One of the world’s most popular and trusted assessments of cognitive impairment is now available as a convenient app for smartphones and tablets. Like the paper-and-pencil version, the app can be used to screen for cognitive impairment, to select patients for clinical trials research in dementia treatment, or to track patients’ progress over time. The MMSE/MMSE-2 app includes a brief instructional video that walks users through the features of the app. In addition to the original MMSE, both standard and brief versions of the MMSE-2 are available, enabling health care providers to choose the version that will suit each client. Scoring is done automatically, and patient records can be uploaded directly to an electronic medical records (EMR) system or e-mailed to appropriate personnel. Equivalent, alternate forms of the MMSE-2 decrease the possibility of practice effects that can occur over serial examinations. The app also includes norms for the MMSE and the MMSE-2, by age and education level. The MMSE/MMSE-2 app is available to qualified health care professionals from the Apple® App Store SM (for the iPhone® or iPad®) and from Google Play (for Android™ devices). The app is free—users pay only for administrations, which start at $1.25 each.
