Mental health curricula in predoctoral dental school programs: A content analysis.

Background: Given the prevalence of mental health concerns, dentists have an opportunity to provide mental health screenings to enhance overall patient care. The purpose of this study is to summarize and discuss the characteristics of mental health curricula related to patient care in accredited dental schools.

Methods: We identified accredited predoctoral dental programs incorporating mental health training related to patient care into their curriculum.

Mental health screenings in dental settings: Feasibility and outcomes from a study by The National Dental Practice-Based Research Network.

Background: With the rising importance of mental health screenings in nontraditional settings, dental offices offer an important opportunity to provide these services. This feasibility study examined mental health screenings and referral to treatment procedures in dental practices.

Methods: A total of 17 dentists, dental hygienists, and dental office staff members (dental office personnel [DOP]) from 5 dental practices enrolled 36 patients in the study.

Elevated Smooth Pursuit Gain in Collegiate Athletes with Sport-related Concussion Immediately Following Injury.

Purpose: Although there is evidence that sport-related concussion (SRC) affects oculomotor function and perceptual ability, experiments are often poorly controlled and are not replicable. This study aims to test the hypothesis that there are decreased values when assessing oculomotor impairment indicating poorer performance in SRC patients.

Methods: Fifteen DI athletes presenting with SRC (7 females, 8 males) and 15 student volunteers (CON) (12 females, 3 males) completed a dynamic visual acuity (DVA) task that involved answering the direction of a moving stimulus (Landolt C) while wearing a head-mounted binocular eye tracker.

Perceptions of mental health screening and referral to treatment in National Dental-Practice Based Research Network practices: A qualitative study.

Objectives: Dental practices can have additional positive impacts on public health by implementing mental health screening and referral to treatment in dental care workflows. In this study, we examined how dental practices identify and address adult patient mental health concerns, attitudes about implementing mental health screening and referral, and potential barriers and facilitators to treatment.

Methods: We conducted semi-structured focus groups with 17 dentists, 10 dental hygienists, and 5 dental assistants/office staff in the South-Central region of the National Dental Practice-Based Research Network.

Pattern glare sensitivity distinguishes subclinical autism and schizotypy.

Introduction: Schizophrenia and autism spectrum disorder are distinct neurodevelopmental disorders sharing clinically relevant behaviours. However, early sensory responses show divergent responses. Individuals with schizophrenia typically exhibit cortical whereas individuals with autism show cortical .

Mental health screening and referral to treatment in dental practices: A scoping review.

Objective: The purpose of this study was to conduct a scoping review to examine and summarize the characteristics of research related to mental health (MH) screenings and/or referrals to treatment in dental practices.

Methods: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for Scoping Reviews and searched multiple databases for terms connected with dental care, MH concerns, screening, and referral. Included articles: (1) described care provided in a dental practice, (2) described a situation where the patient is experiencing the potential MH problem, (3) did not involve dental anxiety exclusively, and (4) involved some form of MH screening and/or referral to treatment.

Augmenting Virtual Reality Exposure Therapy for Social and Intergroup Anxiety With Transcranial Direct Current Stimulation.

Objectives: Exposure therapy is a cornerstone of social anxiety treatment, yet not all patients respond. Symptoms in certain social situations, including intergroup (ie, out-group) contexts, may be particularly resistant to treatment. Exposure therapy outcomes may be improved by stimulating neural areas associated with safety learning, such as the medial prefrontal cortex (mPFC).

Capturing postpandemic changes in research participants.

The impact of the COVID-19 pandemic on physical and mental health hardly need be reiterated. Yet, there are likely other indirect aftereffects of COVID-19 infection in addition to the direct effects. This article aims to initiate a conversation regarding difficult-to-capture outcomes of the pandemic that are relevant to researchers who test human participants.

The Rehabilitation Potential of Neurostimulation for Mild Traumatic Brain Injury in Animal and Human Studies.

Neurostimulation carries high therapeutic potential, accompanied by an excellent safety profile. In this review, we argue that an arena in which these tools could provide breakthrough benefits is traumatic brain injury (TBI). TBI is a major health problem worldwide, with the majority of cases identified as mild TBI (mTBI).

Working memory and sensory memory in subclinical high schizotypy: An avenue for understanding schizophrenia?

The search for robust, reliable biomarkers of schizophrenia remains a high priority in psychiatry. Biomarkers are valuable because they can reveal the underlying mechanisms of symptoms and monitor treatment progress and may predict future risk of developing schizophrenia. Despite the existence of various promising biomarkers that relate to symptoms across the schizophrenia spectrum, and despite published recommendations encouraging multivariate metrics, they are rarely investigated simultaneously within the same individuals.

Gender Differences in Adolescents' Affective Symptoms and Behavioral Disorders After Mild Traumatic Brain Injury.

Objective: Mild traumatic brain injuries (mTBI) are considered self-limiting and full recovery is expected. Recent studies identify deficits persisting years after mTBI. Large-scale prospective data permit testing the hypothesis that mTBI increases incidence of affective and behavioral symptoms after new, past , or new and past mTBI.

People with high schizotypy experience more illusions in the Pattern Glare Test: Consistent with the hyperexcitability hypothesis.

