Patients with moderate to severe dementia commonly exhibit agitation and aggression in response to personal care. Incident pain is a common factor underlying response agitation that in turn can obstruct the delivery of essential nursing care. Medications commonly used to manage response agitation have specific risks in patients with dementia. This report details the case of a patient suffering from severe dementia with incident pain and response agitation that remitted with the use of sublingual sufentanil, a rapid-onset and ultra-brief acting opioid analgesic.

Caregiving experiences in dementia may have adverse effects on the caregiver's own physical and mental health. The Zarit Burden Interview (ZBI) is the most widely used instrument for assessing family carer burden and the purpose of the present study was to evaluate the psychometric properties of the Italian version of the ZBI (I-ZBI). ⋯ The Italian version of the Zarit Burden Interview is valid, reliable and useful for use in clinical contexts and in future studies that could lead to a better understanding of carer burden in dementia. Clarifying the factorial structure of the ZBI would help to further the understanding of the large body of research using it and would also help to advance the understanding of subjective burden.

Comparative Study
Case finding in dementia: comparative utility of three brief instruments in the memory clinic setting.
The principal goal of this study was to compare the diagnostic accuracy of three brief instruments in memory clinic attendees. Two of the instruments were based on face-to-face clinical assessment (Standardized Mini-mental State Examination and Rowland Universal Dementia Assessment Scale), whereas the third group used proxy information from an informant (Informant Questionnaire on Cognitive Decline in the Elderly). Dementia diagnosis as provided by a specialist physician (geriatrician, psychiatrist or neurologist) was used as the reference standard. ⋯ Diagnostic accuracy was similar for the three instruments, which all proved to be moderately useful tools for initial screening for cognitive impairment in the memory clinic environment. Being a proxy measure, the IQCODE had specific practical use in this context, where the patient might not be able to provide information. The RUDAS exhibited high specificity and proved to be less dependent upon cultural factors than the SMMSE, making it particularly valuable in a multicultural setting.

Previous studies have reported that nurse detection of delirium has low sensitivity compared to a research diagnosis. As yet, no study has examined the use of nurse-observed delirium symptoms combined with research-observed delirium symptoms to diagnose delirium. Our specific aims were: (1) to describe the effect of using nurse-observed symptoms on the prevalence of delirium symptoms and diagnoses in long-term care (LTC) facilities, and (2) to compare the predictive validity of delirium diagnoses based on the use of research-observed symptoms alone with those based on research-observed and nurse-observed symptoms. ⋯ The inclusion of delirium symptoms observed by nurses not only increases the detection of delirium in LTC facilities but improves the prediction of outcomes.
