Active clinical trials for "Neurobehavioral Manifestations"

There is an increasing focus on the need to optimise nutrition, lifestyle and metabolism of parents before and during pregnancy and of the infant after birth, but as yet there is limited understanding of the specific influences and of the underlying mechanisms. This study is a follow up of children from the NiPPeR trial of a nutritional drink enriched with micronutrients, myo-inositol and probiotics taken preconception and during pregnancy. In this setting we will examine the influence of parental nutrition, lifestyle and metabolism before and during pregnancy on child growth, development and well-being; ascertaining growth, adiposity, metabolism, neurobehavioural and health outcomes in the children, and characterising the underlying mechanisms. The data collected will allow identification of the contributions of parental and offspring characteristics, nutritional, lifestyle and medical factors, social and economic status, ethnicity, genetics, metabolism and microbes to promoting healthy growth, body composition and wellbeing in the children.

The goal of this study is to investigate a new treatment for chronic symptoms after concussion or mild traumatic brain injury in people aged 18-65 years old. Chronic symptoms could include dizziness, headache, fatigue, brain fog, memory difficulty, sleep disruption, irritability, or anxiety that occurred or worsened after the injury. These symptoms can interfere with daily functioning, causing difficulty returning to physical activity, work, or school. Previous concussion therapies have not been personalized nor involved direct treatments to the brain itself. The treatment being tested in the present study is a noninvasive, personalized form of brain stimulation, called transcranial magnetic stimulation (TMS). The investigators intend to answer the questions: Does personalized TMS improve brain connectivity after concussion? Does personalized TMS improve avoidance behaviors and chronic concussive symptoms? Do the improvements last up to 2 months post-treatment? Are there predictors of treatment response, or who might respond the best? Participants will undergo 14 total visits to University of California Los Angeles (UCLA): One for the baseline symptom assessments and magnetic resonance imaging (MRI) Ten for TMS administration Three for post-treatment symptom assessments and MRIs Participants will have a 66% chance of being assigned to an active TMS group and 33% chance of being assigned to a sham, or inactive, TMS group. The difference is that the active TMS is more likely to cause functional changes in the brain than the inactive TMS.

A Blind-adjudication Multi-center Phase II Randomized Clinical Trial of Continuous Low-dose Intravenous Heparin Therapy in Coiled Low-grade Aneurysmal Subarachnoid Hemorrhage Patients with Significant Hemorrhage Burden. - STUDY IS TEMPORARILY SUSPENDED WITH PLAN TO RESUME SOON. NO SAFETY CONCERNS

The purpose of this protocol is to allow for the careful evaluation of healthy volunteers and individuals with risk for psychiatric disorders or neurodevelopmental disorders, such as autism spectrum disorder for specific protocols at NIH.

The Rett Syndrome Registry is a longitudinal observational study of individuals with MECP2 mutations and a diagnosis of Rett syndrome. Designed together with the IRSF Rett Syndrome Center of Excellence Network medical directors, this study collects data on the signs and symptoms of Rett syndrome as reported by the Rett syndrome experts and by the caregivers of individuals with Rett syndrome. This study will be used to develop consensus based guidelines for the care of your loved ones with Rett syndrome and to facilitate the development of better clinical trials and other aspects of the drug development path for Rett syndrome.

Parkinson's disease is the second most common neurodegenerative disease after Alzheimer's disease. It is mostly characterized by the presence of motor difficulties. However, it can also be accompanied by cognitive disorders which have an equally significant impact on the quality of life of patients and which are not relieved by any treatment. Among the functions affected by Parkinson's disease, inhibition is an essential process for adapting our behaviors in daily life. Inhibition allows us to stop an action that is no longer required or appropriate to the situation in which we find ourselves in. For example, it comes into play when we have to stop at a "stop" sign while driving. Recent studies suggest that it could be possible to improve the functioning of these processes by using non-invasive brain stimulation tools. Transcranial alternating current electrical stimulation has thus showed promising results in improving functions such as working memory. This technique is completely painless and non-invasive and consists in applying an electric current of very low intensity (barely perceptible) at the level of the scalp, using electrodes. The investigators are conducting a study to test whether transcranial alternating current electrical stimulation could improve the functioning of the inhibition process which is altered in patients. For this, the investigators will measure this process using a task performed on a computer (the Stop Signal Reaction Time Task), as well as brain activity using a method called "electroencephalography", before and after stimulation. For this study, the investigators will include 50 patients and 40 healthy participants to investigate the effect of the stimulation on inhibition.

The purpose of this study is to study the effects of attention training interventions on symptoms and brain function in major depressive disorder.

This study is designed to investigate the efficacy and safety of rivastigmine compared with placebo in patients with mild cognitive impairment (MCI).

The purpose of this study is to contribute evidence towards the potential to improve cognition in HIV+ individuals experiencing cognitive decline through personalized change in antiretroviral (ARV) medication. To that end, following a comprehensive evaluation to identify confounding clinical conditions, study participants will undergo a lumbar puncture to: (i) measure viral load (at 2 copies/ml); (ii) identify Cerebrospinal Fluid (CSF) genotype and tropism; and (iii) measure concentration of antiretroviral agents. When indicated from the CSF analysis, a personalized change in ARV will be implemented. Cognition will be measured in all at study entry and 6 months later.

This is a double-blind, randomized, sham-controlled clinical trial that aim to verify the safety and the efficacy of anodal transcranial direct current stimulation (tDCS) on cognitive and motor symptoms in Progressive Supranuclear Palsy (PSP) over the left dorsolateral prefrontal cortex (dlPFC).
