Sex-specific neuropsychological correlates of apathy and depression across neurodegenerative disorders.

BACKGROUND: Apathy and depression are common neuropsychiatric symptoms across neurodegenerative disorders and are associated with impairment in several cognitive domains, yet little is known about the influence of sex on these relationships. OBJECTIVES: We examined the relationship between these symptoms with neuropsychological performance across a combined cohort with mild or major neurodegenerative disorders, then evaluated the impact of sex. DESIGN, SETTING AND PARTICIPANTS: We conducted a cohort analysis of participants in the COMPASS-ND study with mild cognitive impairment (MCI), vascular MCI, Alzheimer's disease, mixed dementia, Parkinson's disease, frontotemporal dementia, and cognitively unimpaired (CU) controls. MEASUREMENTS: Participants with neurodegenerative disease and CU controls were stratified by the presence (severity ≥1 on Neuropsychiatric Inventory Questionnaire) of either depressive symptoms alone, apathy symptoms alone, both symptoms, or neither. A neuropsychological battery evaluated executive function, verbal fluency, verbal learning, working memory, and visuospatial reasoning. Analysis of covariance was used to assess group differences with age, sex, and education as covariates. RESULTS: Groups included depressive symptoms only (n = 70), apathy symptoms only (n = 52), both (n = 68), or neither (n = 262). The apathy and depression + apathy groups performed worse than the neither group on tests of working memory (t(312)  = -2.4, p = 0.02 and t(328)  = -3.8, p = 0.001, respectively) and visuospatial reasoning (t(301)  = -2.3, p = 0.02 and t(321)  = -2.6, p = 0.01, respectively). The depression, apathy, and depression + apathy groups demonstrated a similar degree of impairment on tests of executive function, processing speed, verbal fluency, and verbal learning when compared to participants without apathy or depression. Sex-stratified analyses revealed that compared to the male neither group, the male apathy and depression + apathy groups were impaired broadly across all cognitive domains except for working memory. Females with depression alone showed deficits on tests of executive function (t(166)  = 2.4, p = 0.01) and verbal learning (t(167)  = -4.3, p = 0.001) compared to the female neither group. CONCLUSIONS: This study demonstrated that in neurodegenerative diseases, apathy with or without depression in males was associated with broad cognitive impairments. In females, depression was associated with deficits in executive function and verbal learning. These findings highlight the importance of effectively treating apathy and depression across the spectrum of neurodegenerative disorders with the goal of optimizing neuropsychological outcomes.

A Systematic Review of the Risks of Motor Vehicle Crashes Associated with Psychiatric Disorders.

OBJECTIVE: Psychiatric disorders and their treatments have the potential to adversely impact driving skills. However, it is unclear to what extent this poses a public health risk by increasing the risk of motor vehicle crashes (MVCs). The aim of this systematic review was to synthesize and critically appraise evidence on the risk of MVC for drivers with psychiatric disorders. METHOD: We conducted a systematic review of the MVC risk associated with psychiatric disorders using seven databases in November 2019. Two reviewers examined each study and extracted data. The National Heart, Lung, and Blood Institute Quality Assessment tools were used to assess each study's quality of evidence. RESULTS: We identified 24 studies that met the inclusion criteria, including eight cohort, 10 case-control, and six cross-sectional designs. Quality assessment ratings were "Good" for four studies, "Fair" for 10, and "Poor" for 10. Self-report or questionnaires were used in place of objective measures of either MVC, psychiatric disorder, or both in 12 studies, and only seven adjusted for driving exposure. Fifteen studies reported an increased risk of MVC associated with psychiatric disorders, and nine did not. There was no category of disorder that was consistently associated with increased MVC risk. CONCLUSION: The available evidence is mixed, not of high quality, and does not support a blanket restriction on drivers with psychiatric disorder. An individualized approach, as recommended by international guidelines, should continue. Further research should include objective assessments of psychiatric disorders and MVC risk and adjust for driving exposure.

Developing the Driving and Dementia Roadmap: a knowledge-to-action process.

