NCT05650775
The goal of this translational biomarker study is to use electroencephalography (EEG) to identify brain signatures that will predict a child's response to two of the most commonly prescribed ADHD medications, methylphenidate and mixed amphetamine salts. The main questions the investigators aim to answer are: 1. Do children with ADHD who show symptom reduction with methylphenidate have different EEG profiles than children who do not respond well to methylphenidate? 2. Do children who respond better to mixed amphetamine salts than to methylphenidate have unique EEG profiles? The investigators will measure brain activity before the participating children have tried any stimulant medications, and then again after a 3-week trial of Concerta (methylphenidate). Participants who do not show significant symptom improvement on Concerta will then complete a 3-week trial of Adderall (mixed amphetamine salts), and the study will measure brain activity while those children are on the best dose of Adderall. The investigators will collect information from the child, caregivers, and teachers each week to measure ADHD symptom improvement and side effects. This study will therefore follow the typical treatment approach used in the Boston Children's Hospital Developmental Medicine Clinic, but the investigators will add measures of brain functioning before and after medication.
NCT05268887
Parkinson's disease (PD) impacts different types of neural oscillations in the brain, including beta (13-30Hz) and gamma oscillations (30-80Hz), which contributes to PD's cardinal symptoms of resting tremor, rigidity, bradykinesia (slowness of movement), and gait instability. The investigators' lab has developed a non-invasive method of increasing gamma power in the brain using Gamma Entrainment Using Sensory Stimulation (GENUS) through light, sound, and tactile stimulation devices. For this study, 40 participants with mild Parkinson's disease will be recruited, and the investigators will assess their brain waves with electroencephalogram (EEG) before, during, and after light, sound, and tactile stimulation to determine the safety, feasibility, and optimization of GENUS as a potential therapy in the PD population.
