The number of dementia patients in Thailand has been estimated to be 600,000 people in 2015. However, approximately 90 - 95 percent of the patients are undiagnosed, which represents a large diagnosis gap. The diagnosis gap impedes early intervention and hinders policy making. To help close the diagnosis gap, mass screening could be introduced. However, screening with conventional cognitive testing tools is more demanding and less cost-effective than computerized cognitive testing tools.
