Item Response Analysis of the Financial Capacity Instrument-Short Form.

OBJECTIVE: The Financial Capacity Instrument-Short Form (FCI-SF) is a performance-based measure of everyday financial skills that takes 15 min to administer. Although the FCI-SF has demonstrated excellent psychometric properties, advanced psychometric methods such as item response theory (IRT) can provide important information on the performance of individual test items in measuring financial capacity and in distinguishing between healthy and cognitively impaired individuals. METHOD: Participants were 272 older adults diagnosed with mild cognitive impairment (MCI) and 1,344 cognitively healthy controls recruited from the Mayo Clinic Study of Aging at the Mayo Clinic in Rochester, Minnesota and also from the Cognitive Observations in Seniors study at the University of Alabama at Birmingham. Participants in each study were administered the FCI-SF, which evaluates coin/currency calculation, financial conceptual knowledge, use of a checkbook/register, and use of a bank statement. RESULTS: A unidimensional two-parameter logistic model best fit the 37 FCI-SF Test items, and most FCI-SF items fit the unidimensional two-parameter model well. The results indicated that all FCI-SF items robustly distinguished cognitively healthy controls from persons with MCI. CONCLUSIONS: The study results showed that the FCI-SF performed well under IRT analysis, further highlighted the psychometric properties of the FCI-SF as a valid and reliable measure of financial capacity, and demonstrated the clinical utility of the FCI-SF in distinguishing between cognitively normal and cognitively impaired individuals.

Development and implementation of an electronic Clinical Dementia Rating and Financial Capacity Instrument-Short Form.

Introduction: To address the need for remote assessments of cognitive decline and dementia, we developed and administered electronic versions of the Clinical Dementia Rating (CDR®) and the Financial Capacity Instrument-Short Form (FCI-SF) (F-CAP®), called the eCDR and eFCI, respectively. Methods: The CDR and FCI-SF were adapted for remote, unsupervised, online use based on item response analysis of the standard instruments. Participants completed the eCDR and eFCI first in clinic, and then at home within 2 weeks. Results: Of the 243 enrolled participants, 179 (73%) cognitively unimpaired (CU), 50 (21%) with mild cognitive impairment (MCI) or dementia, and 14 (6%) with an unknown diagnosis, 84% and 85% of them successfully completed the eCDR and eFCI, respectively, at home. Discussion: These results show initial feasibility in developing and administering online instruments to remotely assess and monitor cognitive decline along the CU to MCI/very mild dementia continuum. Validation is an important next step.

Association of Performance on the Financial Capacity Instrument-Short Form With Brain Amyloid Load and Cortical Thickness in Older Adults.

Background and Objectives: To investigate the association of the Financial Capacity Instrument-Short Form (FCI-SF) performance and timing total scores with brain ß-amyloid and cortical thickness in cognitively unimpaired (CU) (at baseline) older adults. Methods: A total of 309 participants (aged 70 years or older) of the Mayo Clinic Study of Aging underwent 11C-Pittsburgh compound B PET amyloid imaging and MRI, and completed the FCI-SF. Abnormal amyloid PET was defined as standardized uptake value ratio ≥1.48 in an Alzheimer disease (AD)-related region of interest and reduced AD signature cortical thickness as ≤2.68 mm (neurodegeneration). A cohort of 218 (of the 309) participants had follow-up visits (every 15 months) with FCI-SF data for longitudinal analysis (number of visits including baseline, median [range]: 2 [2-4]). In the analysis, we used linear regression and mixed-effects models adjusted for age, sex, education, apolipoprotein E ε4 allele status, global cognitive z score, and previous FCI-SF testing. Results: Participants' mean age (SD) was 80.2 (4.8) years (56.3% male individuals). In cross-sectional analysis, abnormal amyloid PET (vs normal) was associated with a lower FCI-SF total score and slower total composite time. In longitudinal analysis, FCI-SF total score declined faster (difference in annualized rate of change, beta coefficient [ß] [95% confidence interval (CI)] = -1.123 [-2.086 to -0.161]) and FCI-SF total composite time increased faster (difference in annualized rate of change, ß [95% CI] = 16.274 [5.951 to 26.597]) for participants with neurodegeneration at baseline (vs those without). Participants who exhibited both abnormal amyloid PET and neurodegeneration at baseline had a greater increase in total composite time when compared with the group without abnormal amyloid and without neurodegeneration (difference in annualized rate of change, ß [95% CI] = 16.750 [3.193 to 30.307]). Discussion: Performance and processing speed on the FCI-SF were associated with imaging biomarkers of AD pathophysiology in CU (at baseline) older adults. Higher burdens of imaging biomarkers were associated with longitudinal worsening on FCI-SF performance. Additional research is needed to delineate further these associations and their predictive utility at the individual person level.

