[Older people with complex, combined care needs: the need for tailored collaborative care]. / Ouderen met complexe, gecombineerde problemen: noodzaak tot samenwerken op maat.

Older patients with combined psychiatric, physical and cognitive health problems - patients who need double care - benefit from integrated medical and psychiatric care. The characteristics of these patients, as well as the problems that may exist in offering them adequate integrated care, are illustrated on the basis of a case description. Improvement of existing regional arrangements, premised on a collaborative care model, and involving hospital care, mental health services, nursing home care and community care services, is recommended. In settings that offer 24 hour long-term residential care and treatment, the expertise of mental health services and nursing homes must be structurally combined.

Optimal Detection of Subtle Gadolinium Leakage in CSF with Heavily T2-Weighted Fluid-Attenuated Inversion Recovery Imaging.

Pericortical enhancement on postcontrast FLAIR images is a marker for subtle leptomeningeal blood-brain barrier leakage. We explored the optimal FLAIR sequence parameters for the detection of low gadolinium concentrations within the CSF. On the basis of phantom experiments and human in vivo data, we showed that detection of subtle pericortical enhancement can be facilitated by using a relatively long TE. Future studies should choose their FLAIR sequence parameters carefully when assessing pericortical enhancement due to subtle blood-brain barrier leakage.

An Experience Sampling Method Intervention for Dementia Caregivers: Results of a Randomized Controlled Trial.

OBJECTIVE: Ecological momentary interventions integrated with real-life assessments using the experience sampling method (ESM) could be promising to effectively support dementia caregivers in daily life. This study reports on the effectiveness of the ESM-based intervention "Partner in Sight." DESIGN, SETTING, PARTICIPANTS: A randomized controlled trial with 76 dementia caregivers was performed. Participants were randomly assigned to the intervention group ("Partner in Sight": ESM self-monitoring and personalized feedback), the pseudo-intervention group (ESM self-monitoring without feedback), or the control group (usual care). MEASUREMENTS: Effects were evaluated pre- and postintervention and at 2-month follow-up. Primary outcomes were retrospective measures of caregiver sense of competence and mastery. Secondary outcomes were retrospective measures of depression, anxiety, and perceived stress. Complementary ESM measures of positive and negative affect were collected pre- and postintervention. RESULTS: Both the experimental and pseudo-experimental groups showed an increase in retrospective sense of competence and a decrease in perceived stress at 2-month follow-up. At postintervention, the experimental group showed a decrease in momentary negative affect compared with the pseudo-experimental and control groups. No effects were found for retrospective mastery, depression, anxiety, and momentary positive affect. CONCLUSIONS: ESM interventions could be an important asset for increasing caregiver resources and could help caregivers to better adapt and manage difficult situations and to protect against negative emotions.

Interaction between blood-brain barrier and glymphatic system in solute clearance.

Neurovascular pathology concurs with protein accumulation, as the brain vasculature is important for waste clearance. Interstitial solutes, such as amyloid-ß, were previously thought to be primarily cleared from the brain by blood-brain barrier transport. Recently, the glymphatic system was discovered, in which cerebrospinal fluid is exchanged with interstitial fluid, facilitated by the aquaporin-4 water channels on the astroglial endfeet. Glymphatic flow can clear solutes from the interstitial space. Blood-brain barrier transport and glymphatic clearance likely serve complementary roles with partially overlapping mechanisms providing a well-conditioned neuronal environment. Disruption of these mechanisms can lead to protein accumulation and may initiate neurodegenerative disorders, for instance amyloid-ß accumulation and Alzheimer's disease. Although both mechanisms seem to have a similar purpose, their interaction has not been clearly discussed previously. This review focusses on this interaction in healthy and pathological conditions. Future health initiatives improving waste clearance might delay or even prevent onset of neurodegenerative disorders. Defining glymphatic flow kinetics using imaging may become an alternative way to identify those at risk of Alzheimer's disease.

Anxiety disorders and figural fluency: A measure of executive function.

