The Roth Project - Music and Memory: A Community Agency Initiated Individualized Music Intervention for People with Dementia.

INTRODUCTION: "The Roth Project - Music and Memory" is a music-based intervention program, implemented by the Alzheimer's Association of Central and Western Kansas, which provides a non-pharmacological means for addressing neuropsychiatric symptoms in individuals with dementia. METHODS: Participants were individuals with dementia who were enrolled in The Roth Project - Music and Memory. Post-intervention surveys were distributed to caregivers of participants which assessed caregiver satisfaction with the program as well as caregiver perception of the impact of individualized music on mood and behavioral symptoms. RESULTS: Of returned surveys (n = 79), 99% of caregivers indicated they were satisfied or very satisfied with the program and 94% of caregivers perceived participants to like or very much like listening to the music. While a substantial number of participants required assistance with iPod use (95%), the majority of participants were observed to listen to the music with stable or increased frequency over time. Personalized music was observed to improve mood in 78% of cases, with the most frequent benefits being improved overall happiness, decreased anxiety, increased positive emotional expression, and decreased depression. CONCLUSIONS: The Roth Project - Music and Memory was well received by caregivers and was perceived to benefit mood of individuals with dementia. These results provided ongoing support for individualized music-based interventions and demonstrated that such interventions, when implemented by community agencies, can be well received by those who use them.

Effects of Delay Duration on the WMS Logical Memory Performance of Older Adults with Probable Alzheimer's Disease, Probable Vascular Dementia, and Normal Cognition.

OBJECTIVE: To examine how the duration of time delay between Wechsler Memory Scale (WMS) Logical Memory I and Logical Memory II (LM) affected participants' recall performance. METHOD: There are 46,146 total Logical Memory administrations to participants diagnosed with either Alzheimer's disease (AD), vascular dementia (VaD), or normal cognition in the National Alzheimer's Disease Coordinating Center's Uniform Data Set. RESULTS: Only 50% of the sample was administered the standard 20-35 min of delay as specified by WMS-R and WMS-III. We found a significant effect of delay time duration on proportion of information retained for the VaD group compared to its control group, which remained after adding LMI raw score as a covariate. There was poorer retention of information with longer delay for this group. This association was not as strong for the AD and cognitively normal groups. A 24.5-min delay was most optimal for differentiating AD from VaD participants (47.7% classification accuracy), an 18.5-min delay was most optimal for differentiating AD versus normal participants (51.7% classification accuracy), and a 22.5-min delay was most optimal for differentiating VaD versus normal participants (52.9% classification accuracy). CONCLUSIONS: Considering diagnostic implications, our findings suggest that test administration should incorporate precise tracking of delay periods. We recommend a 20-min delay with 18-25-min range. Poor classification accuracy based on LM data alone is a reminder that story memory performance is only one piece of data that contributes to complex clinical decisions. However, strict adherence to the recommended range yields optimal data for diagnostic decisions.
