Medication self-management in predominantly African American and Caribbean American people with epilepsy: The role of medication beliefs and epilepsy knowledge.

INTRODUCTION: Suboptimal medication adherence is common in people with epilepsy (PWE) and disproportionally prevalent among racially/ethnically diverse patients. Understanding reasons and risks of suboptimal adherence is critical to developing interventions that reduce negative health outcomes. This cross-sectional study characterized common barriers to medication self-management, prevalence of negative medication beliefs, and gaps in epilepsy knowledge among predominantly African American and Caribbean American PWE and examined their interrelationships. MATERIALS AND METHODS: Sixty-three PWE (Age = 42.1 ± 13.2; 60% female; 79% Black; 19% Hispanic/Latino) completed validated self-report questionnaires about medication self-management, medication beliefs, and epilepsy knowledge. Correlations and t-tests examined interrelationships. RESULTS: Four barriers to medication self-management were common, including not taking antiseizure medications at the same time every day, forgetting doses, not planning refills before running out, and spreading out doses when running low. More than half the sample believed medications were overused by prescribers. Nearly one-third believed medications were harmful, and nearly a quarter believed their antiseizure medications were minimally necessary with almost half reporting elevated concerns about negative consequences of antiseizure medications. Poorer medication self-management was associated with stronger beliefs that medications in general are harmful/overused by prescribers. Individuals who were "accepting" of their antiseizure medications (i.e., high perceived necessity, low concerns) were less likely to spread out time between doses when running low compared to non-accepting counterparts. Knowledge gaps related to the cause of seizures/epilepsy, chronicity of epilepsy treatment, and seizure semiology/diagnosis were common. Nevertheless, epilepsy knowledge was unrelated to medication self-management and medication beliefs. CONCLUSIONS: In these PWE, the most prevalent reasons for suboptimal medication self-management were behaviorally mediated and potentially modifiable. Negative medication beliefs and misconceptions about epilepsy and its treatment were common. Results further suggest that interventions addressing negative medication beliefs will be more effective than knowledge-based psychoeducation alone to improve medication self-management in this patient population.

Verbal memory is associated with adherence to COVID-19 protective behaviors in community dwelling older adults.

BACKGROUND: Adherence to protective behaviors is central to limiting the spread of COVID-19 and associated risk of serious illness and mortality in older populations. Whether cognition predicts adherence to protective behaviors has not been examined in older adults. AIMS: To examine whether specific cognitive abilities predict adherence to COVID-19 protective behaviors in older adults, independent of other relevant factors. METHODS: Data from 431 older adults (i.e., ≥ 65 years) who took part in the COVID-19 module of the Health and Retirement Study were included in the present study. Separate binary logistic regression models were used to examine whether performance on measures of immediate and delayed recall and working memory predicted adherence to COVID-19 protective behaviors, controlling for demographics, level of COVID-19 concern, depressive symptoms, and medical conditions. RESULTS: For every unit increase in immediate and delayed recall, the probability of adhering to COVID-19 protective behaviors increased by 47% and 69%, respectively. There was no association between the measure of working memory and adherence. DISCUSSION: It is of public interest to understand the factors that reduce adherence to protective behaviors so that we can better protect those most vulnerable and limit community spread. Our findings demonstrate that reduced memory predicts non-adherence to COVID-19 protective behaviors, independent of virus concern, and other relevant demographic and health factors. CONCLUSIONS: Public health strategies aimed at increasing adherence to COVID-19 protective behaviors in community dwelling older adults, should account for the role of reduced cognitive function in limiting adherence.

Discrepancy-Based Evidence for Loss of Thinking Abilities (DELTA): Development and Validation of a Novel Approach to Identifying Cognitive Changes.