BACKGROUND: Anxiety possibly interferes with executive functioning, although most studies rely on anxiety symptoms or lack control for comorbid depression. The objective of the present study is to examine the association between executive functioning and (individual) anxiety disorders with ak,ld without controlling for depression. METHOD: Generalized anxiety disorder (GAD), panic disorder with and without agoraphobia, agoraphobia, social phobia, as well as depressive disorder according to DSM-IV criteria were assessed with the Mini International Neuropsychiatric Interview in 82,360 community-dwelling people participating in the Lifelines cohort. Figural fluency as a measure of executive functioning was assessed with the Ruff Figural Fluency Test (RFTT). Linear regression analyses with the RFFT score as the dependent variable and psychiatric diagnosis as independent variables (dummies) were performed, adjusted for potential confounders. Multivariate results are presented with and without adjustment for depression. RESULTS: Presence of any anxiety disorder was associated with worse performance on the RFFT (B = - 0.78, SE = 0.32, p = .015), independent of depression. No dose-response relationship with the number of anxiety disorders was found. Only agoraphobia and generalized anxiety disorder were significantly associated with the RFFT score in the multivariate models. Agoraphobia remained significant when further adjusted for depressive disorder (B = - 1.14, SE = 0.41, p < .01), while GAD did not (B = 0.013, SE = 0.431, p = .975). LIMITATIONS: Executive function was tested by only one measure, namely figural fluency. CONCLUSION: Agoraphobia is associated with worse executive functioning. Treatment of agoraphobia could be influenced by the executive dysfunction which clinicians should be aware of when regular treatment fails.

The use of an electronic clinical rule to discontinue chronically used benzodiazepines and related Z drugs.

PURPOSE: The chronic use of benzodiazepines and benzodiazepine-related drugs (BZ/Z) in older people is common and not without risks. The objective of this study was to evaluate whether the implementation of a clinical rule promotes the discontinuation of chronically used BZ/Z for insomnia. METHODS: A clinical rule, generating an alert in case of chronic BZ/Z use, was created and applied to the nursing home (NH) setting. The clinical rule was a one-off intervention, and alerts did not occur over time. Reports of the generated alerts were digitally sent to NH physicians with the advice to phase out and eventually stop the BZ/Z. In cases where the advice was adopted, a follow-up period of 4 months on the use of BZ/Z was taken into account in order to determine whether the clinical rule alert led to a successful discontinuation of BZ/Z. RESULTS: In all, 808 NH patients were screened. In 161 (19.1%) of the patients, BZ/Z use resulted in a clinical rule alert. From these, the advice to phase out and stop the BZ/Z was adopted for 27 patients (16.8%). Reasons for not following the advice consisted of an unsuccessful attempt in the past (38 patients), patients family and/or patient resistance (37 patients), the non-continuous use of BZ/Z (32 patients) and indication still present (27 patients). Of the 12 NH physicians, seven adopted the advice. CONCLUSIONS: The success rate of a clinical rule for discontinuation of chronically used BZ/Z for insomnia was low, as reported in the present study. Actions should be taken to help caregivers, patients and family members understand the importance of limiting BZ/Z use to achieve higher discontinuation rates.

Well-being of nursing staff on specialized units for older patients with combined care needs.

WHAT IS ALREADY KNOWN ABOUT THE SUBJECT: Working in long-term care is seen as a stressful, physically and mentally demanding occupation, and thus, nursing staff are at risk for work and stress-related diseases. In older patients, psychiatric illnesses often occur in combination with physical illnesses, requiring nursing care that is specific to these combined care needs. The impact of caring for these patients on the mental well-being of nurses is unknown. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE: Nursing staff working on specialized units for patients with combined care needs experience high levels of self-efficacy in combination with strong feelings of self-rated competence. Although levels of burnout are relatively low, mental healthcare nursing staff is more at risk for burnout when working in specialized settings for patients with combined care needs than nursing home staff working in specialized settings for these patients. Nursing staff characteristics, such as years of working experience and age, seem more important in relation to staff well-being than patient characteristics in specialized settings for combined care needs. WHAT ARE THE IMPLICATIONS FOR PRACTICE: Staff well-being might benefit from specializing care, so that patients with similar care needs are placed together and care is focused. The presence of specialized care units for older patients with combined care needs can allow for both targeted and focused allocation of nursing staff to these units and provision of specific training. ABSTRACT: Introduction In older patients, psychiatric illnesses frequently exist in tandem with physical illnesses, requiring nursing care that is specific to these combined care needs. The impact of caring for these patients on the mental well-being of nursing staff is unknown. AIM: To investigate whether care characteristics of patients with combined care needs are related to the mental well-being of nursing staff. METHOD: Well-being of nursing staff was studied within a larger exploratory observational cross-sectional study that examined the differences and similarities of specialized combined care units in Dutch mental healthcare and nursing home settings. RESULTS: Nursing staff across settings, with more than 5 years of work experience, felt competent in caring for patients with combined care needs. No significant effects of care characteristics of patients with combined care needs on the work-related well-being of nursing staff were shown. Both mental health nursing staff and older employees, however, were found to be more at risk for burnout. IMPLICATIONS/CONCLUSION: Staff well-being might benefit from placing patients with combined care needs together, so care is focused. The presence of specialized care units can allow for both targeted and focused allocation of nursing staff to these units and provision of specific training.