OBJECTIVES: Despite three decades of research, gaps remain in meeting the needs of people with dementia and their family/friend carers as they navigate the often-tumultuous process of driving cessation. This paper describes the process of using a knowledge-to-action (KTA) approach to develop an educational web-based resource (i.e. toolkit), called the Driving and Dementia Roadmap (DDR), aimed at addressing some of these gaps. DESIGN: Aligned with the KTA framework, knowledge creation and action cycle activities informed the development of the DDR. These activities included systematic reviews; meta-synthesis of qualitative studies; interviews and focus groups with key stakeholders; development of a Driving and Dementia Intervention Framework (DD-IF); and a review and curation of publicly available resources and tools. An Advisory Group comprised of people with dementia and family carers provided ongoing feedback on the DDR's content and design. RESULTS: The DDR is a multi-component online toolkit that contains separate portals for current and former drivers with dementia and their family/friend carers. Based on the DD-IF, various topics of driving cessation are presented to accommodate users' diverse stages and needs in their experiences of decision-making and transitioning to non-driving. CONCLUSION: Guided by the KTA framework that involved a systematic and iterative process of knowledge creation and translation, the resulting person-centered, individualized and flexible DDR can bring much-needed support to help people with dementia and their families maintain their mobility, community access, and social and emotional wellbeing during and post-driving cessation.

A GPS-Based Framework for Understanding Outdoor Mobility Patterns of Older Adults with Dementia: An Exploratory Study.

INTRODUCTION: An active lifestyle may protect older adults from cognitive decline. Yet, due to the complex nature of outdoor environments, many people living with dementia experience decreased access to outdoor activities. In this context, conceptualizing and measuring outdoor mobility is of great significance. Using the global positioning system (GPS) provides an avenue for capturing the multi-dimensional nature of outdoor mobility. The objective of this study is to develop a comprehensive framework for comparing outdoor mobility patterns of cognitively intact older adults and older adults with dementia using passively collected GPS data. METHODS: A total of 7 people with dementia (PwD) and 8 cognitively intact controls (CTLs), aged 65 years or older, carried a GPS device when travelling outside their homes for 4 weeks. We applied a framework incorporating 12 GPS-based indicators to capture spatial, temporal, and semantic dimensions of outdoor mobility. RESULTS: Despite a small sample size, the application of our mobility framework identified several significant differences between the 2 groups. We found that PwD participated in more medical-related (Cliff's Delta = 0.71, 95% CI: 0.34-1) and fewer sport-related (Cliff's Delta = -0.78, 95% CI: -1 to -0.32) activities compared to the cognitively intact CTLs. Our results also suggested that longer duration of daily walking time (Cliff's Delta = 0.71, 95% CI: 0.148-1) and longer outdoor activities at night, after 8 p.m. (Hedges' g = 1.42, 95% CI: 0.85-1.09), are associated with cognitively intact individuals. CONCLUSION: Based on the proposed framework incorporating 12 GPS-based indicators, we were able to identify several differences in outdoor mobility in PwD compared with cognitively intact CTLs.

Exercise priming with transcranial direct current stimulation: a study protocol for a randomized, parallel-design, sham-controlled trial in mild cognitive impairment and Alzheimer's disease.

BACKGROUND: Transcranial direct current stimulation (tDCS) is a non-invasive type of brain stimulation that uses electrical currents to modulate neuronal activity. A small number of studies have investigated the effects of tDCS on cognition in patients with Mild Cognitive Impairment (MCI) and Alzheimer's disease (AD), and have demonstrated variable effects. Emerging evidence suggests that tDCS is most effective when applied to active brain circuits. Aerobic exercise is known to increase cortical excitability and improve brain network connectivity. Exercise may therefore be an effective, yet previously unexplored primer for tDCS to improve cognition in MCI and mild AD. METHODS: Participants with MCI or AD will be randomized to receive 10 sessions over 2 weeks of either exercise primed tDCS, exercise primed sham tDCS, or tDCS alone in a blinded, parallel-design trial. Those randomized to an exercise intervention will receive individualized 30-min aerobic exercise prescriptions to achieve a moderate-intensity dosage, equivalent to the ventilatory anaerobic threshold determined by cardiopulmonary assessment, to sufficiently increase cortical excitability. The tDCS protocol consists of 20 min sessions at 2 mA, 5 times per week for 2 weeks applied through 35 cm2 bitemporal electrodes. Our primary aim is to assess the efficacy of exercise primed tDCS for improving global cognition using the Montreal Cognitive Assessment (MoCA). Our secondary aims are to evaluate the efficacy of exercise primed tDCS for improving specific cognitive domains using various cognitive tests (n-back, Word Recall and Word Recognition Tasks from the Alzheimer's Disease Assessment Scale-Cognitive subscale) and neuropsychiatric symptoms (Neuropsychiatric Inventory). We will also explore whether exercise primed tDCS is associated with an increase in markers of neurogenesis, oxidative stress and angiogenesis, and if changes in these markers are correlated with cognitive improvement. DISCUSSION: We describe a novel clinical trial to investigate the effects of exercise priming before tDCS in patients with MCI or mild AD. This proof-of-concept study may identify a previously unexplored, non-invasive, non-pharmacological combination intervention that improves cognitive symptoms in patients. Findings from this study may also identify potential mechanistic actions of tDCS in MCI and mild AD. TRIAL REGISTRATION: Clinicaltrials.gov, NCT03670615 . Registered on September 13, 2018.