Assessment of Testamentary Capacity in Older Adults: Description and Initial Validation of a Standardized Interview Instrument.

OBJECTIVE: Testamentary capacity (TC) is a legal construct, which concerns a person's mental capacity to make or amend a will. Although expert clinicians are frequently asked to assess TC in forensic settings, there are few instruments and little empirical research to inform and guide their assessments. The present study describes the development and psychometric properties of a standardized assessment measure of TC (Testamentary Capacity Instrument-TCI), and investigates its reliability and validity. METHODS: The TCI is an interview-based, psychometric measure, which assesses a testator's knowledge of four conceptual elements, which together comprise the legal basis for TC in the Anglo-American legal system: (1) what a will is, (2) nature and extent of assets/property, (3) possible heirs/claimants to property, and (4) plan to distribute assets to heirs after death. Cronbach's alpha and percentage exact agreement were used to examine TCI element reliabilities. Using independent samples t-tests, MANOVA and MANCOVA, we investigated validity by comparing TCI element performance of cognitively intact older adults (n = 22) and older adults with ad dementia (n = 20). RESULTS: The TCI elements showed good internal consistency and good inter-rater reliability. The ad group performed significantly below the control group on all four TCI elements, with effect sizes exceeding 1.2, suggesting that the TCI has content and construct validity. CONCLUSIONS: Relative to cognitively intact older adults, older adults with ad dementia showed significant impairment on all four TCI conceptual elements. The TCI has promise as a standardized quantitative measure of TC to support clinical assessment of TC in forensic settings.

Cognitive Processing Speed Is Strongly Related to Driving Skills, Financial Abilities, and Other Instrumental Activities of Daily Living in Persons With Mild Cognitive Impairment and Mild Dementia.

BACKGROUND: Cognitive processing speed is important for performing everyday activities in persons with mild cognitive impairment (MCI). However, its role in daily function has not been examined while simultaneously accounting for contributions of Alzheimer's disease (AD) risk biomarkers. We examine the relationships of processing speed and genetic and neuroimaging biomarkers to composites of daily function, mobility, and driving. METHOD: We used baseline data from 103 participants on the MCI/mild dementia spectrum from the Applying Programs to Preserve Skills trial. Linear regression models examined relationships of processing speed, structural magnetic resonance imaging (MRI), and genetic risk alleles for AD to composites of performance-based instrumental activities of daily living (IADLs), community mobility, and on-road driving evaluations. RESULTS: In multivariable models, processing speed and the brain MRI neurodegeneration biomarker Spatial Pattern of Abnormality for Recognition of Early Alzheimer's disease (SPARE-AD) were significantly associated with functional and mobility composite performance. Better processing speed and younger age were associated with on-road driving ratings. Genetic risk markers, left hippocampal atrophy, and white matter lesion volumes were not significant correlates of these abilities. Processing speed had a strong positive association with IADL function (p < .001), mobility (p < .001), and driving (p = .002). CONCLUSIONS: Cognitive processing speed is strongly and consistently associated with critical daily functions in persons with MCI in models including genetic and neuroimaging biomarkers of AD risk. SPARE-AD scores also significantly correlate with IADL performance and mobility. Results highlight the central role of processing speed in everyday task performance among persons with MCI/mild dementia.