OBJECTIVE: To develop and validate the Discrepancy-based Evidence for Loss of Thinking Abilities (DELTA) score. The DELTA score characterizes the strength of evidence for cognitive decline on a continuous spectrum using well-established psychometric principles for improving detection of cognitive changes. METHODS: DELTA score development used neuropsychological test scores from the Alzheimer's Disease Neuroimaging Initiative (ADNI) cohort (two tests each from Memory, Executive Function, and Language domains). We derived regression-based normative reference scores using age, gender, years of education, and word-reading ability from robust cognitively normal ADNI participants. Discrepancies between predicted and observed scores were used for calculating the DELTA score (range 0-15). We validated DELTA scores primarily against longitudinal Clinical Dementia Rating-Sum of Boxes (CDR-SOB) and Functional Activities Questionnaire (FAQ) scores (baseline assessment through Year 3) using linear mixed models and secondarily against cross-sectional Alzheimer's biomarkers. RESULTS: There were 1359 ADNI participants with calculable baseline DELTA scores (age 73.7 ± 7.1 years, 55.4% female, 100% white/Caucasian). Higher baseline DELTA scores (stronger evidence of cognitive decline) predicted higher baseline CDR-SOB (ΔR2 = .318) and faster rates of CDR-SOB increase over time (ΔR2 = .209). Longitudinal changes in DELTA scores tracked closely and in the same direction as CDR-SOB scores (fixed and random effects of mean + mean-centered DELTA, ΔR2 > .7). Results were similar for FAQ scores. High DELTA scores predicted higher PET-Aß SUVr (ρ = 324), higher CSF-pTau/CSF-Aß ratio (ρ = .460), and demonstrated PPV > .9 for positive Alzheimer's disease biomarker classification. CONCLUSIONS: Data support initial development and validation of the DELTA score through its associations with longitudinal functional changes and Alzheimer's biomarkers. We provide several considerations for future research and include an automated scoring program for clinical use.

Depressive Symptoms Contribute to Executive Deficits in Temporal Lobe Epilepsy.

This study examined the contribution of depression to reduced executive functioning in temporal lobe epilepsy (TLE) using three groups: TLE only (TLE; N=29), TLE+depression (TLE+DEP) (N=22), and nonneurologic participants with depression (DEP; N=31). Participants completed the Delis-Kaplan Executive Function System. Individuals with TLE performed worse than the DEP group on many tests of executive functions. Among the TLE participants, those with depression demonstrated poorer executive functioning. These findings support the notion that depression may further contribute to executive difficulties in individuals with TLE. Depression treatment in this population could lead to improvements in cognition.

Video Feedback Intervention to Enhance the Safety of Older Drivers With Cognitive Impairment.

OBJECTIVE: To demonstrate that g-force technology can be used to help older adults with cognitive impairment improve their driving safety as part of an in-car video feedback intervention. METHOD: Unsafe driving events triggered g-forces leading to capture of video clips. The program included 3 mo of monitoring without intervention, 3 mo of intervention (weekly written progress reports, a DVD of unsafe driving events, and weekly telephone contacts), and 3 mo of postintervention monitoring. RESULTS: Mean total unsafe driving events per 1,000 miles were reduced from baseline by 38% for 9 of 12 participants during the intervention and by 55% for 7 participants during postintervention monitoring. Mean total unsafe driving severity scores per 1,000 miles were reduced from baseline by 43% during the intervention and by 56% during postintervention monitoring. CONCLUSION: Preliminary results suggest that driving safety among older drivers with cognitive impairment can be improved using a behavior modification approach aimed at problem behaviors detected in their natural driving environment.

Psychosocial telephone intervention for dementia caregivers: A randomized, controlled trial.

