Abstract
Importance Although adults with schizophrenia have an increased risk of suicide, sample size limitations of previous research have hindered characterizations of suicide risk across the life span. Objective To describe suicide mortality rates and correlates among adults with schizophrenia across the life span and standardized mortality ratios (SMRs) for suicide compared with the general US population. Design, Setting, and Participants Five national retrospective longitudinal cohorts of patients with schizophrenia in the Medicare program from January 1, 2007, to December 31, 2016, were identified by age: 18 to 34, 35 to 44, 45 to 54, 55 to 64, and 65 years or older. Death record information was obtained from the National Death Index. The total cohort included 668 836 Medicare patients with schizophrenia, 2 997 308 years of follow-up, and 2218 suicide deaths. Data were analyzed from September 30, 2020, to March 10, 2021. Main Outcomes and Measures For each age group, suicide mortality rates per 100 000 person-years and adjusted hazard ratios (aHRs) with 95% CIs of suicide were determined. Suicide SMRs were estimated for the total cohort and by sex and age cohorts standardized to the general US population by age, sex, and race/ethnicity. Results The study population of adults 18 years and older included 668 836 Medicare recipients with schizophrenia (52.5% men, 47.5% women). The total suicide rate per 100 000 person-years was 74.00, which is 4.5 times higher than that for the general US population (SMR, 4.54; 95% CI, 4.35-4.73) and included a rate of 88.96 for men and 56.33 for women, which are 3.4 (SMR, 3.39; 95% CI, 3.22-3.57) and 8.2 (SMR, 8.16; 95% CI, 7.60-8.75) times higher, respectively, than the rates for the general US population. Suicide rates were significantly higher for men (aHR, 1.44; 95% CI, 1.29-1.61) and those with depressive (aHR, 1.32; 95% CI, 1.17-1.50), anxiety (aHR, 1.15; 95% CI, 1.02-1.30), drug use (aHR, 1.55; 95% CI, 1.36-1.76), and sleep disorders (aHR, 1.22; 95% CI, 1.07-1.39), suicidal ideation (aHR, 1.41; 95% CI, 1.22-1.63), and suicide attempts or self-injury (aHR, 2.48; 95% CI, 2.06-2.98). The adjusted hazards of suicide were lower for Hispanic patients (aHR, 0.66; 95% CI, 0.54-0.80) or Black patients (aHR, 0.29; 95% CI, 0.24-0.35) than White patients. The suicide rate declined with age, from 141.95 (SMR, 10.19; 95% CI, 9.29-11.18) for patients aged 18 to 34 years to 24.01 (SMR, 1.53; 95% CI, 1.32-1.77) for patients 65 years or older. The corresponding declines per 100 000 person-years were from 153.80 (18-34 years of age) to 34.17 (65 years or older) for men and from 115.70 (18-34 years of age) to 18.66 (65 years or older) for women. In the group aged 18 to 34 years, the adjusted hazards of suicide risk were significantly increased for patients with suicide attempt or self-injury (aHR, 2.57; 95% CI, 18.20-2.04) and with comorbid drug use disorders (aHR, 1.48; 95% CI, 1.17-1.88), but not with comorbid depressive disorders (aHR, 0.99; 95% CI, 0.38-1.26) during the year before the start of follow-up. Conclusions and Relevance In this cohort study of adult Medicare patients with schizophrenia, suicide risk was elevated, with the highest absolute and relative risk among young adults. These patterns support suicide prevention efforts with a focus on young adults with schizophrenia, especially those with suicidal symptoms and substance use.

Abstract
Older adults diagnosed with schizophrenia (OADWS) often enter long-term care facilities with unique challenges related to trauma and stress experienced throughout their life course. Health care workers often report that when they work with this population, they feel unprepared due to limited training. In this article, life course theory is presented as a lens for holistic nursing research and as a way for nurses to adapt interventions already used with cognitively impaired older adults (e.g., those diagnosed with Alzheimer's disease) for OADWS in long-term care. It is hoped that these ideas will facilitate discussion of ways to inform training for holistic long-term care of OADWS. Holistic principles of nursing addressed with life course theory as a lens include the following: (a) accounting for strengths and challenges; (b) honoring experiences, values, and health beliefs; (c) viewing interrelationships with the environment; and (d) nurturing of peace, wholeness, and healing.

