This study was planned to observe the clinical and radiological course of single small enhancing CT lesions in Indian patients presenting with new-onset-seizures. In this study, 75 patients with new-onset seizures and a single enhancing CT lesion were prospectively followed up for 1 year. All patients fulfilled the criteria of cysticercus granuloma. ⋯ In the majority of patients the lesions disappeared spontaneously and in a few the lesions calcified; hence these patients did not require anticysticercal therapy. Antiepileptic therapy was helpful in controlling further recurrences of seizures in most of the patients. A few patients experienced seizures even after disappearance of CT lesions.

Vagus nerve stimulation (VNS) is a neurophysiological treatment for patients with medically or surgically refractory epilepsy. Since the first human implant in 1989, more than 10 000 patients have been treated with VNS. Two randomized controlled studies have shown a statistically significant decrease in seizure frequency during a 12-week treatment period versus a baseline period when 'high stimulation' mode was compared with 'low stimulation' mode. ⋯ In recent years much progress has been made through neurophysiological, neuroanatomical, neurochemical and cerebral blood flow studies in animals and patients treated with VNS. Further elucidation of the mechanism of action of VNS may increase its clinical efficacy and our general understanding of some physiopathological aspects of epilepsy. Finally, VNS may become an alternative treatment for other conditions such as depression and pain.

Practice Guideline Guideline
Clinical guidelines for the management of epilepsy in adults with an intellectual disability.
Clinical guidelines exist for the treatment of chronic epilepsy and epilepsy in women (2). This publication provides guidance for the clinician investigating and managing epilepsy in adults who have an intellectual disability as defined by an Intelligence Quotient (IQ) of less than 70, onset in the developmental period and difficulties with adaptive functioning.

The successful surgical treatment of medically refractory epilepsy is based on one of three different principles: (1) elimination of the epileptic focus, (2) interruption of the pathways of neural propagation, and (3) increasing the seizure threshold through cerebral lesions or electrical stimulation. Temporal lobe epilepsy, being the most common focal epilepsy, may ultimately require temporal lobectomy. This is a case report of a 36-year-old male with drug-resistant right mesial temporal lobe epilepsy who failed to obtain seizure control after stereotactic radiosurgery to the seizure focus. ⋯ We conclude that low-dose radiosurgery doses temporarily changed the intensity and character of seizure activity, but actually increased seizure activity long-term. If radiosurgery is to be an effective alternative to temporal lobectomy for medically intractable temporal lobe epilepsy, higher radiosurgery doses will be required. The toxicity and efficacy of higher-dose radiosurgery is currently under investigation.

We describe the case of a 70-year-old patient in whom hemiconvulsive seizures occurred during metabolic derangement, multiple stroke and post-anoxic coma following cardiac arrest. We employed the methods of clinical and EEG evaluation and CT brain scan. We found that hemiconvulsive seizures were provoked following a light tactile stimulus in the left-trigeminal area and occasionally a strong tapping in the right-trigeminal area. We conclude that this type of stimulus-provoked seizure is extremely rare and could be explained by diffuse and severe brain damage.