BACKGROUND: Identifying effective and accessible interventions for dementia caregivers is critical as dementia prevalence increases. OBJECTIVE: Examine the effects of a telephone-based intervention on caregiver well-being. DESIGN: Randomized, controlled trial. SETTING: Academic medical center. PARTICIPANTS: Two hundred and fifty distressed, family, dementia caregivers. INTERVENTION: Caregivers randomized to receive 16 telephone contacts over 6 months of either the Family Intervention: Telephone Tracking-Caregiver (FITT-C) or Telephone Support (TS). OUTCOME: Primary outcome variables were family caregivers' depressive symptoms, burden, and reactions to care recipients' behavior problems at 6 months. RESULTS: The FITT-C intervention resulted in significantly improved caregiver depressive symptoms (P = .003; 27% net improvement) and less severe reactions to care-recipient depressive behaviors (P = .009; 29% net improvement) compared with the control condition (TS). CONCLUSION: An entirely telephone-based intervention improves caregivers' depressive symptoms and reactions to behavior problems in the care recipient and is comparable with reported results of face-to-face interventions.

Comparing caregiver and clinician predictions of fitness to drive in people with Alzheimer's disease.

This observational study investigated family caregiver and clinician ratings of 75 drivers with Alzheimer's disease against scores on a standardized road test and a naturalistic driving evaluation. Clinician ratings by a physician specialized in dementia were significantly associated with road test error scores (r=.25, p=.03) but not naturalistic driving errors or global ratings of road test and naturalistic driving performance. Caregiver ratings were unrelated to either driving assessment, with two exceptions; adult child ratings of driving ability were correlated with road test error scores (r=.43, p=.02), and spousal ratings were inversely correlated with global ratings. Clinician ratings of driving competence were modestly correlated with road test performance, but caregiver ratings were more complex. Adult children may be more accurate reporters of driving ability than spouses, possibly because of less personal bias, but the reasons behind this discrepancy need further investigation.

Understanding Health Beliefs and Health Behaviors in Older Adults at Risk for Alzheimer's Disease.

Background: There are significant public health benefits to delaying the onset of Alzheimer's disease (AD) in individuals at risk. However, adherence to brain healthy behaviors is low. The Health Belief Model proposes that specific beliefs are mediators of behavior change. Objective: To characterize health belief measures from the Science of Behavior Change Research Network (SBCRN) in an older adult population and associations between health beliefs, AD risk, and current health behaviors. Methods: A total of 172 individuals from the Rhode Island AD Prevention Registry participated. SBCRN health belief measures included assessments of future time perspective, self-efficacy, deferment of gratification, and consideration of future consequences. Outcome measures included individual AD risk index score, dementia risk awareness, and lifestyle behaviors including physical, cognitive, and social activity. Results: Participants who were older had higher scores for AD risk, lower future time perspective, and lower generalized self-efficacy (all at p < 0.001). Higher generalized self-efficacy was related to increased physical activity (p < 0.010). Higher future time perspective (p < 0.001) and generalized self-efficacy (p = 0.48) were associated with lower AD risk score. Subjective cognitive decline (SCD) was associated with lower self-efficacy, ability to delay gratification, and a less expansive future time perspective. Conclusions: Greater self-efficacy and perceived future time remaining were associated with lower AD risk and greater engagement in physical activity. SCD was associated with health beliefs that may negatively affect engagement in positive brain health behaviors. Assessment of and psychoeducation about these intrapersonal health belief constructs may be important targets for behavioral interventions to reduce AD risk.

Medication management error types: Associations with mild cognitive impairment subtype.

Objective: Medication management errors are suspected to be prevalent among older adults with mild cognitive impairment (MCI). This study examined types of simulated medication-taking errors in cognitively normal older adults (CN; n = 131), single domain amnestic MCI (sdMCI, n = 91), and multi-domain MCI (mdMCI, n = 44). Errors were measured using the medication management ability assessment (MMAA). Methods: 266 participants seen for neuropsychological evaluation (94.4% White, 57.9% female, average age = 72, average education = 14 years) completed the MMAA (version 4.1), a performance-based task of medication management. Group differences in MMAA total scores, accuracy, and error types were evaluated using Kruskall-Wallis H tests. This study was the first to explore a newly operationalized error, perseverations, caused by taking a specific dose ≥2 times during the simulation. Results: CN and sdMCI groups had higher MMAA total scores than individuals with mdMCI, indicating better overall performance. The mdMCI group made a higher number of omission errors (missed pills) than other groups, but no differences were found for commission errors (extra pills). The sdMCI group made more perseverative errors compared to the CN group. Conclusions: Individuals with mdMCI made more simulated medication management errors than CN and sdMCI groups, indicating that they may be most vulnerable to difficulties in medication management. In contrast, sdMCI individuals were more likely to make perseverative errors, which may reflect a tendency towards overcompensation of memory loss. Future studies should assess whether MMAA performance is associated with patterns of real-world medication-taking in more diverse samples of older adults.

