Abstract Sleep disturbances are prevalent among older adults and are associated with various individual diseases. The goal of this study was to investigate whether sleep disturbances are associated with the speed of multimorbidity development among older adults. Data were gathered from the Swedish National study of Aging and Care in Kungsholmen (SNAC-K), an ongoing population-based study of subjects aged 60+ (N=3363). The study included a subsample (n=1189) without multimorbidity at baseline (<2 chronic diseases). Baseline sleep disturbances were assessed using the Comprehensive Psychiatric Rating Scale, and categorized as none, mild, moderate-severe. The number of chronic conditions throughout the nine-year follow-up was obtained from clinical examinations. Linear mixed models were used to study the association between sleep disturbances and the speed of chronic diseases accumulation, adjusting for sex, age, education, physical activity, smoking, alcohol consumption, depression, pain, and psychotropic drug use. We repeated the analyses including only cardiovascular, neuropsychiatric, and musculoskeletal diseases as the outcome. Moderate-severe sleep disturbances were associated with a higher speed of chronic disease accumulation (ß/year=0.142, p=0.008), regardless of potential confounders. Significant positive associations were also found between moderate-severe sleep disturbances and neuropsychiatric (ß/year=0.041, p=0.016) and musculoskeletal (ß/year=0.038, p=0.025) disease accumulation, but not with cardiovascular diseases. Results remained stable when participants with baseline dementia, cognitive impairment, or depression were excluded. The finding that sleep disturbances are associated with faster chronic disease accumulation points towards the importance of early detection and treatment of sleep disturbances as a possible strategy to reduce chronic multimorbidity among older adults.

Abstract Background Sleep disturbances are prevalent among older adults and are associated with various individual diseases. The aim of this study was to investigate whether sleep disturbances are associated with the speed of multimorbidity development among older adults. Methods Data were gathered from the Swedish National study of Aging and Care in Kungsholmen (SNAC-K), an ongoing population-based study of subjects aged 60+ (N = 3363). The study included a subsample (n = 1189) without multimorbidity at baseline (< 2 chronic diseases). Baseline sleep disturbances were derived from the Comprehensive Psychiatric Rating Scale and categorized as none, mild, and moderate–severe. The number of chronic conditions throughout the 9-year follow-up was obtained from clinical examinations. Linear mixed models were used to study the association between sleep disturbances and the speed of chronic disease accumulation, adjusting for sex, age, education, physical activity, smoking, alcohol consumption, depression, pain, and psychotropic drug use. We repeated the analyses including only cardiovascular, neuropsychiatric, or musculoskeletal diseases as the outcome. Results Moderate–severe sleep disturbances were associated with a higher speed of chronic disease accumulation (ß/year = 0.142, p = 0.008), regardless of potential confounders. Significant positive associations were also found between moderate–severe sleep disturbances and neuropsychiatric (ß/year = 0.041, p = 0.016) and musculoskeletal (ß/year = 0.038, p = 0.025) disease accumulation, but not with cardiovascular diseases. Results remained stable when participants with baseline dementia, cognitive impairment, or depression were excluded. Conclusion The finding that sleep disturbances are associated with faster chronic disease accumulation points towards the importance of early detection and treatment of sleep disturbances as a possible strategy to reduce chronic multimorbidity among older adults.

Abstract The author, who is the editor of the Mental and Behavioral Disorders chapter of the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Sixth Edition, comments on the previous article, Assessing Mental and Behavioral Disorder Impairment: Overview of Sixth Edition Approaches in this issue of The Guides Newsletter. The new Mental and Behavioral Disorders (M&BD) chapter, like others in the AMA Guides, is a consensus opinion of many authors and thus reflects diverse points of view. Psychiatrists and psychologists continue to struggle with diagnostic taxonomies within the Diagnostic and Statistical Manual of Mental Disorders, but anxiety, depression, and psychosis are three unequivocal areas of mental illness for which the sixth edition of the AMA Guides provides M&BD impairment rating. Two particular challenges faced the authors of the chapter: how could M&BD disorders be rated (and yet avoid an onslaught of attorney requests for an M&BD rating in conjunction with every physical impairment), and what should be the maximal impairment rating for a mental illness. The sixth edition uses three scales—the Psychiatric Impairment Rating Scale, the Global Assessment of Function, and the Brief Psychiatric Rating Scale—after careful review of a wide variety of indices. The AMA Guides remains a work in progress, but the authors of the M&BD chapter have taken an important step toward providing a reasonable method for estimating impairment.