Behavior and Evolution of Young ONset Dementia part 2 (BEYOND-II) study: an intervention study aimed at improvement in the management of neuropsychiatric symptoms in institutionalized people with young onset dementia.

ABSTRACTBackground:Both neuropsychiatric symptoms (NPS) and psychotropic drug use (PDU) are common in institutionalized People with Young Onset Dementia (PwYOD) and can produce negative outcomes such as reduced quality of life and high workload. In community-dwelling PwYOD, NPS are found to be associated with unmet care needs. This emphasizes the importance of a care program for the management of NPS in institutionalized PwYOD that also addresses unmet care needs and PDU. The objectives of the Behavior and Evolution of Young ONset Dementia part 2 (BEYOND-II) study are to develop a care program for the management of NPS in institutionalized PwYOD and to evaluate its effectiveness. METHODS: The care program consists of an educational program combined with an intervention to manage NPS with the following five steps: the evaluation of psychotropic drug prescription, detection, analysis (including the detection of unmet needs), treatment and the evaluation of NPS. A stepped wedge design will be used to evaluate its effectiveness. The primary outcomes are agitation and aggression and other NPS. The secondary outcomes are PDU, quality of life, the workload of nursing staff and job satisfaction. Additionally, a process analysis and a cost-consequence analysis will be conducted. CONCLUSIONS: The study protocol of the Beyond-II study describes the development, implementation and evaluation of a care program for the management of NPS in institutionalized PwYOD. This care program provides a structured method for the management of NPS, in which unmet needs and PDU are also addressed.

Development of prediction models for upper and lower respiratory and gastrointestinal tract infections using social network parameters in middle-aged and older persons -The Maastricht Study.

The ability to predict upper respiratory infections (URI), lower respiratory infections (LRI), and gastrointestinal tract infections (GI) in independently living older persons would greatly benefit population and individual health. Social network parameters have so far not been included in prediction models. Data were obtained from The Maastricht Study, a population-based cohort study (N = 3074, mean age (±s.d.) 59.8 ± 8.3, 48.8% women). We used multivariable logistic regression analysis to develop prediction models for self-reported symptomatic URI, LRI, and GI (past 2 months). We determined performance of the models by quantifying measures of discriminative ability and calibration. Overall, 953 individuals (31.0%) reported URI, 349 (11.4%) LRI, and 380 (12.4%) GI. The area under the curve was 64.7% (95% confidence interval (CI) 62.6-66.8%) for URI, 71.1% (95% CI 68.4-73.8) for LRI, and 64.2% (95% CI 61.3-67.1%) for GI. All models had good calibration (based on visual inspection of calibration plot, and Hosmer-Lemeshow goodness-of-fit test). Social network parameters were strong predictors for URI, LRI, and GI. Using social network parameters in prediction models for URI, LRI, and GI seems highly promising. Such parameters may be used as potential determinants that can be addressed in a practical intervention in older persons, or in a predictive tool to compute an individual's probability of infections.

Pericortical Enhancement on Delayed Postgadolinium Fluid-Attenuated Inversion Recovery Images in Normal Aging, Mild Cognitive Impairment, and Alzheimer Disease.

