Using the MMSE, when does a patient typically demonstrate cognitive dysfunction?

The Mini-Mental State Examination (MMSE) is a widely used tool for screening cognitive function and assessing the severity of cognitive impairment. A score of 24 or lower on the MMSE indicates potential cognitive dysfunction and suggests that the individual may be experiencing varying degrees of cognitive impairment. This threshold is based on studies that suggest scores below this level often correlate with difficulties in daily functioning and can indicate conditions such as mild cognitive impairment or dementia.

Scores above 24 are generally considered within the normal range, suggesting that cognitive function is relatively intact. Thus, for practical applications in clinical settings, a score of 24 or lower serves as a critical marker in identifying patients who may need further evaluation or intervention for cognitive issues. The classification of cognitive dysfunction is instrumental in guiding treatment decisions and planning appropriate support for the patient.