Anosognosia of financial ability in mild cognitive impairment.

OBJECTIVES: Although financial ability has been well-studied in mild cognitive impairment (MCI) and Alzheimer's disease (AD) using performance-based financial capacity assessment instruments, research is limited investigating everyday financial problems and declines in persons with AD and MCI and the insight of people with MCI to recognize that financial capacity declines are occurring. To address this gap in the research, we investigated everyday financial activities and skills in a sample of older adults representing the dementia spectrum. METHODS: Participants were 186 older adults in three diagnostic classifications: cognitively healthy, MCI likely due to AD, and mild AD dementia. Everyday financial ability was assessed using the Current Financial Activities Report (CFAR). The CFAR is a standardized report-based measure which elicits participant and study partner ratings about a participant's everyday financial abilities. RESULTS: Results showed that both CFAR self- and study partner-report distinguished diagnostic groups on key financial capacity variables in a pattern consistent with level of clinical pathology. Study partner-report indicated higher levels of financial skill difficulties in study participants than did the self-report of the same study participants. Study partner-ratings were more highly correlated with participant scores on a performance-based measure of financial capacity than were participant self-ratings. Results also showed that loss of awareness of financial decline is emerging at the MCI stage of AD. CONCLUSIONS: People with MCI represent a group of older adults at particular risk for financial missteps and-similar to people with AD-are in need of supervision of their financial skills and activities.

Declining Financial Capacity in Mild Cognitive Impairment: A Six-Year Longitudinal Study.

OBJECTIVE: To investigate financial skill decline over a 6-year period in persons with mild cognitive impairment (MCI) presumed due to Alzheimer's disease (AD). METHODS: Study participants were cognitively normal (CN) older adults (n = 82) and adults with MCI (n = 91) based on consensus conference diagnosis. Participants completed baseline and up to six annual follow-up assessments that included standardized financial skills measurement (Financial Capacity Instrument; FCI; nine FCI domain and two global scores). We examined FCI change over time using mixed-model repeated measures analysis adjusted for baseline age and follow-up duration. RESULTS: At baseline, the CN group performed better than the MCI group across both global and seven domain scores. Group × Time interaction effects (all p's <.02) were found for all global and domain scores. The largest interaction effects were observed for complex domains of Financial Conceptual Knowledge, Checkbook Management, Bank Statement Management, and Bill Payment (all p's <.0001). Annualized decline in the MCI group's global scores, calculated in relation to CN group performance, was 10-17% over the initial 3-year time span and 22-24% at 6 years. Decline in FCI domain scores ranged from 6% (Knowledge of Assets/Estate) to 22% (Investment Decision-Making) at 3 year follow-up, and from 15% (Basic Monetary Skills) to 37% (Financial Judgment) at 6 year follow-up. CONCLUSIONS: Over a 6-year period, persons with MCI demonstrated significant declines in multiple financial skills and in particular financial judgment. The findings highlight the importance of ongoing oversight by family members and clinicians of financial skills and activities in persons with MCI.

Exploring the Factor Structure of Financial Capacity in Cognitively Normal and Impaired Older Adults.

