Abstract
Both Alzheimer's (AD) and Parkinson's disease (PD) are often associated with memory dysfunction, but their pathophysiological underpinnings differ. The current research aimed to differentiate specific profiles of memory impairment due to AD versus PD. We used controlled learning and cued recall paradigm based on the Memory Binding Test (MBT) in 'clinically cognitively normal' controls (CN; n = 161), in patients with amnestic mild cognitive impairment due to AD (AD-aMCI; n = 50) and due to PD (PD-MCI; n = 22), and in PD with normal cognition (n = 18) as based on performance in the neuropsychological battery to prevent circularity in diagnostic decision-making. We applied analysis of covariance (ANCOVA) and Receiver Operating Characteristic (ROC) analysis to determine between-group differences and detection potential of the MBT. We found statistically large between-group differences with worse memory performance in paired cued recall conditions in AD-aMCI .050). The detection potential of MBT paired cued recall for differentiating memory impairment in AD-aMCI from CN yielded an AUC of 90% (95% CI, 85-96) and an AUC of 91% (95% CI, 81->99) between AD-aMCI and PD-MCI. Associative memory and binding impairment are most pronounced in AD-aMCI in comparison to PD-MCI and controls. Overall, the MBT is an efficient tool for the differential diagnosis of memory impairment due to the two most common neurodegenerative diseases.
期刊介绍:
The Journal of Neuropsychology publishes original contributions to scientific knowledge in neuropsychology including:
• clinical and research studies with neurological, psychiatric and psychological patient populations in all age groups
• behavioural or pharmacological treatment regimes
• cognitive experimentation and neuroimaging
• multidisciplinary approach embracing areas such as developmental psychology, neurology, psychiatry, physiology, endocrinology, pharmacology and imaging science
The following types of paper are invited:
• papers reporting original empirical investigations
• theoretical papers; provided that these are sufficiently related to empirical data
• review articles, which need not be exhaustive, but which should give an interpretation of the state of research in a given field and, where appropriate, identify its clinical implications
• brief reports and comments
• case reports
• fast-track papers (included in the issue following acceptation) reaction and rebuttals (short reactions to publications in JNP followed by an invited rebuttal of the original authors)
• special issues.
