Brief summary
This is a pilot study assessing fMRI changes and neurocognitive function in women with pre-eclampsia and healthy controls. Neurocognitive testing will be done during pregnancy and after delivery up to 2-6 weeks postpartum. fMRI will be done after delivery up to 2-6 weeks postpartum. The aims of this pilot study are therefore to 1) Determine the frequency and nature of co-morbid DTI white matter patency and fMRI functional connectivity changes in women with pre-eclampsia/eclampsia and 2) Determine the relationship between DTI white matter patency and fMRI functional connectivity changes to measurable alterations in cognitive function in this patient population.

Interventions
DIAGNOSTIC_TESTNeuroimaging Procedures
Subjects will complete neuroimaging procedures at 2-6-week postpartum or during hospitalization after delivery prior to discharge, which will consist of high-resolution anatomic, perfusion and resting-brain fMRI sequences; all of which will be acquired on a 3-Tesla General Electric magnetic resonance scanner provided by the Brain Imaging and Analysis Center (BIAC) at Duke University. No contrast agent will be administered in these imaging procedures.
DIAGNOSTIC_TESTNeuropsychological Assessment Procedures
Once identified as meeting study criteria and consented for participation, parturients will be tested during hospitalization or as outpatients for controls, and at 2-6 weeks postpartum with the following cognitive battery. Wechsler Test of Adult Reading (WTAR), CANTABeclipse Computerized Cognitive Assessment Measures, Stroop Color-Word Test, Controlled Oral Word Association Test, EuroQol, Beck Depression Inventory Revised

Inclusion criteria
Severe Pre-Eclampsia defined by * Symptoms of central nervous system dysfunction (New onset cerebral or visual disturbance, such as: Photopsia, scotomata, cortical blindness, retinal vasospasm) * Severe headache (ie, incapacitating, the worst headache I've ever had) or headache that persists and progresses despite analgesic therapy * Altered mental status * Hepatic abnormality (Severe persistent right upper quadrant or epigastric pain unresponsive to medication and not accounted for by an alternative diagnosis or serum transaminase concentration ≥ twice normal, or both) * Severe blood pressure elevation (Systolic blood pressure ≥160 mmHg or diastolic blood pressure ≥110 mmHg on two occasions at least four hours apart while the patient is on bedrest (unless the patient is on antihypertensive therapy)) * Thrombocytopenia (\<100,000 platelets/microL) * Renal abnormality (Progressive renal insufficiency (serum creatinine \>1.1 mg/dL or doubling of serum creatinine concentration in the absence of other renal disease)) * Pulmonary edema 15 English-speaking pregnant controls with uncomplicated pregnancy matched by age and gestational age will be enrolled from the antenatal clinic or the labor ward.
Exclusion criteria
* History of symptomatic cerebrovascular disease with substantial residual deficit * History of alcoholism * History of psychiatric illness * History of claustrophobia * Renal failure (creatinine \> 2.0 mg/dl) * Patients with less than a 7th grade education or unable to read and thus unable complete the neuropsychological testing * Patients with bodily implants unsafe for MRI use
