REVIEW
Helle Stangeland, Vasiliki Orgeta, Vaughan Bell
A preregistered systematic review of poststroke psychosis examining clinical characteristics, prevalence, diagnostic procedures, lesion location, treatments, risk factors and outcome. Neuropsychiatric outcomes following stroke are common and severely impact quality of life. No previous reviews have focused on poststroke psychosis despite clear clinical need. CINAHL, MEDLINE and PsychINFO were searched for studies on poststroke psychosis published between 1975 and 2016. Reviewers independently selected studies for inclusion, extracted data and rated study quality...

INTRODUCTION: Aim of the study was to characterize the clinical spectrum of long-term treated patients with Wilson's disease (WD) and to identify risk factors influencing long-term outcome. METHODS: In a cross-sectional study 30 WD-patients being treated for at least 2.5 and up to 31 years underwent a detailed clinical investigation, scoring of clinical findings yielding 7 motor and 3 non-motor subscores as well as laboratory testing. A factor analysis of these subscores and laboratory parameters was performed to detect those items with the highest influence on outcome, an ANOVA and subgroup analysis tested the influence of age, age at onset of diagnosis and duration of treatment on outcome...

Increasing evidence has suggested that depression is a neuropsychiatric condition associated with neuroplasticity within specific brain regions. However, the mechanisms by which neuroplasticity exerts its effects in depression remain largely uncharacterized. In the present study we show that chronic stress effectively induces depression-like behaviors in rats, an effect which was associated with structural changes in dendritic spines and synapse abnormalities within neurons of the ventromedial prefrontal cortex (vmPFC)...

Neuropsychiatric disorders are associated with neurological soft signs (NSS), including motor, sensory, and inhibitory dysfunction. The present study aims at determining the prevalence of NSS and explore the association of sociodemographic characteristics with the occurrence of NSS in patients with bipolar disorder and unipolar depression compared to healthy controls. A case-control study included a sample of 50 bipolar and unipolar patients and 50 healthy controls. NSS subscales of the Neurological Evaluation Scale (NES) were administered to each participant...

Systemic lupus erythematosus (SLE) or Lupus is a chronic and idiopathic autoimmune connective tissue disease that involves several organs and organ systems. SLE may lead to a group of psychiatric manifestations, including delirium, anxiety disorders, cognitive dysfunction, mood disorders, and psychosis, which are caused by organic or non-organic factors. In addition, it is thought that the most common cause of neuropsychiatric lupus is corticosteroid use; central nervous system involvement and inflammatory processes also have an important role in the development of psychiatric manifestations...

Mutations in presenilin 1 (PSEN1) are the most common cause of autosomal dominant Alzheimer's disease. Here, we report a Canadian-Vietnamese family carrying a PSEN1 p.Met233Val mutation with an exceptionally early and severe presentation that includes a wide range of atypical symptoms, including prominent ataxia, Parkinsonism, spasticity, dystonia, action tremor, myoclonus, bulbar symptoms, seizures, hallucinations and behavioral changes. Whole-exome sequencing (WES) was performed on the affected proband after many assessments over several years proved diagnostically inconclusive...

Dysregulation of prefrontal cortical glutamatergic signalling via NMDA receptor hypofunction has been implicated in cognitive dysfunction and impaired inhibitory control in such neuropsychiatric disorders as schizophrenia, attention deficit hyperactivity disorder and drug addiction. Although NMDA receptors functionally interact with metabotropic glutamate receptor 5 (mGluR5), the consequence of this interaction for glutamate release in the prefrontal cortex (PFC) is unknown. We therefore investigated the effects of positive and negative allosteric mGluR5 modulation on changes in extracellular glutamate efflux in the medial PFC (mPFC) induced by systemic administration of the non-competitive NMDA receptor antagonist dizocilpine (or MK801) in rats...

Motor inhibition is a cognitive control ability that allows humans to rapidly stop actions even after initiation. Understanding and improving motor inhibition could benefit adaptive behavior in both health and disease. We recently found that presenting surprising, task-unrelated sounds when stopping is necessary improves the likelihood of successful stopping. In the current study, we investigated the neural underpinnings of this effect. Specifically, we tested whether surprise-related stopping improvements are due to a genuine increase in motor inhibition...

Antibody-mediated encephalopathies associated with serum or cerebrospinal fluid antibodies directed against neuronal structures may present with a multitude of neuropsychiatric syndromes. Although some of the antibody-driven conditions are now well recognized in adults (eg, N-methyl-D-aspartate receptor antibody encephalitis), the spectrum of neuropsychiatric manifestations in the pediatric population is less clear. Psychosis, confusion, catatonia, and additional behavioral changes, along with seizures, encephalopathy, and movement disorders, may be initial manifestations or concurrent features in all age groups...

