A developmental insult is when normal brain development is interrupted. This could occur through an injury such as a traumatic brain injury or stroke, or could be due to other causes such as epilepsy, exposure to medication prenatally or a genetic disorder. Early childhood is a time of intense brain and skill development. If brain development is interrupted it can have a long-term impact on function, with young children often particularly vulnerable to poor outcome. The research in this group is focused on the outcomes of these insults in cognitive, behavioural and social areas. Research is also focused on the benefits of intervention for children following developmental insult.
The goal of our team is to enhance the understanding of how an insult can influence development in early childhood and the vulnerabilities of young children. Additionally, we are focused on tailoring and administering interventions for young children with brain injuries and insults.
The research activities of our team are motivated by a desire to improve understanding about the impact of these insults to the brain and the functional consequences. Current projects include:
Project 1: Longitudinal consequences of traumatic brain injury
Commencing in 1990, we recruited and followed a large group of children who sustained a traumatic brain injury (TBI) between birth and 12 years for 20 years. To date our findings have confirmed poorest outcome for i) children injured in infancy and early childhood; ii) those with more severe injury; iii) those experiencing social disadvantage. Our work has characterised the pattern of brain pathology and metabolic biomarkers following early brain insult and their links to outcomes. The study continues with a number of targeted projects currently underway with long-term follow up of the group. This project has also led us to focus on the social and behavioural difficulties, with these problems one of the most common consequences of TBI sustained in early childhood.
Our research has led to a number of intervention studies using family and child-based interventions with the aim to improve quality of life and function in children with TBI.
Project 2: Health and development following paediatric arterial ischaemic stroke
Program Lead: Dr Mardee Greenham
Contrary to commonly held views, children do not recover better than adults after stroke. The key difference between children and adults is that paediatric stroke results in changed ability to achieve, rather than the loss of, functional independence. The extent of functional impairment may not be immediately apparent following stroke, particularly in newborns and preschool children, who typically grow into their deficits. This is the first prospective, longitudinal study to examine the trajectory of recovery following paediatric stroke across multiple domains including cognition, language, motor ability, social skills, mental health and quality of life. Greater understanding of consequences of paediatric stroke will result in better-informed parents and health professionals, more targeted interventions, and better outcomes for children.
