[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.

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.

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.

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.

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.

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.

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.

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.

[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.

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.

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.

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.

Anxiety is related to Alzheimer cerebrospinal fluid markers in subjects with mild cognitive impairment.

BACKGROUND: Anxiety, apathy and depression are common in subjects with mild cognitive impairment (MCI) and may herald Alzheimer's disease (AD). We investigated whether these symptoms correlated with cerebrospinal fluid (CSF) markers for AD in subjects with MCI. Method Subjects with MCI (n=268) were selected from the 'Development of screening guidelines and criteria for pre-dementia Alzheimer's disease' (DESCRIPA) and Alzheimer's Disease Neuroimaging Initiative (ADNI) studies. We measured amyloid ß(1-42) protein (Aß42) and total tau (t-tau) in CSF. Neuropsychiatric symptoms were measured with the Neuropsychiatric Inventory. RESULTS: Depressive symptoms were reported by 55 subjects (21%), anxiety by 35 subjects (13%) and apathy by 49 subjects (18%). The presence of anxiety was associated with abnormal CSF Aß42 [odds ratio (OR) 2.3, 95% confidence interval (CI) 1.6-3.3] and t-tau (OR 2.6, 95% CI 1.9-3.6) concentrations and with the combination of abnormal concentrations of both Aß42 and t-tau (OR 3.1, 95% CI 2.0-4.7). The presence of agitation and irritability was associated with abnormal concentrations of Aß42 (agitation: OR 1.6, 95% CI 1.1-2.3; irritability: OR 2.2, 95% CI 1.5-3.3). Symptoms of depression and apathy were not related to any of the CSF markers. CONCLUSIONS: In subjects with MCI, symptoms of anxiety, agitation and irritability may reflect underlying AD pathology, whereas symptoms of depression and apathy do not.

Time to diagnosis in young-onset dementia as compared with late-onset dementia.

BACKGROUND: The extent to which specific factors influence diagnostic delays in dementia is unclear. Therefore, the aim of the present study was to compare duration from symptom onset to diagnosis for young-onset dementia (YOD) and late-onset dementia (LOD) and to assess the effect of age at onset, type of dementia, gender, living situation, education and family history of dementia on this duration. METHOD: Data on 235 YOD and 167 LOD patients collected from caregivers from two prospective cohort studies were used. Multiple linear regression analysis was performed. RESULTS: The duration between symptom onset and the diagnosis of YOD exceeded that of LOD by an average of 1.6 years (2.8 v. 4.4 years). Young age and being diagnosed with frontotemporal dementia were related to increases in the time to diagnosis. Subjects with vascular dementia experienced shorter time to diagnosis. CONCLUSIONS: There is a need to raise special awareness of YOD to facilitate a timely diagnosis.

Effectiveness of an electronic cognitive aid in patients with acquired brain injury: a multicentre randomised parallel-group study.

The objective of the study was to examine the effectiveness of a customised personal digital assistant (PDA) as a cognitive aid for people with acquired brain injury, using a randomised parallel-group study. The participants were 34 patients with acquired brain injury in a cognitive rehabilitation setting. The experimental group used a customised PDA, while the control group received care-as-usual (paper-and-pencil aids). Measurements were conducted at baseline (T0), after 8 hours of training (T1), after 16 hours of training (T2), and at 5-month follow-up (T3). The main outcome was the attainment of individualised goals. Both groups showed a significant increase in goal attainment (GAS) (p < .001). There were no significant differences between the groups at T1 or T2 on any of the other outcome measures. It was concluded that the customised PDA was as effective as paper-and-pencil aids, and may therefore serve as a useful alternative when choosing the optimal rehabilitation strategy for a patient.

Experiences with cerebrospinal fluid analysis in Dutch memory clinics.

BACKGROUND: Evidence on cerebrospinal fluid (CSF) analysis to demonstrate Alzheimer's disease has not yet been implemented in diagnostic guidelines. METHODS: We investigated the use of CSF analysis in a survey amongst all known memory clinics in the Netherlands, of which 85 of 113 (75.2%) responded. RESULTS: Sixty per cent of respondents used CSF analysis in 5% (median) of patients. The analysis almost always confirmed the working diagnosis in 68.4% and sometimes changed it in 28.2%. Complications occurred very infrequently (0%, median) and were mild. Reasons not to perform CSF analysis included the lack of clear recommendations in diagnostic guidelines. CONCLUSIONS: These results ask for a guideline update to clarify the use of CSF analysis as an add-on diagnostic method.

Brain-specific fatty acid-binding protein is elevated in serum of patients with dementia-related diseases.

BACKGROUND: There is a need for biomarkers in accessible matrices, such as blood, for the diagnosis of neurodegenerative diseases. The aim of this study was to measure the serum levels of brain-type fatty acid-binding protein (FABP) and heart-type FABP in patients with dementia-involving diseases. METHODS: Brain- and heart-type FABP were measured in serum samples from patients with either Alzheimer's disease (AD) (n = 31), Parkinson's disease (PD, n = 43), or other cognitive disorders (OCD, n = 42) and in 52 healthy controls. The localization of brain- and heart-type FABP was determined in brain sections by immunohistochemistry. RESULTS: Brain-type FABP levels were elevated in serum of 29%, 35%, and 24% of the patients with AD, PD, and OCD, respectively, and in 2% of the healthy donors. Heart-type FABP serum levels were not different amongst the patient groups. Brain-type and heart-type FABP expression was observed in reactive astrocytes in brain sections of patients with AD. CONCLUSIONS: In contrast to heart-type FABP, serum levels of brain-type FABP are elevated in a significant proportion of patients with various neurodegenerative diseases and can therefore have importance for defining subgroups of these patients.

