New wine in old bottle: late-life psychosis

Clinical outcomes and treatment patterns of older adults with dementia-related psychosis by dementia type in the United States

Background

Little is known about the incidence of clinical events and treatment patterns among older adults with dementia-related psychosis. Given that dementia-related psychosis comprises various dementia types, this study describes the incidence of clinical events and treatment patterns by dementia type after patients with dementia are diagnosed with psychosis.

Methods

Adults aged ≥ 65 years with dementia and newly diagnosed with psychosis were identified in US Medicare claims during 2013–2018. Baseline characteristics were evaluated at the time of the psychosis diagnosis. After the initial psychosis diagnosis, incidence rates (IRs) of clinical events (e.g., falls/fractures, infections, healthcare utilization), mortality, and patterns of antipsychotic treatment were described for each dementia type (Alzheimer’s disease [AD], Parkinson’s disease dementia [PDD], dementia with Lewy bodies [DLB], frontotemporal dementia [FTD], vascular dementia [VD], and unspecified dementia). Daily mean cumulative counts were estimated to describe the incidence of recurrent events over time. Mortality was described using Kaplan–Meier survival curves.

Results

We identified 484,520 patients with dementia-related psychosis: mean age, 84 years (standard deviation, 7.8); female, 66%. At the time of psychosis diagnosis, the most prevalent type of dementia was unspecified dementia (56%), followed by AD (31%), VD (12%), PDD (10%), DLB (3%), and FTD (< 1%), and most patients had scores indicating severe illness on the Charlson Comorbidity Index (71%) and frailty index (62%). Across all dementia types, IRs (per 100 person-years) were high for emergency department visits, oral anti-infective use, and urinary tract infections after the initial psychosis diagnosis. Patients with DLB had the highest incidence of most clinical outcomes. After 1 year of follow-up, the cumulative probability of death was about 30% for all dementia types, and after 5 years, was about 80% among patients with DLB, VD, AD, or PDD and about 60%-65% among patients with FTD or unspecified dementia.

Conclusions

Patients with dementia-related psychosis had a high burden of comorbidities, frailty, emergency department visits, infections, and death. Specifically, after DRP diagnosis, patients with DLB and VD had the highest burden of clinical events of interest.

Neuropsychiatric symptoms and caregiver relationship quality for older Mexican Americans

OBJECTIVES

Caregivers play a key role in supporting older Mexican Americans, who are less likely to enter nursing facilities than other racial/ethnic groups in the US. However, there is little research on how Neuropsychiatric symptoms (NPS) affect relationship quality between caregivers and care recipients.

METHOD

Using data from the 2015 wave of the Hispanic Established Populations for Epidemiologic Studies of the Elderly (H-EPESE) (n = 416) study of older (age 85+) Mexican Americans, we examined relationship quality and NPS with ordered logistic regression. Relationship quality was measured using positive (enjoyment, appreciation) and negative (nerves, argue) assessments. NPS were categorized into hyperactivity, affective, and psychosis symptoms.

RESULTS

Hyperactivity symptoms were associated with appreciation, arguing, and nerves. Psychosis symptoms were associated with arguing and nerves. Spousal caregivers were more likely to report arguing and nerves and less likely to report feeling appreciated. Enjoyment assessments were not associated with NPS.

CONCLUSION

Relationship quality is related to behavioral changes in late life. Mexican American caregivers negatively evaluate their relationships, not in response to care tasks per se, but when the older person exhibits behavioral problems. The relationship between NPS and negative relationship assessments may be due to unanticipated behavior changes in late life and stigma around psychiatric symptomatology.

