Importance: There is concern about potentially causal effects of tobacco use on psychosis, but epidemiological studies have been less robust in attempts to minimize effects of confounding than studies of cannabis use have been. Objectives: To examine the association of patterns of cigarette and cannabis use with preceding and subsequent psychotic experiences, and to compare effects of confounding across these patterns. Design, Setting, and Participants: This cohort study used data from the Avon Longitudinal Study of Parents and Children, which initially consisted of 14 062 children...

BACKGROUND: Schizophrenia is a chronic psychiatric disorder that generally begins in late adolescence or early adulthood. This early onset is often linked with a devastating lifelong impact on both the social network and work capacities of the affected subjects. Beginning in the mid-1990s, several sets of diagnostic criteria aiming to identify "high-risk" patients were developed and applied in clinical studies. Short-term rates of onset of psychosis in this subgroup of subjects ranged from 20% to 40%...

Mutations in the stress granule protein T-cell restricted intracellular antigen 1 (TIA1) were recently shown to cause amyotrophic lateral sclerosis (ALS) with or without frontotemporal dementia (FTD). Here, we provide detailed clinical and neuropathological descriptions of nine cases with TIA1 mutations, together with comparisons to sporadic ALS (sALS) and ALS due to repeat expansions in C9orf72 (C9orf72+). All nine patients with confirmed mutations in TIA1 were female. The clinical phenotype was heterogeneous with a range in the age at onset from late twenties to the eighth decade (mean = 60 years) and disease duration from one to 6 years (mean = 3 years)...

A substantial subset of people with psychotic disorders are first diagnosed in old age, yet little is known about the epidemiology of very late-onset schizophrenia-like psychosis. We investigated the incidence of affective and non-affective psychotic disorders in those aged 65 and above, and examined variation related to potential risk factors via systematic literature review. We searched PubMed, PsychInfo, Web of Science and bibliographies and directly contacted authors to obtain citations published between 1960 and 2016 containing (derivable) incidence data...

BACKGROUND: The delusional misidentification syndromes (DMS) include a myriad of discrete but related syndromes, which have wide spectrum anomalies of familiarity. Several misidentification syndromes have been described in the psychiatric literature, the most common of these delusions are: the Capgras syndrome; the Fregoli syndrome; the syndrome of inter-metamorphosis; reduplicative paramnesia; and environmental reduplication. CASE PRESENTATION: The reported case highlights the emergence of late onset first episode psychosis in a Middle Eastern 65-year-old female who has no previous psychiatric history...

BACKGROUND: This study looks at key risk factors in patients with schizophrenia to identify trends according to age of onset, comparing presentations prior to 26years (youth onset), between 26 and 40years (middle onset), and after 40years of age (late onset). METHODS: The early psychosis program at St Vincent's Hospital Melbourne treats patients presenting in the early stages of psychosis between 16 and 65years of age. A database was developed to capture key risk factors in all patients with an eventual diagnosis of schizophrenia (n=225)...

The prevalence of psychotic disorders in individuals with 22q11.2 Deletion Syndrome (22q11DS) reaches 25-35% in young adulthood and may provide a neurogenetic model for clinical risk of psychotic disorders in the general population. This review focuses on prospective longitudinal studies in 22q11DS, which capture fluctuations in psychosis symptoms over time and may provide insights into potential demographic, clinical, cognitive, and neuroimaging predictors of psychosis-spectrum outcomes in the general population...

Psychosis symptoms (delusions and hallucinations) are multifactorial in origin and, in later life, occur in the context of schizophrenia, delirium, dementia, delusional and schizophrenia-like disorders, mood disorders, and alcohol or substance abuse. The current article provides a clinical overview of very late-onset (after age 60) schizophrenia-like psychosis (VLOSLP), summarizing the literature on treatment options and reflecting on the role of psychiatric-mental health nurses (PMHNs). Increased awareness of the clinical presentation, key features, and evidence-based treatment options will assist PMHNs to confidently recognize this often under-diagnosed disorder and adopt a more assertive role in terms of engagement and follow up...

INTRODUCTION: Psychosis is one of the common non-motor symptoms of PD, which substantially worsens the quality of life. Hence, it is important to identify factors that are associated with early onset of psychosis in PD. In order to identify those factors, the current study aims to compare various demographic and clinical features of PD patients with early and late onset psychosis. METHODOLOGY: In this prospective case-control study, 51 consecutive patients with PD having psychosis (PDP) were recruited...

