Barriers to Treatment of Hallucinations and Delusions in People With Dementia Residing in Long-Term Care.

Importance: Most people with dementia will experience neuropsychiatric symptoms, including psychosis characterized by hallucinations and delusions. Across dementia subtypes, hallucinations and delusions are common, though their prevalence and presentation may vary. These symptoms have been associated with worse outcomes compared with dementia alone, including accelerated functional decline and mortality. Many people with dementia reside in long-term care facilities, and identification and management of hallucinations and delusions in this setting are critical.Observations: For residents in long-term care facilities, the following factors can hinder management of hallucinations and delusions related to dementia: (1) delayed recognition of symptoms; (2) reluctance of staff and family members to acknowledge psychiatric issues; (3) lack of approved pharmacotherapies to treat hallucinations and delusions associated with dementia-related psychosis; and (4) regulatory and institutional guidelines, including the long-term care regulatory guidelines established by the Centers for Medicare and Medicaid Services and the 5-star rating system.Conclusions and Relevance: Barriers to the treatment of hallucinations and delusions in patients with dementia in the long-term care setting are myriad and complex. Early diagnosis of dementia-related psychosis and new treatment options for managing hallucinations and delusions are needed to improve care of this patient population.

Violence and Suicide Risk Assessment in Youth with Psychotic Disorders: Practical Considerations for Community Clinicians.

Psychosis is a unique and significant risk factor associated with violent and suicidal behavior and warrants special consideration. This article presents a careful review of the literature on violence risk and psychosis and suicide risk and psychosis as it pertains to youth or those who have been newly diagnosed with or are at high risk for psychotic disorders. Each topic is covered in reference to general considerations and specific psychotic symptoms (eg, hallucinations, delusions, paranoia). The reader can refer to practical boxes to assist in identifying relevant risk factors and examples of questions to ask the patient and family.

Functional Behavioral Assessment-based interventions on adults' delusions, hallucinations and disorganized speech: A single case meta-analysis.

The Functional Behavioral Assessment (FBA) approach involves the use of single-case designs (SCD) to study the problem behavior-environment contingencies and conduct interventions that consider this functional relationship. Although this approach has been considered an evidence-based practice (EBP) for the treatment of several psychological problems, no meta-analytic studies of FBA-based interventions on delusions, hallucinations and disorganized speech -commonly operationalized as "atypical vocalizations"- have been carried out. Therefore, the purpose of this study was to review and synthesize the results of FBA-based interventions on adults' atypical vocalizations. We conducted a systematic review and a multi-level meta-analysis of these interventions, using a recently developed effect size estimator for SCD studies (i.e., log response ratio). All the studies that met our eligibility criteria provided evidence supporting the effectiveness of FBA-based interventions on atypical vocalizations, with an overall average effect size of a 72% reduction. Both the publication year and the methodological quality were found to be significant moderators. Despite some methodological limitations, we can conclude that FBA-based interventions are effective to reduce atypical vocalizations. The implications of these results could be of interest for the mental health community.

Sociodemographic and clinical correlates of psychotic symptoms in the general population: Findings from the MHGP survey.

BACKGROUND: We aimed to explore the sociodemographic and psychiatric correlates of psychotic symptoms in a large general population sample. METHODS: The French Mental Health in the General Population cross-sectional survey interviewed 38,694 individuals using the Mini International Neuropsychiatric Interview. We looked for associations between the presence of lifetime psychotic symptoms, sociodemographic characteristics (including migrant status over three generations) and clinical characteristics. We then looked for associations regarding only hallucinations, delusional symptoms, and the co-occurrence of both hallucinations and delusional symptoms. To test the psychosis continuum hypothesis, associations with sociodemographic characteristics were compared with the characterized psychotic disorders' associations. RESULTS: We found that 22.3% of the population declared psychotic symptoms without psychotic disorders, including 5.7% who declared hallucinations, 20.5% delusional symptoms, 4.0% both hallucinations and delusional symptoms, and 2.8% characterized psychotic disorders. The presence of psychotic symptoms was associated with young age, migrant status (over three generations), secondary education level, low-income level and never-married and separated marital status. Hallucinations, delusional symptoms and the co-occurrence of both hallucinations and delusional symptoms showed the same correlates, and hallucinations were also associated with elementary education level. Characterized psychotic disorders showed the same correlates. Concerning clinical outcomes, the presence of psychotic symptoms, hallucinations and delusional symptoms was associated with all non-psychotic disorders, i.e., bipolar, depressive, alcohol use, generalized anxiety, social phobia, panic and post-traumatic stress disorders and dysthymia (except dysthymia, which was not associated with hallucinations). CONCLUSIONS: Our results indicate that psychotic symptoms are associated with broad psychopathologies and support the continuum model of psychosis.

