Comparative Study
Age and blood pressure measurement: experience with the TM2420 ambulatory blood pressure monitor and elderly people.
The accuracy of the TM-2420 ambulatory blood pressure monitor was assessed in elderly people. Ninety-four subjects (44 men and 50 women), aged 60-94 with systolic blood pressure (SBP) of 97-208 mmHg and diastolic blood pressure (DBP) of 45-109 mmHg, including 23 with isolated systolic hypertension, were studied in three centres. The monitor was compared simultaneously with pairs of observers using the Hawksley random zero sphygmomanometer. ⋯ Twenty-four-hour ambulatory blood pressure monitoring was carried out in 129 subjects aged 60-79; 89% of the monitoring attempted were successful with error rates of < 10%. The mean error rate was 3.8%. The device was well tolerated with only 4.7% of the subjects not completing a monitoring.

Early referral for specialist assessment is becoming more common with memory disorders and dementia: the mean Mini-Mental State Examination (MMSE) score of new patients at our clinic rose from 18.7 to 20.7 between 1986 and 1990. The clinical diagnosis of mild to moderate dementia has been recognized to be difficult, but several studies have reported cross-sectional diagnosis. We examined the number of visits required to establish a clinical diagnosis of dementia in the first 125 patients attending a Memory Disorders Clinic who had at least two visits (six months apart) and the stability of the diagnoses. ⋯ Sixteen per cent of patients interchanged between the categories of Alzheimer's, mixed and vascular dementias. Possible age-associated memory impairment progressed to dementia in six of eight cases, and depression to dementia in three cases. The diagnosis of mild to moderate dementia should not be restricted to a cross-sectional approach, but should involve serial clinical, psychological and affective assessments.
