenia. Our aim was to study the associations between negative symptoms and potential sources of secondary negative symptoms over time. A sample of 275 participants with at least mid-moderate negative symptoms was randomized into body psychotherapy or Pilates class in a previous study. No significant differences were found between groups over time and changes in the symptom domains were modest...

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...

Chronic manganese (Mn) exposure induces neurotoxicity, which is characterized by Parkinsonian symptoms resulting from impairment in the extrapyramidal motor system of the basal ganglia. Mitochondrial dysfunction and oxidative stress are considered key pathophysiological features of Mn neurotoxicity. Recent evidence suggests astrocytes as a major target of Mn neurotoxicity since Mn accumulates predominantly in astrocytes. However, the primary mechanisms underlying Mn-induced astroglial dysfunction and its role in metal neurotoxicity are not completely understood...

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...
