A new Italian study has offered further insight into the likelihood of epilepsy patients being unable to control their condition through the use of antiepileptic drugs (AEDs).Conducted by the Istituto di Ricerche Farmacologiche Mario Negri in Milan, in partnership with the University of Rochester in the US, the research aimed to provide a clearer view of the prevalence of drug-resistant epilepsy in an Italian population.Medical records from 123 GPs were reviewed to identify patients diagnosed with epilepsy by a neurologist between 2000 and 2008 in the northern province of Lecco, with a total of 1,773 relevant cases identified in total.According to results published in the medical journal Epilepsy & Behavior, the frequency of drug resistance was 15 per cent across all cases of active epilepsies and 10.5 per cent of newly-diagnosed cases.This was calculated to be the equivalent of a rate of 0.8 people with AED-resistant epilepsy per 1,000 members of the global population.The researchers concluded: “Our data indicates that one-sixth of patients with active epilepsy in the general population has drug-resistant epilepsy, and one in ten patients with newly-diagnosed epilepsy will develop drug-resistant epilepsy within nine years from the diagnosis.”Posted by Steve LongClick here for more articles about anti-epileptic drugs and pregnancy risks.
