Key result
Essential hypotension was associated with prolonged execution times in attentional tasks (p < 0.001) and decreased accuracy in working memory (p = 0.012) compared to normotensive controls.
Why the study?
Does essential hypotension impair attention and working memory compared to normotension?
Population
80 subjects, comprising 40 with essential hypotension and 40 normotensive controls.
Comparison
Essential hypotension (exposure) vs Normotensive controls

Does essential hypotension impair attention and working memory compared to normotension?
p-value: p=<0.001
Essential hypotension is associated with objective deficits in attention and working memory, independent of motor function and mood.
Duschek et al. (2005) conducted a case-control in Essential hypotension (n=80). Essential hypotension vs. Normotensive controls was evaluated on Execution times in attentional tasks (p=<0.001). Essential hypotension was associated with prolonged execution times in attentional tasks (p < 0.001) and decreased accuracy in working memory (p = 0.012) compared to normotensive controls.