OBJECTIVES: To investigate the factor structure of financial capacity using a direct-performance measure of financial skills (The Financial Capacity Instrument [FCI]) as a proxy for the financial capacity construct. METHODS: The study sample was composed of 440 older adults who represented the cognitive spectrum from normal cognitive aging to mild cognitive impairment (MCI) to mild dementia: 179 healthy older adults, 149 participants with MCI, and 112 participants with mild Alzheimer's dementia (AD). RESULTS: Both Velicer's Minimum Average Partial test and Horn's parallel analysis supported a four-factor solution which accounted for 46% of variance. The four extracted factors were interpreted as: (1) Basic Monetary Knowledge and Calculation Skills, (2) Financial Judgment, (3) Financial Conceptual Knowledge, and (4) Financial Procedural Knowledge. CONCLUSIONS: The study findings represent an important first step in empirically articulating the financial capacity construct in aging. The four identified factors can guide both clinical practice and future instrument utilization and development. CLINICAL IMPLICATIONS: Cognitively impaired older adults with MCI and mild AD dementia are likely to show financial changes in one or more of the four identified financial factors. Clinicians working with older adults should routinely examine for potential changes in these four areas of financial function.

White Matter Degradation is Associated with Reduced Financial Capacity in Mild Cognitive Impairment and Alzheimer's Disease.

Financial capacity (FC) is a cognitively complex activity of daily living that declines in mild cognitive impairment (MCI) and Alzheimer's disease (AD), limiting an individual's ability to manage one's finances and function independently. The neural underpinnings of this decline in function are poorly understood but likely involve age-related and disease-related degradation across structural networks. The purpose of the current study was to determine if altered white matter integrity is associated with declining FC in persons with MCI and AD compared to older controls. Individuals with MCI due to AD (n = 31), mild dementia (n = 39), and cognitively healthy older adults (n = 60) were administered a neuropsychological battery including the FC Instrument, a performance-based measure of FC. All 130 participants also underwent diffusion tensor imaging (DTI) upon which tract-based spatial statistics were performed. Both FC and white matter integrity decreased in accordance with disease severity with little to no effect in healthy elderly, significant effects in MCI, and greater effects in AD. Regional white matter degradation (increased diffusivities and decreased fractional anisotropy) was associated with reduced FC in both MCI and AD groups even after controlling for age, education, and gender. Specifically, in MCI, decreased fractional anisotropy, but not increased diffusivities, was associated with poorer FC in widespread cingulo-parietal-frontal and temporo-occipital areas. In AD, rather than anisotropy, increased mean and axial diffusivities in anterior cingulate, callosum, and frontal areas associated with poorer FC. These findings suggest a severity gradient of white matter degradation across DTI metrics and AD stages that predict declining financial skill and knowledge.

Financial Capacity and its Cognitive Predictors in Progressive Multiple Sclerosis.

OBJECTIVE: Financial capacity is a cognitively-complex activity of daily living that has been shown to decline in a number of neurocognitive disorders. Although it has been well established that cognitive decline is common in multiple sclerosis (MS), little is known about possible financial capacity impairment in people with MS. Thus, the objective of the current study is to investigate financial capacity and its neurocognitive correlates in MS. METHODS: Data from 22 people with progressive MS and a healthy comparison group composed of 18 adults were analyzed. MS diagnoses were made by a board-certified neurologist with experience in MS. Study participants were administered the Financial Capacity Instrument, a performance-based measure of financial capacity, and neuropsychological battery. RESULTS: Overall financial capacity and most complex financial domains were significantly poorer for people with progressive MS in relation to the healthy comparison group, and a number of cognitive variables were associated with financial capacity declines. CONCLUSIONS: Financial capacity is a complex cognitively-mediated functional ability that was impaired in 50% of the current sample of people with progressive MS. These results indicate that people with progressive MS are at greater risk for showing impairment in complex financial tasks and should be clinically monitored for possible deficits in financial capacity.

Neurocognitive Predictors of Declining Financial Capacity in Persons with Mild Cognitive Impairment.

