When refering to evidence in academic writing, you should always try to reference the primary (original) source. That is usually the journal article where the information was first stated. In most cases Physiopedia articles are a secondary source and so should not be used as references. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article).
If you believe that this Physiopedia article is the primary source for the information you are refering to, you can use the button below to access a related citation statement.
Description[edit | edit source]
The Mini-mental state examination is used to measure cognitive impairment in older adults. According to Folstein et al, it can be used to screen for cognitive impairment, to estimate the severity of cognitive impairment at a given point in time, to follow the course of cognitive changes in an individual over time, and to document an individual’s response to treatment.[1] [2]
- It assesses different subset of cognitive status including attention, language, memory, orientation, visuospatial proficiency.
- It has also been recommended for the screening of cognition in depressed patients[3]
- The mini-mental state examination is proprietary and takes about 10-15 minutes to administer.
When compared to participants with ischemic vascular dementia and Parkinson's disease, participants with Alzheimer's Disease demonstrated significant impairment on the Mini-mental state examination index evaluating orientation and memory, according to the findings. On the Assessing working memory and motor/constructional abilities, the ischemic vascular dementia and Parkinson's disease groups performed significantly worse than the AD patients.[4][5][6] However, it should not be used to exclusively diagnose or differentiate the different types of dementia.[7][8]
The Mini-Cog and revised Addenbrooke's Cognitive Examination are preferred alternatives to the Mini-Mental State Examination for dementia screening, and the Montreal Cognitive Assessment is a preferred alternative to detect mild cognitive impairment.[9]
Scoring and Interpretation of Scores[edit | edit source]
The Mini-mental state examination is scored on a scale of 0-30 with scores > 25 interpreted as normal cognitive status.
- Severe cognitive impairment: 0-17
- Mild cognitive impairment: 18-23
- No cognitive impairment: 24-30
Interpretation of the mental status examination must take into account the patient's native language, education level, and culture as these factors can affect perfromance.[10]
Validity[edit | edit source]
In 14 studies, the MMSE had a sensitivity of 88.3% (95% confidence interval [CI], 81.3% to 92.9%) and a specificity of 86.2% (95% CI, 81.8% to 89.7%) for dementia, with a score cutoff of 23 to 25 indicating significant impairment.[9] A more recent meta-analysis of 108 cohort studies found a sensitivity of 81% (95% CI, 78% to 84%) and specificity of 89% (95% CI, 87% to 91%)[11][2]
