The deficits arising from having a stroke can range from paralysis and sensory loss to cognitive problems, and depend on the extent and location of the brain damage. 

One particularly devastating form of impairment, referred to as neglect, involves a loss of attention, losing the ability to focus on relevant information in the environment, and to filter out distractions. This leaves individuals unable to return to independent living.

Often the presence of attention deficits after stroke is an early indicator of a poor long-term prognosis for recovery.

There is currently no medical treatment for this debilitating condition, and sufferers often end up in high-dependency homes.

Researchers in the Cognitive Neuroscience Laboratory at QBI, led by Professor Jason Mattingley, are developing new approaches to tackling such devastating functional losses in stroke patients. Crucial research is needed to investigate a new brain imaging approach, which is aimed at better understanding the brain systems involved and is critical in developing an effective treatment for attention deficits after stroke in the long term. 

About Professor Jason Mattingley

Professor Jason Mattingley is the Foundation Chair in Cognitive Neuroscience at The University of Queensland. He is investigating new brain imaging approaches to better understand the systems involved in attention. Professor Mattingley's research is directed toward understanding the neural and cognitive mechanisms that underlie selective attention and the prioritising of sensory inputs, cognitive operations, and motor responses, which can be adversely affected following stroke.