OBJECTIVE: To identify cognitive predictors of declining financial capacity (FC) in persons with mild cognitive impairment (MCI). METHODS: Participants were 66 cognitively normal older adults and 49 persons with MCI who completed neuropsychological testing and a performance measure of financial capacity (Financial Capacity Instrument; FCI) at baseline and two-year follow-up. We calculated two-year change scores for neuropsychological tests and FCI total score. We examined bivariate correlations between demographic/clinical variables and FCI change score, and between neuropsychological and FCI change scores. The five strongest bivariate correlates were entered into a linear regression analysis to identify longitudinal predictors of financial decline within group. RESULTS: Persons with MCI showed significant decline on the FCI and most cognitive variables, while controls demonstrated relatively stable performance. For persons with MCI, education correlated with FCI change score. The top four cognitive variable-FCI change score correlations were written arithmetic, confrontation naming, immediate visual memory, and visual attention. In the regression model, written arithmetic was the primary predictor and visual memory and visual attention were secondary predictors of two-year FCI change scores. CONCLUSION: Semantic arithmetic knowledge, and to a lesser extent visual memory and attention, are key longitudinal cognitive predictors of financial skill decline in individuals with MCI. CLINICAL IMPLICATIONS: Clinicians should consider neurocognitive abilities of written arithmetic, visual memory, and processing speed in their assessments of financial capacity in person with MCI.

Capacity for financial decision making in multiple sclerosis.

INTRODUCTION: Cognitive impairment often occurs in people with multiple sclerosis (MS), and dysfunction involving executive function, new learning, and working memory is especially common. Compromised activities of daily living are linked to this cognitive impairment, and people with MS are apt to be unemployed and struggle to manage domestic responsibilities. Financial decision making is an important activity of daily living, and no study has examined whether it is compromised by neuropsychological dysfunction in people with MS. METHOD: A battery of neuropsychological tests and a measure of financial decision making (Financial Capacity Instrument, FCI: Marson, D. C. 2001. Loss of financial capacity in dementia: Conceptual and empirical approaches. Aging, Neuropsychology, and Cognition, 8, 164-181) were administered to 50 participants (34 patients with MS and 16 cognitively healthy adults). Based on the neuropsychological test results, 14 patients were classified as having cognitive impairment, and 20 had no significant impairment. RESULTS: The impaired MS patients performed significantly worse than unimpaired patients and the healthy comparison group on most financial tasks. The impaired group retained abilities to count money and display adequate financial judgment. Regression analyses showed that measures of mental flexibility and working memory correlated most strongly with performance on the FCI domains across groups. CONCLUSIONS: Cognitively impaired patients with MS have degraded financial skills, which are linked to executive function and working memory deficits.

Cognitive, social, and neural determinants of diminished decision-making and financial exploitation risk in aging and dementia: A review and new model.

In this article we will briefly review how changes in brain and in cognitive and social functioning, across the spectrum from normal to pathological aging, can lead to decision-making impairments that increase abuse risk in many life domains (e.g., health care, social engagement, financial management). The review will specifically focus on emerging research identifying neural, cognitive, and social markers of declining financial decision-making capacity in older adults. We will highlight how these findings are opening avenues for early detection and new interventions to reduce exploitation risk.

Conceptual Models and Guidelines for Clinical Assessment of Financial Capacity.

The ability to manage financial affairs is a life skill of critical importance, and neuropsychologists are increasingly asked to assess financial capacity across a variety of settings. Sound clinical assessment of financial capacity requires knowledge and appreciation of applicable clinical conceptual models and principles. However, the literature has presented relatively little conceptual guidance for clinicians concerning financial capacity and its assessment. This article seeks to address this gap. The article presents six clinical models of financial capacity : (1) the early gerontological IADL model of Lawton, (2) the clinical skills model and (3) related cognitive psychological model developed by Marson and colleagues, (4) a financial decision-making model adapting earlier decisional capacity work of Appelbaum and Grisso, (5) a person-centered model of financial decision-making developed by Lichtenberg and colleagues, and (6) a recent model of financial capacity in the real world developed through the Institute of Medicine. Accompanying presentation of the models is discussion of conceptual and practical perspectives they represent for clinician assessment. Based on the models, the article concludes by presenting a series of conceptually oriented guidelines for clinical assessment of financial capacity. In summary, sound assessment of financial capacity requires knowledge and appreciation of clinical conceptual models and principles. Awareness of such models, principles and guidelines will strengthen and advance clinical assessment of financial capacity.

