Abstract: Despite much recent interest in music and dementia, music perception has not been widely studied across dementia syndromes using an information processing approach. We designed a novel neuropsychological battery to assess perception of musical patterns in the dimensions of pitch and temporal information requiring detection of notes that deviated from the established pattern based on … local or global sequence features and musical scene analysis requiring detection of a familiar tune within polyphonic harmony.
Performance on these tests was referenced to generic auditory timbral deviance detection and recognition of familiar tunes and adjusted for general auditory working memory performance. Relative to healthy controls, patients with AD and LPA had group-level deficits of global pitch melody contour processing while patients with PNFA as a group had deficits of local interval as well as global pitch processing. There was substantial individual variation within syndromic groups. Taking working memory performance into account, no specific deficits of musical temporal processing, timbre processing, musical scene analysis, or tune recognition were identified.
The findings suggest that particular aspects of music perception such as pitch pattern analysis may open a window on the processing of information streams in major dementia syndromes. The potential selectivity of musical deficits for particular dementia syndromes and particular dimensions of processing warrants further systematic investigation. Objective: To assess the association between plasma Hcy level and real-space navigation performance and the role of vascular risk and protective factors, APOE status, and white matter lesions WML on this association.
Methods: Ninety-two non-demented older adults 29 with amnestic mild cognitive impairment, 46 with subjective cognitive decline, and 17 cognitively normal older adults underwent spatial navigation testing of egocentric, allocentric, and mixed navigation in a real-space analogue of the Morris water maze, … neuropsychological examination, blood collection, and MRI brain scan with evaluation of WML. High total cholesterol and low vitamin B12 and folate levels increased the adverse effect of Hcy on egocentric and mixed navigation.
WML did not explain the association between plasma Hcy level and navigation performance. Conclusion: Elevated plasma Hcy level may affect real-space navigation performance above and beyond vascular brain changes. This association may be magnified in the presence of high total cholesterol and low folate or vitamin B12 levels.
Attention to the level of plasma Hcy may be a viable intervention strategy to prevent decline in spatial navigation in non-demented older adults. Chabot, Julia Levinoff, Elise J. Allali, Gilles. Abstract: Background: Increased stride time variability has been associated with memory impairment in mild cognitive impairment.
The association between increased stride time variability and SMI has not been reported. Objective: This study aims to examine the association of stride time variability while performing single and dual tasking with SMI in cognitively healthy individuals CHI. The coefficient of variation CoV of stride time and walking speed were recorded under usual condition and while counting backwards. Age, gender, body mass index, number of drugs taken daily, use of psychoactive drugs, fear of falling, history of previous falls, and walking speed were used as covariates.
Thus, gait variability under dual-task in individuals with SMI expressed by their relatives can be a potential biomarker of AD.
