Study population: A total of 90 adult epileptic patients (according to the diagnosis of epilepsy in 2017, Fisher et al., 2017), 50 males and 40 females. With average age 24.5 ±5 .63.

Brief summary: Epileptic patients are plighted with limited daily activities, social dysfunction, family conflicts and cognitive impairment. Most of the studies had showed that cognitive disorders were frequent in patients with epilepsy.The cognitive impairment has been reported in around 25% of epileptic patients.

Detailed description: Cognitive consequences in epilepsy are often described in the following domains: verbal memory, language, executive functions, and attention. However, most of the studies focus on one or two domains in a relatively small sample.

Few studies have investigated the influential factors for the epilepsy-related cognitive impairment . However, most of these studies merely focused on one or a few potential factors and failed to consider possible distractions from other influential factors. Therefore, it is crucial to include more potential factors in the analysis and to rule out possible confounding interactions between factors.
