The impact of hypertension on executive functions & speed of processing in geriatric subjects
Journal Title: Indian Journal of Clinical Anatomy and Physiology - Year 2018, Vol 5, Issue 2
Abstract
Introduction Hypertension is a major contributor to cerebrovascular pathology causing dementia Visual reaction time gives a better index of the cortical processing of Visual Stimulus Trail Making Test provides information on visual search scanning speed of processing mental flexibility and executive functions Our objective was to compare simple and choice reaction time SRT amp CRT and trail making scores between hypertensives and normotensives geriatric male subjectsMaterials and Methods The present crosssectional study was conducted on 60 Male hypertensives and normotensives aged gt60 years with BP lt14090 mm Hg were taken as controls amp BP gt14090 mm Hg were considered as hypertensiversquos Computer programme recorded both SRT amp CRT using Deary Liewald Reation Time Tester version 310 Trail making test was used as executive function testResults Data were analysed using SPSS version 20 Unpaired ttest showed significant difference in the reaction time scores of normotensives SRT M 3664 SD 1641 CRT M 7376 SD5982 and hypertensives SRT M 4714 SD 2152 CRT M 9024 SD 5557 In addition the executive function showed significant difference between the executive ability of normotensives TMTB M 976 SD 1824 and hypertensives TMTB M 11224 SD 2012Interpretation and Conclusion The results showed that the hypertensive elderly males have a lower cognitive performance in comparison to age matched normotensives Hypertension delays the speed of processing of information in elderly hence they are at higher risk for injuries and its consequencesKeywords Aged Executive functions Hypertension Reaction Time Trail making test
