Brain Injury, Fetus and Neonate

The researchers are investigating a new treatment for white matter injury, which is a common type of brain injury in premature babies. The drug, clemastine, is experimental. This means that the drug is not approved by the Food and Drug Administration (FDA) for the treatment of white matter injury. The main purpose of this study is to learn whether clemastine is safe to give to infants with white matter injury. The researchers also want to understand how much clemastine gets into an infant's body when the medication is taken by mouth, and how long it stays in the body.

The goal of this replicated single case experimental study using a randomized multiple baseline design across participants and goals is to enable children/adolescents (aged 8-16 years) with developmental coordination disorders and/or executive function deficits following an acquired or congenital brain injury, to achieve their occupational goals. The aim is to make them more independents and autonomous in their daily lives. To achieve this, we're going to offer them an intensive group CO-OP (Cognitive Orientation to daily Occupational Performance Approach) rehabilitation training, and actively involving the parents. The main questions it aims to answer are: * To evaluate the improvement in occupational performance\* (and its maintenance over time) following intervention using the CO-OP Approach. \*Occupational performance is a person's ability to choose, organize and engage in meaningful occupations that give them satisfaction. These occupations, determined by culture and corresponding to their age group, enable them to take care of themselves, have fun and contribute to the social and economic fabric of the community. * To gather parents' experiences of supporting their child during the CO-OP intervention and its follow-up phase. Participants will be asked to identify 3 goals that they would like to achieve with the CO-OP Approach. The CO-OP intervention will take the form of two half-days a week for 5 weeks, with 1 hour 30 minutes of individual CO-OP sessions and 1 hour 30 minutes of group sessions.
