“Mini-mental state”: A practical method for grading the cognitive state of patients for the clinician

TL;DR: A simplified, scored form of the cognitive mental status examination, the “Mini-Mental State” (MMS) which includes eleven questions, requires only 5-10 min to administer, and is therefore practical to use serially and routinely.

TL;DR: The Frontal Assessment Battery is easy to administer at bedside and is sensitive to frontal lobe dysfunction.
Abstract: Objective: To devise a short bedside cognitive and behavioral battery to assess frontal lobe functions. Methods: The designed battery consists of six subtests exploring the following: conceptualization, mental flexibility, motor programming, sensitivity to interference, inhibitory control, and environmental autonomy. It takes approximately 10 minutes to administer. The authors studied 42 normal subjects and 121 patients with various degrees of frontal lobe dysfunction (PD, n = 24; multiple system atrophy, n = 6; corticobasal degeneration, n = 21; progressive supranuclear palsy, n = 47; frontotemporal dementia, n = 23). Results: The Frontal Assessment Battery scores correlated with the Mattis Dementia Rating Scale scores (rho = 0.82, p p p p Conclusion: The Frontal Assessment Battery is easy to administer at bedside and is sensitive to frontal lobe dysfunction.

TL;DR: Three parallel forms of the clinical tests of the sensorium were devised, tried out and modified on two groups of 24 subjects and correlated moderately well when repeated.
Abstract: Three parallel forms of the clinical tests of the sensorium were devised, tried out and modified on two groups of 24 subjects. The final versions were further assessed by using each form in turn with 108 psychiatric patients. The three forms of tests gave scores with very similar means and standard deviations. They correlated moderately well when repeated.

TL;DR: The present paper has attempted to attack the problem of differential “memory function” by examining the discriminating power of certain test results as between “functional”, “doubtful” and “organic” groups of elderly patients, showing that the best discrimination between the groups is achieved by a simple perceptual task.
Abstract: 1. The aim of the research is to examine the relationship of certain aspects of mental functioning to the psychiatric illnesses of old age. The present paper has attempted to attack the problem of differential “memory function” by examining the discriminating power of certain test results as between “functional”, “doubtful” and “organic” groups of elderly patients. 2. The design of the present study shows that spuriously positive results may arise from inadequate control over factors contributing to the selection of the criterion groups. 3. The investigation fails to confirm, for the patients tested, the diagnostic usefulness of certain tests in common use. 4. The results fail to confirm the predictions of “Ribot's Law” as applied to memory in these elderly patients. 5. The study shows significant differences between the means of the results of the psychiatric groups on some tasks which appear to involve “memory function”. These differences cannot be accounted for merely in terms of group differences in general intelligence. The nature of the possible underlying “memory function” remains to be further examined. 6. The investigation so far shows that the best discrimination between the groups is achieved by a simple perceptual task (Bender Gestalt). 7. The study fails to show differences between groups on any of the tests which are sufficiently great to enable these tests to be immediately employed as useful diagnostic instruments.

TL;DR: It is shown that tests for senility should be short, especially those with oral questions, because of straying attention, impaired comprehension, and short retention, andPerseveration is greatly increased in senescence; it can be brought out merely by having a succession of short, varied items.
Abstract: A tentative battery of 25 short tests for the measurement of senescence is described ( cf. Table I). The scale is the result of the application of nearly 80 tests to senile patients in three London hospitals. It was administered in full to 38 patients in all, and the present findings refer to a group of 20 less seriously demented ones, with an age range of 68 to 83. The tests are classified into three groups according to the degree of difficulty experienced by the seniles (Table II). The divisions were made on the basis of a number of criteria which emerged during the working up of the results, and are only pointers to the kind of functions involved. Briefly, the most difficult tests were those in which subjects were required to break away from old mental habits and adapt to unfamiliar situations, tests of recent memory (logical), of judgment, planning, and reasoning, or embodying difficult or lengthy instructions. Less difficulty was found with such tests as rote memory, fluency of associations, simple arithmetic, and vocabulary. Performance seemed to be least affected on tests of visual recognition, old mental habits, and simple motor tasks. It is shown that tests for senility should be short, especially those with oral questions, because of straying attention, impaired comprehension, and short retention. Perseveration is greatly increased in senescence; it can be brought out merely by having a succession of short, varied items. There is a loss of steadiness and speed on the motor side. The disturbing effect of tests with a time element on the slower acting senile is noted. The present mental status of the patients is estimated on eleven tests which are scored on the (outmoded) mental age method (Table I): the average of these is between M.A. 10 and 11. This figure is compared with previous reports on the decline of intelligence. An estimate of the former mental status of each patient is made by means of efficiency quotients on part of the “Bellevue” scale. These relate each score to the average level for the peak age-group of 20 to 24 years (Table III). The use of the vocabulary score as an index of former level is discussed. A comparison of score variation within individuals with variation between individuals shows a ratio of the former to the latter of approximately 85 per cent. Variability of scores within individuals increases with age inside the patient group, also with lower intelligence. A shortened version of the scale, which takes about 40 minutes, is indicated (Table I).
