Brain Connectivity in Neurodevelopmental Disorders in Response to

Status Enrolling by invitation

Clinical Trial Summary

The purpose of the proposed research is to study the potential changes in biomarkers of patients with neurodevelopmental disorders in response to treatment in clinical trials or in private psychiatry practice utilizing non-invasive psychophysiological measurements. The investigators plan to obtain psychophysical measurements throughout several periods of treatment.

Clinical Trial Description

This study will employ a non-invasive custom-built four-point vertical displacement stimulator. This is used to deliver sinusoidal vibrations at very low amplitudes (0-400 microns) to the tips of the fingers. The forearm of the subject rests on the stimulator, the finger tips are vibrated, and the subject answers questions prompted by a computer monitor about their perception of the stimuli. Research staff may explain questions and prompts in a way that may be better understood by the subjects if the subjects experience any difficulty.

This device will be used to obtain objective psychophysical measurements as subjects undergo treatment. The investigators hope that this study will eventually assist in the long term goal of studying ways to develop diagnostic methods, based on changes in cortical information processing capabilities that occur with neurodevelopmental disorders. This would enable clinicians to more objectively determine prognosis and the best course of intervention for their patients.

This study will consent up to 60 subjects who are have initiated or changed pharmacologic treatment as either a participant in a clinical trial or as a private patient of one of the study doctors. Subjects who are a participant in another clinical trial may be one an active medication or a non-active medication(placebo). Subjects will have 7 visits in this study (w0 prior to initiating new treatment, and 4,8, 26 52,78 and 104 weeks after starting the the new treatment. The latter visits may occur either while the individual is taking the medication or after the individual has stopped treatment (in order to assess persistence of treatment-related changes). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