BACKGROUND AND PURPOSE: Breakdown of BBB integrity occurs in dementia and may lead to neurodegeneration and cognitive decline. We assessed whether extravasation of gadolinium chelate could be visualized on delayed postcontrast FLAIR images in older individuals with and without cognitive impairment. MATERIALS AND METHODS: Seventy-four individuals participated in this study (15 with Alzheimer disease, 33 with mild cognitive impairment, and 26 with normal cognition). We assessed the appearance of pericortical enhancement after contrast administration, MR imaging markers of cerebrovascular damage, and medial temporal lobe atrophy. Three participants who were positive for pericortical enhancement (1 with normal cognition and 2 with mild cognitive impairment) were followed up for approximately 2 years. In vitro experiments with a range of gadolinium concentrations served to elucidate the mechanisms underlying the postcontrast FLAIR signals. RESULTS: Postcontrast pericortical enhancement was observed in 21 participants (28%), including 6 individuals with Alzheimer disease (40%), 10 with mild cognitive impairment (30%), and 5 with normal cognition (19%). Pericortical enhancement was positively associated with age (P < .02) and ischemic stroke (P < .05), but not with cognitive status (P = .3). Foci with enhanced signal remained stable across time in all follow-up cases. The in vitro measurements confirmed that FLAIR imaging is highly sensitive for the detection of low gadolinium concentrations in CSF, but not in cerebral tissue. CONCLUSIONS: Postcontrast pericortical enhancement on FLAIR images occurs in older individuals with normal cognition, mild cognitive impairment, and dementia. It may represent chronic focal superficial BBB leakage. Future longitudinal studies are needed to determine its clinical significance.

Obesity and Cognitive Decline in Adults: Effect of Methodological Choices and Confounding by Age in a Longitudinal Study.

BACKGROUND AND OBJECTIVES: Obesity has been associated with increased risk of cognitive impairment or dementia, but recent findings are contradictory, possibly due to methodological differences. The present study tries to clarify these inconsistencies by following the cognitive trajectories of individuals with obesity over 12 years and studying the effect of obesity status (obesity at baseline versus incident obesity at follow-up), chronicity, definition, potential confounding (e.g. age, cardiovascular factors), and non-linear associations. DESIGN: Longitudinal study with 12 years follow-up. SETTING: Community based. PARTICIPANTS: 1,807 cognitively healthy individuals (aged 24-83) from the Maastricht Aging Study (1992-2004). MEASUREMENTS: Memory, executive function and processing speed were assessed at baseline and at 6- and 12-year follow-up. Obesity was defined as having a body mass index (BMI) of ≥ 30.0 kg/m2 or waist circumference (WC) of > 102 cm for men and > 88 cm for women. RESULTS: At baseline, 545 persons were obese (BMI: 329 (18%); WC: 494 (27%); both: 278 (15%). They showed faster decline in memory, executive function, and processing speed. Chronic obese showed less widespread impairment than those who regained normal weight. Associations across cognitive domains were weaker for obesity defined by BMI than for WC. At follow-up, 190 developed obesity, and they performed worse on executive function at baseline, but showed less decline compared with participants with normal weight. Yet, age-stratification and post-hoc analyses showed that most of these associations were confounded by age. CONCLUSIONS: This study shows that the association between obesity and cognitive decline was confounded by the effect of age on rate of decline. Future studies should take this into account.

A first step toward integrating schema theory in geriatric psychiatry: a Delphi study.

BACKGROUND: Schematherapy (ST) is an effective therapy for personality disorders (PD's) in adults, however, empirical research into ST in older adults is limited. The manifestation of schemas over the life course is unclear. Besides, long-term patterns of schemas in old age and whether schemas change during the aging process remain unknown. METHODS: We performed a Delphi study involving a group meeting of nine experts in the field of ST in older adults. RESULTS: Full consensus was achieved that schemas vary later in life, and that this is due to biopsychosocial factors. The concepts of schema triggering (the chance that a maladaptive schema is activated) and schema coping (the psychological and behavioral effort a person makes to minimize the stress that comes with the schema) in the past are important in clinical practice. Understanding how schemas are triggered during the life course and how patients deal with their schemas throughout life will help the therapist to complete the diagnostic puzzle in older individuals and to choose appropriate interventions. CONCLUSION: Schemas are flexible and dynamic constructs that can fade or intensify due to multiple factors. This study is a first step toward advancing the state of knowledge regarding schema theory in an aging population. The results will contribute to improvements in ST in older adults by developing an understanding of the plasticity of schemas during the life course.

