The recognition of the antibody-mediated encephalitis as a separate entity among the immune disorders of the central nervous system was one of the greatest breakthroughs of the last two decades in neurology. Unlike viral or tumor-related encephalitis, the antibody-mediated form has a good response to immunotherapy, which gives a special clinical importance to the discovery. Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is one of the first fully characterized antibody-mediated encephalitises. This article attempts to summarize the clinical features of this complex neuropsychiatric disorder with the aim to help its early recognition and to report the clinical course and the outcome of our six seropositive anti-NMDAR cases...

The neuropsychiatric examination includes standard neurological and cognitive examination techniques with several additional observations and tasks designed to capture abnormalities common among patients with neuropsychiatric disorders or neurocognitive complaints. Although useful as a screening tool, a single standardized rating scale such as the Mini Mental State Examination (MMSE) or the Montreal Cognitive Assessment (MoCA) is insufficient to establish a neuropsychiatric diagnosis. Extra attention is paid to findings commonly seen in the setting of psychiatric disorders, dementias, movement disorders, or dysfunction of cortical or subcortical structures...

BACKGROUND: Creutzfeldt-Jakob disease is a rare and rapidly fatal neurodegenerative disease. Since clinicians may see only very few cases during their professional career, it is important to be familiar with the clinical presentation and progression, to perform appropriate investigations, and allow for quick diagnosis. CASE PRESENTATION: A 73-year-old British Caucasian woman presented with acute confusion of 2 weeks' duration on a background of low mood following a recent bereavement...

Delirium is an acute neuropsychiatric syndrome which is common in elderly patients during their hospitalisation and is associated with an increased mortality and morbidity. Since delirium is a) often underdiagnosed and b) preventable if early signs are detected,igh expectations are set in delirium risk assessment during hospital admission. In our latest studies, we showed that delirium prediction using machine learning algorithms is possible based on the patients' health history. The aim of this study is to compare the influence of nursing assessment data on prediction models with clinical and demographic data...

Nitrous Oxide, which is also called laughing gas, now ranks as the 7th most popular drug in the world. Nitrous oxide mainly disturbs B12 metabolism and damages nerves, followed by apparent neuropsychiatric symptoms. It's beneficial to the prognosis of patients if we identify and treat their symptoms early. This case report describes a 19-year-old male who presented with auditory hallucination, persecutory delusions and unstable emotions after abuse of nitrous oxide over the course of half a year. Moreover, neurological signs such as weakness and hyperesthesia also appeared...

Pseudo-Cushing's syndrome covers different pathological conditions responsible for mild-to-moderate ACTH-dependent hypercortisolism, related not to an ACTH-secreting tumor but rather to CRH and/or AVP hypothalamic secretion through activation of various neural pathways, in patients generally displaying excess central adiposity. It is better termed "non-neoplastic hypercortisolism" (NNH). The main conditions implicated in NNH comprise: neuropsychiatric disorder, alcohol abuse, insulin-resistant obesity, polycystic ovary syndrome, and end-stage kidney disease...

BACKGROUND: Hepatic encephalopathy may manifest by a wide spectrum of neuropsychiatric symptoms, including cognitive impairment, seizures or extrapyramidal symptoms. The liver transplant can lead to improvement of the signs of encephalopathy but subsequent immunosuppressive treatment might possess pronounced neurotoxicity. CASE PRESENTATION: We present a case report of a patient with chronic liver disease who developed signs of Parkinsonism after an orthotopic liver transplant, with consecutive immunosuppressant treatment with tacrolimus...

BACKGROUND: Wilson disease is a rare genetic disorder in which impaired copper excretion results in toxic copper levels and tissue damage. Manifestations are primarily hepatic and/or neuropsychiatric, with a variety of neurological phenotypes. The aim of this study was to characterize neurological signs of Wilson disease in newly diagnosed patients and to determine whether they correlated with disability, liver function, and copper metabolism. METHODS: Fifty-three treatment-naïve patients recently diagnosed with Wilson disease who exhibited neurological symptoms were included...

Kleine-Levin syndrome (KLS) is a rare, relapsing-remitting disease that affects mostly adolescents. It is characterized by episodes lasting from 1 to several weeks, and comprises neurological (hypersomnia, confusion, slowness, amnesia) and neuropsychiatric symptoms (derealization and apathy). Some psychiatric symptoms (megaphagia, hypersexuality, anxiety, depressed mood, hallucinations, delusions) arise during episodes, albeit less frequently, while patients are normal between episodes. However, sudden severe (>18h/day of sleep) and recurrent hypersomnia helps to differentiate KLS from other psychiatric mimics...

