Outcome measures
Primary outcome
Correlation between degree of disturbance of the cerebrovascular control system and cognitive function in former preeclamptic patients.
Secondary outcome
Correlation between presence of cognitive complaints and cognitive function (NPO-scores).
Correlation between presence of cognitive complaints and cerebrovascular control parameters.
Background summary
Although the regulation of cerebral blood flow is known to be altered during preeclampsia, little is known about the state of the control mechanisms after the experience of preeclampsia. Nevertheless, several studies report evidence for formerly preeclamptics having a higher risk to die from stroke and a shorter life expectancy. Furthermore, our previous study shows that neurovascular coupling is abnormal in a subgroup of formerly preeclamptics. The question raised now is whether abnormalities in local blood flow regulation of formerly preeclamptics are related to cognitive function and to the persistent cognitive complaints which are regularly reported.
A few studies show that cognitive function is disturbed after severe preeclampsia, but discuss that it is not known whether this effect is permanent or temporal and whether it is caused by organic damage. Our working hypothesis is that test-objectified cognitive function of formerly preeclamptics with or without subjective cognitive complaints is correlated with dynamic cerebrovascular control parameters measured by non-invasive techniques for recording cerebral autoregulation and neurovascular coupling. The major objective is to investigate whether cognitive complaints of formerly preeclamptics are caused by organic damage (measured by brain function) which may be used to predict an increased risk for future cerebrovascular complications such as stroke.
Study objective
Persistent cognitive complaints of part of the women who experienced severe preeclampsia 0.5-1.5 year ago can be objectified by neuropsychological as well as cerebral hemodynamic tests.
Study design
Single measurements within time span of 0.5-1.5 years after experience of preeeclampsia.
Intervention
No interventions tested, but correlation between parameters (cerebral blood flow regulation and cognition) in a single patient group (former preeclamptics).
Cerebral blood flow is measured non-invasively using transcranial Doppler ultasonography.
Cognition is objectified by neuropsychological test scores.
