Randomized Controlled Trial Multicenter StudyEffect of timed bright light treatment for rest-activity disruption in institutionalized patients with Alzheimer's disease.
Disturbances in rest-activity rhythm are prominent and disabling symptoms in Alzheimer's disease (AD). Nighttime sleep is severely fragmented and daytime activity is disrupted by multiple napping episodes. In most institutional environments, light levels are very low and may not be sufficient to entrain the circadian clock to the 24-hour day. ⋯ One hour of bright light, administered to subjects with AD either in the morning or afternoon, did not improve nighttime sleep or daytime wake compared to a control group of similar subjects. However, exposure to one-hour of bright light in either the morning or afternoon may provide sufficient additional input to the circadian pacemaker to facilitate entrainment to the 24-hour day.

Multicenter StudyThe need for a consensus in the use of assessment tools for Alzheimer's disease: the Feasibility Study (assessment tools for dementia in Alzheimer Centres across Europe), a European Alzheimer's Disease Consortium's (EADC) survey.
To ensure that all Alzheimer centres across Europe are capable of using a similar method of data collection. Information about the patient assessment tools used by each participating centre was obtained and normal clinical practice in each EADC centre was documented by collecting data from routine new patient consultation. ⋯ The most common type of cognitive decline was Alzheimer's disease followed by mild cognitive impairment and vascular dementia. CDR, GDS Reisberg, and ADL/IADL were used widely (40-50%). The NPI, geriatric depression scale and ADL (Katz, 1963) were only used in 20% of the centres. We verified large differences in the tools use in the EADC centres to evaluate patients with dementia across Europe. There is a need for a consensus in the use of assessment tools for dementia in Alzheimer's centres in Europe.

Multicenter StudyAre nursing home patients with dementia diagnosis at increased risk for inadequate pain treatment?
Mentally impaired and demented nursing home patients are at increased risk of undertreatment for pain. We wanted to examine pain assessment and complaints and pain treatment of nursing home patients according to mental state, and with special regard to treatment of patients with dementia diagnosis and cognitively impaired patients who did not have a dementia diagnosis. ⋯ A label of dementia may bias the interpretation of pain cues of demented patients, while complaints from cognitively impaired patients may be taken for granted. This may contribute to lower use of PRN medication in demented patients compared to cognitively impaired patients.
