Anxiety and emotion in parent-child dyads: A multimodal study | Campbell | $92,932

Anxiety and emotion in parent-child dyads: A multimodal study 2022 Award: $92,932 Anxiety is on the rise, is associated with altered emotional processing, and can emerge in preschool, a time when children rely on parents or caregivers to process emotional and handle worry. Developing successful treatments for childhood anxiety will depend on understanding the mechanisms that underlie it and parent-child dyads. This project is an important first step to better understand and treat anxiety disorders, by measuring brain and behavioral aspects of anxiety and emotion in both parents and children. Need/Problem: Anxiety disorders (AD) can emerge in early childhood and predict later symptoms and psychopathology. Emotional processing is an important core aspect of ADs – an underlying fear, worry, or distress. In preschool children, some worry is typical as they develop brain networks to process emotional information. This development [...]

Hormone Flux and the Emergence of Irritability During Pregnancy: Investigating the Trajectory and Neurobiological Correlates of an Underrecognized Mood State | Swales | $40,000

Hormone Flux and the Emergence of Irritability During Pregnancy: Investigating the Trajectory and Neurobiological Correlates of an Underrecognized Mood State2022 Award: $40,000Irritability is common in perinatal depression, however we do not know when irritability emerges during pregnancy and the neurobiological pathways underlying symptom progression are poorly understood. In this study we will investigate how hormone changes across pregnancy relate to the onset of irritability in women at risk for perinatal depression. We will also evaluate how hormone changes relate to neural and behavioral responses to threat and frustration, key components of irritability. Investigating the emergence and neurobiological correlates of irritability in perinatal depression is a critical first step to shed led light on this often underrecognized mood state and identify potential targets for prevention and intervention efforts that support the wellbeing of women and children.Need/Problem: Irritability is common in reproductive [...]

A novel glutamatergic mechanism for the treatment of cocaine and opioid use disorders, and co-occurring anxiety | Faccidomo | $39,565

A novel glutamatergic mechanism for the treatment of cocaine and opioid use disorders, and co-occurring anxiety 2022 Award: $39,565 Substance Use has steadily risen over the past decade and COVID-19 has exacerbated these trends. More than 50% of people diagnosed with Substance Use Disorders, are also diagnosed with co-occurring psychiatric disorders. There is a need for targeted treatments to simultaneously address these co-occurring mental health conditions. This project will systematically investigate whether a novel brain protein called TARP γ-8 could be a novel target for therapeutic interventions for substance use and anxiety. Need/Problem: Despite tremendous need, effective pharmacotherapies for the treatment of Substance Use Disorders and co-occurring psychiatric conditions are lacking. Repeated drug use dysregulates key neurotransmitter systems in the brain and leads to enduring changes in strength and function of brain pathways that regulate reward and pleasure. It [...]

Network Neuroscience of a Novel Brief Intervention for Stress and Depression Symptoms in College Students | Zhang & Schwippel | $41,080

Network Neuroscience of a Novel Brief Intervention for Stress and Depression Symptoms in College Students 2022 Award: $41,080 College students constantly experience stress, which may lead to various mental health problems. Psychosocial interventions are effective treatments, while the neural mechanisms underlying their therapeutic benefits remain unclear. In this study, we will record the brain activities of the client and the therapist simultaneously during the intervention. We will examine how synchronized brain activities between the client and the therapist may help explain the therapeutic benefits of psychosocial interventions. Need/Problem: The vast majority of college students experience a high level of stress arising from academic pressure, monetary concerns, and newly gained responsibilities as young adults. Stress-related symptoms include anxiety, sleeping problems, difficulties concentrating, and a low mood. Those symptoms might persist and develop into mental disorders like depression, thus reducing the [...]

Biomarkers of Systemic Inflammation in Alcohol Use Disorder | Morrow | $98,500

Biomarkers of Systemic Inflammation in Alcohol Use Disorder2022 Award: $98,500Studies of post-mortem brains of people who suffered from Alcohol Use Disorders show abnormal activation of inflammatory immune signals that are proposed to underlie addiction to alcohol. We propose to determine if serum levels of inflammatory markers are biomarkers of excessive alcohol drinking. Such a biomarker could provide a useful diagnostic tool and indicate if patients might respond to novel treatments that inhibit the same inflammatory pathways. We will test this idea in men and women who meet criteria for AUD in hopes of discovering a biomarker of AUD drinking severity and to facilitate study of new ways to treat alcohol use disorders.Need/Problem: The burden of alcohol use disorders (AUDs) in our society is greater than any other addictive drug, but, there is no reliable diagnostic biomarker of heavy drinking or [...]

Circuit-level investigation of global hypoconnectivity in the sensory neocortex of a mouse model for autism | Kato | $40,092

Circuit-level investigation of global hypoconnectivity in the sensory neocortex of a mouse model for autism 2022 Award: $40,092 In addition to the well-known social communication difficulties, autistic patients frequently suffer from sensory processing problems, such as sensory overload. In this project, we will investigate neural circuit alterations that affect sensory responses, using a preclinical mouse model for autism. Findings in the simple mouse brain should provide a first step toward understanding circuit mechanisms underlying broad sensory symptoms in autistic patients. Need/Problem: Atypical behavioral responses to sensory inputs, such as sensory overload and hypersensitivity, are observed in around 90% of autism spectrum disorder (ASD) patients, and developing treatments for this is critically needed to reduce the burden on patients and their families. Grant Summary: To identify the circuit alterations causing sensory processing problems in ASD, we will focus on a preclinical [...]

Co-occurrence of Disorders of Gut-Brain Interaction and Feeding and Eating Disorders in Adolescence: Prevalence, Complications, and Clinical Management | Matherne | $40,396

Co-occurrence of Disorders of Gut-Brain Interaction and Feeding and Eating Disorders in Adolescence: Prevalence, Complications, and Clinical Management 2021 Award: $40,396 A body of research is emerging that links Feeding and Eating Disorders (FEDs) to adults with Disorders of Gut-Brain Interaction (DGBI). Surprisingly, very little research has been conducted on FEDs among adolescents with DGBI. In this project, we will estimate the prevalence and identify psychiatric comorbidities and health-related symptoms of FEDs in a clinical sample of adolescents with DGBI. Data derived from the study will inform novel treatments for youth with co-occurring DGBI/FEDs that are expected to be mutually beneficial to improving patient outcomes across both fields. Need/Problem: Disorders of Gut-Brain Interaction (DGBI) involve impairing gastrointestinal symptoms occurring due to miscommunication between the gut and the brain. DGBI affect 1 in 4 youth in the community and > [...]

Biobehavioral Markers of Suicide Risk in Female Adolescents on the Autism Spectrum | Maddox | $39,992

Biobehavioral Markers of Suicide Risk in Female Adolescents on the Autism Spectrum 2021 Award: $39,992 Suicide is a leading cause of premature death for individuals on the autism spectrum. Females on the spectrum are at a particularly elevated risk of experiencing suicidal thoughts and behavior. However, very few studies have examined risk factors for suicidal thoughts and behaviors in females on the spectrum. Our project is the first prospective study of potential biological vulnerabilities for suicidal thoughts and behaviors in females on the spectrum. Study findings will set the stage for a program of research focused on identifying females on the spectrum at risk for suicide and developing tailored suicide prevention programs to improve outcomes across the lifespan. Need/Problem: Suicide is a leading cause of premature death for autistic* individuals (*note that we use identity-first language to respect the [...]