Abstract
Alzheimer's disease (AD), the most common neurodegenerative dementia, leads to memory dysfunction due to widespread neuronal loss associated with aggregation of amyloidogenic proteins (APs), while schizophrenia (SCZ) represents a major psychiatric disorder characterized by delusions, hallucinations, and other cognitive abnormalities, the underlying mechanisms of which remain obscure. Although AD and SCZ partially overlap in terms of psychiatric symptoms and some aspects of cognitive impairment, the causal relationship between AD and SCZ is unclear. Based on the similarity of APs with yeast prion in terms of stress-induced protein aggregation, we recently proposed that evolvability of APs might be an epigenetic phenomenon to transmit stress information of parental brain to cope with the stressors in offspring. Although amyloid evolvability may be beneficial in evolution, AD might be manifested during parental aging as the mechanism of antagonistic pleiotropy phenomenon. Provided that accumulating evidence implicates stress as an important factor in SCZ, the main objective of this paper is to better understand the possible connection of AD and SCZ through amyloid evolvability. Hypothetically, the delivery of information of stress by APs may be less efficient under the decreased evolvability conditions such as disease-modifying treatment, leading to SCZ in offspring. Conversely, the increased evolvability conditions including gene mutations of APs are supposed to be beneficial for offspring, but might lead to AD in parents. Collectively, AD and SCZ might transgenerationally interfere with each other through amyloid evolvability, and this could explain why both AD and SCZ have not been selected out through evolution.

Abstract
OBJECTIVE People with serious mental illness have dramatically reduced life expectancy that is largely attributed to elevated rates of chronic medical conditions. Several group interventions have been developed and implemented in recent years to improve health and wellness among people with mental health conditions. Unfortunately, attendance in these interventions is often low, and there is limited understanding of factors that influence patient engagement in this treatment modality. METHOD Participants (N = 242) were enrolled in 1 of 2 group-based health and wellness treatment programs. Using descriptive statistics and regression, we assessed treatment attendance and a range of potential predictors of attendance. RESULTS We found lower attendance among people who were younger, people with more medical conditions, and people with more emergency room visits in the 6 months prior to the beginning of treatment. Younger age was a particularly strong predictor of low attendance and was the only variable significantly associated with attending zero treatment sessions. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE These results highlight the need for strategies to improve engagement of patients with poorer objective indicators of medical health and patients with younger age.

Abstract
Older adults diagnosed with schizophrenia (OADWS) have unique needs for care and live longer today than their forebears who were diagnosed with schizophrenia. As a result, nurses need to be prepared for the specific care of individuals who live with schizophrenia as they age. Together, Life Course Theory and holistic nursing suggest a good fit in the quest for successful solutions and/or outcomes for the unique problems that OADWS face. Holistic nursing views the patient as a whole person, considering all aspects of the patient’s experiences within life’s broader environment. The life course paradigm offers an effective way for nurses to understand issues that patients face throughout their lives, thus enhancing holistic nursing with a historical perspective. This is especially important for the care of OADWS, who face unique disparities as well as physical and psychological comorbidities over their life course. This article is intended to initiate a discussion of OADWS, focused with Life Course Theory as a holistic lens. Literature pertinent to the life course of OADWS is reviewed, followed by an analysis of the life course paradigm in relation to OADWS’ unique experiences. Conclusions support the holistic use of Life Course Theory in research and interventions for OADWS.

Abstract
Many older community-living persons with schizophrenia report unmet psychological and social needs. The Amsterdam-based New Club is a novel facility that intends to foster self-reliance and social participation in this group. To explore participants' and staff perceptions, a naturalistic qualitative study combined participant observation with interviews. The results illustrate how the New Club contributes to the personal and social recovery of its participants. At the personal level, attending the facility, activation and feeling accepted were valued positively. At the social level, engaging with others, experiencing a sense of community, and learning from one another's social skills were positive contributors. Next, various environmental factors proved important. The New Club demonstrates the feasibility of creating a facility that offers an accepting and non-demanding social environment to older community-living individuals with severe mental illnesses. It may offer a suitable alternative for the more demanding psychotherapeutic interventions offered to younger populations.

