Picture Description of the Western Aphasia Battery Picnic Scene: Reference Data for the French Canadian Population.

PURPOSE: The main aim of this study is to provide French Canadian reference data for quantitative measures extracted from connected speech samples elicited by the Western Aphasia Battery-Revised picnic scene, a discourse task frequently used in clinical assessment of acquired language disorders. METHOD: Our sample consisted of 62 healthy French Canadian adults divided in two age groups: a 50- to 69-year-old group and a 70- to 90-year-old group. RESULTS: High interrater reliability scores were obtained for most of the variables. Most connected speech variables did not demonstrate an age effect. However, the 70- to 90-year-old group produced more repetitions than the 50- to 69-year-old group and displayed reduced communication efficiency (number of information content units per minute). CONCLUSION: These findings contribute to building a reference data set to analyze descriptive discourse production in clinical settings.

The Mirror Effect Plus Protocol for acute Bell's palsy: a randomised and longitudinal study on facial rehabilitation.

BACKGROUND: Small but interesting evidences suggest that facial rehabilitation for acute Bell Palsy (BP) could improve facial outcomes in patients who benefited from optimal medication, but whose symptoms are still severe two weeks after BP's onset. AIMS: This study aimed to provide preliminary evidence of the long-term effects of a new facial retraining based on motor imagery and mirror therapy, the Mirror Effect Plus Protocol (MEPP). MATERIAL AND METHODS: Twenty BP patients received the standard medication for acute BP and were then randomly allocated to the treatment (MEPP) or control group, if their palsy was still at least moderate-to-severe at 14 days post onset. Three blind independent assessors graded the patients' evolution until 6 months after onset. RESULTS: Significant differences between the groups were not found for any measured variable; however, a trend toward better recovery was found in the treatment group for every measured variable. This trend grew bigger for patients with severe or total BP. CONCLUSIONS: This study suggests a promising effect of the MEPP on acute severe to total BP but requires further investigation with a larger number of participants. SIGNIFICANCE: Facial rehabilitation should be considered as an adjunct to medication for acute and most severe degrees of BP.

Mindfulness and psychoeducation to manage stress in amnestic mild cognitive impairment: A pilot study.

Objectives: Amnestic mild cognitive impairment (aMCI) often corresponds to the prodromal stage of Alzheimer disease (AD). The aMCI stage represents a crucial time window to apply preventive interventions in an attempt to delay cognitive decline. Stress, one of AD's modifiable risk factors frequently co-occurring with aMCI, stands out as a key intervention target. The goal of this study was to assess the impacts of two non-pharmacological interventions, mindfulness and psychoeducation, on stress at the psychological and physiological levels among aMCI older adults. Methods: Forty-eight aMCI participants were randomized between a mindfulness-based intervention (MBI) and a psychoeducation-based intervention (PBI) for eight weekly sessions. Anxiety symptoms, perceived stress levels, cortisol awakening response (CAR), and coping strategies were assessed pre- and post-intervention. Mindfulness attitudes and time dedicated to at-home meditative practices were evaluated in the MBI group. Results: The main results revealed a slight reduction of the CAR among MBI participants who practiced meditation at home the most and a decrease in perceived stress levels in the PBI group. Both interventions enhanced problem-focused coping strategies. Conclusion: In sum, this pilot study supports the potential of MBI and PBI to reduce stress at the physiological and psychological level, respectively, and increase coping strategies in older adults at risk for AD.

The Dépistage Cognitif de Québec: A New Clinician's Tool for Early Recognition of Atypical Dementia.

INTRODUCTION: Early recognition of atypical dementia remains challenging partly because of lack of cognitive screening instruments precisely tailored for this purpose. METHODS: We assessed the validity and reliability of the Dépistage Cognitif de Québec (DCQ; www.dcqtest.org), a newly developed cognitive screening test, to detect atypical dementia using a multicenter cohort of 628 participants. Sensitivity and specificity were compared to the Montreal Cognitive Assessment (MoCA). A predictive diagnostic algorithm for atypical dementia was determined using classification tree analysis. RESULTS: The DCQ showed excellent psychometric properties. It was significantly more accurate than the MoCA to detect atypical dementia. All correlations between DCQ indexes and standard neuropsychological measures were significant. A statistical model distinguished typical from atypical dementia with a predictive power of 79%. DISCUSSION: The DCQ is a better tool to detect atypical dementia than standard cognitive screening tests. Expanding the clinician's tool kit with the DCQ could reduce missed/delayed identification of atypical dementia and accelerate therapeutic intervention.
