Complete seizure control is achieved in 40-50% of all epileptic patients with drug treatment, as reported in most epidemiological studies. Many effective antiepileptic drugs with a favourable profile are available in Switzerland, allowing treatment tailored to the patient's needs. Unfortunately, up to 40-50% of all patients will eventually relapse (pharmacoresistant epilepsy). These patients run a high risk of additional morbidity and mortality. Possible pharmacoresistant epilepsy should be considered early in the disease, when there is a lack of response to the first antiepileptic drug, since only 14% of those will respond to a second drug, and only 2% to a third drug if the second fails too. Epilepsy surgery is a viable option for these patients. It requires in-depth evaluation in specialized centres, and is related to complete seizure control in 50-90% of the patients, depending on the lesion type and site. Only for patients in whom surgery cannot be offered should neuromodulation treatments be considered. Today, two different approaches are approved, vagal nerve stimulation (VNS) and deep brain stimulation in the anterior thalamic nuclei (DBS-ANT). Although only a minority of patients become totally seizure-free. Both VNS and DBS-ANT represent an important adjunct in the therapeutic armamentarium. In the present review, we outline a practical approach for the different steps in therapeutic decisions and we summarise the profiles of modern antiepileptic drugs as well outcome of surgical and neuromodulatory therapies. The goal of any approach should be to obtain complete seizure control. In general, if two antiepileptic drugs are not successful, in-depth evaluation of the patient in a specialised center is strongly recommended.
正如大多数流行病学研究所报告的那样,40%-50%的癫痫患者通过药物治疗可实现完全控制癫痫发作。瑞士有许多疗效良好的有效抗癫痫药物可供使用,能够根据患者的需求进行个性化治疗。不幸的是,所有患者中最终有40%-50%会复发(药物难治性癫痫)。这些患者面临着更高的额外发病和死亡风险。当对第一种抗癫痫药物缺乏反应时,应在疾病早期考虑可能的药物难治性癫痫,因为这些患者中只有14%对第二种药物有反应,如果第二种药物也无效,只有2%对第三种药物有反应。癫痫手术是这些患者的一个可行选择。这需要在专业中心进行深入评估,根据病变类型和部位不同,50%-90%的患者癫痫发作可得到完全控制。只有对无法进行手术的患者才应考虑神经调节治疗。目前,有两种不同的方法已获批准,即迷走神经刺激(VNS)和丘脑前核深部脑刺激(DBS-ANT)。尽管只有少数患者能完全无癫痫发作,但VNS和DBS-ANT都是治疗手段中的重要辅助方法。在本综述中,我们概述了治疗决策不同步骤的实用方法,并总结了现代抗癫痫药物的特点以及手术和神经调节治疗的结果。任何治疗方法的目标都应是实现癫痫发作的完全控制。一般来说,如果两种抗癫痫药物治疗无效,强烈建议在专业中心对患者进行深入评估。