Abstract
Older adults with schizophrenia experience poorer community integration and social functioning compared to same-age peers with no mental health disorders; these individuals are at elevated risk for functional decline and early institutionalization in long-term care facilities. Deficits in thought, language, and communication (TLC; that is, thought disorder and alogia) are core features of schizophrenia and may worsen with age; however, little research focuses on the functional sequelae of these impairments among older adults with schizophrenia. The present study aimed to examine the relationships among age, TLC deficits, and functional outcomes in a sample of community-dwelling middle-aged and older adults with schizophrenia (N = 245; ages 40-85). Participants completed assessments of symptoms, neurocognition, TLC deficits, and functional outcomes. Two different categories of TLC deficits were examined: verbal underproductivity (i.e., alogia) and disconnected speech. Regression analyses, controlling for gender, age, Veteran status, smoking status, cognitive impairment, and symptom severity, found that disconnected speech predicted occupational functioning, while verbal underproductivity predicted capacity to communicate skillfully in semi-structured social situations, as well as community functioning across interpersonal, occupational, and everyday living domains. Exploratory mediation analyses found significant indirect effects of age, through TLC deficits, on certain functional outcomes. Targeted training to improve TLC deficits, especially verbal underproductivity, among older adults with schizophrenia could have downstream effects on community functioning, improving outcomes for a vulnerable group.

Abstract
A crisis looms as research and clinical programs have not kept pace with dramatic increases in the number of older adults with schizophrenia. This article provides an overview of the advances in the conceptualization and study of schizophrenia in later life. Theoretic and clinical models in psychiatry and gerontology are integrated. Specifically, recovery is examined in the context of aging, how clinical dimensionality affects diagnoses in older adults, how various features of schizophrenia are implicated in models of accelerated and paradoxic aging, and how outcome in later life is a more dynamic and heterogeneous than assumed previously.

Abstract
OBJECTIVES Treatment-resistant schizophrenia (TRS) continues to be a challenge in modern psychiatry. Most of these patients have severe neurocognitive deficits. Electroconvulsive therapy (ECT) has proved effective and safe in the treatment of TRS, but because of potential neurocognitive adverse effects, it is associated with many controversies. The aim of this prospective, open study was to evaluate the effects of ECT augmentation of antipsychotics on cognitive functions in patients with TRS. METHODS Overall, 31 inpatients with TRS were included, 16 men, with an average (SD) age of 34.1 (11.187) years. The evaluation of clinical symptoms and global impression, as well as verbal memory, visual memory, working memory, psychomotor speed, verbal fluency, and executive functioning, was conducted before and after the completion of ECT treatment. RESULTS We ran a series of paired-samples t tests, and the Bonferroni adjustment for multiple comparisons reduced the significance level to P = 0.004. The neurocognitive domains that demonstrated statistically significant improvement were immediate and delayed verbal memory, and executive functioning, whereas statistical trend was observed for visual memory and psychomotor speed. None of the neurocognitive functions exhibited significant deterioration after the ECT treatment. Electroconvulsive therapy was effective in reducing general symptoms of schizophrenia, resulting in more than 30% decrease in the overall symptom severity measured by the Positive and Negative Syndrome Scale. CONCLUSIONS Notwithstanding some limitations of this study, the combination of ECT and antipsychotics has improved several neurocognitive domains, without evidence of worsening of any cognitive functions.

Abstract
OBJECTIVE Preserved social functioning is of utmost importance for older individuals living in the community to maintain independency. However, in patients with schizophrenia or bipolar disorder, it remains unclear which factors influence social functioning in later life. METHODS In a catchment area-based study in Amsterdam, The Netherlands, 120 older (>60 years) community-living patients with schizophrenia (n = 73) and with bipolar disorder (n = 47) were included. Clinical interviews on social functioning and psychometric measurements were applied. RESULTS Patients with schizophrenia scored lower on all social measures (social functioning, social participation, network size, availability of confidants) compared with their peers with bipolar disorder. In patients with schizophrenia, lower social functioning was associated with having more negative symptoms and depressive symptoms. Age of onset was also associated with social functioning in schizophrenia, with higher scores in very late-onset schizophrenia-like psychosis. Unfavourable social functioning in patients with bipolar disorder was associated with lower cognitive functioning. Furthermore, in both groups, social functioning was not related to age, having offspring or the presence of a partner. CONCLUSIONS In community-living older patients, schizophrenia has a more disruptive effect on social functioning than bipolar disorder, except in those with a very late-onset schizophrenia-like psychosis. Minimizing residual depressive symptoms and optimizing cognitive functioning may be targets for improving social functioning and independent-living in older patients with severe mental illness.

