10 Clinical Trials for Various Conditions
The purpose of this study is to determine whether repetitive transcranial magnetic stimulation (rTMS) is effective in remediating cognitive deficits while also improving functionality in Veterans with schizophrenia.
Primary objective: 1. To examine the efficacy of melatonin treatment on neurocognitive functioning in adult survivors of childhood cancer. Secondary objectives: 1. To evaluate the efficacy of melatonin treatment on delayed sleep onset latency in long-term childhood cancer survivors. 2. To investigate whether improvement in sleep onset latency due to melatonin treatment is associated with neurocognitive improvement in long-term childhood cancer survivors. This study is a randomized double-blind placebo controlled trial of time release melatonin for adult survivors of childhood cancer who demonstrate impaired neurocognitive functioning and/or difficulty falling asleep.
This research is examining how genetic and brain factors play a role in adolescents' health risk behavior as well as studying behaviors that young people engage in that may place them at risk for contracting a sexually transmitted disease like HIV/AIDS, and what kind of educational program works best to reduce these risky behaviors.
The purpose of this study is to determine whether taking the medication memantine reduces impairment of memory and attention associated with electroconvulsive therapy.
Children with neurofibromatosis are more likely to have difficulties related to their psychological and neurocognitive functioning (e.g., more likely to have depression, have social difficulties, be diagnosed with ADHD). The purpose of this randomized control study is to determine how effective and useful this study's single session intervention can be in improving psychological and neurocognitive functioning. Enrolled families will consist of one parent/guardian and child. Parents and patients will complete questionnaires and objective tests at baseline, 3 months, and 6 months. Families randomized to the intervention arm will be provided with one single session intervention at Month 1 to learn about their child's testing results and receive psychoeducation and recommendations related to psychological and neurocognitive functioning.
The purpose of this study is to collect normative test values and demographic information for normative and referential data for a rapid, portable, computerized neurocognitive testing device from healthy adults 50 and older.
Brain metastases are a source of much morbidity and mortality in adults with primary solid malignant tumors. With improvements in systemic therapy that prolong survival but have limited central nervous system penetration, patients with brain metastases are at increasing risk of developing and experiencing long-term side effects from treatment of brain metastases. The overarching goal of this study is to better understand the determinants of RT-associated changes in white and gray matter function and associated neurocognitive decline.
Inattentiveness and impulsivity in healthy adults and individuals with attention deficit hyperactivity disorder (ADHD) diminish these individuals' quality of life. Cortical hypometabolism has been hypothesized to contribute to inattentiveness in ADHD. Transcranial photobiomodulation (tPBM) is a safe and non-invasive modality for activation of the prefrontal cortex. tPBM in healthy adults has been shown to augment brain oxygenation, cognition, and mood. The cognition-enhancing effect of tPBM on sustained attention in adults with ADHD remains unstudied. The investigators will evaluate whether tPBM administration to adults with and without ADHD can improve their attention. Each participant will be screened for eighteen criteria based on the Diagnostic and Statistical Manual (DSM-IV, text revised), using the validated instrument Adult ADHD Self-Report Scale (ASRS-v1.1). Blinded participants will be randomized into (I) Active-tPBM or (II) Sham-tPBM groups. After undergoing an 8-minute administration of Sham or 1064 nm tPBM to the lateral and medial right prefrontal cortex, each participant will complete a 14-minute, computer-based Conner's continuous performance task-3 (CPT-3). The investigators will examine whether adults with and without ADHD who receive Active-tPBM improve in measures of inattention, impulsivity, sustained attention, or vigilance compared to the Sham-tPBM group. Cognitive assessments of attention like the CPT-3 may evaluate the efficacy of tPBM to increase cortical metabolism in healthy adults and individuals with conditions like ADHD. The investigators anticipate their investigation will be a starting point for more sophisticated studies that focus on the implications of tPBM on cognition.
This study seeks to characterize sleep physiology in adolescents with and without Attention deficit hyperactivity disorder (ADHD) and its relationship to differential neurocognitive and clinical outcomes within these groups.
The purpose of this research is to learn more about how children with mental health problems, including bipolar disorder (BD), attention deficit hyperactivity disorder (ADHD), and generalized anxiety disorder (GAD), differ from children without these problems. The investigators want to understand how these 4 groups of children differ in brain activity, function, and structure.
