Background In Germany, the majority of PWD live at home Caregiving is provided predominantly by informal caregivers on a voluntary basis. Dementia caregiving leads to health and emotional consequences, including greater perceived stress, depression, social isolation, poor diet, diabetes, poor overall physical health etc
Special attention Neuropsychiatric symptoms in PWD have been found to be associated with distress of informal caregivers. i.e. angry behavior is associated with caregiver depression and apathy with a deterioration of the relationship between PWD and the caregiver Neuropsychiatric symptoms were identified as one common reason for the transition of PWD into nursing care. To delay institutionalization, early service utilization of PWD living in the community has been proven to be effective.
There have been studies before, but There is limited information about the relation between symptoms, their severity, and the amount of distress they impose on the caregiver. i.e. common or frequent symptoms are not necessarily the most distressing or most predictive for caregiver depression. There is a selection bias (formal diagnosis, specialists settings) Dementia is underdiagnosed in primary care, utilisation of services is low
Objectives (a) Examine different neuropsychiatric symptoms in persons screened positive for dementia in primary care with regard to their frequency, severity, and their impact on the distress of the caregiver (b) Compare persons with and without neuropsychiatric symptoms in regard to sociodemographics, carerelated, and disease-related variables (c) Identify variables related to the presence of neuropsychiatric symptoms that may serve as indicator or moderator variables and/or provide targets for interventions.
Behavioral and neuropsychiatric symptoms Neuropsychiatric inventory (NPI, Cummings, 1997) interview by proxy on 12 dimensions of neuropsychiatric behaviors ten behavioral and two neurovegetative dimensions 1. caregiver is asked a screening question whether or not the behavioral problem is present. 2. if yes, several subquestions are asked to explore the domain in more detail. 3. Caregiver is asked to rate the frequency [rarely (1) to very often (4)] and severity [mild (1) to severe (3)] of the most aberrant behavior. The product of both scores yields the NPI score for this domain (range 1-10) 3. Caregiver is asked to rate the distress associated with this domain with not at all (0) to very severely or extremely (5). A total NPI-score as well as a total distress score can be calculated by adding the scores of each domain into one total score and divide it by the number of domains.
Statistics 2 groups are of special interest the group without any neuropsychiatric symptoms, defined as having a NPI score = 0 the group with neuropsychiatric symptoms, being defined as having a NPI score = 1 in at least one of any of the twelve dimensions. Factors associated with NPI-scores are of interest: age, gender, cognitive impairment, ADL, formal diagnosis of dementia, gender of the caregiver, relationship, and living together as predictors. N=221 cases due to missing data in at least one of assessments Multivariate linear regression with fixed effects for the GPpractices
Results: the sample
Presence and frequency of neuropsychiatric symptoms
Thyrian et al, JAD 2015 Frequency of neuropsychiatric symptoms Appetite and Eating change Sleep and Night-time behavior change Aberrant motor behavior Apathy Euphoria Disinhibition Irritability Anxiety Dysphoria/Depression Agitation/Aggression Delusions Hallucinations 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% very often often sometimes rarely symptom not present caregiver distress in 12 dimensions of the NPI, m=6.11, SD=8.1 (range 0-49); PWD=persons with dementia
Severityof neuropsychiatric symptoms
Caregiver distress (NPI-12, when symptom present) Appetite and Eating change Sleep and Night-time behavior change Aberrant motor behavior Apathy Euphoria Disinhibition Irritability Anxiety Dysphoria/Depression Agitation/Aggression Delusions Hallucinations 0% 10% 20% 30% 40% 50% 60% 70% 80% 90%100% severely to extremely moderately minimal to mildly not at all caregiver distress in 12 dimensions of the NPI, m=6.11, SD=8.1 (range 0-49); PWD=persons with dementia Thyrian et al, JAD 2015
Factors associated with neuropsychiatric symptoms
Conclusions Every third person is affected by symptoms like depression, aggression, or irritability It is a clinically relevant issue in primary care The frequency and severity was rather low And, every 5 th caregiver did not indicate distress upon presence of symptom However, every third caregiver indicated severe distress when the symptom was delusions, aggression, depression, anxiety, and disinhibition ADL is associated to neuropsychiatric symptoms ADL might be a good intervention target
Limitations Cross-sectional analysis Association not prediction longitudinal data will follow in 2016 Limited generalisabilty and comparability Specific (understudied) sample of mild to moderately impaired PWD, symptoms are likely to increase in prevalence, severity, and consequential distress sample relevant to provide early and optimum care

Antidementive drug treatment about 29% of patients screened positive for dementia received at least one antipsychotic drug 38% of these patients were not formally diagnosed with dementia Galantamine, n=8 (11.1%) Rivastigmine, n=10 (13.9%) 8.3% 2.8% 12.5% 1.4% PWD with formal diagnosis of dementia (ICD-10) PWD without formal diagnosis of dementia (ICD-10) Donepezil, n=22 (30.5%) 19.4% 11.1% 22.3% 22.3% Memantine, n=32 (44.5%) 62.5% 37.5% All antidementia drugs, n=72 (100%) 0 10 20 30 40 50 60 70 80 90 100 % Wucherer et al., JAD 2015
Eichler et al., JAD 2015 Antipsychotic drug treatment about 10% of patients screened positive for dementia received at least one antipsychotic drug - typical antipsychotics: 36% - atypical antipsychotics: 64% Promethazine 3.5% Haloperidol 4.5% Typical antipsychotics Melperon 11% Pipamperon 18% Sulpirid Quetiapin 11% 21% Atypical antipsychotics Risperidon 32% 0 2 4 6 8 10 12 14
Association between medication use and NPI-scores Overall, antipsychotics use was significantly associated with higher total NPI scores Contrary to expectations, use of antipsychotics was associated with anxiety, apathy, disinhibition, aberrant motor behavior, In contrast overall antipsychotics use was not significantly associated with a clinically higher NPI scores in the dimensions of hallucinations or delusion Use of any antidepressant, sedative, antiepileptic, or antidementive drug or use of choline-esterase inhibitors was not associated with higher total NPI scores