Clinical Approaches to Late-Onset Psychosis

Psychosis can include schizophrenia, mood disorders with psychotic features, delusional disorder, active delirium, and neurodegenerative disorders accompanied by various psychotic symptoms. Late-onset psychosis requires careful intervention due to the greater associated risks of secondary psychosis; higher morbidity and mortality rates than early-onset psychosis; and complicated treatment considerations due to the higher incidence of adverse effects, even with the black box warning against antipsychotics. Pharmacological treatment, including antipsychotics, should be carefully initiated with the lowest dosage for short-term efficacy and monitoring of adverse side effects. Further research involving larger samples, more trials with different countries working in consortia, and unified operational definitions for diagnosis will help elaborate the clinical characteristics of late-onset psychosis and lead to the development of treatment approaches.

Psychotropic medication use patterns in home-based primary care: A scoping review

Introduction

Up to a third of patients seen by home-based primary care (HBPC) providers suffer from mental health problems. These conditions tend to be underrecognized and undertreated for patients receiving HBPC. The purpose of this scoping review is to evaluate current psychotropic use patterns for patients receiving HBPC services.

Methods

The following databases were searched for articles reporting on studies conducted in HBPC settings that identified patterns of psychotropic medication prescription and use: Ovid/MEDLINE, Cochrane Library, Embase, Scopus, Web of Science, CINAHL, and PsycInfo. Studies that only reported on patients in hospice, rehabilitation, or long-term care facilities were excluded as were drug trials, opinion pieces, case studies, case series, meeting abstracts, and other reviews.

Results

Of 4542 articles initially identified, 74 were selected for full text screening. Of these, only 2 met full criteria and were included in the data extraction and analysis. In 1 study, 41.7% patients enrolled were prescribed an antidepressant, 21.5% were prescribed an antipsychotic (12.7% prescribed both), and 5% to 7% of patients were prescribed benzodiazepines/hypnotics. In the other study, 9% of patients were prescribed an antipsychotic, and 7% were prescribed a benzodiazepine.

Discussion

There are extremely limited data on psychotropic prescribing patterns in HBPC in published studies. Because a significant number of HBPC patients suffer from mental health conditions in addition to other chronic illnesses, treatment can be complex. More studies are needed on current psychotropic prescribing trends to help determine what type of interventions are needed to promote patient safety in this setting.

An Australian study of delusional disorder in late life

OBJECTIVES

There is a paucity of available research to guide clinical practice in delusional disorder (DD), particularly in late life. This study aimed to evaluate antipsychotic use and treatment outcomes in patients with DD aged 65 years and older. Secondarily, we sought to examine associated clinical features and socio-demographic variables.

DESIGN AND SETTING

This descriptive study reviewed all consecutive cases of DD referred to an Australian old age psychiatry service over a 12-year period. Fifty-five patients were assessed in the inpatient and/or community setting, with data verified from a review of all individual medical records.

MEASUREMENTS

Data were collected with respect to antipsychotic use, outcomes, and clinical features. Socio-demographic variables of DD cases were compared to a non-matched comparison group (n=278) and an age and gender matched comparison group with a 1:1 ratio (n=55).

RESULTS

The predominant type of DD was persecutory (87%). Non-prominent hallucinations were experienced by 18%, and depressive symptoms occurred in 22%. There was a statistically significant association between having DD and social isolation (χ2= 11.04 (DF=1) p<0.001; McNemar's test p<0.001). Atypical antipsychotic medication was prescribed in 32 cases, with follow-up permitted in 51 of the 55 cases (mean duration 36.6 months). Sustained recovery occurred in 20%, and improvement in an additional 35% of the study sample. Four patients subsequently developed dementia, and two developed mild cognitive impairment.

CONCLUSIONS

Clinical improvement, including sustained recovery, occurred in more than half of those with late life DD. The majority of those who improved (96%) received atypical antipsychotics.

