Epilepsy is a neurological disorder affecting 50 million individuals globally. Modern research has inspected the likelihood of forecasting epileptic seizures. Algorithmic investigations are giving promising results for seizure prediction. Though mostly seizure prediction algorithm uses pre-ictal (prodromal symptoms) events for prediction. On the contrary, prodromal symptoms may not necessarily be present in every patient or subject. This paper focuses on seizure forecasting regardless of the presence of pre-ictal (prodromal symptoms) using the single robust feature with maximum accuracy...

BACKGROUND/AIMS: Pain is a non-motor symptom of Parkinson's disease (PD). Few systematic studies have been carried out and there are still no guidelines on pain therapy in PD. Additionally, within the studies that do exist, gender-specific differences in pain perception are often the focus, though no consistent results have to date been obtained. The first main aim of our study was therefore to map pain in the largest PD study group to date, with the second being the analysis of the impact of different pain therapies in PD...