Compensatory Strategy Intervention: What Older Patients Want and Why.

OBJECTIVE: Compensatory strategies can improve performance of instrumental activities of daily living in people with cognitive impairment. This study investigated patient interest in compensatory strategy interventions and preference for various intervention formats. METHODS: Semi-structured qualitative interviews with 38 older adults with cognitive impairment queried motivation to improve strategy use and interest in intervention formats/delivery methods. Two coders used thematic analysis to determine rates of interest in each intervention type and explore patient-reported barriers and facilitators to motivation and intervention models. RESULTS: Most of the samples reported motivation to enhance compensatory strategy use. Degree of motivation was driven by current experiences with strategy use, perceived benefit of potential changes, intrinsic desire to improve life and self, and current perceived need. The vast majority were interested in hour-long, multi-session, instructor-led interventions. Just over half of the sample was interested in a self-directed virtual program, and just under half was interested in involving family/friends. Facilitators and barriers to interest in intervention formats and delivery methods varied based on participants' previous experiences, preferred learning style, content, and time commitment of the intervention, and perceived current need for intervention. One-fifth of the sample expressed no interest in any intervention type, though they expressed openness to assistance in the future as needed. CONCLUSIONS: Older adults with cognitive impairment are generally motivated to enhance their compensatory strategy use. Clinicians/researchers designing compensatory strategy interventions should consider instructor-led formats, present individualized benefits of interventions, and demonstrate the benefits of both preventative and remedial intervention to optimize patient engagement.

Anticholinergic and sedative medication use in older patients with cognitive concerns.

BACKGROUND: Anticholinergic (AC) and sedative medications are a risk factor for cognitive impairment. This study sought to characterize AC and sedative use in older patients seen for outpatient neuropsychological evaluation and evaluate their associations with different cognitive domains. We hypothesized that AC and sedative use would be associated with worse attention/processing speed (AP), executive functioning (EF), and memory. METHODS: We conducted a cross-sectional chart review of 392 patients (mean [M] age = 72 ± 7.7 years, range = 54-91). Medications were characterized by number of AC medications (≥1 on the Anticholinergic Cognitive Burden Scale [ACB]), number of sedative medications, and polypharmacy (≥5 daily medications). Demographically adjusted composites were calculated for AP, EF, and memory. Bivariate Pearson correlations assessed relationships between medication use and cognition. Multivariate linear regressions evaluated significant medication-cognition associations, controlling for total medications, medical comorbidities, and estimated premorbid cognitive functioning. RESULTS: Polypharmacy was common (80%; n = 314). Most patients (70%; n = 275) used ≥1 sedative medications (range = 0-9). Over half (63%; n = 248) used ≥1 AC drugs (range = 0-7), yet ACB scores were ≤2 in 74% of patients. Sedative use was negatively correlated with AP (r = -0.134, p = 0.008) and EF (r = -0.105, p = 0.04). ACB scores were negatively correlated with AP (r = -0.106, p = 0.037). Sedatives and a priori covariates significantly predicted AP performance (R2 = 0.127, p < 0.001); using more sedative medications was uniquely associated with worse AP (ß = -0.426, p = 0.049). No significant associations were found with memory. CONCLUSION: AC and sedative medications and polypharmacy were prevalent in this sample of older patients. Though both drug classes had negative relationships with AP and EF, sedatives had a particularly negative association with AP. Contrary to our hypotheses, memory was not associated with medication use; however, anticholinergic burden was low within the sample, and AP and EF deficits may masquerade as memory problems.