Distress Associated with Dementia-Related Psychosis and Agitation in Relation to Healthcare Utilization and Costs.

OBJECTIVES: Explore the relationship between behavioral and psychological symptoms of dementia (BPSD; specifically, delusions, hallucinations, and agitation/aggression) and associated caregiver distress with emergency department (ED) utilization, inpatient hospitalization, and expenditures for direct medical care. DESIGN/SETTING/PARTICIPANTS: Retrospective cross-sectional cohort of participants with dementia (N = 332) and informants from the Aging, Demographics, and Memory Study, a nationally representative survey of U.S. adults >70 years old. MEASUREMENTS: BPSD of interest and associated informant distress (trichotomized as none/low/high) were assessed using the Neuropsychiatric Inventory (NPI). Outcomes were determined from one year of Medicare claims and examined according to presence of BPSD and associated informant distress, adjusting for participant demographics, dementia severity, and comorbidity. RESULTS: Fifty-eight (15%) participants with dementia had clinically significant delusions, hallucinations, or agitation/aggression. ED visits, inpatient admissions, and costs were not significantly higher among the group with significant BPSD. In fully adjusted models, a high level of informant distress was associated with all outcomes: ED visit incident rate ratio (IRR) 3.03 (95% CI: 1.98-4.63; p < 0.001), hospitalization IRR 2.78 (95% CI: 1.73-4.46; p < 0.001), and relative cost ratio 2.00 (95% CI: 1.12-3.59; p = 0.02). CONCLUSIONS: A high level of informant distress related to participant BPSD, rather than the symptoms themselves, was associated with increased healthcare utilization and costs. Effectively identifying, educating, and supporting distressed caregivers may help reduce excess healthcare utilization for the growing number of older adults with dementia.

Characteristics, correlates, and assessment of psychosis in Parkinson disease without dementia.

INTRODUCTION: Considering that psychosis in Parkinson disease (PD) is associated with worse outcomes, including dementia, we aimed to study the characteristics, correlates, and assessment of PD psychosis in those without dementia. METHODS: 101 PD subjects without dementia (Montreal Cognitive Assessment ≥21/30) were recruited to participate in a study of neuropsychiatric symptoms in PD. This study included a baseline standard neurological exam and common PD symptom assessments. Using the Scale for the Assessment of Positive Symptoms (SAPS) and separate assessment of visual illusions and sense of presence, NINDS-NIMH criteria for PD psychosis were applied. RESULTS: Of the 33 (32.7%) PD subjects who met diagnostic criteria for psychosis in PD, visual illusions were most common (72.7%), followed by visual hallucinations (39.4%). Adjusted for presence of REM sleep behavior disorder (RBD) (p = 0.097), use of dopamine agonists (OR = 3.7, p = 0.012) and greater autonomic symptom burden (OR = 1.1 (per 1-unit change in score on SCOPA-AUT), p = 0.012) were associated with greater risk of psychosis. Use of dopamine agonists (OR = 5.0, p = 0.007), higher MDS-UPDRS Part II score (OR = 1.1, p = 0.010), and presence of RBD (OR = 4.8, p = 0.012) were independent predictors of visual hallucinations and visual illusions. MDS-UPDRS item 1.2 score ≥1 had highly correlated with the SAPS score (r = 0.65, p < 0.0001), but was 42% sensitive and 96% specific for identifying psychosis. CONCLUSION: This study confirms the association between dopamine agonists and psychosis in PD patients without dementia. The association of RBD, autonomic symptoms, and MDS-UPDRS Part II scores with psychosis underscore its link to brainstem dysfunction and greater PD motor symptom severity.

