[Oral contraceptives and neurologic complications].

Neurological complications of oral contraceptives are discussed. Cerebrovascular disorders expecially thromboembolism of the carotid or cerebral arteries are numberically the most important and result in varied symptomatology (vertigo ataxia hemiplegia hypesthesia). Migraine and vascular headache have also been linked to oral contraception by some authors while others have been unable to establish any connection. A causal relationship between ovulation inhibitors and epilepsy and multiple sclerosis has not been established. Oral contraceptives may be an aggravating factor in myasthenia which is endocrine-dependent to a certain degree. In general direct neurological effects need not be feared. Most nervous system complications of oral contraceptives are disorders of cerebral function or organic brain damage due to cerebrovascular events caused by the medication. Synergism of oral contraceptives and substances used in the treatment of neurological disorders must be considered.
