Shortness of breath, a racing pulse, mental confusion, a heightened sense of anxiety, and a sense of impending doom can be symptoms of preeclampsia. Electrodiagnostic studies, including nerve conduction studies and electromyography, can help in the differentiation of axonal versus demyelinating or mixed neuropathy. Lumbar puncture and cerebrospinal fluid analysis may be helpful in the diagnosis of Guillain-Barr syndrome and chronic inflammatory demyelinating neuropathy. 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 During a reflex test, your muscle shortens (contracts) in response to deep tendon taps from the reflex hammer.

It is important to help patients control troublesome symptoms of peripheral neuropathy, such as severe numbness and pain, as well as to alleviate disability resulting from weakness.12 Several pharmacologic options exist to treat neuropathic pain, including some antiseizure medications (e.g., gabapentin [Neurontin], topiramate [Topamax], carbamazepine [Tegretol], pregabalin [Lyrica])13,14 and antidepressants (e.g., amitriptyline).1517 Topical patches and sprays containing lidocaine (Lidoderm) or capsaicin (Zostrix) also may relieve pain in some patients.18 Other supportive measures, such as foot care, weight reduction, and shoe selection, may also be helpful.2 Narcotics may have a role in the treatment of chronic neuropathic pain in selected patients19; candidates initially should be evaluated for their risk of substance abuse and addiction, and several nonnarcotic regimens should be tried first. Many women suffering from preeclampsia dont feel sick, and may be surprised or become frustrated when they are admitted to the hospital or prescribed bed rest since they still feel well. Mechanical ventilation should be considered in patients whose forced vital capacity is less than 20 mL per kg or is reduced by more than 30 percent of baseline, or if maximal inspiratory pressure is less than 30 cm of water.11. Lumbar puncture and CSF analysis may be helpful in diagnosing Guillain-Barr syndrome and chronic inflammatory demyelinating neuropathy; CSF protein levels may be elevated in patients with these conditions.6,7. It usually indicates a disease that involves one or more of the components of the two-neuron reflex arc itself. Biophysical profile Options for symptomatic treatment of peripheral neuropathy include antiseizure medications, tricyclic antidepressants, and topical medications. Calcium supplementation decreases the incidence of hypertension and preeclampsia, respectively, among all women (NNT = 11 and NNT = 20), women at high risk of hypertensive disorders (NNT = 2 and NNT = 6), and women with low calcium intake (NNT = 6 and NNT = 13).

When a patient presents with symptoms of distal numbness, tingling and pain, or weakness, the first step is to determine whether the symptoms are the result of peripheral neuropathy or of a lesion in the CNS, and whether a single nerve root, multiple nerve roots, or a peripheral nerve plexus is involved.

The disease is sometimes referred to as a silent killer because most people cant feel their blood pressure going up. Fetuses older than 34 weeks, or those with documented lung maturity, are also delivered without delay.7, For patients with severe preeclampsia between 24 and 34 weeks of gestation, the data are insufficient to recommend interventionist versus expectant management.47 Subspecialty consultation is indicated.48,49 Corticosteroids are administered to accelerate fetal lung maturity.7 Interventionist management advocates induction or cesarean delivery 12 to 24 hours after corticosteroid administration.

The most common treatable causes are diabetes, hypothyroidism, and nutritional deficiencies. Common vision changes include sensations of flashing lights, auras, light sensitivity, or blurry vision or spots.