Insomnia Severity

Abstract Personality and disturbed sleep are tied to medical morbidity in older adults. We examined associations of personality dimensions and facets from the five-factor model with reports of insomnia symptoms in 1,069 well-functioning older adults 60-97 (SD=8.64) years (51% women) from the Baltimore Longitudinal Study of Aging. Personality was assessed by the Revised NEO Personality Inventory, and insomnia symptoms measured by the Women’s Health Initiative Insomnia Rating Scale. Adjusting for demographics and depressive symptoms, higher neuroticism (B=0.05, SE=-0.01, p&lt;.001) and lower conscientiousness (B=-0.03, SE=-0.01, p&lt;.05) were associated with greater insomnia severity. Although openness, extraversion and agreeableness were not associated with insomnia, a facet of each was. Higher scores on the “positive emotions” facet of extraversion (B =-0.03, SE=-0.01, p&lt;.05) “ideas” facet of openness (B=-0.03, SE=-0.01, p&lt;.05) and altruism facet of agreeableness (B=-0.03, SE=-0.01, p&lt;.05) were associated with lower insomnia severity. Sleep disturbances may partially mediate personality’s influence on health. Part of a symposium sponsored by the Sleep, Circadian Rhythms and Aging Interest Group.

RésuméLe présent travail comporte une critique de la méthodologie employée pour définir une typologie des schizophrènes et une étude empirique de la distinction entre forme productive et forme déficitaire.Après avoir souligné que les études factorielles visant l’identification de deux types de schizophrènes reposaient sur des choix méthodologiques discutables: recherche de corrélations entre variables, alors qu’il s’agit de découvrir des corrélations entre sujets; préférence pour des relations symétriques, alors que les liaisons sont probablement d’ordre asymétrique, les auteurs présentent deux études empiriques.La première réalisée sur un échantillon de 99 schizophrènes s’appuie sur la factorisation des estimations de la symptomatologie (BPRS* á 42 items) à l’aide de la méthode factorielle en plan Q et d’une analyse des correspondances. La seconde a porté sur un sous-échantillon de 52 schizophrènes à l’aide d’une nouvelle méthode d’analyse hiérarchique (HICLAS). Les résultats de ces analyses aboutissent aux conclusions suivantes. Les résultats des analyses factorielles montrent: • qu’il existe plus de deux formes de schizophrènie et qu’à l’intérieur des classes formées par les individus l’opposition déficitaire -productif est stable quelle que soit la métrique utilisée; • que cette opposition repose principalement, pour ce qui est de la forme déficitaire sur 3 symptômes: l’émoussement affectif, le retrait affectif et le ralentissement, et pour ce qui est de la forme productive sur l’humeur expansive, l’attitude manipulatoire, l’excitation, la dramatisation et la labilit émotionnelle; • que contrairement aux travaux antérieurs ni les hallucinations ni la désorganisation conceptuelle ne permettent d’établir la différence entre les deux groupes de malades sans doute parce qu’elles sont communes à tous les schizophrènes; • qu’il n’y a pas de correspondance entre les diagnostics cliniques et les formes décrites; et, • que les malades les plus déficitaires (situés aux extrêmités du pole factoriel) se différencient des malades productifs essentiellement par des variables liées au sexe (plus d’hommes que de femmes dans le premier cas), un statut marital de célibat plus fréquent, et des antécédents psychiatriques plus importants. Les résultats des analyses factorielles soulignent d’une part que les types mixtes sont plus fréquents que les types purs et, d’autre part qu’il suffit de moins de 10 symptômes pour réaliser une opposition satisfaisante entre forme productive et forme déficitaire (Tableau 3, figure 1).Toutes ces conclusions sont valables aussi pour l’analyse hiérarchique. Mais de plus, cette méthode permet d’individualiser un groupe de malades “purs” dans la forme déficitaire seulement, groupe disjoint des autres individus sur la base d’un très petit nombre de symptômes. A côté de ces types purs figurent des types mixtes, qui possédent à la fois des symptômes déficitaires et des symptômes productifs suivant des combinaisons hiérarchiques précises, c’est-à-dire avec une dominance de l’une ou de l’autre forme. Il existe aussi des formes résiduelles dans lesquelles aucune hiérarchie ne peut être mise au jour (Tableau 4).En conclusion on a insisté, outre les problèmes méthodologiques négligés dans les précédentes recherches, sur l’existence d’une dissymétrie entre la forme déficitaire et la forme productive, dans la mesure où c’est seulement la forme déficitaire qui présente une grande singularité et sur l’importance des symptômes liés à la vie affective et à son appauvrissement qui ont un pouvoir discriminatif plus élevé que les symptômes productifs.*BPRS = Brief Psychiatric Rating Scale

