[1] The mini–mental state examination (MMSE) is a 30-point questionnaire test used to screen for cognitive impairment. Commonly used to screen for dementia. It is also used to estimate the severity of cognitive impairment and to follow the course of cognitive changes in an individual over time. The MMSE test includes simple questions and problems in a number of areas: the time and place of the test, repeating lists of words, arithmetic such as the serial sevens, language use and comprehension, and basic motor skills. The Higher your score, the higher your function.

  Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Study terminated early due to slow accrual and lack of resources and priority due to NCI mandate of combining two consortia. Unable to fully analyze the data, or objectives, not enough patients. Not able to do statistics
