Sleep disturbances are well-documented associations in epileptic patients even before AEDs treatment, and even in non-symptomatic epilepsy. TLE group had more sleep abnormalities compared to generalized group. NREM sleep has a facilitating effect on IID especially lighter stages (stage I and II), while REM has anti-epileptogenic effect. Chronic carbamazepine and valproate monotherapy have restorative and normalizing effects on sleep pattern especially when used as monotherapy in idiopathic epilepsies, they improve subjective daytime sleepiness. Cognitive deficits are observed in epileptic patients with normal IQ, and in recently diagnosed epileptics. Untreated epileptic patients had significant excessive daytime sleepiness compared to controls. Seizure frequency still the key factor influencing patient’s perception social dysfunction
