Once enrolled in the study, subjects will receive evaluations and testing to determine if they meet the necessary criteria for admission into study treatment. Subjects will not be responsible for the costs of any evaluations or tests conducted as part of this study.

First, subjects will receive a psychiatric and medical evaluation by the study psychiatrist to see if she/he has any psychiatric or medical illnesses that would interfere with their ability to participate in this study. These evaluations may take up to an hour to complete. In addition, subjects will be asked to participate in a psychiatric interview designed to determine the child’s diagnosis and current problem areas. The subject’s parent will also be asked to fill out psychiatric questionnaires. The interview and questionnaires may take up to 4 hours to complete.

Second, urine and blood samples will be needed for routine tests two times during this study (before any study related tests are done, and at the end of the study). Two teaspoons of blood will be drawn each time. The urine sample will be analyzed in order to assess kidney function and to screen for the presence of drugs (such as cocaine, marijuana, heroin, etc.). A positive drug screen would result in the inability of the child to participate in this study. Drug screen results will be kept confidential. In addition, an electrocardiogram will be performed to determine heartbeat.

Lastly, a pregnancy test will be conducted on the urine sample if the child is female and has reached puberty. The child should not be in this study if she is pregnant or a nursing mother. A positive urine pregnancy test would cause the child to be removed from the study. If the child is sexually active, she must be using an effective method of birth control during her participation in this study. Acceptable methods of birth control are oral contraceptive medications (the administration of which must be parentally supervised), IUD, depot medication and tubal ligation.

Subjects will be assigned by chance to receive either the active medication (Galantamine) or placebo (sugar pill) for 12 weeks, much like the flip of a coin. Neither the parent/child nor the investigator will know which of the two treatments the child is receiving. The child has a 50% chance of being assigned to receive placebo during the study or the active medication, Galantamine, during the study.

The child will need to be seen weekly by the study psychiatrist for the first 4 weeks of the twelve-week study, and every other week for the remaining weeks of the study. During these visits the study psychiatrist will ask the parent for feedback on his/her child’s condition and any changes that may be related to the medication, including possible side effects, such as nausea and headaches, and will check the child’s condition. The psychiatrist will also record his/her weight. These study visits will generally last approximately 30 minutes.
