hyperintensities were scored according to the modified Scheltens score. Significance level for the used tests is p = 0.05. Results: The mean age was 68.8 AE 3.4 years old. The distribution of gender, smoking and dyslipidemia among the 4 groups was not significant. The hypertension duration, office and 24-h ABPM BP measurements and MRI score varied significantly between the 4 groups (p < 0.0005). The hypertension duration and the average awake systolic blood pressure had the stronger impact on

... e MMSE class of the patient (R 2 = 0.87, p < 0.0005). Classifying the patients into controlled and uncontrolled hypertensives, we had a higher percentage of uncontrolled BP in every cognitive impairment class. Only 1 patient with normal cognitive function had an uncontrolled hypertension. MMSE score has a sensitivity and specificity of 94% and 83% respectively in the prediction of uncontrolled hypertension. Conclusion: We conclude that MMSE is a simple test to run in clinic and can give an idea about the degree of structural damage caused to the brain; and hence predict whether or not the patient's BP is well controlled. This would not replace the 24-hour ABPM but may help guide the clinicians to request this 24-hour monitoring. http://dx.
