Clustering approach to quantify long-term spatio-temporal interactions in epileptic intracranial electroencephalography.

Abnormal dynamical coupling between brain structures is believed to be primarily responsible for the generation of epileptic seizures and their propagation. In this study, we attempt to identify the spatio-temporal interactions of an epileptic brain using a previously proposed nonlinear dependency measure. Using a clustering model, we determine the average spatial mappings in an epileptic brain at different stages of a complex partial seizure.

Pilot study of fluzinamide (N-methyl-3-[3-(trifluoromethyl)phenoxy]-1-azetidinecarboxamide) in refractory partial seizures.

We conducted a pilot study of fluzinamide in 15 adults with refractory partial seizures. After a baseline period, fluzinamide was added to the existing regimen of phenytoin and carbamazepine and increased to maximum tolerated dose. Common side effects included dizziness, diplopia, ataxia, headache, nausea, and rash, resulting in patient withdrawal in six cases.