Subjective Experiences of Driving Cessation and Dementia: A Meta-Synthesis of Qualitative Literature.

Objectives: To review qualitative research on the specific challenges and strategies that relate to driving cessation for older adults with dementia, from the perspectives of key informant groups.Method: A meta-synthesis of qualitative studies was conducted. Structured inclusion criteria were applied to screen 616 titles and abstracts, and 9 qualitative studies were included, published from 2002 to 2016. Descriptive themes were identified using content analysis and synthesized to generate analytic themes.Results: The study samples and methodologies represented a diverse range. Cross-cutting themes on experiences of driving cessation for people with dementia are the: importance of open communication and autonomy in decision-making, and advanced planning to connect people with resources; significance of relationships; importance of providing support for the impact of cessation on identity and emotional wellbeing; and benefit of individualizing supportive approaches.Conclusion: This review identifies some important areas for consideration when designing supportive programs to address driving.Clinical Implications: Interventions to support driving cessation for people with dementia should prioritize support for communication, advanced planning, and emotional effects of stopping driving.

Risk of Motor Vehicle Collision or Driving Impairment After Traumatic Brain Injury: A Collaborative International Systematic Review and Meta-Analysis.

OBJECTIVE: To synthesize knowledge of the risk of motor vehicle collision (MVC) following a traumatic brain injury (TBI) and the associated risk of driving impairment, as measured by on-road tests, computerized simulators, and self-reported or state-recorded driving records. METHODS: Our international team searched 7 databases for studies published between 1990 and 2015 of people with TBI, controls, and data concerning either MVC or driving impairment. The included articles examined the risk of MVC among people with TBI; we excluded studies that examined the risk of having a TBI associated with being involved in an MVC. RESULTS: From 13 578 search results, we included 8 studies involving 1663 participants with TBI and 4796 controls. We found no significant difference in the risk of MVC (odds ratio = 1.24, 95% confidence interval = 0.80-1.91, P = .34). When we restricted the analysis to self-report, the risk of MVC was higher for those without a TBI (odds ratio = 1.63, 95% confidence interval = 1.21-2.22, P = .002). In contrast, participants with TBI consistently performed worse during on-road assessments and had more problems with vehicular control. CONCLUSION: Limitations of reviewed studies included small sample sizes, failure to specify TBI severity or time postinjury, and absence of objective measures of risk. Findings concerning the relationship between TBIs from non-MVC causes and crash risk are, therefore, inconclusive and do not provide evidence for major changes to existing clinical guidelines for driving with TBI.

An International Approach to Enhancing a National Guideline on Driving and Dementia.

PURPOSE OF REVIEW: The purpose of this study was to update a national guideline on assessing drivers with dementia, addressing limitations of previous versions which included a lack of developmental rigor and stakeholder involvement. METHODS: An international multidisciplinary team reviewed 104 different recommendations from 12 previous guidelines on assessing drivers with dementia in light of a recent review of the literature. Revised guideline recommendations were drafted by consensus. A preliminary draft was sent to specialist physician and occupational therapy groups for feedback, using an a priori definition of 90% agreement as consensus. RECENT FINDINGS: The research team drafted 23 guideline recommendations, and responses were received from 145 stakeholders. No recommendation was endorsed by less than 80% of respondents, and 14 (61%) of the recommendations were endorsed by more than 90%.The recommendations are presented in the manuscript. The revised guideline incorporates the perspectives of consensus of an expert group as well as front-line clinicians who regularly assess drivers with dementia. The majority of the recommendations were based on evidence at the level of expert opinion, revealing gaps in the evidence and future directions for research.