The ability to flexibly switch between goal-directed actions and habits is critical for adaptive behavior. The infralimbic prefrontal cortex (IfL-C) has been consistently identified as a crucial structure for the regulation of response strategies. To investigate the role of the IfL-C, the present study employed two validated reinforcement schedules that either promote habits or goal-directed actions in mice. The results reveal that information about action-outcome relationships is differentially encoded in the IfL-C during actions and habits as evidenced by encoding of behavioral outcomes during goal-directed actions that is lost during habits...

It is generally accepted that inflammation plays a key role in anxiety and depression induced by diabetes. However, the underlying mechanism and effective treatment method of these diabetes-associated behavior disorders remain to be determined. In the present study, we attempted to illuminate the implication of zeaxanthin in anxiety, depression and neuroinflammation caused by hyperglycemia, and further elaborate the relevant mechanism under these neuropsychiatric disorders. In the current work, diabetic rats were induced by high glucose and fat diet followed by a single intraperitoneal injection of streptozocin, and zeaxanthin was orally administration every day (From 6th to 19th week)...

INTRODUCTION: Whipple's disease (WD) is a chronic, multisystemic infectious disease caused by Gram-positive bacillus Tropheryma whipplei (T.w.). Its common symptoms arise in the digestive system, however, during the infection the CNS (Central Nervous System) may also be affected. AIM: The aim of this work is to present a case report of a patient diagnosed with Whipple's disease with dominant neuropsychological and behavioural complications in the late phase. CONCLUSIONS: Whipple's disease is a rare disease with possible neurological and neuropsychiatric complications...

BACKGROUND: The brain-derived neurotrophic factor (BDNF) Val66Met polymorphism (rs6265) has been associated with several neuropsychiatric disorders and regional structural brain changes in adults, but little is known about Val66Met's effect on brain morphology during typical or atypical neurodevelopment. Windows of vulnerability to psychopathology may be associated with the different alleles of the Val66Met polymorphism during childhood and adolescence. METHODOLOGY: We investigated the effect of Val66Met on cortical thickness in MRI scans of 718 children and adolescents (6-12 years old) with typical development, and in those meeting DSM criteria for a psychiatric disorder...

BACKGROUND: Ganglioglioma is a rare, benign, intraaxial glioneuronal tumor, but a relatively common cause of pharmacoresistant temporal lobe epilepsy (TLE). Given its often nonspecific neuropsychiatric manifestations and frequently negative electroencephalographic workup, TLE can be easily misdiagnosed as a psychiatric disorder, particularly panic attacks. CASE DESCRIPTION: We present a case of a 17-year old boy who was found to have lesional TLE secondary to a left temporal ganglioglioma, 5 years after having been misdiagnosed with panic disorder and undergone ineffective and unnecessary psychotherapy...

GABAergic cortical interneurons are a heterogeneous population of cells that play critical roles in regulating the output of excitatory pyramidal neurons as well as synchronizing the outputs of pyramidal neuron ensembles. Deficits in interneuron function have been implicated in a variety of neuropsychiatric disorders, including schizophrenia, autism, and epilepsy. The derivation of cortical interneurons from embryonic stem cells not only allows for the study of their development and function, but provides insight into the molecular mechanisms underlying the pathogenesis of cortical interneuron-related disorders...

BACKGROUND: Alzheimer's disease (AD) is the most common cause of dementia. However, none of medical treatment can stop or reverse the underlying neurodegenerative of AD at present. Acupuncture has attracted more and more attention in recent years due to its efficacy and very few side effects. Lately, a systematic review has thought that the evidence on the effectiveness of acupuncture in improving the cognitive function of AD patients was not powerful enough. Therefore, the aim of this study is to explore the efficacy and safety of acupuncture in patients with mild to moderate AD...

REVIEW
Makoto Naoi, Wakako Maruyama, Masayo Shamoto-Nagai
Type A and B monoamine oxidases (MAO-A, -B) mediate and modulate intracellular signal pathways for survival or death of neuronal cells. MAO-A is associated with development of neuronal architecture, synaptic activity, and onset of psychiatric disorders, including depression, and antisocial aggressive impulsive behaviors. MAO-B produces hydrogen peroxide and plays a vital role in neuronal loss of neurodegenerative disorders, such as Parkinson's and Alzheimer's diseases. This review presents a novel role of MAO-A and B, their substrates and inhibitors, and hydrogen peroxide in brain function and neuronal survival and death...