Both Financial and Cognitive Decline Predict Clinical Progression in MCI.

We investigated the roles of financial/functional and cognitive abilities in predicting clinical progression in patients with mild cognitive impairment (MCI). In a longitudinal sample of 51 patients with consensus conference diagnosed MCI likely due to Alzheimer disease (AD), two-year change scores were calculated for a performance measure of functional ability, cognitive variables, and 3 outcome measures used to track progression in neurological disorders. We examined patterns of financial and cognitive decline across the 2-year study period, and used these data and the 3 outcome variables to construct discrete predictor models of clinical progression in MCI. We found that both financial skills and cognitive abilities declined over the 2-year study period, were significantly associated with clinical progression, and contributed unique variance to all 3 predictor models. The resulting models accounted for 40% to 75% of variance in clinical progression across outcome variables. Taken together, our results indicate that changes in both cognitive abilities and higher order functional skills appear integral to understanding clinical progression in MCI likely due to AD. Specifically, declines in financial skills contribute unique variance to measures commonly used to track progression in neurological disorders associated with aging, and thus represent an important functional marker of clinical progression in prodromal AD.

Age and education corrected older adult normative data for a short form version of the Financial Capacity Instrument.

Financial capacity is an instrumental activity of daily living (IADL) that comprises multiple abilities and is critical to independence and autonomy in older adults. Because of its cognitive complexity, financial capacity is often the first IADL to show decline in prodromal and clinical Alzheimer's disease and related disorders. Despite its importance, few standardized assessment measures of financial capacity exist and there is little, if any, normative data available to evaluate financial skills in the elderly. The Financial Capacity Instrument-Short Form (FCI-SF) is a brief measure of financial skills designed to evaluate financial skills in older adults with cognitive impairment. In the current study, we present age- and education-adjusted normative data for FCI-SF variables in a sample of 1344 cognitively normal, community-dwelling older adults participating in the Mayo Clinic Study of Aging (MCSA) in Olmsted County, Minnesota. Individual FCI-SF raw scores were first converted to age-corrected scaled scores based on position within a cumulative frequency distribution and then grouped within 4 empirically supported and overlapping age ranges. These age-corrected scaled scores were then converted to age- and education-corrected scaled scores using the same methodology. This study has the potential to substantially enhance financial capacity evaluations of older adults through the introduction of age- and education-corrected normative data for the FCI-SF by allowing clinicians to: (a) compare an individual's performance to that of a sample of similar age and education peers, (b) interpret various aspects of financial capacity relative to a normative sample, and (c) make comparisons between these aspects.

Clinical and ethical aspects of financial capacity in dementia: a commentary.

In contrast to issues like treatment and research consent capacity, financial capacity has received relatively little clinical and ethical attention in the dementia literature. Yet issues of financial capacity emerge frequently in patients with Alzheimer's disease (AD), Parkinson's disease (PD) and related dementias, and commonly present ethical and clinical challenges for clinicians treating these patients. These issues include whether a patient with possible dementia has sufficient capacity independently to manage their financial affairs, needs referral for financial capacity assessment, and/or is being financially exploited or abused by others. The accurate identification, assessment and successful handling of such financial capacity issues can have a substantial impact on the financial and psychological well-being of patients and their family members. The present commentary presents an overview of financial capacity and associated clinical and ethical issues in dementia, and describes a set of possible clinician roles regarding these issues as they arise in clinical practice. The commentary concludes with a section describing educational resources available to clinicians and bioethicists seeking additional guidance in handling financial capacity issues. The ultimate goal of the paper is to focus clinical and ethical attention on a neglected capacity that is of fundamental importance for patients, families, and health care and legal professionals.