Abstract
The UCSD Performance-based Skills Assessment (UPSA) is a widely used measure of functional capacity with strong reliability and validity. However there is a lack of psychometric data on Hispanics. The purpose of this study was to determine the impact of acculturation and education on UPSA performance among 62 Hispanic participants with schizophrenia or schizoaffective disorder and 46 healthy comparison subjects. Functional capacity was measured using the UPSA. Acculturation was measured using the Acculturation Rating Scale for Mexican Americans (ARSMA). Independent t-tests indicated that participants with schizophrenia had significantly lower UPSA total scores and scored lower on all UPSA sub-scales relative to the comparison group. Multiple regression also indicated that education and acculturation were significant predictors of UPSA total scores. These data provide a better understanding of UPSA scores in Hispanics with and without schizophrenia, and suggest that education and acculturation adjustments may be required to improve interpretation of test results.

Abstract
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).

Abstract
The aim of this study was to explore the subjective experience of suffering in aging individuals with schizophrenia. Qualitative interviews were conducted with 18 participants aged 60-69. Phenomenological content analysis was performed. Nine dimensions of suffering emerged: social rejection; familial rejection; the symptoms of schizophrenia; hospitalisation; the side effects of medication; loss of employment potential; loss of independent accommodation; loss of social life, and loss of hope to be a partner and a parent. The suffering of aging people with schizophrenia is cumulative and ongoing and thus evokes issues such as existential loneliness and feelings of homelessness.

Abstract
Worldwide, in the past few decades, the demographics of older people (ie, people 55 years and over) with schizophrenia have changed completely with respect to absolute numbers of people affected, the proportion of all people with the disorder, life expectancy, and residential status. The ageing schizophrenia population has created vast health-care needs and their medical comorbidity contributes to higher mortality than in the general population. Proposals to classify schizophrenia into early-onset, late-onset, and very-late-onset subtypes now should be tempered by the recognition that comorbid medical and neurological disorders can contribute to psychotic symptoms in later life. The concept of outcome has become more nuanced with an appreciation that various outcomes can occur, largely independent of each other, that need different treatment approaches. Data show that schizophrenia in later life is not a stable end-state but one of fluctuation in symptoms and level of functioning, and show that pathways to improvement and recovery exist. Several novel non-pharmacological treatment strategies have been devised that can augment the clinical options used to address the specific needs of older adults with schizophrenia.

Abstract
BACKGROUND Depressive symptoms frequently accompany schizophrenia. Older patients constitute the fastest growing segment of the schizophrenia population. With regard to the risk factors associated with depression, it is uncertain to which extent older schizophrenia patients differ from their age peers in the community. METHODS We assessed self-reported depressive symptoms in an epidemiological sample of older Dutch community-living patients with schizophrenia or schizoaffective disorder (N=99; mean age 67years). Demographic, clinical and social variables were evaluated for their predictive value on the level of depressive symptoms. A comparison group, proportionally matched for age and gender, was recruited from a community study. RESULTS In the schizophrenia group, 47.5% reported depressive symptoms at a level indicating clinically relevant depression, in contrast to 12.1% in their age peers (odds ratio 6.55; 95% CI, 3.19-13.48; p<0.001). This difference could not be explained by differential exposure to the evaluated general risk factors. In both groups, functional limitations were the strongest predictor of depressive symptoms. In the patient group, chronic physical disorders and lack of a confidant were predictors, while a diagnosis of schizoaffective disorder (vs. schizophrenia) was the only disorder-related risk factor that contributed to depressive symptoms, with marginal significance. CONCLUSION The high rate of depressive symptoms in this epidemiological sample of older schizophrenia patients confirms that these symptoms frequently accompany this severe mental illness in late life. With physical and social factors as important predictors of depressive symptoms, risk factors for depression are more comparable between older schizophrenia patients and their age peers than is often assumed.

