The purpose of this study was to identify, map, summarize, and clarify the existing literature on the effects of behavioral and psychological symptoms of dementia (BPSD) an individual's autonomy across all types of dementia diagnoses. The study aimed to determine whether there is a correlation between BPSD and a decrease in a person's autonomy, as this relationship is important for improving dementia care through effective interventions. To achieve this goal, a scoping review was conducted using the Joanna Briggs Institute's methodology for scoping reviews and the PRISMA extension for scoping reviews checklist. The inclusion criteria were: (i) population: participants with a clinical diagnosis of any type of dementia; (ii) concept: examining the relationship between one or more neuropsychiatric symptoms or BPSD and the individual's autonomy; (iii) context: the progress of any type and any stage of dementia. The database search yielded 74 records, of which 41 fully met the pre-established eligibility criteria. Most studies in this review focused on participants with Alzheimer's disease and analysed their functional abilities. Most studies in this review showed significant outcomes regarding the impact of BPSD on a person's autonomy. The main BPSD investigated in the studies were depression, apathy, irritability, agitation, aggression, disinhibition, and lability. Apathy had a recurrent association with reduced autonomy in persons with dementia, while depression and psychosis were also found to have an impact on individuals' autonomy.

Objective: Develop and preliminarily validate recognition subtests for Form B of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS).

Method: 49 older adults with no cognitive impairment were compared to 53 individuals with a primary neurocognitive disorder (e.g., dementia, mild cognitive impairment, and traumatic brain injury) and 22 individuals with a primary psychiatric disorder (e.g., depression and anxiety) on three recognition subtests (list, story, and figure) for Form B of the RBANS in this observational study.

Results: The individuals with a primary neurocognitive disorder performed significantly poorer on most of the recognition scores compared to those with no cognitive impairment and those with a primary psychiatric disorder, with these latter two groups being largely comparable. In the entire sample, for the recognition subtests, education only correlated with figure recognition scores, and neither age nor gender influenced recognition scores. The RBANS indexes correlated with most of the recognition scores in the expected directions.

Conclusions: The group differences in performance on these recognition subtests preliminarily validate these scores on Form B, which were not previously available. Furthermore, these scores tended to not be influenced by age, education, or gender, although they were related to overall cognitive functioning. Additional validation is needed in larger, better clinically-defined, and more diverse samples. Nonetheless, these findings support the inclusion of the newly-developed Form B recognition subtests in future clinical practice and research settings to enhance the accuracy of diagnoses and treatment recommendations.

Background: Early detection of atypical dementia remains difficult partly because of the absence of specific cognitive screening tools. This creates undue delays in diagnosis and management. The Dépistage Cognitif de Québec (DCQ; dcqtest.org) was developed in French and later validated in participants with atypical syndromes. We report the validation of the English version.

Methods: This multicentre prospective validation study was conducted in 10 centers across Canada and the United States on 260 English-speaking participants aged over 50. We translated and modified the original French DCQ to add targeted stimuli to the Visusopatial Index and social cognition vignettes to the Behavioral Index. A backward translation was performed and equivalence between languages was assessed by administering both tests to 30 bilingual participants.

Results: Mean DCQ total score (out of 100) was 95.0 (SD = 3.6). Spearman's correlation coefficient showed a strong and significant correlation (r = 0.49, p < .001) with the Montreal Cognitive Assessment. Test-retest reliability was good (Spearman's coefficient = 0.72, p < .001) and interrater reliability, excellent (intraclass correlation = 0.97, p < .001). Normative data shown in percentiles were stratified by age and education for a population-based sample of 260 English-speaking controls aged between 50 and 87 years old.

Conclusions: Similar to the French version, the English DCQ proved to be a valid cognitive screening test. The original version was very sensitive to detect atypical dementias such as primary progressive aphasias, Alzheimer's disease' variants and syndromes along the frontotemporolobar degeneration spectrum. This 20-min test can be administered à la carte and offers an alternative to detailed comprehensive neuropsychological evaluations.

Objective: Precision child and youth mental healthcare has great potential to improve treatment success by tailoring interventions to individual needs. An innovative care pathway in a pediatric mental health outpatient clinic was designed to allow for neuropsychology data to be integrated in psychotherapeutic care. This paper describes the feasibility of this new pathway, including implementation outcomes, acceptability, and potential for future integration.

Method: The target population was outpatients 6-17 years old referred for individual treatment to a tertiary outpatient mental health (OPMH) clinic. The new care pathway was co-developed by neuropsychologists and mental health practitioners. A logic model was created to guide the evaluation, which was informed by the Reach Effectiveness Adoption Implementation Maintenance framework. As part of the logic model, a stepped assessment protocol was implemented, and reports on neuropsychological function were shared with patients, caregivers, and care providers. Evaluation data were collected from phone surveys, questionnaires, a focus group, and administrative records.

