Epilepsy is one of the most common neurological disorders that affects approx 1% of the population, of whom as many as 40% may have complex partial epilepsy, in particular, temporal lobe epilepsy (1). Despite optimal drug treatment, seizures persist in approx 35% of patients with partial epilepsy (2). Although patients with drug-resistant forms of epilepsy can undergo resective surgery, many patients cannot be treated surgically because of unacceptable risks for loss of brain functions (3). In the search for new therapeutic approaches, the local release of adenosine from intracerebrally grafted cells was evaluated. Thanks, silicon_shaman!
