Historically, many famous figures were afflicted with recurrent seizures. French Emperor Napoleon Bonaparte and chemist Alfred Nobel were among those. It is estimated that in Hong Kong, at least 30,000 people suffer from epilepsy. In 30% of the sufferers, anti-epileptic drugs cannot control epilepsy. Some of these sufferers may benefit from epilepsy surgery which removes the brain tissues responsible for causing the seizures. Evaluating whether a patient is suitable for such an operation requires complex investigations to identify the brain tissues responsible. However, in a substantial proportion of patients, results of these initial non-invasive investigations are insufficient or conflicting and hence epilepsy surgery is not recommended. To help these patients, doctors from the CUHK Faculty of Medicine now apply a new method called intracranial EEG monitoring to locate the origin of the seizure before performing surgery. （左起）心理學系名譽臨床督導吳桂生博士、外科講座教授潘偉生教授、內科及藥物治療學系名譽臨 床副教授關國良教授，以及內科及藥物治療學系名譽臨床導師梁浩雲醫生介紹新技術應用成果 (From left) Dr. Ng Kwai-sang Sam, honorary clinical supervisor, Department of Psychology; Prof. Poon Wai-sang, Professor of Surgery; Prof. Kwan Kwok-leung Patrick, honorary clinical associate professor, Department of Medicine and Therapeutics; and Dr. Howan Leung, honorary clinical tutor, Department of Medicine and Therapeutics The sophisticated method involves an operation to place electrodes on the brain surface or in the brain substance. Since this method can record electrical signals directly from the brain, it can resolve the discrepancies among findings from non-invasive investigations, and help neurosurgeons decide on the brain tissues for removal. In addition, doctors can use these intracranial electrodes to ‘map’ brain areas with important functions, such as body movement and language, so that these areas will not be removed in the operation. Up till now, over 70 patients have undergone epilepsy surgery at the Prince of Wales Hospital. The use of intracranial EEG monitoring was applied to three patients who were previously considered not suitable for surgical operation. After years of epilepsy uncontrolled by medication, these patients have now become seizure-free without post-operation complications.
