People who have had strokes often have difficulty concentrating. More than half of all stroke victims have this problem which can lead to falls and injuries. Researchers from the University of Auckland in New Zealand wanted to see if a training programme already used in people with traumatic brain injuries could help. The programme called Attention Process Training involves a psychologist guiding patients through a mental workout in which they practice sustaining their attention and focusing on more than one thing at a time. The researchers studied 78 stroke patients, half of whom got regular rehab and half of whom received 14 hours of Attention Process Training. Those who received the training did better on tests of attention and the training was found to have a "highly positive effect."