Gender, mental health and ageing

This article presents a broad narrative review of the epidemiological evidence on how and why the mental health of older adults varies by gender. We draw upon international research literatures spanning gerontology and population mental health, as well as major reports from global health agencies. Compared with older men, older women are more likely to experience common mental disorders such as depression and anxiety, although the gender gap is smaller than it is at younger ages. In contrast, the mortality-related impacts of poor mental health, including suicide, are more severe for older men. These gendered patterns vary by country and other social contexts. Factors proposed to account for these findings include cultural and social norms, differentiation of gender roles, disadvantage and (dis)empowerment across the life course, and the coping styles of older men. However, little research has explicitly tested these explanations. Research to date has overwhelmingly focused on identifying differences in the mental health of older men and women. Notably, most studies have been restricted to binary comparisons, lacking the data to disentangle sex and gender dynamics, and few studies have examined the mental health of minority gendered adults in later life. Finally, there remains a need for high-quality population-based research into the mental health of those aged over 80 that includes coverage of people living in residential aged care settings.

Late-onset psychosis and very-late-onset-schizophrenia-like-psychosis: an updated systematic review

Psychotic disorders have long been known to be a condition that peaks during adolescence and early adulthood. A considerable proportion of patients have their first onset at or after the age of 40, but little is known about this population. The current systematic review examined the clinical presentation of late-onset psychosis (LOP) and very-late-onset-schizophrenia-like psychosis (VLOSLP) with focus on their psychopathological, neuropsychological, neurobiological, psychosocial and psychological correlates. A systematic search of studies published from 2000 to 2019 from Cochrane Library, Pubmed, Medline, Embase, PsycINFO, and Scopus yielded 27 original studies that were included in this review. Results revealed there is a dearth of empirical research on the conditions in the current literature and inconsistencies in the findings reported may be associated with the lack of uniformity in the definitions for LOP and VLOSLP. Future research on the topic shall (i) specify the onset age criteria for LOP and VLOSLP; (ii) study the conditions independently; (iii) involve a larger sample size, and iv) account for potential confounding variables. A comprehensive evaluation of the risks and benefits of pharmacological treatment may also be needed.

[Diseases of the schizophrenia spectrum disorder in old age : Diagnostic and therapeutic challenges]

BACKGROUND

The number of people with diseases of the schizophrenia spectrum in old age will increase significantly in the coming years. In the literature the topics of schizophrenia and delusional disorders in older and old people are inadequately represented.

AIM

This article gives an overview of the most important diagnostic and differential diagnostic characteristics. Another important aspect is the pharmacological and non-pharmacological treatment options in old age.

MATERIAL AND METHODS

The S3 guidelines of the German Association for Psychiatry, Psychotherapy and Psychosomatics (DGPPN) from 2006, the guidelines of the World Federation of Societies of Biological Psychiatry (WFSBP) from 2012, 2013, 2015 and the consensus statement of the Austrian Association for Neuro-Psychopharmacology and Biological Psychiatry (ÖGPB) from 2016 formed the basic literature for this review. In addition, a targeted search in the databases PubMed, PubPsych and Cochrane Library as well as in German Journals, such as DerNervenarzt, Neuropsychiatrie, Psychiatrische Praxis and Zeitschrift für Gerontologie und Geriatrie concerning the keywords schizophrenia, delusional disorder, diagnostics, therapy and older people was carried out.

RESULTS

Besides aspects on epidemiology, clinical manifestation, diagnostics, differential diagnostics and course of the illness, pharmacological and non-pharmacological treatment options are presented.

CONCLUSION/DISCUSSION

In clinical practice a clear diagnostic assignment is often a challenge in older and very old people with psychotic symptoms, The necessary pharmacological treatment is available but is limited by tolerability, comorbidities and polypharmacy. Non-pharmacological treatment options have hardly been investigated.

[Schizophrenia spectrum disorders in elderly patients : Analysis of reasons for admission to a department of geriatric psychiatry]

OBJECTIVE

The aim of this study was to analyze the possible reasons for acute admission to a department for geriatric psychiatry. The reasons for hospitalization, the psychiatric and somatic comorbidities of the patients over 65 years old with schizophrenia, schizoaffective disorder and delusional disorder were examined to identify patterns and risk profiles.

