In 1985 a 5-year multicenter Veterans Administration Cooperative Study was completed that compared the efficacy and toxicity of phenobarbital, carbamazepine, phenytoin, and primidone in a double-blind prospective study design. A total of 622 patients, either previously untreated or undertreated, were entered into the study. Strict exclusion criteria limited confounding factors such as drug or alcohol abuse. Results showed that each of the four drugs used as monotherapy were similarly effective in the treatment of generalized tonic clonic seizures, but carbamazepine was significantly more effective in the treatment of complex partial seizures as measured by 100% control. When the results for all four drugs were combined, the data showed that approximately 80% of the patients were adequately managed on monotherapy. Differences in toxicity were the most significant factor that discriminated between these four drugs. Both carbamazepine and phenytoin were associated with significantly lower incidences of intolerable side effects than were primidone or phenobarbital. A behavioral toxicity battery was performed whenever possible prior to administration of any antiepileptic drug and at 1, 3, 6, and 12 months after initiation of monotherapy. Significant differences in performance on all subtests of the battery were found between patients with epilepsy and a control group matched by age, sex, and education. When the differential effects of all four drugs on behavioral toxicity were compared, few statistically significant differences emerged. However, carbamazepine consistently produced fewer adverse effects on tests of attention/concentration and motor performance than did the other three antiepileptic drugs.

We previously reported that drivers with epilepsy have somewhat higher age-adjusted rates of traffic accidents and moving violations than do drivers without epilepsy. We attempted to identify medical and other factors contributing to this increase. Medical records of 241 drivers with a history of seizures, representing essentially all such persons from a contiguous seven ZIP postal code area served by the Marshfield Clinic were studied. This zip code refers to a defined geographic area around Marshfield where virtually the entire population receives its care at the Marshfield Clinic and for which we have accurate records. Information abstracted from medical charts was used to identify potential risk factors for traffic accidents and violations among these drivers. Careless driving violations, alcohol or drug violations, and accidents (especially injury accidents) occurred at higher rates and speeding violations occurred at lower rates for drivers with epilepsy. Young age, unmarried state, history of multiple seizures, and lack of antiepileptic drug (AED) treatment appear to be risk factors for accidents among drivers who had a history of seizures. Male sex, psychiatric disorders, alcohol abuse, and generalized seizures or complex partial seizures (CPS) were also suggestively associated with higher risk. For moving violations, young age, male sex, unmarried state, symptomatic etiology, and history of alcohol abuse contributed to increased risk. We conclude that drivers with epilepsy appear to have identifiable risk factors for traffic mishaps, especially accidents.
