Abstract/Description
Research shows intrusions in memory tests can predict cognitive impairment in abnormal aging. However, there still is a need for additional research regarding the association of intrusions in verbal fluency tasks and clinical diagnosis of mild cognitive impairment, and dementia. The aim of my master’s thesis research is to determine if there is an association between intrusion totals in verbal fluency tasks and diagnosis, longitudinally (across 3 years), if there are significant differences...
Show moreResearch shows intrusions in memory tests can predict cognitive impairment in abnormal aging. However, there still is a need for additional research regarding the association of intrusions in verbal fluency tasks and clinical diagnosis of mild cognitive impairment, and dementia. The aim of my master’s thesis research is to determine if there is an association between intrusion totals in verbal fluency tasks and diagnosis, longitudinally (across 3 years), if there are significant differences between category and phonemic fluency tasks in intrusion total scores, and if progression from CN to MCI or dementia and from MCI to dementia can be indicated through differences in intrusion scores. Results indicated that intrusions are significantly associated with diagnosis in Phonemic fluency tasks, however this was not the case in progressors versus non-progressors.

The Contribution of Depression to the Diagnosis of MCI and Dementia in a Culturally Diverse Sample of the United States

The Contribution of Depression to the Diagnosis of MCI and Dementia in a Culturally Diverse Sample of the United States.

Abstract/Description
Depression is associated with higher severity of memory disorders and has been shown to predict lower levels of cognitive functioning in those diagnosed with Mild Cognitive Impairment (MCI) or dementia. Yet, little is known about this association cross-culturally, particularly between Hispanics and European Americans. This study demonstrates that although levels of depression differed significantly across diagnostic group, Hispanics and European Americans were similar in levels of depression...
Show moreDepression is associated with higher severity of memory disorders and has been shown to predict lower levels of cognitive functioning in those diagnosed with Mild Cognitive Impairment (MCI) or dementia. Yet, little is known about this association cross-culturally, particularly between Hispanics and European Americans. This study demonstrates that although levels of depression differed significantly across diagnostic group, Hispanics and European Americans were similar in levels of depression at each diagnosis. However, only for the European American group did depression levels predict lower scores in confrontational naming and semantic memory. Additionally, exploratory analyses of the entire sample demonstrated that lower depression predicted less likelihood of MCI or dementia diagnoses. This could indicate that there is a need for intervention and treatment of depression, in particular for later stages of MCI and dementia, that should be culturally catered to individual ethnicities.

Recognizing Functional Decline in Persons with MCI (Mild Cognitive Impairment)
Title
Recognizing Functional Decline in Persons with MCI (Mild Cognitive Impairment).
Creator

Abstract/Description
Although not all persons with mild cognitive impairment (MCI) go on to develop Alzheimer's disease (AD), MCI is recognized as an early stage of AD. The effects of AD are devastating to all concerned. Research has identified that recognition of AD in its earliest stages and institution of known treatment modalities can forestall the ultimate outcome. Identification of the first subtle signs of MCI can assist in the recognition of this prodromal phase, and allow for institution of therapy while...
Show moreAlthough not all persons with mild cognitive impairment (MCI) go on to develop Alzheimer's disease (AD), MCI is recognized as an early stage of AD. The effects of AD are devastating to all concerned. Research has identified that recognition of AD in its earliest stages and institution of known treatment modalities can forestall the ultimate outcome. Identification of the first subtle signs of MCI can assist in the recognition of this prodromal phase, and allow for institution of therapy while still in the initial stages. Unfortunately, the development of MCI is insidious in nature, thus making it difficult to detect. The purpose of this study was to identify areas of functional decline that occur in MCI in an effort to improve its early identification. A mixed-methods design that combined qualitative and quantitative methods was used. Fifty-three participants with memory complaints were interviewed using a semi structured interview technique with open-ended questions, the Montreal Cognitive Assessment (MoCA), the Geriatric Depression Scale (GDS) and a list of eighty-five items previously identified as indicative of functional decline. Twenty-nine persons were divided into two groups: 1) those identified as probable MCI (consensus diagnosis) (n=15) and possible MCI (based on screening examination) (n=14) and 2) those identified as Normal (no cognitive impairment) (n=10), and their subjective functional deficits compared. The findings suggest that there were certain areas of functional decline more commonly experienced by persons in the MCI group than by unimpaired. These include difficulty recalling details of information and forgetting conversations. There were also other changes identified, such as adaptations on the part of persons with MCI (an increased dependence on memory aids, for example, lists and calendars) and a dec rease in social activities leading to an increase in social isolation. Additionally identified were functional activities that appear to remain intact in persons with early MCI. This study highlights the subtlety with which MCI assaults the functional abilities of individuals, thus making its early identification problematic. The results of this study will contribute by providing information that will help professionals who are assessing persons experiencing memory issues for the possible presence of MCI. Additionally, it is hoped that these findings will assist in the development of a measurement tool designed to assess for possible MCI.