Regional differences in effects of APOE ε4 on cognitive impairment in non-demented subjects.

BACKGROUND: The APOE ε4 allele is a risk factor for Alzheimer's disease (AD). APOE ε4 is common in non-demented subjects with cognitive impairment. In both healthy people and people with AD, its prevalence has a north-south gradient across Europe. In the present study, we investigated whether the relation between the APOE ε4 allele and cognitive impairment varied across Northern, Middle and Southern Europe. We also investigated whether a north-south gradient existed in subjects with subjective cognitive impairment (SCI), amnestic mild cognitive impairment (MCI) and non-amnestic MCI. METHODS: Data from 16 centers across Europe were analyzed. RESULTS: A north-south gradient in APOE ε4 prevalence existed in the total sample (62.7% for APOE ε4 carriers in the northern region, 42.1% in the middle region, and 31.5% in the southern region) and in subjects with SCI and amnestic MCI separately. Only in Middle Europe was the APOE ε4 allele significantly associated with poor performance on tests of delayed recall and learning, as well as with the amnestic subtype of MCI. CONCLUSION: The APOE ε4 allele frequencies in subjects with SCI and amnestic MCI have a north-south gradient. The relation between the APOE ε4 allele and cognition is region dependent.

Influence of multimorbidity on cognition in a normal aging population: a 12-year follow-up in the Maastricht Aging Study.

OBJECTIVE: The prevalence of multimorbidity has risen considerably because of the increase in longevity and the rapidly growing number of older individuals. Today, only little is known about the influence of multimorbidity on cognition in a normal healthy aging population. The primary aim of the present study was to investigate the effect of multimorbidity on cognition over a 12-year period in an adult population with a large age range. METHODS: Data were collected as part of the Maastricht Aging Study (MAAS), a prospective study into the determinants of cognitive aging. Eligible MAAS participants (N = 1763), 24-81 years older, were recruited from the Registration Network Family Practices (RNH) which enabled the use of medical records. The association between 96 chronic diseases, grouped into 23 disease clusters, and cognition on baseline, at 6 and 12 years of follow-up, were analyzed. Cognitive performance was measured in two main domains: verbal memory and psychomotor speed. A multilevel statistical analysis, a method that respects the hierarchical data structure, was used. RESULTS: Multiple disease clusters were associated with cognition during a 12-year follow-up period in a healthy adult population. The disease combination malignancies and movement disorders multimorbidity also appeared to significantly affect cognition. CONCLUSIONS: The current results indicate that a variety of medical conditions adversely affects cognition. However, these effects appear to be small in a normal healthy aging population.

Diagnostic criteria for apathy in clinical practice.

BACKGROUND: Apathy is an important and distressing behavioural symptom in Alzheimer's disease and in various neuropsychiatric disorders. Recently, diagnostic criteria for apathy have been proposed. OBJECTIVES: In groups of patients suffering from different neuropsychiatric diseases, (i) to estimate the prevalence of patients meeting the proposed diagnostic criteria; (ii) to estimate the concurrent validity of the criteria with the neuropsychiatric inventory (NPI) apathy item; (iii) to identify the most frequently met criteria or sub-criteria in each specific neuropsychiatric disease and (iv) to estimate the inter-observer reliability of the diagnostic criteria for apathy. METHODS: This cross-sectional, multicentric, observational study was performed on 306 patients. Each of the participating centres had to check the presence of apathy according to the diagnostic criteria for apathy in consecutive patients belonging to the following diagnoses list: Alzheimer disease (AD), mixed dementia, mild cognitive impairment (MCI), Parkinson's disease (PD), Schizophrenia (DSM-IV) and major depressive episode. In addition to the clinical interview, the assessment included the Mini Mental Score Examination (MMSE) and the NPI. At the end of the visit, clinicians were required to check the diagnostic criteria for apathy. RESULTS: Using the diagnostic criteria for apathy, the frequency of apathy was of 53% in the whole population, 55% in AD, 70% in mixed dementia, 43% in MCI, 27% in PD, 53% in schizophrenia and 94% in major depressive episode. In AD, mixed dementia, MCI and PD, the NPI apathy score was significantly higher for patient fulfilling the apathy criteria. Goal-directed cognitive activity (criteria B2-Cognition) was the most frequently observed domain followed by goal-directed behaviour (criteria B1-Behaviour) and emotion (criteria B3), respectively. Inter-rater reliability was high for the overall diagnostic (κ coefficient = 0.93; p = 0.0001) and for each criteria. CONCLUSION: This study is the first one to test the diagnostic criteria for apathy in clinical practice. Results make the diagnostic criteria useful for clinical practice and research.
