Researchers in Minnesota report the effects in eight epilepsy patients when their health plans switched their medication from brand phenytoin to generic phenytoin, an antiepileptic drug. After the switch, the patients' seizures increased enough to require intervention. The study concluded that brand and generic phenytoin do not yield the same concentrations in some patients, and substitution should not be permitted without notifying physicians.

Relationship Between Concussion History and Symptom Reporting Explored
Researchers in Pennsylvania examined surveys of 57 collegiate male athletes that reported on their symptoms from recent concussions. It was the first concussion for 27 of the athletes, and the other 30 had a previous history of concussions. Unexpectedly, those with a previous history reported fewer symptoms immediately after the concussion than reported by those experiencing their first. Yet one week after the injury, those with a previous history reported more symptoms.
Patient Page on Concussion
A related Neurology Patient Page provides background on concussion. It also suggests that total concussion history should be considered to determine when an athlete can return to play. The Patient Page will be available for downloading from www.neurology.org on October 26, or can be obtained in advance from AAN media relations staff.

The American Academy of Neurology, an association of more than 18,000 neurologists and neuroscience professionals, is dedicated to improving patient care through education and research. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Parkinson's disease, ALS (Lou Gehrig's disease), dementia, West Nile virus, and ataxia.