Dealing with daily challenges in dementia (deal-id study): an experience sampling study to assess caregiver functioning in the flow of daily life.

OBJECTIVE: Accurate assessment of caregiver functioning is of great importance to gain better insight into daily caregiver functioning and to prevent high levels of burden. The experience sampling methodology (ESM) is an innovative approach to assess subjective experiences and behavior within daily life. In this study, the feasibility of the ESM in spousal caregivers of people with dementia was examined, and the usability of ESM data for clinical and scientific practice was demonstrated. METHODS: Thirty-one caregivers collected ESM data for six consecutive days using an electronic ESM device that generated ten random alerts per day. After each alert, short reports of the caregiver's current mood state and context were collected. Feasibility was assessed by examining compliance and subjective experiences with the ESM. Usability was described using group and individual ESM data. RESULTS: Participants on average completed 78.8% of the reports. One participant completed less than 33% of the reports and was excluded from data analyses. Participants considered the ESM device to be a user-friendly device in which they could accurately describe their feelings and experiences. The ESM was not experienced as too burdensome. Zooming in on the ESM data, personalized patterns of mood and contextual factors were revealed. CONCLUSIONS: The ESM is a feasible method to assess caregiver functioning. In addition to standard retrospective measurements, it offers new opportunities to gain more insight into the daily lives of people with dementia and their caregivers. It also provides new possibilities to tailor caregiver support interventions to the specific needs of the caregiver. Copyright © 2016 John Wiley & Sons, Ltd.

[An 87-year-old-man with late-onset frontotemporal dementia: a case-study]. / Een 87-jarige man met late-onset frontotemporale dementie.

An 87-year-old man showed behavioral disinhibition and nocturnal restlessness as well as short-term memory problems. We diagnosed late-onset frontotemporal dementia (LO-FTD), a relatively rare disease. Based on the course of the disease progress, we ruled out medication-induced mania and bipolar disorder. Given the results of the CT-scan, we also dismissed the possibility that the patient was suffering from dementia based on Alzheimer's disease and vascular factors that followed an atypical course. Our article illustrates the complexity of the diagnostic process investigating LO-FTD.

Lower verbal intelligence is associated with diabetic complications and slower walking speed in people with Type 2 diabetes: the Maastricht Study.

AIMS: To determine the association of verbal intelligence, a core constituent of health literacy, with diabetic complications and walking speed in people with Type 2 diabetes. METHODS: This study was performed in 228 people with Type 2 diabetes participating in the Maastricht Study, a population-based cohort study. We examined the cross-sectional associations of score on the vocabulary test of the Groningen Intelligence Test with: 1) determinants of diabetic complications (HbA1c , blood pressure and lipid level); 2) diabetic complications: chronic kidney disease, neuropathic pain, self-reported history of cardiovascular disease and carotid intima-media thickness; and 3) walking speed. Analyses were performed using linear regression and adjusted in separate models for potential confounders and mediators. Significant age- and sex-adjusted associations were additionally adjusted for educational level in a separate model. RESULTS: After full adjustment, lower verbal intelligence was associated with the presence of neuropathic pain [odds ratio (OR) 1.18, 95% CI 1.02;1.36], cardiovascular disease (OR 1.14, 95% CI 1.01;1.30), and slower walking speed (regression coefficient -0.011 m/s, 95% CI -0.021; -0.002 m/s). These associations were largely explained by education. Verbal intelligence was not associated with blood pressure, glycaemic control, lipid control, chronic kidney disease or carotid intima-media thickness. CONCLUSIONS: Lower verbal intelligence was associated with the presence of some diabetic complications and with a slower walking speed, a measure of physical functioning. Educational level largely explained these associations. This implies that clinicians should be aware of the educational level of people with diabetes and should provide information at a level of complexity tailored to the patient.

Co-Presence of Multimorbidity and Disability with Frailty: An Examination of Heterogeneity in the Frail Older Population.