BACKGROUND: The echinocandins have shown anti-Pneumocystis jiroveci activity in nonhuman animal models; however, the corresponding human clinical experience has been rarely reported. We report a clinical picture of P jiroveci pneumonia (PJP) and determine the effects of concomitant therapy with echinocandins and trimethoprim (TMP)-sulfamethoxazole (SMZ). METHODS: We investigated a retrospective case series of heart transplantation (HT) recipients with PJP from July 1988 to December 2015...

Argyrophilic grain disease (AGD) is a common four-repeat tauopathy in elderly people. While dementia is a major clinical picture of AGD, recent studies support the possibility that AGD may be a pathological base in some patients with mild cognitive impairment, late-onset psychosis, bipolar disorder and depression. AGD often coexists with various other degenerative changes. The frequency of AGD in progressive supranuclear palsy (PSP) cases was reported to range from 18.8% to 80%. The frequency of AGD in corticobasal degeneration (CBD) cases tends to be higher than that in PSP cases, ranging from 41...

OBJECTIVE: The current review discusses neuropsychological profiles and the longitudinal course of cognitive dysfunction in Late Onset Schizophrenia (LOS) and Very-late-onset schizophrenia-like psychosis (VLOSLP), and attempts to clarify its neurobiological underpinnings. METHOD: A systematic literature search resulted in 29 publications describing original research on the neuropsychology of LOS/VLOSLP and 46 studies focussing on neurobiology. RESULTS: Although mildly progressive cognitive impairment is usually present, only a subgroup of LOS/VLOSLP develops dementia during a 10-year follow-up succeeding the onset of psychosis...

OBJECTIVE: Antipsychotic drug sensitivity in very late-onset schizophrenia-like psychosis (VLOSLP) is well documented, but poorly understood. This study aimed to investigate blood drug concentration, D2/3 receptor occupancy and outcome in VLOSLP during open amisulpride prescribing, and compare this with Alzheimer's disease (AD). METHODS: Blood drug concentration, prolactin, symptoms and extrapyramidal side-effects (EPS) were serially assessed during dose titration...

BACKGROUND: Progression of dementia is often associated with the emergence of neuropsychiatric symptoms (NPS), though there is recent evidence that NPS may occur in prodromal dementia (PrD) and impact clinical course. Mood and anxiety symptoms are the NPS that tend to occur most frequently in PrD and thus have been most extensively studied. Comparatively, there has been little focus on psychotic symptoms in PrD. METHODS: The authors review the existing literature on psychosis in PrD, including the functional psychosis of early and late onset, with a focus on epidemiology, phenomenology, and clinical course and treatment considerations...

This work aimed to deepen the lately acquired knowledge about parenteral nanoemulsions as carriers for brain delivery of risperidone, a poorly water-soluble antipsychotic drug, through establishing the prospective relationship between their physicochemical, pharmacokinetic, biodistribution, and behavioral performances. For this purpose, two optimized risperidone-loaded nanoemulsions, stabilized by lecithin or lecithin/polysorbate 80 mixture, and costabilized by sodium oleate, were produced by high-pressure homogenization...

BACKGROUND: Dementia is generally characterized by cognitive impairment that can be accompanied by psychotic symptoms; for example, visual hallucinations are a core feature of dementia with Lewy bodies, and delusions are often seen in Alzheimer's disease. However, for behavioral variant of frontotemporal dementia (bvFTD), studies on the broad spectrum of psychotic symptoms are still lacking. The aim of this study was to systematically and prospectively subtype the wide spectrum of psychotic symptoms in probable and definite bvFTD...

The C9orf72 mutation was identified as the most frequent genetic cause of frontotemporal dementia (FTD). In light of multiple reports of predominant psychiatric presentations of FTD secondary to C9orf72 mutation, the American Neuropsychiatric Association Committee on Research reviewed all studies on psychiatric aspects of this mutation to identify clinically relevant features for diagnosis. The most common psychiatric presentation is psychosis (21%-56%), with delusions, and/or multimodal hallucinations. Other presentations include late-onset mania and depression with cognitive impairment or catatonia...