Neuropsychiatric symptoms in dementia may predict caregiver burden: a Sicilian exploratory study.

BACKGROUND: Behavioural and psychological symptoms of dementia are very common. They represent a main cause of burden and distress in caregivers and can lead to early institutionalization of patients. We aimed to find the most specific behavioural and psychological symptoms of dementia that can strongly affect the caregivers' burden. METHODS: Twenty-seven patients and their caregivers were enrolled in this study. All of the patients were affected by Alzheimer's, vascular, or frontotemporal dementia and were evaluated with the Neuropsychiatric Inventory and Mini-Mental State Examination. Caregivers were administered the Caregiver Burden Inventory. RESULTS: Apathy, depression, anxiety, and agitation were the most common symptoms and were found in up to 90% of the patients. We detected strong correlations between patient neuropsychiatric symptoms, (i.e. irritability, hallucinations, aberrant motor behavioural, depression, and agitation) and Caregiver Burden Inventory scores. Multiple regression analysis found hallucinations, irritability, and depression to be significant predictors of caregiver burden. Moreover, the Neuropsychiatric Inventory score was more closely related to caregiver burden than the Mini-Mental State Examination score. CONCLUSION: Our results revealed that demented patients' behavioural problems are related to the level of caregiver burden and distress. Further investigations are needed to differentiate the present findings among dementia subtypes and to better evaluate the effect of caregivers' personal characteristics on their own burden.

Are there sensitive time periods for dementia caregivers? The occurrence of behavioral and psychological symptoms in the early stages of dementia.

BACKGROUND: The behavioral and psychological symptoms associated with dementia (BPSD) can be burdensome to informal/family caregivers, negatively affecting mental health and expediting the institutionalization of patients. Because the dementia patient-caregiver relationship extends over long periods of time, it is useful to examine how BPSD impact caregiver depressive symptoms at varied stages of illness. The goal of this study was to assess the association of BPSD that occur during early stage dementia with subsequent caregiver depressive symptoms. METHODS: Patients were followed from the early stages of dementia every six months for up to 12 years or until death (n = 160). Caregiver symptoms were assessed on average 4.5 years following patient's early dementia behaviors. A generalized estimating equation (GEE) extension of the logistic regression model was used to determine the association between informal caregiver depressive symptoms and BPSD symptoms that occurred at the earliest stages dementia, including those persistent during the first year of dementia diagnosis. RESULTS: BPSD were common in early dementia. None of the individual symptoms observed during the first year of early stage dementia significantly impacted subsequent caregiver depressive symptoms. Only patient agitation/aggression was associated with subsequent caregiver depressive symptoms (OR = 1.76; 95% CI = 1.04-2.97) after controlling for concurrent BPSD, although not in fully adjusted models. CONCLUSIONS: Persistent agitation/aggression early in dementia diagnosis may be associated with subsequent depressive symptoms in caregivers. Future longitudinal analyses of the dementia caregiving relationship should continue to examine the negative impact of persistent agitation/aggression in the diagnosis of early stage dementia on caregivers.

Caregiver burden associated with behavioral and psychological symptoms of dementia in elderly people in the local community.

BACKGROUND: Despite many studies about the association between caregiver burden and behavioral and psychological symptoms of dementia (BPSD), there have been no population-based studies to evaluate caregiver burden associated with each BPSD. OBJECTIVE: To evaluate caregiver burden associated with the individual BPSD in elderly people living in the community. METHODS: The subjects were 67 participants with dementia living with their caregivers (diagnosed in the third Nakayama study): 51 Alzheimer's disease, 5 vascular dementia and 11 other. The Neuropsychiatric Inventory (NPI) and NPI Caregiver Distress Scale (NPI-D) were used to assess subjects' BPSD and related caregiver distress, respectively. RESULTS: In the subjects exhibiting BPSD, aberrant motor behavior had the highest mean NPI score, and depression/dysphoria had the lowest. Agitation/aggression had the highest mean NPI-D score, and euphoria/elation had the lowest. Delusion, agitation/aggression, apathy/indifference, irritability/lability and aberrant motor behavior showed a correlation between the NPI and NPI-D scores. CONCLUSION: The burden associated with BPSD is different for each symptom and does not always depend on frequency and severity of BPSD. These findings suggest that some symptoms, such as agitation/aggression and irritability/lability, may affect the caregivers significantly, although their frequency and severity are low.