Psychiatric Rating Scale

This study investigates the pharmacokinetic (PK) and pharmacodynamic (PD) consequences of shifting from Quetiapine fumarate immediate-release (IR) to extended-release (XR) formulation in non-adherent schizophrenia patients. Monte-Carlo simulations using population PK and PD models were implemented to predict the time course of plasma concentration and Brief Psychiatric Rating Scale (BPRS) scores following the oral administration of 200 mg Seroquel® every 12 h and 400 mg Seroquel XR® every 24 h in patients experiencing dose delay, omission or doubling. Parameters were computed and their distributions were compared using the Kolmogorov–Smirnov test. Dose irregularities with both formulations had different effects on plasma concentration and %reduction in BPRS scores from baseline. However, the odds ratio of getting a %reduction in BPRS below 14%, or plasma concentration exceeding 500 µg/L, were comparable for adherent and non-adherent patients. Plasma therapeutic concentration after treatment cessation was maintained for <24 h in 48% and 29.6% of patients, and a steady state recovery time of <48 h was achieved in 51% and 13.4% of patients on the IR and XR formulations, respectively. Monte-Carlo simulations predict that the risks associated with the IR dose irregularities are not worsened when the XR formulation is used instead. Non-adherence events involving a single dose of either formulation do not require rescue doses.

High Doses

A radioreceptor assay (RRA) was used to determine the neuroleptic plasma levels of 32 outpatients with schizophrenia receiving a high dose of neuroleptics (the equivalent of 18 mg or more of oral haloperidol per day) and undergoing a 50% partial and progressive reduction (ten percent each month for five months) in their medication. Plasma levels of neuroleptics were measured three times: before (T1) and immediately after the 50% reduction (T2) and five months later (T3). A linear correlation was observed between neuroleptic plasma levels obtained by RRA and the neuroleptic doses prescribed at T1 and T3. Furthermore, neuroleptic plasma levels were significantly lower at T3 than at T1. Concurrent evaluations of psychopathology were done using the Brief Psychiatric Rating Scale, and the results indicated that no correlation exists between neuroleptic plasma levels and the total rating scale scores at T1 but a significant correlation was observed at T3.

Schizophrenic Outpatients

This paper presents an open study which evaluated the clinical effects of a partial and progressive reduction in neuroleptic medication in 32 outpatients suffering from schizophrenia who were receiving high doses (equivalent of ≥ 18 mg of oral haloperidol per day; EHL). After an observation period of twelve weeks, each subject's dose of neuroleptics was reduced by 50% at the rate of 10% every four weeks. Patients were receiving a mean of 62 mg per day EHL at the beginning of the study and 30 mg per day EHL at the completion of the study. After the reduction, the following was observed: 1. a significant but modest change in psychopathology: a decrease in negative symptoms and in the total score on Brief Psychiatric Rating Scale; and 2. a significant increase in tardive dyskinesia symptoms. Six subjects relapsed but five of them recovered without increasing their reduced medication. Results of this study are discussed in the context of trying to find a minimal maintenance dose in the treatment of schizophrenia. The relative paucity of change despite a large reduction in medication argues for réévaluation of dosage in patients on high or very high doses of neuroleptics. The results suggest that many patients taking high doses could be maintained on significantly lower doses of neuroleptics. With gradual reduction of medication it would seem that many patients who are receiving a high dose of neuroleptic can achieve a lower dose than their current maintenance level.

The efficacy of ECT was investigated in a double-blind trial. Twenty-two patients with schizophrenia received trifluoperazine and were randomly allocated to receive eight real or eight simulated ECTs. In the first eight weeks, the group receiving real ECTs showed significantly more improvement as measured on the Brief Psychiatric Rating Scale. However, the groups showed no significant differences from the twelfth week onwards. The superiority of real ECT was not confirmed at the end of six months.
