Isolated systolic hypertension. Another disincentive to treatment is removed

The treatment of hypertension in older people and its effect on cognitive function

The benefits of antihypertensive drug therapy for older people have been clearly established. Meta-analysis suggests a 12% reduction in all-cause mortality, a 20% reduction in coronary heart disease and a 36% reduction in stroke. The absolute benefits of treatment are great due to the high incidence of vascular disease among older people. Clinicians may nevertheless have been deterred from initiating treatment because of concerns regarding adverse effects on cognition, mood, functional ability and quality of life. Recent evidence from randomised controlled trials suggests that these concerns are groundless. In the light of this evidence it is therefore disturbing that up to 50% of all older people with hypertension may remain untreated; and in over 50% of those who are treated, blood pressure may be inadequately controlled.
