Randomized Controlled Trial Multicenter StudyEfficacy of memantine in PDD and DLB: an extension study including washout and open-label treatment.
This 30-week extension trial was a continuation of the first double-blind randomized controlled trial (RCT) to study memantine in dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD). The objective was to evaluate the presence of recurrence of symptoms upon drug withdrawal. Furthermore, the aim was to explore washout dynamics in order to inform clinical practice. ⋯ The findings inform clinical practice that any possible memantine-associated benefits might be rapidly lost after drug withdrawal. The magnitude of deterioration suggests a symptomatic rather than a disease-modifying effect of the drug. Open-label results should merely be considered inspiration for future trials.

The utility of PAINAD in assessing pain in a UK population with severe dementia.
Studies suggest that pain is under-recognized and under-treated in those with severe dementia. Identifying pain is the first step in its effective management. Few studies have investigated the utility of behavioural pain tools in those with advanced dementia. ⋯ PAINAD is a sensitive tool for detecting pain in people with advanced dementia, but has a high false positive rate, frequently detecting psychosocial distress rather than pain. PAINAD can be used to assess whether pain management strategies have been successful.

Assessing neuropsychiatric symptoms in nursing home patients with dementia: reliability and Reliable Change Index of the Neuropsychiatric Inventory and the Cohen-Mansfield Agitation Inventory.
The aim of the study was to estimate inter-observer and test-retest reliability of the Neuropsychiatric Inventory Nursing Home version (NPI-NH) and the Cohen-Mansfield Agitation Inventory (CMAI), and to establish their Reliable Change Index (RCI). Reliable Change methodology is a practical method for estimating the least change acquired in outcome measures. ⋯ Reliability estimates and RCI for the NPI-NH were modest, seriously challenging its reliability and sensitivity to change over time. NPI-NH may only be useful for monitoring behavioral changes in individual patients with dementia, when symptoms are moderate to severe, or when effect sizes are large. Reliability of the CMAI was good, supporting its usefulness in clinical practice. Poor inter-observer agreement on behavioral observations poses a real challenge in nursing homes. Reliable scales are needed that include unambiguously formulated items.