BACKGROUND: Frailty is often associated with multimorbidity and disability. OBJECTIVES: We investigated heterogeneity in the frail older population by characterizing five subpopulations according to quantitative biological markers, multimorbidity and disability, and examined their association with mortality and nursing home admission. DESIGN: Observational study. PARTICIPANTS: Participants (n=4,414) were from the population-based Age Gene/Environment Susceptibility Reykjavik Study. MEASUREMENTS: Frailty was defined by ≥ 3 of five characteristics: weight loss, weakness, reduced energy levels, slowness and physical inactivity. Multimorbidity was assessed using a simple disease count, based on 13 prevalent conditions. Disability was assessed by five activities of daily living; participants who had difficulty with one or more tasks were considered disabled. Differences among frail subpopulations were based on the co-presence of multimorbidity and disability. Differences among the following subpopulations were examined: 1) Non-frail (reference group); 2) Frail only; 3) Frail with disability; 4) Frailty with multimorbidity; 5) Frail with disability and multimorbidity. RESULTS: Frailty was present in 10.7% (n=473). Frailty was associated with increased risk for mortality (OR 1.40; 95% CI 1.15-1.69) and nursing home admission (OR 1.50; 95% CI 1.16-1.93); risks differed by subpopulations. Compared to the non-frail, the frail only group had poorer cognition and increased inflammation levels but did not have increased risk for mortality (OR 1.40; 95% CI 0.84-2.33) or nursing home admission (OR 1.01; 95% CI 0.46-2.21). Compared to the non-frail, the other frail subpopulations had significantly poorer cognition, increased inflammation levels, more white matter lesions, higher levels of calcium, glucose and red cell distribution width and increased risk for mortality and nursing home admission. CONCLUSIONS: The adverse health risks associated with frailty in the general older adult population may primarily be driven by increased disease burden and disability.

Associations of advanced glycation end-products with cognitive functions in individuals with and without type 2 diabetes: the maastricht study.

CONTEXT: Advanced glycation end-products (AGEs) are thought to be involved in the pathogenesis of Alzheimer's disease. AGEs are products resulting from nonenzymatic chemical reactions between reduced sugars and proteins, which accumulate during natural aging, and their accumulation is accelerated in hyperglycemic conditions such as type 2 diabetes mellitus. OBJECTIVE: The objective of the study was to examine associations between AGEs and cognitive functions. DESIGN, SETTING, AND PARTICIPANTS: This study was performed as part of the Maastricht Study, a population-based cohort study in which, by design, 215 participants (28.1%) had type 2 diabetes mellitus. MAIN OUTCOME MEASURES: We examined associations of skin autofluorescence (SAF) (n = 764), an overall estimate of skin AGEs, and specific plasma protein-bound AGEs (n = 781) with performance on tests for global cognitive functioning, information processing speed, verbal memory (immediate and delayed word recall), and response inhibition. RESULTS: After adjustment for demographics, diabetes, smoking, alcohol, waist circumference, total cholesterol/high-density lipoprotein cholesterol ratio, triglycerides, and lipid-lowering medication use, higher SAF was significantly associated with worse delayed word recall (regression coefficient, b = -0.44; P = .04), and response inhibition (b = 0.03; P = .04). After further adjustment for systolic blood pressure, cardiovascular disease, estimated glomerular filtration rate, and depression, associations were attenuated (delayed word recall, b = -0.38, P = .07; response inhibition, b = 0.02, P = .07). Higher pentosidine levels were associated with worse global cognitive functioning (b = -0.61; P = .04) after full adjustment, but other plasma AGEs were not. Associations did not differ between individuals with and without diabetes. CONCLUSION: We found inverse associations of SAF (a noninvasive marker for tissue AGEs) with cognitive performance, which were attenuated after adjustment for vascular risk factors and depression.

Characteristics of institutionalized young onset dementia patients--the BEYOnD study.

