Untreated arterial hypertension in 20 men was associated with significant deficits in general neuropsychological functioning, including slower reaction times, compared to 20 normotensive controls.
Case-Control (n=40)
Is newly diagnosed, untreated hypertension associated with neuropsychological deficits in men?
Newly diagnosed, untreated hypertension in men is associated with impairments in vigilance and attention span, suggesting early generalized neuropsychological deficits.
Twenty newly diagnosed, untreated hypertensive men (diastolic blood pressure greater than 105 mm Hg) and 20 normotensive controls were given a neuropsychological battery, including tests of generalized, more global functions (eg, reaction time and full-scale IQ) and of specific functions (eg, language and visual-spatial abilities) sensitive to focal damage. Tests of specific abilities yielded no differences between the two groups. In contrast, tests of general neuropsychological functioning revealed a deficit among hypertensives, who were significantly slower on the reaction time test and had a shorter span for digits in forward order. Results suggest that arterial hypertension is associated with impairment of vigilance and attention span. Future research will determine whether this impairment is associated with the diffuse pathological changes seen in the brain of hypertensive subjects, or with a more "functional" change (eg, reduced cerebral blood flow).
Boller et al. (1977) conducted a case-control in Hypertension (n=40). Hypertension vs. Normotensive controls was evaluated on Neuropsychological functioning (generalized and specific functions). Untreated arterial hypertension in 20 men was associated with significant deficits in general neuropsychological functioning, including slower reaction times, compared to 20 normotensive controls.
