ABSTRACT
Stereotactically guided radiofrequency thermoablation (RFTA) for epilepsy has been frequently applied over the last 40 years. Radiofrequency electrodes with temperature control function generate a coagulation lesion with clearly defined borders. In combination with high-resolution MRI imaging, this technique allows minimally-invasive ablation of periventricular nodular heterotopias, small focal type II dysplasias, and hypothalamic hamartomas. This review summarises the literature addressing this topic mainly regarding technical aspects. In essence, RFTA is a safe treatment option for patients suffering from epileptogenic pathologies visible on MRI-images.

We report on the long-term clinical outcome (up to 8 years) of 5 patients who received deep brain stimulation (DBS) of the nucleus accumbens to treat their long-lasting and treatment-resistant alcohol addiction. All patients reported a complete absence of craving for alcohol; 2 patients remained abstinent for many years and 3 patients showed a marked reduction of alcohol consumption. No severe or long-standing side effects occurred. Therefore, DBS could be a promising, novel treatment option for severe alcohol addiction, but larger clinical trials are needed to further investigate the efficacy of DBS in addiction.
