Further study details as provided by Emory University:

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 ] [ Designated as safety issue: No ]

    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) ] [ Designated as safety issue: No ]

Estimated Enrollment: 300
Study Start Date: November 2012
Estimated Study Completion Date: August 2015
Estimated Primary Completion Date: June 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts
controlled hypertension
hypertension with medication controlled
uncontrolled hypertension
non-controlled hypertension
hypertensive urgency
hypertensive urgency no previous history or antihypertensives
asymptomatic normotensive
asymptomatic normotensive control group

Detailed Description:

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

  Eligibility

Ages Eligible for Study:   18 Years to 65 Years
Genders Eligible for Study:   Both