Computer-Based Driving in Dementia Decision Tool With Mail Support: Cluster Randomized Controlled Trial.

BACKGROUND: Physicians often find significant challenges in assessing automobile driving in persons with mild cognitive impairment and mild dementia and deciding when to report to transportation administrators. Care must be taken to balance the safety of patients and other road users with potential negative effects of issuing such reports. OBJECTIVE: The aim of this study was to assess whether a computer-based Driving in Dementia Decision Tool (DD-DT) increased appropriate reporting of patients with mild dementia or mild cognitive impairment to transportation administrators. METHODS: The study used a parallel-group cluster nonblinded randomized controlled trial design to test a multifaceted knowledge translation intervention. The intervention included a computer-based decision support system activated by the physician-user, which provides a recommendation about whether to report patients with mild dementia or mild cognitive impairment to transportation administrators, based on an algorithm derived from earlier work. The intervention also included a mailed educational package and Web-based specialized reporting forms. Specialists and family physicians with expertise in dementia or care of the elderly were stratified by sex and randomized to either use the DD-DT or a control version of the tool that required identical data input as the intervention group, but instead generated a generic reminder about the reporting legislation in Ontario, Canada. The trial ran from September 9, 2014 to January 29, 2016, and the primary outcome was the number of reports made to the transportation administrators concordant with the algorithm. RESULTS: A total of 69 participating physicians were randomized, and 36 of these used the DD-DT; 20 of the 35 randomized to the intervention group used DD-DT with 114 patients, and 16 of the 34 randomized to the control group used it with 103 patients. The proportion of all assessed patients reported to the transportation administrators concordant with recommendation did not differ between the intervention and the control groups (50% vs 49%; Z=-0.19, P=.85). Two variables predicted algorithm-based reporting-caregiver concern (odds ratio [OR]=5.8, 95% CI 2.5-13.6, P<.001) and abnormal clock drawing (OR 6.1, 95% CI 3.1-11.8, P<.001). CONCLUSIONS: On the basis of this quantitative analysis, in-office abnormal clock drawing and expressions of concern about driving from caregivers substantially influenced physicians to report patients with mild dementia or mild cognitive impairment to transportation administrators, but the DD-DT tool itself did not increase such reports among these expert physicians.

Update on the Risk of Motor Vehicle Collision or Driving Impairment with Dementia: A Collaborative International Systematic Review and Meta-Analysis.

Guidelines that physicians use to assess fitness to drive for dementia are limited in their currency, applicability, and rigor of development. Therefore, we performed a systematic review to determine the risk of motor vehicle collisions (MVCs) or driving impairment caused by dementia, in order to update international guidelines on driving with dementia. Seven literature databases (MEDLINE, CINAHL, Embase, etc.) were searched for all research studies published after 2004 containing participants with mild, moderate, or severe dementia. From the retrieved 12,860 search results, we included nine studies in this analysis, involving 378 participants with dementia and 416 healthy controls. Two studies reported on self-/informant-reported MVC risk, one revealing a four-fold increase in MVCs per 1,000 miles driven per week in 3 years prior, and the other showing no statistically significant increase over the same time span. We found medium to large effects of dementia on driving abilities in six of the seven recent studies that examined driving impairment. We also found that persons with dementia were much more likely to fail a road test than healthy controls (RR: 10.77, 95% CI: 3.00-38.62, z = 3.65, p < 0.001), with no significant heterogeneity (χ2 = 1.50, p = 0.68, I2 = 0%) in a pooled analysis of four studies. Although the limited data regarding MVCs are equivocal, even mild stages of dementia place patients at a substantially higher risk of failing a performance-based road test and of demonstrating impaired driving abilities on the road.

A systematic review of intervention approaches for driving cessation in older adults.

