A study involving outpatients with early stage Alzheimer’s found that their performance on some computerized tests of executive function and visual attention, including a simulated driving task, improved significantly after three months of taking cholinesterase inhibitors. Specifically, the drug treatment was associated with an improved ability to accurately maintain lane position during the simulated driving task; to accurately and quickly detect a target in a visual search task; to more quickly complete computerized mazes.
