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.

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.

  • 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
