The purpose of this study is to study the impact of blood pressure on cognitive performance.
||Observational Model: Case Control
Time Perspective: Prospective
||The Effects of Blood Pressure on Cognitive Function: Examining the Use of Bedside Neuropsychological Testing During Acute Hypertensive Events
Primary Outcome Measures:
- DETECT neurocognitive outcome scores (Z-scores) in association with blood pressure measures and retinal pathology (isolated retinal hemorrhage, grade III/IV hemorrhagic retinopathy) [ Time Frame: 12 months ]
We aim to determine the correlation (if any) between the severity of blood pressure and DETECT neurocognitive outcomes as well as the correlation (if any) between known Hypertensive retinal disease and DETECT neurocognitive outcomes. Appropriate statistical analysis will be performed to compare clinical retinal findings, BP values, and DETECT neurocognitive test outcomes.
Subject level data will only be collected on the day of Emergency Department presentation. Subjects will not be followed after their initial enrollment. The study duration is projected for 12 months
Secondary Outcome Measures:
- Variance of DETECT scores (Z-score) attributed to reading level [ Time Frame: One year study periord (12 months) ]

asymptomatic normotensive control group
Four groups will be evaluated for possible impact of blood pressure on cognitive performance and retinal damage.
