Short Description of Instrument

The Mini-Mental State Examination (MMSE) is a brief, quantitative questionnaire that was developed to identify cognitive status in adults. It has been used in many PD related studies and is a generic instrument that is administered by a trained examiner to the patient.


Scores are based on a 30 point scale with 5 subscales: orientation (10 points), registration and short-term recall (6 points), attention and concentration (10 points), language (both oral and written, 8 points); and visuospatial function (1 point). The higher the scores the greater the cognitive function. There are age-based and education-based norms for this although they are not typically used in PD.