OBJECTIVE: The aim of this project was to review the literature on interventions aimed at facilitating driving cessation in older adults, with and without dementia. METHODS: A literature search was performed using the databases MEDLINE, CINAHL, Cochrane Central, Embase, and PsycINFO, from 1994 to September 2014. Two independent raters screened articles for inclusion and extracted study data. We only included articles if they directly addressed the topic of intervention approaches to facilitate the process of driving cessation in older adults or to support the adaptation of older adults who have had to stop driving and included a control group. RESULTS: Of an initial 477 unique records identified, 111 pertained to driving cessation in older adults, and only three articles were controlled trials of intervention approaches related to driving cessation. One article described an intervention for retired drivers with dementia, while another was aimed at caregivers of drivers with dementia, and the third included retired and retiring drivers without dementia. Outcomes such as reduced depressive symptoms, increased trips out of home, and efficacy in dealing with the driving cessation process were positive, but the specific outcome measures and magnitude of effects varied across studies. CONCLUSIONS: Although the results summarized in this review point toward potentially promising effects of interventions for facilitating driving cessation in older adults, these findings must be interpreted with caution given the significant methodological limitations of the studies, including small samples, participant attrition, lack of blinding, and non-validated outcome measures.

Development of a decision-making tool for reporting drivers with mild dementia and mild cognitive impairment to transportation administrators.

BACKGROUND: Driving in persons with dementia poses risks that must be counterbalanced with the importance of the care for autonomy and mobility. Physicians often find substantial challenges in the assessment and reporting of driving safety for persons with dementia. This paper describes a driving in dementia decision tool (DD-DT) developed to aid physicians in deciding when to report older drivers with either mild dementia or mild cognitive impairment to local transportation administrators. METHODS: A multi-faceted, computerized decision support tool was developed, using a systematic literature and guideline review, expert opinion from an earlier Delphi study, as well as qualitative interviews and focus groups with physicians, caregivers of former drivers with dementia, and transportation administrators. The tool integrates inputs from the physician-user about the patient's clinical and driving history as well as cognitive findings, and it produces a recommendation for reporting to transportation administrators. This recommendation is translated into a customized reporting form for the transportation authority, if applicable, and additional resources are provided for the patient and caregiver. CONCLUSIONS: An innovative approach was needed to develop the DD-DT. The literature and guideline review confirmed the algorithm derived from the earlier Delphi study, and barriers identified in the qualitative research were incorporated into the design of the tool.

Career Interests of Canadian Psychiatry Residents: What Makes Residents Choose a Research Career?

OBJECTIVES: Training future clinician-researchers remains a challenge faced by Canadian psychiatry departments. Our objectives were to determine the prevalence of residents interested in pursuing research and other career options as part of their practice, and to identify the factors associated with interest in research. METHOD: Data from a national online survey of 207 Canadian psychiatry residents from a total of 853 (24.3% response rate) were examined. The main outcome was interest in research as part of residents' future psychiatrist practice. Bivariate and multivariate analyses were performed to identify demographic and vocational variables associated with research interest. RESULTS: Interest in research decreases by 76% between the first and fifth year of psychiatry residency (OR 0.76 per year, 95% CI 0.60 to 0.97). Training in a department with a residency research track did not correlate with increased research interest (χ2 = 0.007, df = 1, P = 0.93). CONCLUSIONS: Exposing and engaging psychiatry residents in research as early as possible in residency training appears key to promoting future research interest. Psychiatry residency programs and research tracks could consider emphasizing research training initiatives and protected research time early in residency.

Practice eligible route for certification in geriatric psychiatry: why some Canadian psychiatrists are disinterested in writing the RCPSC subspeciality examination?

Geriatric psychiatry was officially recognized as a subspecialty by the Royal College of Physicians and Surgeons of Canada (RCPSC) in 2009, with the first RCPSC exam written in 2013 (Andrew and Shea, 2010). The unique mental health needs of Canadians' seniors requires geriatric psychiatrists trained to address them (Herrmann, 2004), but current rates of recruitment in informal fellowship programs have been inadequate (Bragg et al., 2012). One hope of subspeciality recognition was to increase recruitment in Canada, but there have been some challenges in accrediting psychiatrists already caring for older adults. Many currently practicing geriatric psychiatrists have elected to take the Royal College examination, with >120 graduates in the first year, 2013, but others have been more ambivalent. In this letter, we perform a preliminary exploration of the prevalence and correlates of disinterest in completing the RCPSC geriatric psychiatry examination.