Individuals diagnosed with schizophrenia spectrum disorders (SSD) exhibit a constellation of sensory and perceptual impairments, including hyporeactivity to external input. However, individuals with SSD also report subjective experiences of sensory flooding, suggesting sensory hyperexcitability. To identify the extent to which behavioural indices of hyperexcitability are related to non-psychotic symptoms of schizophrenia, we tested a non-clinical population measured for schizophrenia-like traits (schizotypy), and a behavioural measure of sensory hyperexcitability, specifically the number of illusions seen in the Pattern Glare Test.

Can brain stimulation enhance cognition in clinical populations? A critical review.

Many psychiatric and neurological conditions are associated with cognitive impairment for which there are very limited treatment options. Brain stimulation methodologies show promise as novel therapeutics and have cognitive effects. Electroconvulsive therapy (ECT), known more for its related transient adverse cognitive effects, can produce significant cognitive improvement in the weeks following acute treatment.

Caught in the ACTS: Defining Abstract Cognitive Task Sequences as an Independent Process.

Cognitive neuroscience currently conflates the study of serial responses (e.g., delay match to sample/nonsample, n-back) with the study of sequential operations.

Individual predictors and electrophysiological signatures of working memory enhancement in aging.

A primary goal of translational neuroscience is to identify the neural mechanisms of age-related cognitive decline and develop protocols to maximally improve cognition. Here, we demonstrate how interventions that apply noninvasive neurostimulation to older adults improve working memory (WM). We found that one session of sham-controlled transcranial direct current stimulation (tDCS) selectively improved WM in older adults with more education, extending earlier work and underscoring the importance of identifying individual predictors of tDCS responsivity.

Addressing the Gender Gap in Research: Insights from a Women in Neuroscience Conference.

There has been growing interest in quantifying the proportion of women participating in scientific conferences, publications, and committees. Numbers reveal persistent disparities, but offer few cures to the root causes of the gender gaps in research. Toward remediation, we outline five lessons learned through organizing two conferences for Women in Neuroscience (WiN).

Impaired visual working memory and reduced connectivity in undergraduates with a history of mild traumatic brain injury.

Mild traumatic brain injury (mTBI), or concussion, accounts for 85% of all TBIs. Yet survivors anticipate full cognitive recovery within several months of injury, if not sooner, dependent upon the specific outcome/measure. Recovery is variable and deficits in executive function, e.

Predicting Working Memory Training Benefits From Transcranial Direct Current Stimulation Using Resting-State fMRI.

The effects of transcranial direct current stimulation (tDCS) on working memory (WM) performance are promising but variable and contested. In particular, designs involving one session of tDCS are prone to variable outcomes with notable effects of individual differences. Some participants benefit, whereas others are impaired by the same tDCS protocol.

No tDCS augmented working memory training benefit in undergraduates rewarded with course credit.

Background: The goal of working memory (WM) training is to expand capacity of this executive function. Transcranial direct current stimulation (tDCS) paired with WM training is more consistent than either alone. We have reported that tDCS targeting frontal and/or parietal regions enhanced theta phase locking, reduced alpha power, and strengthened theta-gamma phase amplitude coupling.

Frontoparietal theta-gamma interactions track working memory enhancement with training and tDCS.

Despite considerable interest in enhancing, preserving, and rehabilitating working memory (WM), efforts to elicit sustained behavioral improvements have been met with limited success. Here, we paired WM training with transcranial direct current stimulation (tDCS) to the frontoparietal network over four days. Active tDCS enhanced WM performance by modulating interactions between frontoparietal theta oscillations and gamma activity, as measured by pre- and post-training high-density electroencephalography (EEG).

Smooth Pursuit and Saccades after Sport-Related Concussion.

Smooth pursuit eye movements (SPEMs) and saccadic eye movements are both commonly impaired following sport-related concussion (SRC). Typical oculomotor assessments measure individual eye movements in a series of restrictive tests designed to isolate features such as response times. These measures lack ecological validity for athletes because athletes are adept at simple tasks designed for the general population.

Replacing tDCS with theta tACS provides selective, but not general WM benefits.

Working memory (WM) can be improved after repeated training sessions paired with noninvasive neurostimulation techniques. Previously, we reported that WM training paired with tDCS succeeded behaviorally by enhancing anterior-posterior theta phase coherence and reducing alpha power. Here, in two experiments we tested several theta and alpha frequencies and two transcranial alternating current stimulation (tACS) montages in an effort to shortcut WM training while preserving behavioral gains.

Visual working memory deficits in undergraduates with a history of mild traumatic brain injury.

We investigated whether a history of mild traumatic brain injury (mTBI), or concussion, has any effect on visual working memory (WM) performance. In most cases, cognitive performance is thought to return to premorbid levels soon after injury, without further medical intervention. We tested this assumption in undergraduates, among whom a history of mTBI is prevalent.

Visual statistical learning deficits in memory-impaired individuals.

Visual statistical learning (VSL) refers to the learning of environmental regularities. Classically considered an implicit process, one patient with isolated hippocampal damage is severely impaired at VSL tasks, suggesting involvement of explicit memory. Here, we asked whether memory impairment (MI) alone, absent of clear hippocampal pathology, predicted deficits across different VSL tasks.
