Currently, children who are younger than 7 years of age and appear to meet criteria for an attention-deficit/hyperactivity disorder (ADHD) diagnosis may remit by the time they are 8 years old. This study looks to identify who will continue to have ADHD and who will not by using electroencephalogram. Participation in the study includes an initial three-hour study. Participants will be compensated for their time, and transportation is provided.
Eligibility: Children between the ages of 3 and 7 with or without ADHD may be eligible for this study.

The purpose of this study is to analyze genes in patients with blood disorders in order to gain a better understanding of their genetic basis. Participants will be asked to provide a blood sample that will be used to analyze their DNA for genes related to the blood disorder.
Eligibility: Patients with a blood disorder amenable to DNA sequence analysis for at least one candidate gene or genetic polymorphism who are seen at the Hematology Clinic are eligible.

The goal of this project is to examine when young infants begin to remember social events and how long the memory lasts. Mothers are asked to interact with their babies in both play and quiet situations, and information will be gathered about the baby and the family. The study requires two visits to Children's, each lasting about two hours. Participants are compensated for their involvement in the study, and free parking is available.
Eligibility: Infants between 3 to 12 months of age may be eligible.