MATERIAL AND METHODS

A retrospective analysis was carried out using paper and electronic patient records of a department of acute care for geriatric psychiatry and psychotherapy. During the assessment period 206 successive patients over 65 years old were included in the study. The patient cohort included 64 patients with schizophrenia according to the international classification of diseases 10 (ICD-10, category F20), 78 patients with persistent delusional disorder (ICD-10, F22) and 64 patients with schizoaffective disorder (ICD-10, F25).

RESULTS

The reason for admission for one third of the patients in all three groups was aggressive behavior, whereas delusions and hallucinations were more frequent in the groups of F20 and F22 patients than in patients with schizoaffective disorders (F25). Somatic comorbidities were seen significantly more often in the group of F22 patients than in the other two groups.

CONCLUSION

Acute admission was essentially due to acute psychiatric symptoms. Additional somatic comorbidities and psychosocial influencing factors played only a minor role in this study. The patients examined in this study constituted a special group within the acute treatment of inpatient psychiatry because they showed distinctive psychopathological productive symptoms but were relatively healthy from a somatic point of view. Patients with the diagnosis of schizophrenia (F20) or schizoaffective disorder (F25) were significantly different from patients classified into the group of delusional disorders (F22).

[Clinical diagnosis and drug therapy of elderly patients with schizophrenia : A restrospective analysis of data in a department of old age psychiatry]

BACKGROUND

The objective of this study was to survey the consistency of the clinical diagnostics and the psychopharmacological treatment of schizophrenia and delusional disorders suffered by older persons. A further aspect was to record significant clinical differences and also similarities between the patient groups in care, matching with the criteria of ICD 10 for schizophrenia (F20), persistent delusional disorders (F22) and schizoaffective disorder (F25).

METHODS

Retrospective analysis with reference to the manually and electronically recorded patient medical records of an acute case care ward for geriatric psychiatry and psychotherapy.

RESULTS

During the assessment period 210 patients over the age of 65 years were included consecutively in the study (F20 - 64 patients, F22 - 78 patients, F25 - 64 patients, 4 patients died). Ignoring the fact that many of the patients were admitted without a diagnosis, the diagnostic classification of the referring doctor, above all those made by general practitioners, proved to be very consistent for the groups F20 and F25. In the group F22 diagnoses, however, up to almost one half of the referred patients were incorrectly admitted with an F20 diagnosis. The patients included in group F22 formed a heterogeneous group, or a melting pot for various sub-groups, with the common shared characteristic of being comprised of persons suffering from a delusional disorder. These differed from the other two groups in the following attributes: the patients were either older or very old persons, they were mostly receiving inpatient treatment for the first time and subsequently had fewer re-admissions. They also suffered more frequently from both psychiatric and somatic comorbidities; furthermore they included elderly people who had suffered from learning deficiencies or borderline intellectual deficiencies throughout their earlier lives. The patients in groups F20 and F25 differed primarily only in terms of their psychiatric medication, with significantly more mood stabilizer prescribed in the F25 group. Patients in all three groups frequently received tranquilisers during the day and sedatives in the evening, atypical antipsychotics were prescribed in the great majority of cases.

CONCLUSION

The referral diagnoses of patients suffering from many years of schizophrenic type illnesses were largely in compliance with the diagnostic criteria, a much more difficult issue for the referring doctors was the allocation of patients with a first occurrence of delusional symptoms. Those patients who were allocated to the diagnostic group schizophrenia differed significantly from patients from the group with delusional disorders.

Psychosis in Later Life: A Review and Update

Psychosis is relatively common in later life and can present in a wide variety of contexts, including early-onset and late-onset schizophrenia, delusional disorder, mood disorders, and various dementias. It can also occur as the result of numerous medical and neurological diseases and from the use of certain medications. Although identifying the cause of psychosis in older patients can be challenging, the unique clinical features associated with the different disorders can help in making the diagnosis. Accurate diagnosis of psychosis in older populations is essential, as its treatment varies depending on the context in which it appears. Despite the safety concerns regarding the use of antipsychotics in older patients, certain pharmacological treatments appear to be both efficacious and reasonably safe in treating psychosis in older populations. Additionally, although research is limited, numerous psychosocial therapies appear promising. This review summarizes the literature on the epidemiology, clinical characteristics, neuroimaging, and treatment of psychosis in later life, and serves as an update to past reviews on this topic.