Abstract
BACKGROUND The purpose of this article was to conduct a review of the types of training offered to people with schizophrenia in order to help them develop strategies to cope with or compensate for neurocognitive or sociocognitive deficits. METHODS We conducted a search of the literature using keywords such as "schizophrenia", "training", and "cognition" with the most popular databases of peer-reviewed journals. RESULTS We reviewed 99 controlled studies in total (though nine did not have a control condition). We found that drill and practice training is used more often to retrain neurocognitive deficits while drill and strategy training is used more frequently in the context of sociocognitive remediation. CONCLUSIONS Hypotheses are suggested to better understand those results and future research is recommended to compare drill and strategy with drill and practice training for both social and neurocognitive deficits in schizophrenia.

Abstract
OBJECTIVE Theory of Mind (ToM) is considered an essential element of social cognition. In younger schizophrenia patients, ToM impairments have extensively been demonstrated. It is not clear whether similar impairments can be found in older schizophrenia patients and if these impairments differ between older patients with early-onset and late-onset schizophrenia. METHODS Theory of Mind abilities were assessed using the Hinting Task in 15 older patients (age 60 years and older) with early-onset paranoid schizophrenia, 15 older patients with late-onset paranoid schizophrenia and 30 healthy controls. ANCOVA was performed to test differences between groups. Analyses were adjusted for level of education. Effect sizes, partial eta squared (ε(2) ), were computed as an indication of the clinical relevance of the findings. RESULTS Patients with early-onset schizophrenia scored significantly lower on the Hinting Task (mean 16.1; SD 4.3) compared with patients with late-onset schizophrenia (mean 18.6; SD 1.5) and with healthy controls (mean 19.0; SD 1.4). The effect size of this difference was large (ε(2) = 0.2). CONCLUSIONS These results suggest that ToM functioning may be a protective factor modulating the age at onset of psychosis. Further studies into the relationship between social cognition and onset age of psychosis are warranted.

Abstract
PURPOSE Reported employment rates for patients with psychosis are low, but vary partly depending on illness phase. Illness-related factors such as neurocognition and negative symptoms are associated with occupational functioning, while external factors may also act as barriers for employment. The current study investigated the relationship between neurocognition, symptoms and employment using a threefold division of employment status: employed, receiving temporary benefits and receiving disability benefits. The latter group was divided into two based on level of social functioning. METHODS A total of 155 patients with broad DSM-IV schizophrenia spectrum disorder were assessed with clinical, neurocognitive and social and occupational functioning measures. Group differences were analyzed with ANOVAs and hierarchical regression analysis. RESULTS Thirteen percent were employed, 52 % received temporary benefits and 35 % received disability benefits. There were no differences in symptom level and neurocognitive functioning between groups. Among patients on disability benefits, the subgroup with higher social functioning had fewer negative and general symptoms and a trend for better neurocognition compared with those with lower social functioning, thus being more similar to employed patients. Negative symptoms and executive functioning explained 26 % of the variance in social functioning for patients receiving disability benefits. CONCLUSIONS The association between neurocognition and employment may not be as strong as previously assumed, due to external factors that may influence this relationship. Patients on disability benefits rated high on social functioning showed similarities with employed patients. This could imply that these patients have some work capacity. This issue needs further investigation.

