Active clinical trials for "Central Nervous System Diseases"

This cluster randomized pragmatic clinical trial will test the effectiveness and feasibility of embedding the Tele-Savvy intervention, a psychoeducational program for family and other informal caregivers of older adults living in the community with Alzheimer's disease and related dementia (ADRD), in two health care systems/clinical sites: UConn Health in Farmington, Connecticut, and Emory Healthcare in Atlanta, Georgia.

Vasoactive intestinal peptide (VIP) is a peptide of 28 amino acid residues that belongs to the glucagon/secretin superfamily of peptides. Along with other neuropeptides, such as calcitonin gene-related peptide (CGRP) and pituitary adenylate cyclase-activating polypeptide (PACAP), it is released from the trigeminal afferents and exerts a strong vasodilating activity on the cranial vasculature. Especially, it shares 70% structure with PACAP and acts on the same receptors. But, unlike it, VIP cannot induce a long-lasting vasodilation and has a modest capability to induce migraine attacks. Whether it may induce migraine-like attacks in migraine patients, as a twenty-minute infusion of PACAP, is unknown.

The specific study aims will be: To develop the novel, digital, and interactive MSR system of arm and hand with integrated digital action observation therapy (AOT) and mirror therapy (MT). To pilot usability testing for examining the feasibility of this new MSR system from the users' experiences and feedback. To examine the treatment effects of digital AOT, digital MT and a control intervention in patients with stroke by conducting a randomized controlled trial. To identify who will be the possible good responders to digital AOT and MT based on their baseline motor function and mental imagery abilities.

The aim of this study is to determine the effects of an acute session of physical exercise on cognitive functioning and humor of traumatic brain injury patients and to investigate whether different cognitive responses can be achieved with different intensities of exercise (moderate and vigorous). The investigators hypothesize that while moderate intensity physical exercise may be beneficial to cognitive functioning, vigorous intensity may be detrimental to TBI patients, as physical fatigue may impair alertness and other higher cognitive functions.

This study is conducted at the Henry Ford Health System with Lifegraph's behavioral monitoring technology, to examine the relation between migraine attacks and behavioral and environmental changes as detected from the smartphone sensors. The investigators hypothesize that Lifegraph's technology can predict the occurrence of migraine attacks with high precision.

The interventional study aims to increase the knowledge on arm and hand rehabilitation after stroke within community-based services. The primary objective of the study is to evaluate the feasibility and clinical usefulness of the arm and hand training program (focusing on functional goal- and task-oriented daily life exercises) in combination with the use of an orthotic device in terms of patient compliance and improvement of outcomes. The secondary objective is to compare the effectiveness of the program with or without the use of an orthotic device in a randomized controlled trial.

Background: People with epilepsy often have auditory processing disorders that affect their ability to hear clearly and may cause problems with understanding speech and other kinds of verbal communication. Researchers are interested in developing better ways of studying what parts of the brain are affected by hearing disorders and epilepsy, and they need better clinical tests to measure how individuals process sound. These tests will allow researchers to examine and evaluate the effects of epilepsy and related disorders on speech and communication. A procedure called a magnetoencephalography (MEG) can be used to measure the electrical currents involved in brain activity. Researchers are interested in learning whether MEG can be used to detect differences in the processing of simple sounds in patients with epilepsy, both with and without hearing impairments. Objectives: - To measure brain activity in hearing impaired persons with epilepsy and compare the results with those from people with normal hearing and epilepsy as well as people with normal hearing and no epilepsy. This research is performed in collaboration with Johns Hopkins Hospital and epilepsy patients must be candidates for surgery at Johns Hopkins. Eligibility: Individuals between 18 to 55 years of age who (1) have epilepsy and have hearing impairments, (2) have epilepsy but do not have hearing impairments, or (3) are healthy volunteers who have neither epilepsy nor hearing impairments. Participants with epilepsy must have developed seizures after 10 years of age, and must be candidates for grid implantation surgery at Johns Hopkins Hospital.. Design: This study will require one visit of approximately 4 to 6 hours. Participants will be screened with a full physical examination and medical history, along with a basic hearing test. Participants will have a magnetic resonance imaging (MRI) scan of the brain, followed by a MEG scan to record magnetic field changes produced by brain activity. During MEG recording, participants will be asked to listen to various sounds and make simple responses (pressing a button, moving your hand or speaking) in response to sounds heard through earphones. The MEG procedure should take between 1 and 2 hours. Treatment at NIH is not provided as part of this protocol.

The purpose of this study is evaluate the natural course of disease progression related to gross motor function in children with metachromatic leukodystrophy (MLD).

The aim of this study was to translate the SECONDs from French into Chinese and assess the validity and reliability of the Chinese version of the SECONDs .

The investigators hypothesize that ten sessions of repetitive transcranial magnetic stimulation yield ability to upregulate the function of primary motor cortex and prefrontal cortex that play key roles in motor and frontal memory processing.
