Prospective memory, the inability to remember an intended action, is a common complaint, but not formally assessed in most clinical and research studies of mild cognitive impairment (MCI). In this study, patients with amnestic mild cognitive impairment (aMCI), non-amnestic cognitive impairment (naMCI), and cognitively normal (CN) elders were assessed using the Miami Prospective Memory Test (MPMT). A unique aspect of the paradigm was that participants were scored for intention to perform, accuracy in recollection for specific elements of the task, and the need for reminder cues. Excellent test-retest stability was obtained for MPMT Event-Related (ER), combined Time-Related (TR) subscales, and total MPMT score for aMCI subjects. MPMT impairments were observed in 48.6% of aMCI, 29.4% of naMCI, and 10.0% of normal elderly participants. Prospective memory deficits were common in participants with aMCI, and occurred in almost a third of naMCI participants. Intention to perform and need for reminder cues were significantly more impaired than retrospective memory for specific details of the task. It is concluded that assessment of different elements of prospective memory is important in MCI research and that inability to remember intended actions is a significant feature in those as risk for Alzheimer's disease.
Objective The Rey Complex Figure Test (RCFT) has the potential to assess executive function deficits commonly associated with ADHD. While commonly scored using the visuospatial criterion established in the Qualitative Scoring System (QSS), alternative methods have incorporated administration using colored pencils to evaluate planning and organization. Existing literature has discouraged administration using the colored pencil approach given suggestion that distractibility will impair performance. The current study challenged the assumption that individuals with distractibility should not be exposed to color administration. Methods Data was extracted from files of ADHD individuals previously assessed at a southern Florida hospital. A total of 25 participants (11 females and 14 males) were included in the analysis. Methods of analysis included independent t-tests and ANOVA to explore moderating factors of age, sex, race and diagnostic presentation. Results This study found that performance across the various parts of the test were not significantly different based on administration method (t = −1.021, p = 0.318, 95% CI: −4.3755, 1.4845). Interestingly, an ANOVA revealed no significant differences between the broad demographic groups in their performance. Independent t-test did not indicate that the RCFT performance could differentiate between types of ADHD (t = 0.118, p = 0.907, 95% CI: −2.8420, 3.1862). Conclusion In contrast to the RCFT manual, the results of the data analysis revealed no significant differences between administration methods in a highly inattentive population group. This study provides the basis for the introduction of studying the RCFT as a diagnostic tool for re-assessing ADHD throughout adulthood.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
