The Pediatric Stroke Research Project at the Center for Brain Plasticity and Recovery Recovery is directed by Professor Elissa L. Newport and includes researchers from Georgetown University Medical Center, MedStar National Rehabilitation Hospital, Children's National Medical Center, Johns Hopkins University, and Children’s Hospital of Philadelphia. We use assessments of language, visuo-spatial processing, and other cognitive abilities, in combination with functional brain imaging (fMRI), to study how the developing brain recovers from strokes that occur in infancy and early childhood – and how this process of recovery compares to recovery after strokes in adults. Our goal is to understand the processes underlying recovery in the developing and adult brain, and to develop techniques that can stimulate and support recovery in children and adults.

All Over the Country
With the help of stroke survivors of all ages and from all over the country, we are investigating cognitive skills and their organization in the brain, in children and adults after a stroke. Our participants have experienced a stroke at birth or early childhood and join our research studies from one year to more than 15-20 years after their stroke. Their participation allows us to observe the long-term outcomes of strokes affecting language, visuo-spatial skills, and other aspects of cognition.
Reorganization of the Brain
Long after a stroke, the brain has recovered from the immediate aftermath of the stroke and settled into a "new normal" state. In many cases, especially after stroke early in life, this new normal state is characterized by considerable functional reorganization: Functions that are ordinarily performed by brain areas injured by stroke are often now performed by other brain areas. It is this process of reorganization that we are most interested in understanding.
Hope for Rehabilitation
In most children, this "take-over " by other brain areas works surprisingly well. For example, children who have had a stroke injuring the brain’s left hemisphere language areas can nevertheless learn language. The research literature has suggested various ways in which this is possible: either by using perilesional areas of the brain (left-hemisphere areas around the injury), by using right-hemisphere brain areas, or by more diffuse and diverse processes of reorganization. However, sometimes recovery is less successful – and it is almost always less successful in adults than in children. By understanding more about the capabilities and limitations of functional brain reorganization and the conditions under which it works particularly well, we will learn how to improve the recovery of children and adults who experience a major stroke.
Some questions of interest
- Do infants and young children recover from stroke better than older children and adults, as is often claimed?
- If so, do developing brains reorganize more extensively or in different ways?
- Are specific patterns of reorganization better than others?
- Do certain cognitive functions (e.g., language) recover better than others (e.g., visuo-spatial skills)?
- How can we stimulate recovery in all children and adults to follow the best paths for successful reorganization of function?
