Post: MoCA Test: Detect & Manage Cognitive Impairment Early
The Mini Mental State Examination (MMSE)
Authors: Lenore Kurlowicz, PhD, RN, CS and Meredith Wallace, PhD, RN, MSN
Introduction:
Cognitive impairment is no longer considered a normal and inevitable change of aging. Despite older adults being at higher risk than the rest of the population, changes in cognitive function often necessitate prompt and aggressive action. In older patients, cognitive functioning is particularly prone to decline during illness or injury. The assessment by nurses of an older adult’s cognitive status is crucial in identifying early changes in physiological status, learning ability, and evaluating responses to treatment.
Best Tool:
The Mini Mental State Examination (MMSE) stands out as a tool that enables systematic and thorough assessment of mental status. It encompasses an 11-question measure testing five areas of cognitive function: orientation, registration, attention and calculation, recall, and language. A maximum score is 30, with a score of 23 or lower indicating cognitive impairment. Taking only 5-10 minutes to administer, the MMSE is practical for frequent and routine use.
Target Population:
The MMSE serves as an effective screening tool for cognitive impairment in older, community-dwelling, hospitalized, and institutionalized adults. A systematic, thorough, and routine assessment of an older adult’s cognitive function yields the best results.
Validity/Reliability:
Since its inception in 1975, the MMSE has been validated and extensively utilized in clinical practice and research.
Strengths and Limitations:
The MMSE is a valuable screening instrument for distinguishing patients with cognitive impairment from those without. Additionally, its repeated use allows for the monitoring of changes in cognitive status that may benefit from intervention. However, it cannot diagnose the cause of cognitive function changes and should not substitute a complete clinical assessment of mental status. Its reliance on verbal response and reading and writing means that hearing and visually impaired patients, those intubated, with low English literacy, or other communication disorders may score poorly despite being cognitively intact.
