estimating premorbid intellectual functioning in children and measuring change in cognitive functioning as children develop

Conditions: Child Development; Cognitive Impairment

Summary: diagnosing and documenting the presence of abnormal change in cognitive functions (such as reasoning abilities) in children over time is of upmost importance when it comes to evaluating the impact of neurological injury, disease, and interventions designed to help improve wellbeing. unfortunately however, current methods for detecting cognitive impairment and monitoring for abnormal cognitive change in children over time are seriously flawed. by assessing typically developing children's cognitive functioning at two different time points, this study intends to generate new normative data that will significantly improve measurement accuracy when it comes to evaluating the impact of neurological injury and disease on a child's cognitive abilities.

neurological injury and disease can substantially affect how children's brains work. this can severely impair cognitive abilities and general development. on a day-to-day level, completing everyday tasks, socialising successfully with peers, and getting on with school work can become much more difficult than it was before. helpfully, supports and treatments are available that can reduce the negative effects of neurological impairment on a child's cognitive functioning in order to maximise developmental outcomes. however, to deliver appropriate interventions, we must correctly estimate the impact of injury or illness on cognitive abilities and accurately measure how successful treatments are at improving outcomes. unfortunately, reliable ways of doing this simply do not exist at this time. consequently, accurate disease (effects) monitoring is seriously undermined; potentially compromising a child's medical management and, thereby, future developmental outcomes. this study intends to addresses this grave shortcoming by developing reliable ways of measuring the cognitive effects of neurological disease or injury at diagnosis and beyond. of note, by providing a mechanism to better inform clinical/medical management decisions, completion of this study will help contribute to health and social care aims of enabling children to realise their developmental potential.
