Mant A, Eyland E A, Pond D C, Saunders N A and Chancellor AH B. Recognition of dementia in general practice: comparisonof general practitioners' opinions with assessments using themini-mental state examination and the Blessed dementia ratingscale. Family Practice 1988; 5: 184–188. In a study of 226 elderly residents in a retirement villagein Sydney, Australia, general practitioners' opinions aboutdementia status had high positive and negative predictive valuesand high specificity, but low sensitivity when evaluated againstthe mini-mental state examination and the Blessed dementia ratingscale. General practitioners were found to disagree with thesetwo measures more often when patients were in advanced old age,and when they considered the patients to be depressed. We concludethat the general practitioner can increase his or her sensitivityto dementia in the elderly by use of either measure.
