Neurologic diseases in pregnancy.

: Although most neurologic problems require conservative management, such as headaches and nerve compression syndromes, other demand aggressive treatment, such as plasmapheresis in Guillain-Barre syndrome and prompt surgery in those patients with hemorrhagic strokes secondary to a ruptured aneurysm or arteriovenous malformation. Myasthenia gravis, discussed in the autoimmune disease section, and epilepsy are associated with congenital anomalies, whereas the progeny of patients with multiple sclerosis are at a much greater risk than the general population of contracting this disease. Therefore, knowledge of these risks is essential in providing quality preconceptional counseling. Pregnancy provides many physiologic changes that alter the course of preexisting neurologic conditions as well as increasing the risks and morbidity of other diseases. It is for this reason that a cooperative team effort, including the obstetrician, neurologist, and, if needed, the neurosurgeon, is essential for an optimal outcome.