Slow Progression of Cognitive Dysfunction of Alzheimer's Disease in Sexagenarian Women with Schizophrenia

Although both schizophrenia (SCZ) and Alzheimer's disease (AD) are among the most common psychiatric diseases, the interaction of these two is not well-understood. We investigated three women with SCZ who developed AD in their 60s. The patients presented with cognitive dysfunction such as loss of recent memory, which was confirmed by both clinical observations and neuropsychological tests. Their magnetic resonance and functional imaging findings were consistent with AD. Their brain atrophy advanced significantly during a 6-year observation period. However, their global cognitive function did not deteriorate significantly during this period. Although the cognitive reserve model might account for this discrepancy, our results suggest some interactions between the neuropathology of SCZ and AD and warrant further research.

Comparative study of clinical and neuropsychological characteristics between early-, late and very-late-onset schizophrenia-spectrum disorders

OBJECTIVE

To compare the clinical and neurocognitive profile of early-onset (EOP, <40 years), late-onset (LOP, 40-59 years) and very-late-onset (VLOP, ≥60 years) psychosis.

DESIGN

Cross-sectional observational study.

SETTING

Secondary, tertiary, and community mental health care.

PARTICIPANTS

Patients with a DSM-IV diagnosis of non-affective psychotic disorder were included from two complementary studies (GROUP and PSITE) on genetic and environmental risk factors of psychosis in the Netherlands and Belgium.

MEASUREMENTS

Main outcome measures were the severity of positive and negative symptoms, quality of life, and age-corrected scores on measures of general intelligence, verbal memory, attention, and executive function. One-year follow-up data were used to validate diagnoses and exclude participants with possible or probable dementia.

RESULTS

286 EOP (85%), 24 LOP (7%) and 28 VLOP (8%) participated. VLOP patients reported significantly more positive symptoms than EOP patients. Age-at-onset groups had similar age-corrected scores on IQ, verbal memory, attention and executive functions. A significantly better performance was found in VLOP compared with LOP on the CAMCOG total score, though scores were still within the normal range. After controlling for possible confounding, however, VLOP differed significantly on an attention accuracy task compared with LOP patients. Re-entering data for probable dementia patients (N = 4) did change the results regarding cognition outcomes.

CONCLUSIONS

VLOP patients show more positive symptoms but do not appear to differ on neuropsychological tests from EOP and LOP when age is controlled for. This questions the idea that VLOP is the expression of underlying neurodegeneration.

Late-life psychosis: diagnosis and treatment

Psychosis is one of the most common conditions in later life with a lifetime risk of 23 %. Despite its high prevalence, late-onset psychosis remains a diagnostic and treatment dilemma. There are no reliable pathognomonic signs to distinguish primary or secondary psychosis. Primary psychosis is a diagnosis of exclusion and the clinician must rule out secondary causes. Approximately 60 % of older patients with newly incident psychosis have a secondary psychosis. In this article, we review current, evidence-based diagnostic and treatment approaches for this heterogeneous condition, emphasizing a thorough evaluation for the "six d's" of late-life psychosis (delirium, disease, drugs dementia, depression, delusions). Treatment is geared towards the specific cause of psychosis and tailored based on comorbid conditions. Frequently, environmental and psychosocial interventions are first-line treatments with the judicious use of pharmacotherapy as needed. There is an enormous gap between the prevalence of psychotic disorders in older adults and the availability of evidence-based treatment. The dramatic growth in the elderly population over the first half of this century creates a compelling need to address this gap.