Abstract
OBJECTIVE Elderly people with schizophrenia often suffer from cognitive impairments, which affect their social functioning. Today, only a few therapy approaches for middle-aged and older patients are available. The Integrated Psychological Therapy (IPT) combines neurocognitive and social cognitive interventions with social skills approaches. The aim of this study was to evaluate (1) whether IPT is effective in younger patients (age < 40 years) and middle-aged patients (age ≥ 40 years) and (2) whether control conditions (treatment as usual or unspecific group activities) reveal some change in outcome depending on age. METHOD A total of 15 controlled IPT studies with 632 inpatients with schizophrenia were evaluated in a standard meta-analytic procedure. Studies were categorized into two age categories. RESULTS Significant medium to large effect sizes (ES) were evident for IPT independent of age on the global cognitive score (mean score of all cognitive variables), on neurocognition, social cognition, social functioning, psychopathology, and the global therapy effect (mean of all variables). The IPT effects in middle-aged patients were significantly larger on the global cognitive score, on neurocognition, and on social cognition compared with younger patients. Opposite results could be observed in control conditions. Only younger patients participating in the control conditions showed small but significant ES on these variables, but almost middle-aged control patients did not. However, none of the differences in the control conditions were significant between the two age categories. A moderator analysis obtained no evidence for a strong impact of IPT variations, therapy setting, patient characteristics, and methodologic rigor of the research design. CONCLUSIONS These results support evidence for the efficacy of IPT independent of age. Results further indicate the need of goal-oriented specific psychological interventions for middle-aged and older patients with schizophrenia.

Abstract
OBJECTIVE Elderly patients constitute the fastest growing segment of the schizophrenia population. Still, their needs for care are poorly understood. This study aimed to gain insight into the care needs of older patients with schizophrenia spectrum disorders. SETTING AND PARTICIPANTS Patients, aged 60 years and older, in contact with mental health services within a Dutch psychiatric catchment area, diagnosed with schizophrenia spectrum disorders. MEASUREMENTS Needs and the extent to which these were met were assessed from the perspective of both patients and staff members. Agreement between patients and staff on the presence of needs was evaluated. In addition, the association between patient characteristics and the number of unmet needs was examined. RESULTS On average, patients (N = 114, mean age: 69 years) reported 7.6 needs, of which 6.1 were met and 1.5 were unmet. Staff members reported slightly more needs, both met and unmet. Patients and staff showed consensus on the presence of most needs, but discrepancies existed in individual need areas. Psychological and social needs were unmet more often than environmental and physical needs. The number of unmet needs correlated with several patient variables, with the strongest association found for self-reported quality of life. CONCLUSION In elderly schizophrenia patients, similar to what has been reported in younger patients, psychological and social needs appear to be under serviced. Having more unmet needs was associated with a lower perceived quality of life.

Abstract
BACKGROUND Schizophrenia is a significantly disabling disease that affects all major areas of life. There is a lack of comprehensive synthesis of research findings on the full extent of psychosocial difficulties (PSDs) experienced by people living with schizophrenia. This paper provides a systematic review of the literature concerning PSDs and their associated factors in schizophrenia. PSDs were conceptualized in accordance with the International Classification of Functioning, Disability and Health (ICF) as disabilities, in particular impairments of mental functions, activity limitations and participation restrictions. METHODS An electronic search using MEDLINE and PsychINFO plus a manual search of the literature was performed for qualitative and longitudinal studies published in English between 2005 and 2010 that examined PSDs in persons with schizophrenia. The ICF was used as a conceptual framework. RESULTS A total of 104 papers were included. The most frequent PSDs addressed in the literature were not specific ones, directly linkable to the ICF categories of mental functions, activity limitations or participation restrictions, but broad areas of psychosocial functioning, such as psychopathological symptoms (53% of papers) or global disability and functioning (37%). Among mental functions, the most extensively studied were cognitive functions (27%) and emotional functions (27%). Within the domain of activities and participation, the most widely investigated were difficulties in relationships with others (31%) and employment (20%). Of the factors associated with the intensity or course of PSDs, the most commonly identified were treatment modalities (56%), psychopathological symptoms (26%), and socio-demographic variables (24%). Medication tended to improve the most relevant PSD, but at the same time was the only consistently reported determinant of onset of PSDs (emerging as unwanted side-effects). CONCLUSIONS The present review illustrates the remarkably broad scope and diversity of psychosocial areas affected in schizophrenia and shows how these areas are interconnected and how they interact with contextual factors. The need for a shift in focus of schizophrenia research is suggested--from an excessive reliance on global measures of psychopathology and disability for defining outcomes to the creation of profiles of specific PSDs that have a more direct bearing on the disabling experience and real-world functioning of patients and can serve to guide interventions and monitoring over time.

