We present an atypical case of relapsed anti-NMDAR encephalitis in a young female patient without an associated ovarian teratoma. She presented with recurrent seizure attacks with muscle weakness, psychosis, dyskinesia, autonomic failure and insomnia. She was first misdiagnosed as mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) then Hashimoto's encephalopathy due to diffuse cerebral lesions, elevated serum lactic acid concentration, increased amount of thyroid peroxidase and thyroglobulin antibodies in serum and diffuse lesions of the thyroid gland...

BACKGROUND: Childhood trauma increases risk of a range of mental disorders including psychosis. Whereas the mechanisms are unclear, previous evidence has implicated atypical processing of emotions among the core cognitive models, in particular suggesting altered attentional allocation towards negative stimuli and increased negativity bias. Here, we tested the association between childhood trauma and brain activation during emotional face processing in patients diagnosed with psychosis continuum disorders...

Parkinson disease psychosis (PDP) is a common phenomenon in Parkinson disease (PD) patients treated with dopaminergic drugs, and is associated with high morbidity and mortality. It also correlates with depression and dementia, and can contribute to considerable caregiver stress and burnout. While symptoms can be relieved by decreasing doses or number of anti-PD medications, this may lead to an unacceptable worsening of motor function. When general medical or psychiatric conditions have been ruled out, and decreasing dopaminergic agents is not effective in treating psychosis, therapies include atypical antipsychotics, primarily clozapine and quetiapine...

Chromosome 22q11.2 deletion syndrome (22q11.2DS) is a complex developmental disorder with serious medical, cognitive and emotional symptoms across the lifespan. This genetic deletion also imparts a lifetime risk for developing schizophrenia that is 25-30 times that of the general population. The origin of this risk is multifactorial and may include dysregulation of the stress response and immunological systems in relation to brain development. Vitamin D is involved in brain development and neuroprotection, gene transcription, immunological regulation and influences neuronal signal transduction...

Parkinson's disease (PD) is a progressive neurodegenerative disorder with both motor and nonmotor symptoms (NMS), leading to significant morbidity and caregiver burden. Psychosis is common but is under recognized by physicians. When present, it increases the patient's risk of hospitalization and nursing home placement and caregiver burden. Although the atypical antipsychotic agent, clozapine, has been considered the gold standard treatment, severe agranulocytosis in 0.38% of patients and more commonly milder leukopenia, resulting in frequent blood testing, limit its use...

Parkinson's disease (PD) is a progressive neurodegenerative disorder with prominent motor and non-motor symptoms. Psychosis develops in over 40% of PD patients and it is one of the most distressing symptoms for patients and caregivers alike. Until recently, atypical antipsychotics, clozapine and quetiapine were used to treat psychotic symptoms, but treatment was associated with substantial concerns for side-effects of clozapine and unfounded efficacy for quetiapine. Extensive research has shown that the antipsychotic effect of these drugs could be attributed to serotonin 2a receptor (5 HT2a) triggered mechanisms...

New-onset psychotic symptoms often respond well to antipsychotic treatment; however, symptoms may be difficult to treat when an underlying brain malformation is present. Here, we present a case of atypical psychotic symptoms in the context of a congenital cerebellar malformation (Dandy-Walker variant). The patient ultimately improved with paliperidone palmitate after multiple antipsychotic medication trials (both oral and one long-acting injectable) were ineffective. Neuroimaging may provide valuable diagnostic and prognostic information in cases of new-onset psychosis with atypical features and treatment resistance, even in the absence of neurologic signs and symptoms...

Psychosis in Parkinson's disease (PD) is one of the greatest determinants of nursing home placement and caregiver stress. Traditionally associated with medications with dopaminergic effect, it has now been linked to other medications and other stressors e.g. systemic illnesses. The development of hallucinations in a PD patient can herald the onset of dementia and usually predicts increased mortality risk. Medication reduction in PD psychosis usually reduces the symptoms; however, this comes at the cost of worsening motor function...

Anti-N-methyl-d-aspartate (NMDA) receptor encephalitis, only recently first described, is an increasingly well-recognized inflammatory encephalitis that is seen in children and adults. An 11-year old girl admitted to the psychiatry ward with a presentation of acute psychosis was diagnosed with NMDA receptor encephalitis following neurology referral and was treated accordingly. This case highlights psychiatric manifestations in encephalitis and the need for the psychiatrist to have high index of suspicion when atypical symptoms (e...

Efforts to clinically diagnose cases having dementia with Lewy bodies (DLB) identify those with a characteristic clinical syndrome (probable DLB) at the expense of missing an equal, if not greater, number of cases who have atypical presentations thought to be associated with coexisting Alzheimer pathologies. This article argues that further efforts should now be made to characterize this atypical group that constitutes cases previously identified postmortem as the Lewy body variant of Alzheimer disease (AD) or as AD with Lewy bodies...