Behavioral disorders occupy the crossroads between neurology and psychiatry, and emerging disorders, such as frontotemporal lobar degeneration of genetic origin and autoimmune encephalitis, can present with both neurological and psychiatric signs. Thus, the primary aim of this introductory article is to review frequently encountered behavioral clinical features, such as apathy and agitation, and their related syndromes, including frontal and anterior temporal syndromes. These behavioral states and their underlying etiologies are also here illustrated with clinical case reports...

Background: Joubert syndrome (JS) is a rare, autosomal recessively inherited genetic disorder characterized morphologically by unique developmental malformations of the cerebellum and brainstem (the molar tooth sign), and clinically by impaired motor functions and intellectual disability. Patients with JS often face multiple cognitive challenges, but the neuropsychological profile of this condition has not been well characterized. Methods: We performed comprehensive neurological and neuropsychological evaluations in three adult brothers with JS, ages 32, 27, and 25 years...

BACKGROUND: Visual scales may be particularly useful in screening for depression in patients with low literacy. However, few have been validated and none are in common use.AimModification and validation of a visual scale to screen for depression in low literacy settings. METHOD: We assessed the validity, reliability and factor loading of a 28-item visual depression inventory using pictorial items depicting depression signs and symptoms. We validated a revised scale comprised of 18 items known as the Akena Visual Depression Inventory (AViDI-18) against a structured diagnostic interview (Mini-International Neuropsychiatric Inventory) in 343 patients in Kampala (Uganda) and Cape Town (South Africa)...

E M Peter-Ross
The pathobiological causes, the shared cellular and molecular pathways in catatonia and in catatonic presentation in neuropsychiatric disorders are yet to be determined. The hypotheses in this paper have been deduced from the latest scientific research findings and clinical observations of patients with genetic disorders, behavioral phenotypes and other family members suffering mental disorders. The first hypothesis postulates that catatonia and the heterogeneity of catatonic signs and symptoms involve nucleolar dysfunction arising from abnormalities of the brain-specific, non-coding micro-RNA, SNORD115 genes (either duplications or deletions) which result in pathobiological dysfunction of various combinations in the downstream pathways (possibly along with other genes in these shared pathways)...

Since many years a correlation between neuropsychiatric disorders and eating disorders resulting in obesity is well established. According to different studies, 1.2 - 4 % of patients scheduled for bariatric surgery are taking lithium as a mood stabilizer treatment for bipolar disorder. We are presenting a case of lithium toxicity after vertical sleeve gastrectomy surgery in a 40 years-old female. The patient developed severe neurological and renal signs needing an intensive care unit admission and continuous veno-venous hemodiafiltration...

Inflammatory processes may be involved in the pathophysiology of neuropsychiatric illnesses including autism spectrum disorder (ASD). Evidence from studies in rodents indicates that immune activation during early development can produce core features of ASD (social interaction deficits, dysregulation of communication, increases in stereotyped behaviors, and anxiety), although the neural mechanisms of these effects are not thoroughly understood. We treated timed-pregnant mice with polyinosinic:polycytidylic acid (Poly I:C), which simulates a viral infection, or vehicle on gestational day 12...

BACKGROUND: Elderly persons with a dementia diagnosis often suffer from different neuropsychiatric symptoms (NPS) such as delusions, hallucinations, depression, anxiety, irritability and agitation. Currently, the medical treatment for NPS consists mostly of psychotropic medication such as hypnotics/sedatives, anxiolytics and antipsychotics. In elderly persons with dementia, usage of antipsychotics is less appropriate because of the risk of side effects such as parkinsonism, rapid cognitive decline, cerebrovascular events and finally mortality...

Hallervorden-Spatz syndrome is a rare neurodegenerative disorder with hereditary properties. It usually occurs in young adolescents with extrapyramidal symptoms besides disturbed mental function. In this study, we present a 23-year-old neuropsychiatric patient who primarily misdiagnosed to have conversion disorder. She had 5-year history of progressive dysarthria and generalized abnormal movements. After detecting the pathognomonic sign of "eye of the tiger" diagnosis was confirmed. The patient was discharged...

We present a case of myoclonus-dystonia syndrome illustrated by three videos in which we found a novel SGCE mutation. As the patient described here was suffering from predominant psychiatric comorbidities it took more than 40 years from the first manifestation of the disease until the diagnosis. Having detected the genetically proven cause for his motor and non-motor symptoms was an enormous relief to our patient. We want to share this instructive case in order to prompt neurologists and psychiatrists to look closely at both movement disorders and neuropsychiatric signs in order to diagnose and treat patients to the latest standard...