Impaired financial abilities in Parkinson's disease patients with mild cognitive impairment and dementia.

PURPOSE: Financial capacity (FC) is an instrumental activity of daily living (IADL) critical to independent functioning and sensitive to cognitive impairment in dementia. Little is known about FC in cognitively impaired patients with Parkinson's disease (PD). The present study investigated FC in PD patients with prodromal and clinical dementia. METHODS: Participants were 20 older controls and 35 PD patients who met consensus criteria for either mild cognitive impairment (PD-MCI, n = 18) or PD dementia (PDD, n = 17). FC was assessed using a standardized performance based measure consisting of 9 domain and two global scores (Financial Capacity Instrument; FCI) (1). FCI domain and global performance scores were compared across groups. Capacity impairment ratings (no impairment, mild/moderate impairment, severe impairment) were calculated for each PD patient's domain and global scores. RESULTS: Relative to controls, PD-MCI patients were impaired on both FCI global scores and domains of basic monetary skills, financial concepts, and investment decision-making. Relative to both controls and PD-MCI patients, PDD patients were impaired on virtually all FCI variables. With respect to impairment ratings, greater than 50% of PD-MCI patients and greater than 90% of PDD patients were classified as either mild/moderate or severely impaired on the two FCI global scores. CONCLUSIONS: Impairment of financial capacity is already present in PD-MCI and is advanced in PDD. Complex cognitively-mediated IADLs such as financial capacity appear to be impaired early in the course of PD dementia.

Assessment of capacity in an aging society.

Over the past 40 years, the assessment and scientific study of capacity in older adults has emerged as a distinct field of clinical and research activity for psychologists. This new field reflects the convergence of several trends: the aging of American society, the growing incidence and prevalence of dementia, and the patient rights, deinstitutionalization, and disability rights movements. Because of these forces, capacity issues now permeate the fabric of everyday life, whether in the form of guardianship petitions, questions of capacity to consent to treatment, the ability to make a new will, or participation in human research. In seeking to resolve these issues, families, clinicians, and legal professionals increasingly turn to psychologists to assess a capacity and to provide empirically supported judgments that properly balance autonomy and protection for the individual. Psychologists have taken a leading role in the development of functional assessment instruments that measure important aspects of the capacity construct. In addition, psychology has been a major contributor to the scientific study of capacity. In collaboration with colleagues from medicine and law, psychologists have articulated crucial theoretical frameworks that integrate legal, clinical, and ethical dimensions of the capacity problem. This article focuses on the evolution of theory, law, science, and practice in the evaluation of capacity in older adults and its recent culmination in a series of interdisciplinary handbooks sponsored by the American Psychological Association and the American Bar Association.

MRI volume of the medial frontal cortex predicts financial capacity in patients with mild Alzheimer's disease.

Persons with mild Alzheimer's disease (AD) have significant deficits in financial abilities. This study examined the relationship between brain structure volumes, cognition, and financial capacity in patients with mild AD. Sixteen mild AD patients and 16 older adult comparisons completed the Financial Capacity Instrument (FCI), a psychometric measure of financial abilities, and also underwent magnetic resonance imaging (MRI) to obtain volumes of the bilateral hippocampi, angular gyri, precunei, and medial and dorsolateral frontal cortices. Mild AD patients performed significantly below comparisons on the FCI and had significantly smaller hippocampi. Among mild AD patients, FCI performance was moderately correlated with frontal (medial and dorsolateral frontal cortex) and posterior (angular gyri and precunei) cortical volumes. Stepwise regression demonstrated that medial frontal cortex volume predicted FCI score. The relationship between medial frontal cortex volume and overall FCI score was partially mediated by two measures of simple attention (DRS Attention, DRS Construction). The findings suggest that medial frontal cortex atrophy and associated declines in simple attention play an increasingly important role in declining financial skills in patients with mild AD.