Association between neuropsychological assessment and amyloid status in a clinical setting.

OBJECTIVE: Large research cohorts show robust associations between neuropsychological tests and Alzheimer's disease (AD) biomarkers, but studies in clinical settings are limited. The increasing availability of AD biomarkers to the practicing clinician makes it important to understand the relationship between comprehensive clinical neuropsychological assessment and biomarker status. This study examined concordance between practicing clinical neuropsychologists' diagnostic impressions and AD biomarker status in patients seen at an outpatient medical center, with a secondary aim of defining the characteristics of discordant cases. METHOD: Participants (N = 79) seen for clinical neuropsychological assessment who subsequently underwent lumbar puncture or amyloid positron emission tomography imaging were identified via retrospective chart review. Concordance between clinical neuropsychological diagnosis (non-AD, indeterminate, possible/probable AD) and AD biomarker status (negative, indeterminate, positive) was determined. Individual test score data were used to examine between-group differences based on amyloid status. RESULTS: AD biomarker positive and negative patients did not differ on individual neuropsychological tests after correcting for multiple comparisons, though the small number of AD biomarker indeterminate individuals performed better than biomarker positive patients. However, there was 76.7% concordance between neuropsychologists' diagnostic impressions and AD biomarker status (88% sensitivity and 55% specificity of neuropsychological assessment in detecting AD biomarker status). AD biomarker negative patients diagnosed as possible/probable AD (discordant) versus non-AD (concordant) had significantly lower Neuropsychological Assessment Battery Story Delayed Recall, higher Wechsler Adult Intelligence Scale-Fourth Edition Coding, and higher Trail-Making A (i.e., an amnestic memory profile). CONCLUSIONS: Comprehensive neuropsychological assessment showed modest concordance with AD biomarker status in patients seen in an outpatient medical center for routine clinical care. Low specificity for the clinical diagnosis of AD could be explained by the multiplicity of etiologies that cause memory impairment (i.e., TAR DNA-binding protein 43, suspected non-AD pathology).

Effect of cognitive status on self-regulatory driving behavior in older adults: an assessment of naturalistic driving using in-car video recordings.

Previous findings that older drivers engage in strategic self-regulatory behaviors to minimize perceived safety risks are primarily based on survey reports rather than actual behavior. This study analyzed in-car video recording of naturalistic driving of 18 patients with Alzheimer disease (AD) and 20 age-matched controls in order to (1) characterize self-regulatory behaviors engaged by older drivers and (2) assess how behaviors change with cognitive impairment. Only participants who were rated "safe" on a prior standardized road test were selected for this study. Both groups drove primarily in environments that minimized the demands on driving skill and that incurred the least risk for involvement in major crashes. Patients with AD displayed further restrictions of driving behavior beyond those of healthy elderly individuals, suggesting additional regulation on the basis of cognitive status. These data provide critical empirical support for findings from previous survey studies indicating an overall reduction in driving mobility among older drivers with cognitive impairment.

Self-reported depressive syndromes in mild cognitive impairment and mild Alzheimer's disease.

BACKGROUND: There is suggestion that self-reported depressive syndromes can independently manifest in the general population as cognitive/affective or somatic/vegetative. The Beck Depression Inventory, 2nd edition (BDI-II), a self-report measure of depressive symptoms, has been shown to support this two-factor structure. However, this finding has not been examined in an older adult sample with cognitive impairment. In order to determine whether older adults with cognitive impairments exhibit similarly independent cognitive/affective and somatic/vegetative depressive syndromes, we explored the factor structure of the BDI-II in this population. METHODS: Participants were 228 older adults (mean age = 74, SD = 7.9) diagnosed with mild cognitive impairment (MCI; n = 137) or early Alzheimer's disease (n = 85), who completed the BDI-II as part of an outpatient neuropsychological evaluation. Exploratory principal component factor analysis with direct Oblimin rotation was conducted, and a two-factor solution was specified based on our theoretical conceptualization of the cognitive/affective and somatic/vegetative items from the scale. RESULTS: The first factor represented cognitive/affective symptoms of depression (e.g. self-dislike, pessimism, worthlessness), and accounted for 36% of the variance. Adding the second factor, reflecting somatic/vegetative items (e.g. sleep and appetite changes, loss of energy), accounted for an additional 6.8% of the variance. CONCLUSION: Results supported the presence of two distinct depressive syndromes, cognitive/affective and somatic/vegetative symptoms. Thus, cognitively impaired older adults report mood symptoms relatively similarly to younger and midlife adults. This supports the validity of self-reported mood in this group, and the results may have implications for psychiatric treatment in this population.

