Purpose: This study aimed to identify the long-term cognitive impairments arising from Hypoxic Ischaemic Brian Injury (HIBI) in a group of patients at least one year post insult. The long term psycho-social impact and carer burden associated with HIBI were also investigated. Method: A case series design was employed to facilitate detailed analysis of individual profiles. A battery of neuropsychological measures was administered to all participants. Cognitive domains assessed included premorbid and current IQ, visual and auditory recognition, immediate and delayed recall, auditory and visual at

Abstract:
Perinatal hypoxic ischemic (HI) injury is a leading cause of long-term neurological complications in newborn babies. Matrix metalloproteinases (MMPs) are a family of endopeptidases that are capable of degrading the extracellular matrix (ECM) components. They are considered to be integral in many physiological processes. However, recently it has been demonstrated that the inappropriate activity of these proteases, particularly MMP-2 and 9, contribute to the pathogenesis of cerebral ischemia in the adult brain. Given that ECM disruption is frequently observed following injury to the developing

Abstract:
Very preterm birth disrupts development of the brain and enhances its vulnerability to injury, resulting in neurological impairments ranging in severity from cerebral palsy to mild cognitive deficits. Currently there is no treatment available. Unilateral hypoxic-ischemia (HI) in the three day old rat is well established as a model of brain injury in infants born at 22 to 26 gestational weeks. However, it is inherently variable. I show that this injury results in short term neurological deficits which may be capitalised upon for allocation of pups into treatment studies. After it is inju

Varying the time interval between endotoxin administration and hypoxia-ischemia demonstrated that LPS given between 4 and 12 hours before hypoxia-ischemia had a sensitising effect on subsequent hypoxia ischemia.

In newborn infants, birth asphyxia represents the predominant cause of brain injury. These infants will later exhibit neurodevelopmental disabilities or a more major cerebral palsy. Prevention of adverse outcomes requires an understanding of the way in which these deficits develop.