Progressive supranuclear palsy (PSP) is a low-prevalence atypical parkinsonism with underlying 4R-tauopathy and a growing number of clinical phenotypes, making its differential diagnosis from other conditions such as Parkinson's disease (PD) and corticobasal degeneration particularly challenging (1,2). Neuronal intermediate filament inclusion disease (NIFID), a sporadic alpha-internexin and fused-in-sarcoma (FUS) proteinopathy, is an even rarer condition with few cases published worldwide. It is most often diagnosed at autopsy, again due to a remarkable clinical heterogeneity ranging from young-onset frontotemporal dementia to PSP-lookalike parkinsonism, among other phenotypes (3-6)...

BACKGROUND: In 2011, the U.S. Department of Health and Human Services sent a letter to state Medicaid directors explaining the need for oversight of psychiatric prescriptions for children with mental health disorders. The National Committee for Quality Alliance proposed 3 quality measures for rating managed care organizations (MCOs) that involve use of second-generation or atypical antipsychotics in children. In order to ensure appropriate use and to effectively manage the use of second-generation antipsychotics in children, MCOs need to better understand the factors that influence medication treatment decisions for children...

Systemic lupus erythematosus (SLE) may involve the nervous system but there are no specific biomarkers of neuroSLE. Limbic encephalitis has been rarely associated with SLE. We present a case of a 22-year-old black woman where typical SLE psychosis evolved to an encephalopathy with atypical features, normal MRI, electroencephalogram slowing and frontal and occipito-temporal hypometabolism on fluorodeoxyglucose positron emission tomography (FDG PET).Memory deficits, bizarre behaviour, psychosis, neuromyotonia and movement disorders have been described in autoimmune central nervous system disorders and associated with specific antibodies...

The category of an "Early Psychosis" refers to a common medical classification. It is an essential part of the knowledge constituting mental health even as it represents a normative category subsuming a set of peculiarities in human behaviour, speech, emotional expression, and mental states that together can be described as a mental disorder. Numerous publications since the 1990s have rendered the "Early Psychosis" into a focus of standardised research, prevention and therapy procedures, while earlier medical practices remained unknown...

OBJECTIVE: Although a minority of persons with schizophrenia (SCZ) commits violent acts, SCZ remains a risk factor for violence. Here, we present a broad overview of evidence-based treatments for violence in SCZ, including biological and psychosocial interventions. METHOD: We conducted MEDLINE and PsychINFO literature searches to retrieve articles relating to treatments for violent, hostile, or aggressive behaviours in SCZ. RESULTS: Clozapine shows the strongest evidence for treating the acute violence of SCZ...

Psychosis of epilepsy (POE) is a term applied to a group of psychotic disorders with a distinct phenomenology in which potential etiopathogenic mechanisms are believed to be closely related to a seizure disorder. POE can present as interictal psychotic episodes, which may often differ semiologically from primary schizophrenic disorder. They may present as ictal or postictal psychotic episodes and may be the expression of an iatrogenic process to pharmacologic and/or surgical interventions.Epilepsy and POE have a complex and bidirectional relation, as not only are patients with epilepsy at greater risk of developing a psychotic disorder, but patients with a primary psychotic disorder are also at greater risk of developing epilepsy...

OBJECTIVES: Clozapine is an atypical antipsychotic primarily prescribed for treatment-resistant schizophrenia. We tested the specific effect of clozapine versus other drug treatments on whole-blood gene expression in a sample of patients with psychosis from the UK. METHODS: A total of 186 baseline whole-blood samples from individuals receiving treatment for established psychosis were analysed for gene expression on Illumina HumanHT-12.v4 BeadChips. After standard quality-control procedures, 152 samples remained, including 55 from individuals receiving clozapine...

BACKGROUND: Central nervous system (CNS) germ cell tumors account for 3 % of all pediatric brain tumors in the USA. Presenting symptoms are typically location based with pineal tumors presenting with obstructive hydrocephalus and suprasellar tumors with hypothalamic/pituitary dysfunction and ophthalmologic abnormalities. Psychiatric manifestations such as psychosis and behavioral changes are atypical presentations of CNS germ cell tumors, with only 11 previously reported cases. METHODS: This is a retrospective case series describing patients with CNS germ cell tumors with an atypical presentation including psychiatric manifestations...

Background. No consensus between guidelines exists regarding neuroimaging in first-episode psychosis. The purpose of this study is to assess anomalies found in structural neuroimaging exams (brain computed tomography (CT) and magnetic resonance imaging (MRI)) in the initial medical work-up of patients presenting first-episode psychosis. Methods. The study subjects were 32 patients aged 18-48 years (mean age: 29.6 years), consecutively admitted with first-episode psychosis diagnosis. Socio-demographic and clinical data and neuroimaging exams (CT and MRI) were retrospectively studied...

For clinical management of different forms of psychosis, both classical and atypical anti-psychotic drugs (APDs) are available. These drugs are widely prescribed, even during pregnancy considering their minimal extra-pyramidal side effects and teratogenic potential compared to classical APDs. Among AAPDs, risperidone (RIS) is a first-line drug of choice by physicians. The molecular weight of RIS is 410.49 g/mol; hence, it can easily cross the placental barrier and enter the foetal bloodstream. It is not known whether or not AAPDs like RIS may affect the developing placenta and foetus adversely...
