Advances in telecommunications concerning epilepsy.
Telemedicine is a rapidly expanding discipline. Looking back on a long tradition of telemetric measurement and transmission of brain electrical data, one might ask how relevant telecommunication techniques have become for clinical work in epileptology. In principle, communication can be either between patient and doctor or between doctor and doctor. The former includes telephone reports on frequency and severity of seizures and on mental and physical state. Because of the special problems of patients with epilepsy, the need for traveling should be minimized. To maintain close contact, telemetric transmission of electroencephalograms (EEG), seizure video-registration, and monitoring of anti-epileptic drug (AED) blood levels from home are desirable, but the technical tools now available are not of sufficiently high performance for these applications. However, physicians and medical units can communicate using high-rate data transfer. There are major problems with this technology. Transfer rates using the internet are not fixed. Moreover, using six digital telephone lines simultaneously, good-quality transmission of a 3-min video may take more than 1 h, restricting interactivity. In contrast to imaging (e.g., magnetic resonance imaging), there is no generally accepted protocol for handling EEG/electrocorticography data. There are also legal problems relating to the responsibility for failures and safety of personal or medical data. Nevertheless, the expenses of installation and use of such equipment appear justified by the expected benefits, for the patients (avoiding travel and multiple investigations, checking diagnosis and therapy, amending quality of life), for the physician (sparing equipment and manpower, accelerating and improving diagnosis), for the epilepsy center (increased database for expert systems, improved logistic and data storage) and, finally, for insurance providers (reduced overall costs). When the neurosurgical procedure is remote from the place of presurgical evaluation, telecommunication should be obligatory.