Results: Forty-two patients scheduled to receive therapy over a 6-month period were offered the opportunity to participate in the new care pathway and 39 (93%) agreed. Self-reported outcome data showed that 83% of patients and 94% of caregivers valued neuropsychology-informed care, with some describing it as transformative. Almost all practitioners (91%) reported that the project added value to their clinical care. There were no adverse effects on participants nor the flow of patients through the system.

Conclusions: Neuropsychology-informed pediatric OPMH care was feasible and well-received. Clinical effectiveness should be studied in an experimental trial.

Objective: Although elevated social anxiety in developmental prosopagnosia (DP) has been reported in anecdotal and qualitative studies, the current study sought to better quantify the prevalence, severity, and moderators of social anxiety in a large DP sample.

Method: A total of 88 DPs and 58 controls completed the validated Social Interaction Anxiety Scale and assessments of face recognition, autism traits, personality (Big Five Inventory), and coping strategies.

Results: DPs reported greater social anxiety symptoms (M = 30.25) than controls (M = 17.19), with 44% of DPs above a probable clinical cutoff compared with 14% of controls. Exploratory analyses revealed that DPs' social anxiety was more specific to items pertaining to mixing socially or interacting with unfamiliar people. Notably, several DPs reported minimal social anxiety, which was associated with being more extraverted and having fewer autism traits. A follow-up survey revealed that extraverted DPs more openly disclosed face recognition inabilities than introverted DPs, which may be a factor in their reduced social anxiety.

Conclusion: These results better quantify the potential serious psychosocial consequences of DP and highlight the importance of individual differences as well as targeted intervention.

Objective: Despite the substantial need for reliable and valid assessment of functional ability in older adults, there is currently limited research on the emergence of early functional declines during prodromal dementia stages, such as subjective cognitive decline (SCD) and mild cognitive impairment (MCI). This study uses novel performance-based assessments to characterize subtle, yet clinically meaningful, changes in functional ability.

Method: A sample of 93 older adults classified as cognitively unimpaired (CU; n = 30, Mage = 73.57 ± 6.66), SCD (n = 34, Mage = 72.56 ± 6.43), or MCI (n = 29, Mage = 78.28 ± 7.55) underwent neuropsychological testing along with an informant-rated daily functional skills measure (Assessment of Functional Capacity Interview). Participants also completed the Night Out Task (NOT), an open-ended performance-based measure of functional assessment, and the Financial Capacity Instrument-Short Form (FCI-SF) that assesses financial skills.

Results: The MCI group performed worse on the NOT and FCI-SF relative to SCD and CU. NOT and FCI scores were associated with measures of global cognitive function, executive function, processing speed, language and memory, and FCI-SF overall score was correlated with informant-rated functional ability. The NOT and FCI-SF were also predictive of informant-reported daily functioning over and above traditional cognitive data and demographics.

Conclusions: Performance-based measures of IADL may allow for earlier detection of subtle functional changes that might not be adequately captured by traditional measures. The measurement of early functional changes is an important global outcome to evaluate the efficacy of interventions in dementia research.

Objective: We investigated the feasibility of the RehaCom cognitive rehabilitation software in illiterate and low-educated individuals with mild cognitive impairment (MCI) and its clinical effectiveness in improving cognitive functions.

Methods: Twenty illiterate or low-educated individuals with MCI were randomly assigned to an intervention (IG; n = 10) and control group (CG; n = 10). The IG participated in the cognitive enhancement program for 6 weeks, twice a week and a duration of 50-60 min for each session, while the CG did not receive any kind of intervention.

Results: The two groups were demographically matched. The IG successfully completed all sessions of the cognitive enhancement program. A within-subject comparison between baseline and post-intervention assessment of cognitive functions indicated that the IG improved significantly on all administered neuropsychological tests, in contrast to the CG, whose performance remained stable between baseline and final assessment. A between-group comparison found statistically significant differences between the IG and CG groups on the Hindi Mental State Examination, Mini-Mental State Examination, and on delayed memory and recognition tasks, in favor of the IG.

Conclusions: The findings of the present study support the feasibility of applying computerized cognitive enhancement programs to illiterate and low-educated individuals. Moreover, these programs appear to contribute positively to improving the cognitive functions of this population group. In order to generalize and confirm similar findings in a broader population of illiterate and low-educated individuals, future studies should include larger samples, possibly with longer duration of treatment and control groups that will receive non-targeted interventions as placebo interventions.
