The mini-mental state examination (MMSE) or Folstein test is a brief 30-point questionnaire test that is used to assess cognition. It is commonly used in medicine to screen for dementia. In the time span of about 10 minutes, it samples various functions, including arithmetic, memory and orientation. It was introduced by Folstein et al in 1975,Folstein M, Folstein S, McHugh P. Mini-Mental State. A practical method for grading the cognitive state of patients for the clinician. J Psych Res 1975;12:189–198. PMID 1202204. and is widely used with small modifications.
Various other tests are also used, such as the HodkinsonHodkinson HM. Evaluation of a mental test score for assessment of mental impairment in the elderly. Age Ageing 1972;1:233-8. PMID 4669880. abbreviated mental test score (1972, geriatrics) and longer formal tests for deeper analysis of specific deficits.
The test
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, language use and comprehension, and copying a drawing.
Interpretation
Any score over 24 (out of 30) is effectively normal. The normal value is also corrected for degree of schooling and age.Crum RM, Anthony JC, Bassett SS, Folstein MF. Population-based norms for the Mini-Mental State Examination by age and educational level. JAMA. 1993 May 12;269(18):2386-91. PMID 8479064. Low to very low scores correlate closely with the presence of dementia, although other mental disorders can also lead to abnormal findings on MMSE testing. The presence of purely physical problems can also interfere with interpretation if not properly noted; for example, a patient may be physically unable to hear or read instructions properly, or may have a motor deficit that affects writing and drawing skills.
Enforcement of the MMSE copyright
With the significant popularity of the test,Powsner S, Powsner D. Cognition, copyright, and the classroom. Am J Psychiatry. 2005 Mar;162(3):627-8. PMID 15741491. Free Full Text. the owner (Elsevier) of the Journal of Psychiatric Research (the journal in which the MMSE was published) has decided to enforce the copyright and set-up a website to sell official versions of the test.Mini-Mental State Examination.

The enforcement of the copyright on the MMSE has been compared to stealth patents, where a patent holder waits until an invention gains widespread popularity until commencing enforcement, and is thought to have subsequently impeded research in the assessment of cognitive function.
The enforcement of the MMSE copyright has led to a backlash that bears some resemblance to the one associated with Unisys' enforcement of a patent essential for the creation of gif images and has lead to more discussion about open access and open content journals.Open Access News.