Affective processes in the onset and persistence of psychosis.

OBJECTIVES: Cognitive models suggest that beliefs and appraisal processes are crucially important in the onset and persistence of psychosis. This study investigated whether (i) neuroticism increases the risk for development of psychotic symptoms, and (ii) a delusional interpretation and/or a depressed response to hallucinatory experiences predicts the onset of psychotic disorder. METHOD: A general population sample with no lifetime evidence of any psychotic disorder was interviewed with the Composite International Diagnostic Interview Schedule (CIDI) at baseline and 1 and 3 years later. At year 3, individuals with CIDI evidence of psychotic symptoms were interviewed by clinicians to identify onset of psychotic disorder. RESULTS: Baseline level of neuroticism increases the risk for incident psychotic symptoms. Given the presence of hallucinatory experiences at baseline, the increase in risk of having the psychosis outcome was much higher in the group with delusional ideation or depressed mood at year 1 than in those without delusional ideation or depressed mood. CONCLUSION: A cognitive style characterised by a tendency to worry increases the risk for newly developed psychotic symptoms. Individuals who report hallucinatory experiences and react to these with a delusional interpretation and/or negative emotional states have an increased risk for developing clinical psychosis.

Cognitive behavioral therapy in the treatment of schizophrenia.

This review outlines the role that cognitive behavioral therapy can play in specifically addressing the distress associated with the symptoms of schizophrenia, such as hallucinations and delusions. Some of the features that are given greater emphasis (or are a feature of working with people with psychotic illness), engagement, understanding the onset of the illness and work with hallucinations and delusional beliefs are outlined. The evidence base for the utility of cognitive behavioral therapy is considered, and the development and further application of cognitive behavioral therapy for schizophrenia and related disorders are outlined.

Body dysmorphic disorder: a review of conceptualizations, assessment, and treatment strategies.

Increased interest in body dysmorphic disorder (BDD) has generated a wealth of recent research. This paper reviews the current literature regarding conceptualizations of the disorder, the development of assessment tools, and treatment outcome. Although BDD has been viewed as a variant of an eating disorder, obsessive compulsive disorder, or a somatoform disorder, it appears best conceptualized as a body image disorder with social, psychological, and possibly biological influences. Assessment instruments with acceptable psychometric properies have been developed to specifically assess BDD (e.g., the Body Dysmorphic Disorder Examination and the Yale-Brown Obsessive Compulsive Scale modified for Body Dysmorphic Disorder). Examination and the initial results from uncontrolled and controlled treatment research suggest that cognitive behavioral treatments for BDD may be as effective as those for possibly related disorders such as obsessive compulsive disorder and bulimia nervosa.

Positive and negative symptoms in the psychoses: principal components analysis of items from the Scale for the Assessment of Positive Symptoms and the Scale for the Assessment of Negative Symptoms.

The present study investigated the factor structure of the items contained in Andreasen's scales for the assessment of positive and negative symptoms (SAPS and SANS) by use of a series of principal components analyses (PCAs) with oblique rotations of the axes. It was found that the structure could be summarized by three major components labeled negative symptoms, thought disorder, and delusions/hallucinations. Dimensionality could meaningfully be increased to five components. Negative symptoms was found to separate into two components that we labeled negative signs and social dysfunctions. The delusions/hallucinations factor could be separated into two components, delusions and hallucinations, with "loss of boundary" delusions being related to both factors. Delusions of persecution were independent of other symptoms. The thought disorder factor did not decompose meaningfully within the investigated dimensionality. A two-factor solution did not explain the correlation between symptoms adequately. The results do not support the simple dichotomy between positive and negative symptoms in psychosis, but suggest that a wider dimensional concept may be more useful in future studies.