BACKGROUND: People with Young Onset Dementia (YOD) have specific needs for care. These people eventually require institutional care, usually delivered by institutions designed for the elderly. The Dutch network of care organizations delivering specialized YOD care offers a unique opportunity to obtain more knowledge of this special population. METHODS: Our cross-sectional study collected data from 230 people with YOD in eight care homes providing YOD specialized care. Data collected: demographic data, disease duration, dementia subtype, comorbidity, dementia severity (Global Deterioration Scale - GDS), neuropsychiatric symptoms (NPS; Neuropsychiatric Inventory - NPI, Cohen Mansfield Agitation Inventory - CMAI), disease awareness (Guidelines for the Rating of Awareness Deficits - GRAD), need for assistance (hierarchic Activities of Daily Living (ADL) scale - Resident Assessment Instrument - Minimum Data Set (RAI-MDS)). RESULTS: The mean age of the residents with YOD in care homes was 60 years and 53% of them were men. There is a large variety of etiologic diagnoses underlying the dementia. Dementia severity was very mild to mild in 18%, moderate in 25%, and severe or very severe in 58% of the participants. The prevalence of NPS was high with 90% exhibiting one or more clinically relevant NPS. Comorbidity was present in more than three quarters of the participants, most frequently psychiatric disorders. CONCLUSIONS: The institutionalized YOD population is heterogeneous. NPS occur in almost all institutionalized people with YOD, and frequency and severity of NPS are higher than in late onset dementia (LOD) and community-dwelling YOD patients. Care should be delivered in settings accommodating a mixed male and female population, with appropriate, meaningful activities for all individuals. Further research is needed on NPS in YOD, to enhance quality of life and work in specialized YOD-care.

A systematic review of Internet-based supportive interventions for caregivers of patients with dementia.

OBJECTIVE: Because of the expected increase in the number of dementia patients, the unlikelihood of a cure in the near future, and the rising cost of care, there is an increasing need for effective caregiver interventions. Internet interventions hold considerable promise for meeting the educational and support needs of informal dementia caregivers at reduced costs. The current study aims to provide an overview of the evidence for the effectiveness, feasibility, and quality of Internet interventions for informal caregivers of people with dementia. METHODS: A systematic literature search of five scientific databases was performed, covering literature published up to 10 January 2013. Twelve studies were identified. The quality of the included studies was assessed according to the Cochrane level of evidence and the criteria list of the Cochrane Back Review Group. RESULTS: The intervention types, dosage, and duration differed widely, as did the methodological quality of the included studies. The overall level of evidence was low. However, the results demonstrate that Internet interventions for informal dementia caregivers can improve various aspects of caregiver well-being, for example, confidence, depression, and self-efficacy, provided they comprise multiple components and are tailored to the individual. Furthermore, caregivers could benefit from interaction with a coach and other caregivers. CONCLUSIONS: Internet interventions for informal dementia caregivers may improve caregiver well-being. However, the available supporting evidence lacks methodological quality. More randomized controlled studies assessing interventions performed according to protocol are needed to give stronger statements about the effects of supportive Internet interventions and their most promising elements.

Systematic review and collaborative recalculation of 133,693 incident cases of schizophrenia.

BACKGROUND: This systematic review and collaborative recalculation was set up to recalculate schizophrenia incidence rates from previously published studies by age and sex. METHOD: PubMed, EMBASE and PsycINFO databases were searched (January 1950 to December 2009) for schizophrenia incidence studies. Numerator and population data were extracted by age, sex and, if possible, study period. Original data were requested from the authors to calculate age- and sex-specific incidence rates. Incidence rate ratios (IRRs) with their 95% confidence intervals (CIs) were computed by age and sex from negative binomial regression models. RESULTS: Forty-three independent samples met inclusion criteria, yielding 133 693 incident cases of schizophrenia for analysis. Men had a 1.15-fold (95% CI 1.00-1.31) greater risk of schizophrenia than women. In men, incidence peaked at age 20-29 years (median rate 4.15/10,000 person-years, IRR 2.61, 95% CI 1.74-3.92). In women, incidence peaked at age 20-29 (median rate 1.71/10,000 person-years, IRR 2.34, 95% CI 1.66-3.28) and 30-39 years (median rate 1.24/10,000 person-years, IRR 2.25, 95% CI 1.55-3.28). This peak was followed by an age-incidence decline up to age 60 years that was stronger in men than in women (χ² = 57.90, p < 0.001). The relative risk of schizophrenia was greater in men up to age 39 years and this reversed to a greater relative risk in women over the age groups 50-70 years. No evidence for a second incidence peak in middle-aged women was found. CONCLUSIONS: Robust sex differences exist in the distribution of schizophrenia risk across the age span, suggesting differential susceptibility to schizophrenia for men and women at different stages of life.
