Dr Alex Collie is a neuroscientist specialising
in the development of methods for measuring cognition (ie, thinking). Alex
has a PhD in psychology and is a scientific co-founder of CogState
Ltd, a world leading computerised cognitive testing company. In this
role Alex consults to many large pharmaceutical and nutraceutical
companies regarding the best methods of assessing cognition in clinical
research trials. Alex has published widely in the scientific and
medical literature on the effects of ageing on cognitive functions
including memory, attention and reaction time, and is recognised
as a world expert on the early cognitive signs of dementia. Recently,
Alex has begun investigating the development of cognition in healthy
2006 - Measuring your cognitive
is a dynamic construct that changes continuously as a person ages.
Recent studies have demonstrated that performance on cognitive tests
of memory, attention, motor function, planning and problem solving
improves rapidly until 15 years of age. Cognition then remains relatively
stable until middle age, when performance begins to become impaired
on specific tasks. As the individual ages, a gradual decline in cognitive
functions has been observed using recently developed computerised
cognitive testing methods. In some cases, these changes reflect the
early onset of a neurodegenerative condition such as Alzheimer’s
disease (AD). This presentation will discuss methods of identifying
early age-related cognitive changes and differentiating these from
cognitive changes associated with AD. Results from multiple studies
using the CogStateTM computerised cognitive test battery will be presented.
