Attention and Memory Research Study

This research study seeks to understand if two commonly prescribed medications affect attention and anxiety while performing computer-based tasks. The study involves one assessment visit and two outpatient visits.

The study is enrolling healthy participants ages 18-50. You may be eligible if you no current psychiatric disorder and are free of certain medical conditions.

You may not be eligible is you are pregnant or nursing, have heart disease, neurological disease, certain mental health disorders, or any health problems that would interfere with the study or make it unsafe for you.

Research Participation Includes: Taking one dose of a medication: either Ritalin, Inderal, or placebo (an inactive pill), and performing computer tasks under stressful conditions. Participation may include a brain scan (functional Magnetic Resonance Imaging (fMRI).

The study is conducted at the NIH Clinical Center, America’s research hospital, located on the Metro red line (Medical Center stop) in Bethesda, MD. Parking is provided at no cost. There is no charge for study related procedures and compensation is provided.

First Steps to Participate in Research: Learn study details, ask about your eligibility, and consent to participate. Refer to study no. 14-M-0114. Se habla español.

To find out if you qualify, email NIMH or call 1-301-451-5087 [TTY: 1-866-411-1010].

Brain and Body Responses to Stress Study

The purpose of this research study is to better understand how the brain and body work when healthy volunteers feel anxious.

Research Participation Includes: 1-4 outpatient visits, computer tasks, and exposure to unpleasant stimuli. Researchers will assess changes in heart rate, muscle activity, sweat responses, and respiration.

Who Can Participate: Healthy volunteers between the ages of 18-50, who have no current psychiatric disorder and are free of certain medical conditions.

You may not be eligible if you are pregnant, have current drug or alcohol abuse, heart disease, neurological disease, or any health problems that would interfere with the study or make it unsafe for you.  

The study is conducted at the NIH Clinical Center in Bethesda, Maryland. The testing sessions may take up to 3 hours. There is no cost to participate and compensation is provided.

First Steps to Participate in Research: Learn study details, ask about your eligibility, and consent to participate.

To find out if you qualify, email NIMH or call 1-301-451-5087 [TTY: 1-866-411-1010].

Who Can Participate: Healthy volunteers between the ages of 18-50, who have no current psychiatric disorder and are free of certain medical conditions.

You may not be eligible is you are pregnant, have pacemaker, current alcohol or substance abuse problems, heart disease, neurological disease, or any health problems that would interfere with the study or make it unsafe for you.  

The study is conducted at the NIH Clinical Center in Bethesda, Maryland. The testing sessions will take up to 2.5 hours. There is no cost to participate and compensation is provided.

First Steps to Participate in Research: Learn study details, ask about your eligibility, and consent to participate.

Brain Imaging and A Study Drugs Effects on Brain Receptors

This research study will evaluate the effects of the experimental medication ketamine on brain receptors in healthy and depressed adults. The study is enrolling healthy participants ages 18-65.  You may be eligible if you free of psychiatric disorders and certain medical conditions.

Research includes 1 to 6 weeks of outpatient procedures: a screening visit, computer tasks, rating scales, neurological testing, two intravenous infusions, a blood draw, brain scans (MEG & fMRI); and may include optional 2-4 overnight stays for a sleep study.

First Steps to Participate include, calling NIMH, learning study details, asking about your eligibility, and consenting to participate.

To find out if you qualify, email NIMH or call 1-877-646-3644 (1-877-MIND-NIH) [TTY: 1-866-411-1010].

Brain Imaging of Childhood Onset Psychiatric Disorders, Endocrine Disorders and Healthy Volunteers

The purpose of this study is to understand brain development during childhood and brain changes with aging. We will look at brain changes and development in healthy adults and children. We will also look at brain changes and development in people with different developmental disorders, including sex chromosome variations.

Previous studies have shown that parts of the brain develop at different times. They have also shown that brain development can be different in people with various diseases. However, we do not fully understand normal brain development and aging. We do not know how it differs in people with certain illnesses that affect thinking and behavior. We are just starting to understand how genes can affect brain development. This study examines the relationship between genes, brain development, and behavior throughout life.  Participants have a research testing visit at the start of the study, and again every 2 years. We will use tests including brain imaging with magnetic resonance imaging (MRI). We will also use physical and psychological examination and evaluation, and genetic testing. We may also ask you to have a skin biopsy, which is described in a separate consent form. We hope that a better understanding of brain development may lead to improved prevention and treatment of mental and behavioral disorders in the future.

This study includes people in good physical health, who are over 3 years old. People in this study may be without any known psychiatric/medical conditions, or may have known conditions such as Sex Chromosome Variation, Autism Spectrum Disorder, Obsessive Compulsive Disorder, and ADHD.

In this part of the study we are currently enrolling healthy volunteers 5-25 years old without current or past psychiatric or neurological diagnoses.

Healthy Volunteers will have an initial visit lasting about 6 hours and will be invited to return every two years. Procedures include a physical examination, a blood draw, an MRI scan of the brain, and cognitive tests of thinking, memory, and attention.  We may also ask you to have a skin biopsy.

The study is conducted at the NIH Clinical Center in Bethesda, Maryland (just outside Washington, D.C. There is no cost to participate in this outpatient visit and compensation is provided. Children must have parental permission to participate.