A comparison of cognitive performances based on differing rates of DNA methylation GrimAge acceleration among older men and women.

Cognitive heterogeneity increases with age rendering sex differences difficult to identify. Given established sex differences in biological aging, we examined whether comparisons of men and women on neuropsychological test performances differed as a function of age rate. Data were obtained from 1921 adults enrolled in the 2016 wave of the Health and Retirement Study. The residual from regressing the DNA methylation GrimAge clock on chronological age was used as the measure of aging rate. Slow and fast age rates were predefined as 1 standard deviation below or above the sex-specific mean rates, respectively. ANCOVAs were used to test group differences in test performances. Pairwise comparisons revealed that slow aging men outperformed fast aging women (and vice versa) on measures of executive function/speed, visual memory and semantic fluency; however, when groups were matched by aging rates, no significant differences remained. In contrast, women, regardless of their aging rates, education or depressive symptoms maintained their advantage on verbal learning and memory. Implications for research on sex differences in cognitive aging are discussed.

Comparison of personality characteristics on the bear-fedio inventory between patients with epilepsy and those with non-epileptic seizures.

This study used the Bear-Fedio Personality Inventory (BFI) to compare 41 individuals with temporal lobe epilepsy (TLE) and 37 with psychogenic non-epileptic seizures (NES). Both groups exhibited similar elevations on the BFI, although TLE individuals show greater endorsement of at least one hypergraphia symptom, as compared with those with NES. The correlates of the BFI with demographic and seizure characteristics differed between the groups. These results argue against a specific TLE personality syndrome and suggest that personality characteristics may be related to the experience of having repeated seizures, rather than the specific underlying pathophysiology of temporal lobe epilepsy.

Depression symptoms as a function of duration of intractable or controlled epilepsy.

We examined if depression symptoms in patients with intractable (IE) or controlled epilepsy (CE) differ and how long after onset of epilepsy these effects would be most pronounced. The NDDI-E was administered to all outpatients (n=358) seen in a comprehensive epilepsy program clinic over a two-year period. Patients who met inclusion criteria (n=223) completed a total of 431 NDDI-E surveys over this time. Patients with a diagnosis of IE (n=72) or CE (n=151) were compared as a function of time since their epilepsy onset, segmented into 10-year epochs. Depression symptoms were higher in patients with IE compared to CE at 10-<20 years and did not differ at other time points. This study reveals differences in depression symptoms as a function of duration of epilepsy. Attending to the dynamic nature of depression symptoms in different epochs of epilepsy may be an important treatment target in patients with epilepsy.

The complementary utility of cognitive testing and the medication management ability assessment in older adults.