Evaluation of a National Online Educational Program in Geriatric Psychiatry.

OBJECTIVE: This study provides evaluation results of an online study group (OSG) for geriatric psychiatry continuing professional development. METHODS: The OSG is an interactive, expert-facilitated, asynchronous educational experience for psychiatrists and residents in Canada. A retrospective web survey assessed self-efficacy, knowledge in geriatric psychiatry, comfort with online learning, and perceived effectiveness of the instructional methods. Wilcoxon signed-rank tests and descriptive statistics were calculated. RESULTS: Twenty-nine (of 50) participants (58 %) completed the questionnaire. Although only 48 % of respondents reported improved perceived knowledge, 79 % reported improved efficacy beliefs, and 76 % reported improved comfort with online learning. Most (79 %) would consider taking OSG again, and 93 % would recommend it to others. CONCLUSIONS: The OSG was well-received, with greater benefits for self-efficacy with the material and comfort with online learning than for perceived knowledge itself. Further research is needed to ascertain actual knowledge change in the context of online learning in medical education.

What Makes Residents Interested in Geriatric Psychiatry? A Pan-Canadian Online Survey of Psychiatry Residents.

OBJECTIVES: In spite of a rapidly increasing need, there remains a shortage of geriatric psychiatrists in North America. The factors associated with psychiatric residents' interest in geriatric psychiatry have not yet been examined in a nationally representative sample. DESIGN: Cross-sectional study. SETTING: Web-based online survey of Canadian psychiatry residents. PARTICIPANTS: 207 psychiatry residents (24.3% response rate). MEASUREMENTS: The main outcome was interest in becoming a geriatric psychiatrist. Bivariate and multivariate analyses were performed to better understand what demographic, educational, and vocational variables were associated with interest in becoming a geriatric psychiatrist. RESULTS: A number of respondents had an interest in becoming a geriatric psychiatrist (29.0%, N = 60); in doing a geriatric psychiatry fellowship (20.3%, N = 42); or an interest in doing geriatric psychiatry as a part of the clinical practice (60.0%, N = 124). Demographic characteristics (age, gender, ethnicity) did not correlate with interest in geriatric psychiatry. The variables most robustly associated with interest in geriatric psychiatry were: 1) completion of geriatric psychiatry rotation(s) before the third year of residency (OR: 5.13, 95% CI: 1.23-21.4); 2) comfort working with geriatric patients and their families (OR: 18.6, 95% CI: 2.09-165.3); 3) positive experiences caring for older adults prior to medical school (OR: 12.4, 95% CI: 1.07-144.5); and 4) the presence of annual conferences in the resident's field of interest (OR: 4.50, 95% CI: 1.12-18.2). CONCLUSION: Exposing medical students and junior psychiatry residents to clinical geriatric psychiatry rotations that increase comfort in working with older adults may be potential future strategies to improve recruitment of geriatric psychiatrists.

Developing physician consensus on the reporting of patients with mild cognitive impairment and mild dementia to transportation authorities in a region with mandatory reporting legislation.

OBJECTIVE: To establish consensus among dementia experts about which patients with mild cognitive impairment (MCI) or mild dementia should be reported to transportation authorities. METHODS: We conducted a literature review of predictors of driving safety in patients with dementia and combined these into 26 case scenarios. Using a modified Delphi technique, case scenarios were reviewed by 38 dementia experts (geriatric psychiatrists, geriatricians, cognitive neurologists and family physicians with expertise in elder care) who indicated whether or not they would report the patient in each scenario to regional transportation authorities and recommend a specialized on-road driving test. Scenarios were presented up to five times to achieve consensus, defined as 85% agreement, and discrepancies were discussed anonymously online. RESULTS: By the end of the fifth iteration, there was cumulative consensus on 18 scenarios (69%). The strongest predictors of decision to report were the combination of caregiver concern about the patient's driving and abnormal Clock Drawing Test, which accounted for 62% of the variance in decision to report at the same time as or without a road test (p <0.01). Based on these data, an algorithm was developed to guide physician decision-making about reporting patients with MCI or mild dementia to transportation authorities. CONCLUSION: This study supports existing international guidelines that recommend specialized on-road testing when driving safety is uncertain for patients with MCI and emphasizes the importance of assessing executive dysfunction and caregiver concern about driving.

