<p>High blood pressure and cognitive impairment often coexist in old age, but their pathophysiological association is complex. Several longitudinal studies have shown that high blood pressure at midlife is a risk factor for cognitive impairment and dementia, although this association is much less clear in old age. The effect of blood pressure lowering in reducing the risk of dementia is only borderline significant in clinical trials of older subjects, partly due to the insufficient follow-up time. Conversely, dementia onset is associated with a decrease of blood pressure values, probably secondary to neurodegeneration. Prognostic effect of blood pressure values in cognitively impaired older subjects is still unclear, with aggressive blood pressure lowering being potentially harmful in this patients category. Brief cognitive screening, coupled with simple motor assessment, are warranted to identify frail older subjects who need a more cautious approach to antihypertensive treatment. Values obtained with ambulatory blood pressure monitoring seem more useful than clinical ones to predict the outcome of cognitively impaired older subjects. Future studies should identify the most appropriate blood pressure targets in older subjects with cognitive impairment. </p><p><strong>Riassunto</strong></p><p>Ipertensione arteriosa e decadimento cognitivo spesso coesistono in età avanzata, sebbene la loro associazione sia complessa dal punto di vista fisiopatologico. Diversi studi longitudinali hanno mostrato che elevati valori pressori in età adulta rappresentano un fattore di rischio per decadimento cognitivo e demenza, sebbene tale associazione sia molto meno chiara in età avanzata. L’effetto della terapia antiipertensiva è risultato ai limiti della significatività statistica nel ridurre il rischio di demenza negli studi di intervento su soggetti anziani, in parte a causa della durata insufficiente del follow-up. D’altra parte, l’insorgenza di demenza è associata con una riduzione dei valori pressori, probabilmente secondaria alla neurodegenerazione. L’effetto prognostico dei valori pressori in anziani con decadimento cognitivo non è stato ancora chiarito, in presenza di un possibile effetto dannoso di un trattamento antiipertensivo aggressivo in questa categoria di pazienti. Un breve screening cognitivo, associato con una semplice valutazione motoria, è raccomandato per identificare gli anziani fragili, che necessitano di un approccio più cauto alla terapia antiipertensiva. I risultati del monitoraggio della pressione arteriosa nelle 24 ore sembrano più utili della misurazione clinica per predire la prognosi degli anziani cognitivamente compromessi. Studi futuri dovrebbero identificare gli obiettivi pressori più appropriati nel trattamento di anziani con decadimento cognitivo.</p>

Objectives To evaluate the association of general and abdominal obesity with high blood pressure in young children. Methods A longitudinal study including 1796 participants from the Madrid region (Spain) with baseline at age 4 years and a follow-up 2 years later. Blood pressure, body mass index and waist circumference were measured during a physical examination. We evaluated the association between obesity at baseline and weight changes between the ages of 4 and 6 years and high blood pressure. Data were analysed using linear and logistic regressions adjusted for covariates. Results Obese 4 year olds (general or abdominal obesity) experienced an average 4–5 mmHg increase in systolic blood pressure and a 2.5–3 mmHg increase in diastolic blood pressure by the age of 6 years. Compared to children maintaining a non-excess weight (based on body mass index) during follow-up incident and persistent cases of excess weight (overweight or obesity) had an odds ratio (OR) for high blood pressure of 2.49 (95% confidence interval (CI) 1.50–4.13) and OR 2.54 (95% CI 1.27–5.07), respectively. Regarding abdominal obesity we estimated OR 2.81 (95% CI 0.98–8.02) for incident cases and OR 3.42 (95% CI 1.38–8.49) for persistent cases. Similar estimates for the waist–height ratio were observed. Individuals who experienced remission to non-excess weight did not have an increased risk of high blood pressure. Conclusions We observed an increased risk for high blood pressure among 4-year-olds who presented with persistent or incident cases of excess weight (body mass index) or abdominal obesity after 2 years of follow-up. Children with excess weight or obesity at baseline who remitted to non-excess weight did not exhibit an increased risk of high blood pressure.
