Study Notes

Bedside Mental Status Examination

A bedside mental status examination is essential in neurological assessments, focusing on higher cortical functions, intellect, and memory.
The examination should include explicit testing of orientation, memory, fund of information, speech and language, praxis, calculations, visual-constructional abilities, and abstract reasoning.

Formal Assessment Tools

The Mini-Mental State Examination (MMSE) is a widely used bedside tool, consisting of 30 points:
5 points for orientation to time (year, season, month, date, and day)
5 points for orientation to place (state, county, town, hospital, and floor)
5 points for attention (serial 7s)
2 points for naming a pencil and a watch
1 point for repeating "no ifs, ands, or buts"
1 point for following a printed command
1 point for writing a sentence
1 point for copying a diagram of two intersecting pentagons
The normal range of MMSE scores depends on education, with estimates of:
19 for uneducated people
23 for graduates of elementary or junior high school
27 for high school graduates
29 for college graduates
Disadvantages of MMSE include:
Age is a factor
An abnormal score does not distinguish a focal lesion from a diffuse disorder
The test is weighted toward orientation and language
Results can be normal in patients with right hemisphere or frontal lobe damage
The test is less sensitive to early or subtle cognitive decline

Alternative Assessment Tools

The Montreal Cognitive Assessment (MoCA) tool is a 30-point test, assessing:
Executive functioning and abstraction
Visuospatial skills
Language
Attention
Verbal recall
Orientation
The SLUMS and Kokmen tests have similar designs to the MoCA

Importance of Bedside Evaluation

Bedside evaluations of cognition and memory are an integral part of the neurological examination, localizing lesions affecting higher cortical functions
Omitting a systematic evaluation of mental function can lead to missing deficits in memory, fund of knowledge, or focal deficits such as alexia, apraxia, agnosia, acalculia, or constructional impairment