Abstract
BACKGROUND Although clozapine is primarily used in a younger to mid-life population of patients with psychosis, there are limited data on the clinical pharmacology of clozapine later in life. The objective of this study was to assess the magnitude and variability of plasma concentrations of clozapine and norclozapine across the lifespan in a real-world clinical setting. DESIGN A population pharmacokinetic study using nonlinear mixed effect modeling (NONMEM). Age, sex, height, weight, and dosage formulation were covariates. SETTING Inpatients and outpatients at the Centre for Addiction and Mental Health, Toronto, from 2001 to 2007. PARTICIPANTS Patients ranging in ages from 11 to 79 with schizophrenia spectrum disorders and prescribed clozapine (Clozaril). MEASUREMENTS A total of 1142 plasma clozapine and norclozapine concentrations (2,284 concentration measurements) from 391 patients with schizophrenia spectrum disorder. RESULTS A one-compartment model with first-order absorption and elimination best described the data. The population predicted clearance of clozapine for females was 27.1 L/h (SE 11.1%) and 36.7 L/h (SE 9.7%) for males. For norclozapine, clearance in females was 48.6 L/h (SE 10.8%) and 63.1 L/h (SE 9.3%) in males. The only covariates with a significant effect on clearance were age and sex: clearance for both parent and metabolite decreased exponentially with age at least 39 years. CONCLUSIONS Decreased clearance of clozapine and norclozapine with age results in increased blood concentrations and, hence, the potential for adverse drug reactions. These findings have particular clinical relevance for the dosing and safety monitoring of clozapine in older adults, highlighting a need for increased vigilance.

Abstract
OBJECTIVES The loss of long-term inpatient psychiatric hospital beds over the years has caused schizophrenia patients of all ages to be increasingly placed in nursing home environments that were traditionally reserved for elderly patients. Consequently, many nongeriatric patients with chronic schizophrenia are now residing in nursing home settings. The objective of this article is to determine whether many of these nongeriatric patients are placed in nursing homes because of chronicity of illness and severity of impairment, or because of the limited alternative viable housing options. DESIGN Multiple and stepwise regressions examined predictors of cognitive ability, adaptive competence, social skills and inpatient social and adaptive functioning, and clinical symptomatology. SETTING Inpatient psychiatric unit in a general hospital. PARTICIPANTS Fifty acutely ill geriatric and nongeriatric patients with schizophrenia who reside in nursing homes. MEASUREMENTS Participants' clinical symptoms, cognitive ability, adaptive functioning, social skills, and inpatient social and adaptive functioning were assessed. RESULTS Findings revealed that patients' cognitive impairment and age of admission to the nursing home, irrespective of patients' current age, were predictors of impaired adaptive competence. CONCLUSIONS Examination of cognitive and adaptive deficits with assessment of symptom severity, independent of patients' current age, may aide in the determination of appropriate residential placements for individuals with schizophrenia.

Abstract
BACKGROUND Symptomatic remission and its associated factors have been evaluated in several studies of younger schizophrenic patients. Although the number of older individuals with schizophrenia is rapidly growing, evaluations of remission in elderly patients are scarce and limited to samples of convenience, questioning their generalizability to unselected patient populations. METHODS We assessed the rate of symptomatic remission in a cohort of older Dutch schizophrenic patients within a psychiatric catchment area. In addition, we examined the association of symptomatic remission with measures of mental health treatment, social functioning, cognition, mood, and quality of life. RESULTS With a rate of 29.4%, symptomatic remission in this catchment area based cohort of older schizophrenic patients (mean age 68 years) was markedly lower than the rates reported for convenience samples. Remission was more frequent in schizoaffective patients, compared to patients with schizophrenia. Remitted patients were more adherent to psychiatric services and scored higher on measures of social functioning. No association with symptomatic remission could be demonstrated for cognition, mood, and quality of life. CONCLUSION The modest rate of symptomatic remission in this treated sample of elderly schizophrenic patients questions the notion that old age is associated with high levels of symptomatic remission. The concurrent validity of the remission concept in elderly patients merits further investigation, given the limited number of demonstrated associations.