Older Drivers Reduced Engagement in Distracting Behaviors Over a Six-Year Period: Findings From the Candrive Longitudinal Study.

OBJECTIVES: Baltes and Baltes' "selective optimization with compensation" model is pertinent to driving but evidence about the use of compensation using longitudinal designs is scarce. Therefore, we sought to determine if older drivers reduced their engagement in distracting behaviors while driving, over a 6-year period. METHODS: We used data captured over several annual assessments from a cohort of 583 drivers aged 70 and older to determine if their engagement in 12 distracting behaviors (e.g., listening to the radio, talking with passengers) declined over time. We adjusted our multivariable model for several potential confounders of the association between our outcome variable and time. RESULTS: Overall, and after adjustment for potential confounders, the participants reduced their engagement in distracting behaviors over the study period (odds ratio [OR] = 0.96, 95% confidence interval [CI] = 0.95-0.97). Baseline age was negatively associated with engagement in distracting behaviors (OR = 0.95, 95% CI = 0.94-0.96). Men engaged in more distracting behaviors than women (OR = 1.15, 95% CI = 1.03-1.27), as did participants living in the largest urban centers compared to participants living in the smallest areas (OR = 1.21, 95% CI = 1.04-1.41). The number of kilometers driven per year (for every 10,000 km) was positively associated with the proportion of distracting behaviors drivers engaged in (OR = 1.13, 95% CI = 1.08-1.19). DISCUSSION: Drivers in our cohort reduced their engagement in distracting behaviors over the study period. This suggests that older drivers adjust their driving over time, which aligns with age-related theories and models about compensation.

Pharmacological treatments for neuropsychiatric symptoms of dementia in long-term care: a systematic review.

BACKGROUND: Medications are frequently prescribed for neuropsychiatric symptoms (NPS) associated with dementia, although information on the efficacy and safety of medications for NPS specifically in long-term care (LTC) settings is limited. The objective of this study was to provide a current review of the efficacy and safety of pharmacological treatments for NPS in LTC. METHODS: We searched MEDLINE, EMBASE, PsychINFO, and the Cochrane Library for randomized controlled trials comparing medications with either placebo or other interventions in LTC. Study quality was described using the Cochrane collaboration risk of bias tool. The efficacy of medications was evaluated using NPS symptom rating scales. Safety was evaluated through rates of trial withdrawals, trial withdrawals due to adverse events, and mortality. RESULTS: A total of 29 studies met inclusion criteria. The most common medications evaluated in studies were atypical antipsychotics (N = 15), typical antipsychotics (N = 7), anticonvulsants (N = 4), and cholinesterase inhibitors (N = 3). Statistically significant improvements in NPS were noted in some studies evaluating risperidone, olanzapine, and single studies of aripiprazole, carbamazepine, estrogen, cyproterone, propranolol, and prazosin. Study quality was difficult to rate in many cases due to incomplete reporting of details. Some studies reported higher rates of trial withdrawals, adverse events, and mortality associated with medications. CONCLUSIONS: We conclude that there is limited evidence to support the use of some atypical antipsychotics and other medications for NPS in LTC populations. However, the generally modest efficacy and risks of adverse events highlight the need for the development of safe and effective pharmacological and non-pharmacological interventions for this population.

Nurse practitioners' preferences for online learning regarding driving and dementia.

ABSTRACT: With a growing population of older adults living with dementia in the community, nurse practitioners (NPs) are increasingly expected to address issues of medical fitness to drive (MFTD) and driving cessation within their clinical practice. With their expertise in clinical assessment and communication skills, NPs are well suited to this area of practice. Studies that examined MFTD and/or driving cessation suggest that NPs want and need further knowledge and training with this population. As part of our aim to develop an online educational program on driving and dementia for health care providers, including NPs, this mixed-methods study explored NPs' preferences regarding the format and content for the proposed online program. Results from an online survey completed by 90 NPs and interviews with six NPs highlighted key areas of focus for virtual modules, where communication strategies, tools to assess MFTD, and the reporting process for medically unfit drivers were emphasized. Reflecting on their team approach to care, participants in this study preferred a hybrid approach of asynchronous and synchronous learning delivery for this educational program. The next step will be to evaluate this program and its impact on both NP knowledge and skills in terms of its real-world application.
