Nocturnal frontal lobe epilepsy misdiagnosed as sleep apnea syndrome.
Some clinical features as the awakenings with feeling of choking, the abnormal motor activity during sleep and the excessive daytime sleepiness are relatively common both in obstructive sleep apnea syndrome and in nocturnal frontal lobe epilepsy. In these cases, a full-night video-polysomnographic monitoring is of the utmost importance to provide a differential diagnosis between the two conditions, and to verify, in the case of the co-existence of the two disorders, which is the one responsible for sleep disruption. In the present case reports, we described 2 patients referred to our Sleep Disorders Center with the above mentioned clinical features and with a previous clinical diagnosis of obstructive sleep apnea syndrome. After the recording of them, by means of full-night video-polysomnography, they were both diagnosed as having nocturnal frontal lobe epilepsy as the main sleep disorder and then successfully treated with carbamazepine.