OBJECTIVE: Older adults are susceptible to cognitive declines that may limit independence. Though neuropsychologists opine about risk of functional decline, the degree to which cognitive testing and in-office simulations approximate everyday behavior is unclear. We assessed the complementary utility of cognitive testing and the face-valid Medication Management Ability Assessment (MMAA) to predict medication management among older adults. METHOD: This was a retrospective study of 234 older adults (age = 72 ± 7.7 years; 59% women) who completed the MMAA during outpatient neuropsychological evaluations. Based on comprehensive clinical assessment, most participants (n = 186) were independent in medication management, while 48 received assistance. Demographically adjusted composite scores were derived for attention/processing speed (A/PS), executive functioning (EF), visuospatial/constructional ability (VC), language, and memory domains. Univariate differences in cognition were examined across Assisted versus Independent groups. Logistic regression assessed which cognitive domains independently predicted group status. The incremental value of the MMAA was assessed, holding uniquely associated cognitive test scores constant. RESULTS: Those receiving assistance with medication management performed worse across all neurocognitive domains and the MMAA compared with independent counterparts. EF was the only unique cognitive predictor of medication management status. When modeled alone, EF and MMAA performance correctly classified 79.5% and 80.8% of cases, respectively. When modeled together, both were independently associated with medication management status and correctly classified 83.3% of cases. CONCLUSIONS: EF uniquely predicted medication management status beyond other cognitive domains. The MMAA provided complementary predictive utility. Concurrent interpretation of executive functioning and MMAA performance is advised when assessing older adults suspected of medication mismanagement.

The Clinical Utility and Ecological Validity of the Medication Management Ability Assessment in Older Adults with and without Dementia.

OBJECTIVE: Older adults are susceptible to medication nonadherence, which may signify functional decline. Thus, performance-based proxies of medication-taking behavior may help diagnose dementia. We assessed the Medication Management Ability Assessment's (MMAA) clinical utility and ecological validity. METHOD: This was a retrospective chart review of 180 outpatients (age = 72 ± 8 years) who completed the MMAA during clinical evaluations. Forty-seven were cognitively normal (CN), 103 had mild cognitive impairment (MCI), and 30 had dementia. Most (136) were independent in medication management, whereas 28 were assisted and 16 were dependent. Kruskal-Wallis tests assessed whether MMAA scores differed by diagnosis and independence. Receiver operating characteristic (ROC) analyses identified diagnostic cut-offs. Classification accuracy estimates were derived. RESULTS: MMAA performance differed across diagnosis as expected (p's < .001). Those who were independent in medication management outperformed assisted and dependent counterparts (p's < .001). Assisted and dependent cases were no different. At a cut-off = 23, the MMAA was good-to-strong in distinguishing dementia from CN cases (Sn = 0.96, Sp = 0.83), dementia from MCI (Sn = 0.70, Sp = 0.83), and dementia from functionally unimpaired cases (Sn = 0.78, Sp = 0.83). At a cut-off = 27, it had good sensitivity but weaker specificity when distinguishing both MCI and all cognitively impaired patients (MCI and dementia) from CN cases (Sn = 0.81, Sp = 0.66 and Sn = 0.81, Sp = 0.72, respectively). CONCLUSIONS: The MMAA has ecological validity and clinical utility in identifying dementia. Its inclusion in neuropsychological practice may be especially useful when medication mismanagement is suspected.

Video feedback intervention for cognitively impaired older drivers: A randomized clinical trial.

INTRODUCTION: This clinical trial aimed to determine whether in-car video feedback about unsafe driving events (UDE) to cognitively impaired older drivers and family members leads to a reduction in such driving behaviors. METHODS: We randomized 51 cognitively impaired older drivers to receive either (1) a weekly progress report with recommendations and access to their videos, or (2) video monitoring alone without feedback over 3 months. RESULTS: UDE frequency/1000 miles was reduced by 12% in feedback (rate ratio [RR] = 0.88, 95% confidence interval [CI] = .58-1.34), while remaining constant with only monitoring (RR = 1.01, 95% CI = .68-1.51). UDE severity/1000 miles was reduced by 37% in feedback (RR = 0.63, 95% CI = .31-1.27), but increased by 40% in monitoring (RR = 1.40, 95% CI = .68-2.90). Cognitive impairment moderated intervention effects (P = .03) on UDE frequency. DISCUSSION: Results suggest the potential to improve driving safety among mild cognitively impaired older drivers using a behavior modification approach aimed at problem behaviors detected in their natural driving environment.
