The Assessment of Functional Abilities in the Diagnosis of MCI and Dementia in a Culturally Diverse Sample.

Abstract/Description
Previous studies suggested that the Functional Activities Questionnaire (FAQ-10) has minimal ethnic bias and that a shorter version (FAQ-6) can equally diagnose MCI and dementia. Objective: We analyzed whether FAQ-6 is similar to FAQ-10 in diagnosing MCI and dementia. We examined their applicability across European Americans (EA) and Hispanic Americans, and how scores correlated to beta amyloid. Method: 222 participants (116 EA) completed a neuropsychological battery, FAQ, and PET scans, and...

Objective: We analyzed whether FAQ-6 is similar to FAQ-10 in diagnosing MCI and dementia. We examined their applicability across European Americans (EA) and Hispanic Americans, and how scores correlated to beta amyloid. Method: 222 participants (116 EA) completed a neuropsychological battery, FAQ, and PET scans, and were classified as cognitively normal (CN), MCI, or dementia. The diagnostic capacity of FAQ-10 and FAQ-6 were compared for the total sample and across ethnic groups. Scores were correlated to beta amyloid. Results: Both versions showed good item discrimination. Ethnicity did not affect scores when controlling for diagnosis and education. Both versions classified CN and dementia, and positively correlated to beta amyloid. Conclusions: Results suggest FAQ-6 and FAQ-10 similarly predict diagnosis and is adequate in these ethnic groups.

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

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.
