研究概览

简要总结

Background:

Puberty is a normal part of life. Many big changes occur in all parts of the body as a child matures into an adult. Researchers in this study want to find out more about how the brain changes during puberty.

Objective:

To study changes that occur in the brain before, during, and after puberty.

Eligibility:

Healthy children aged 9 to 14 years.

Design:

Participants will have 2 clinic visits. Each visit will last up to 4 hours.

In the first visit, participants will be screened:

They will have a physical exam with blood tests.

They will complete a mental health questionnaire on a computer.

They will undergo a mock magnetic resonance imaging (MRI) scan. Participants will be made comfortable as they lie on the table and slide into the big tube. They will learn what it feels and sounds like to lie still inside a real MRI.

At the second visit, participants will have more tests:

They will have a physical exam with blood tests. This time the doctor will check for their stage of puberty. The doctor will look at and touch their genitals and breasts.

They will have a real MRI exam.

An x-ray will be taken of their hand and wrist. This will show how their bones are maturing.

They will have a DEXA scan. They will lie on a table while a machine uses x-rays to measure the makeup of their bodies, including bone, muscle, and fat.

They will have a 3D body scan. They will wear tight clothes and a shower cap. They will stand on a platform while sensors take pictures of their body.

详细描述

Study Description:

We aim to establish the feasibility of recruitment of children aged 9 to 14 years old to obtain high-quality neuroimaging of white matter determinants employing the Bayesian Monte Carlo analysis of multicomponent driven equilibrium single-component observation of T1 and T2 (BMC-mcDESPOT) and constrained neurite orientation dispersion and density imaging (C-NODDI) Magnetic Resonance Imaging (MRI) techniques with a cross-sectional observational pilot study. We additionally aim to establish the feasibility of multidimensional assessment of pubertal status and body composition as they relate to brain white matter. Data from this pilot study would inform the design of our intended future longitudinal investigations gathering reference data descriptive of normative cerebral microstructural changes in a healthy young population.

Objectives:

The primary objective is to demonstrate feasibility of obtaining highquality BMC-mcDESPOT and C-NODDI MRI data from participants between 9 and 14 years old.

The main exploratory objective is to demonstrate the feasibility of completing multidimensional assessments of pubertal status and body composition of participants between 9 and 14 years old to be related to the neuroimaging.

入选标准

  • INCLUSION CRITERIA:
  • In order to be eligible to participate in this study, an individual must meet all of the following criteria:
  • Stated willingness to comply with all study procedures and availability for the duration of the study.
  • Male or female, 9 to 14 years of age.
  • In good general health
  • Ability of parent/guardian to understand and the willingness to sign a written informed consent document.
  • Ability of participant to participate in the assent process and willingness to sign a written informed assent document.

排除标准

  • An individual who meets any of the following criteria will be excluded from participation in this study:
  • Any known brain abnormalities (e.g. tumor, periventricular leukomalacia, microcephaly) or history of medical conditions known to affect cerebral micro or macro-structural integrity (e.g., epilepsy, history of stroke, head injury with a loss of consciousness of one hour or more).
  • History neurodevelopmental delay or disorder, learning disability, intellectual disability (formerly referred to as mental retardation), autism spectrum disorders, and attention deficit/hyperactivity disorder (ADHD)), as evaluated history, physical and by the SDQ, and if indicated, the KSADS
  • History of psychiatric disorder as evaluated by history and the SDQ, and if indicated, the KSADS.
  • History of prematurity (< 32 weeks gestational age).
  • History of endocrine abnormalities, including diagnosed disorders of thyroid, growth, and precocious or delayed puberty
  • History of major medical conditions or chronic medical conditions. Examples include neurological disorders, medical or genetic conditions with associated neurological manifestations, malnutrition, conditions raising risk of micronutrient or macronutrient deficiencies (e.g. inflammatory bowel disease), untreated chronic anemia, cardiovascular disease, significant lung disease (e.g. bronchiectasis), significant liver disease, significant kidney disease, significant autoimmune condition, and chronic infections (e.g. HIV, hepatitis B).
  • Pregnancy.
  • Not eligible to have an MRI as per the MRI eligibility form and the safety standards of the NIA 3T MRI center.
  • Presence of hardware (e.g. orthodontic braces) that may interfere with MRI data quality.
  • Any other condition which in the investigator s opinion may adversely affect the subject s ability to complete the study or its measures or which may pose significant risk to the subject.
