PD patients were slower to complete the OTDL-R, but only less accurate on the telephone use subtest. Poor performance on the telephone use subtest may be related to motor severity, while poor performance on the financial management subtest was related to attention and working memory. Overall, the findings warrant future investigation to determine the validity and reliability of the OTDL-R in PD.

Objective: Many patients require repeat neuropsychological evaluations to determine change over time. Repeat evaluations lead to practice effects, which can impact the validity of the assessment. The current study assessed, in older adults, the validity of an alternative set of verbal memory stories created by Newcomer and colleagues (1994).Method: A total 154 of nondemented adults, ages 60 to 92, completed the WMS-III Logical Memory (LM) stories and two Newcomer stories (Carson-Jones) as part of a larger battery of neurocognitive tests. The Carson-Jones stories were scored for: 1) verbatim (traditional) and 2) thematic (developed for this study) accuracy. Story memory variables were compared to each other and additional neurocognitive measures using bivariate correlations. A subset of participants (n=133) completed magnetic resonance imaging (MRI) and various structural regions (e.g., thickness and volume of medial temporal lobe structures) were used to assess external validity of Carson-Jones stories with hierarchical multiple regression analyses.Results: There was a strong positive correlation between WMS-III LM and Carson-Jones stories for both verbatim and thematic scoring. Both scoring types showed convergent validity with other verbal memory measures (e.g., WMS-III LM and HVLT-R Delay/Learning) and divergent validity with Stroop Word Reading and JOLO. Regarding neuroimaging correlates, Carson-Jones verbatim scoring was significantly associated with left subiculum and left whole hippocampal volume whereas thematic scoring was significantly associated only with left subiculum.Conclusions: Newcomer stories appear to be a valid alternative to WMS-III LM stories in terms of assessing verbal memory in healthy older adults.

Neuroanatomically, it remains unclear whether diminished startle modulation in essential tremor is secondary to aberrant cerebellar input to the amygdala, which is involved in priming the startle response in emotional contexts, or due to more direct disruption between the cerebellum and brainstem startle circuitry. If the former is correct, these findings may be the first to reveal dysregulation of emotional networks in essential tremor.

Background: Music-based interventions may help to alleviate neuropsychiatric symptoms of dementia and promote prosocial interactions between individuals living with dementia and their caregivers. However, current literature does not combine these evidence bases toward explanation of how music-based interventions may alleviate symptoms and promote prosocial interactions. Objective: We conducted a scoping review to address the following question: what do the evidence bases suggest toward how music therapy or music-based therapeutic interventions might promote prosocial interactions between individuals living with dementia and their caregivers? Methods: In this review we focused on: 1) quantitative and qualitative evidence of music-based therapies promoting prosocial behaviors in individuals living with dementia, and 2) potential neurobehavioral mechanisms associated with the processes involved with how music may promote prosocial interactions. Databases included PubMed, EBSCOhost’s CINAHL and PsycINFO, Cochrane Library (sub-search conducted using ALOIS, the Specialized Register of the Cochrane Dementia and Cognitive Improvement Group), Web of Science, clinicaltrials.gov, ProQuest’s Biological Science Collection, the Journal of Music Therapy, Nordic Journal of Music Therapy, and Google Scholar. Results: Sixteen original research studies were included for evidence synthesis. This scoping review reveals the need to define and clarify mechanisms of prosocial interactions between individuals living with dementia and their caregivers considering biological and social factors. These mechanisms may include dynamic interactions between preserved brain regions associated with music-evoked autobiographical memory recall and shifts from negative to positive mood states. Conclusion: Defining and clarifying how and to what extent music may promote prosocial behaviors using well-designed and well-controlled mixed-methods studies may positively influence the design of interventions to promote prosocial interactions with caregivers.

This study aimed to synthesize existing research on the effects of sleep disturbances on trauma‐focused psychotherapy outcomes in adults with posttraumatic stress disorder (PTSD). A systematic review using PubMed, PsycINFO, Embase, Web of Science, and PTSDpubs was performed up to April 2021. Two independent reviewers screened articles for inclusion, performed data extraction, and assessed risk of bias and certainty of the evidence. Narrative synthesis was conducted based on the type of sleep disorder symptom assessed. Sixteen primary studies were included in this review, the majority of which had a high overall risk of bias. Results suggested that sleep disorder symptoms were associated with higher overall PTSD severity across treatment; however, they did not interfere with treatment effectiveness, with the exception of sleep‐disordered breathing. Improvements in insomnia, sleep duration, and sleep quality during treatment were associated with greater treatment gains. Certainty of the evidence ranged from low to very low. These results suggest that it may not be necessary to address sleep disorder symptoms prior to initiating trauma‐focused psychotherapy. Instead, concurrent treatment of sleep‐ and trauma‐related symptoms may be most beneficial. Continued research is needed to clarify the mechanistic relationship between sleep and treatment outcomes and to guide clinical decision‐making.

Evidence for clinically meaningful benefits of transcutaneous vagus nerve stimulation (VNS) has been rapidly accumulating over the past 15  years. This relatively novel non-invasive brain stimulation technique has been applied to a wide range of neuropsychiatric disorders including schizophrenia, obsessive compulsive disorder, panic disorder, post-traumatic stress disorder, bipolar disorder, and Alzheimer’s disease. More recently, non-invasive forms of VNS have allowed for investigations within healthy aging populations. These results offer insight into protocol considerations specific to older adults and how to translate those results into effective clinical trials and, ultimately, effective clinical care. In this review, we characterize the possible mechanisms by which non-invasive VNS may promote healthy aging (e.g., neurotransmitter effects, inflammation regulation, functional connectivity changes), special considerations for applying non-invasive VNS in an older adult population (e.g., vagus nerve changes with age), and how non-invasive VNS may be used in conjunction with existing behavioral interventions (e.g., cognitive behavioral therapy, cognitive training) to promote healthy emotional and cognitive aging.
