Antihypertensive therapy is associated with improved visuospatial, executive, attention, abstraction, memory, and recall scores on the montreal cognitive assessment in geriatric hypertensive patients.

BACKGROUND

The prevalence of Mild Cognitive Impairment (MCI) has increased over the past few decades. However, it can potentially be reversed if detected early. Early detection of MCI using the sensitive Montreal Cognitive Assessment (MoCA) might prove to be an important cog in the wheel in identifying and slowing down this morbid pandemic in hypertensive persons.

OBJECTIVES

To study the association of antihypertensive agents on cognitive scores and prevalence of MCI using the MoCA.

MATERIALS AND METHODS

This is a single-center, controlled, observational, cross-sectional study in a tertiary care teaching hospital in India. Cognitive assessment was done using the Montreal Cognitive Assessment. Data on MoCA scores were comprehensively analyzed.

RESULTS

A total of  = 210 patients ( = 105 the in study and control groups) were included in the study. The median (IQR) MoCA score (out of 30 points) in patients taking antihypertensives was 26 (25 - 27), while it was 24 (22 - 25) in the control group. There was no difference in MoCA scores between patients taking lipophilic or hydrophilic antihypertensives. Similarly, there was no difference in MoCA scores between patients taking different drug regimens.

CONCLUSION

Anti-hypertensive therapy and lower blood pressure had a statistically significant positive association with visuospatial, executive, attention, abstraction, memory, and recall MoCA scores. Patients on antihypertensive therapy also had a lower prevalence of MCI. MoCA scores were similar in patients on either lipophilic or hydrophilic drugs and were similar between patients on different antihypertensive drug classes.
