Loss of sensation (including vibration, proprioception, temperature, and pinprick sensations) in distal extremities suggests peripheral neuropathy, as does a distal-to-proximal gradient of reflex elicitation. Pharmacologic treatment is needed to prevent maternal end-organ damage from severely elevated blood pressure (150 to 180/100 to 110 mm Hg); treatment of mild to moderate chronic hypertension does not improve neonatal outcomes or prevent superimposed preeclampsia.

With preeclampsia, the blood pressure is usually normal at the beginning of the pregnancy, but around 20 weeks gestation it starts to elevate. A potential limitation of electrodiagnostic studies is that they are able to test only the large, myelinated nerve fibers. CNS lesions may be associated with other features, such as speech difficulty, double vision, ataxia, cranial nerve involvement, or, in cases of myelopathy, impairment of bowel and bladder functions.

Main outcome measures. Adverse pregnancy outcomes related to severe preeclampsia are caused primarily by the need for preterm delivery. By convention the deep tendon reflexes are graded as follows: 0 = no response; always abnormal 1+ = a slight but definitely present response; may or may not be normal 2+ = a brisk response; normal 3+ = a very brisk response; may or may not be normal 4+ = a tap elicits a repeating reflex (clonus); always abnormal A good prenatal diet full of vitamins, minerals and the basic food groups are important for any pregnancy, as is reducing consumption of processed foods, refined sugars and caffeine. . The National High Blood Pressure Education Program Working Group on High Blood Pressure in Pregnancy has defined four categories of hypertension in pregnancy: chronic hypertension, gestational hypertension, preeclampsia, and preeclampsia superimposed on chronic hypertension. Whether the 1 + and 3 + responses are normal depends on what they were previously, that is, the patient's reflex history; what the other reflexes are; and analysis of associated findings such as muscle tone, muscle strength, or other evidence of disease.

This widening of the spiral arteries is thought to be influenced by how well the trophoblast burrowed into the uterus during early pregnancy.
