Control of focal impaired awareness seizures with an oral appliance in a patient with sleep apnea


Focal impaired awareness seizure (FIAS) is a clinical phenomenon with a prevalence of 0.8% that manifests as epileptic discharges commonly located in the amygdala-hippocampal complex. It can cause visual delusions and olfactory, auditory, or affective hallucinations [1]. Obstructive sleep apnea (OSA) is common in patients with epilepsy [2]. Despite their limitations, some studies have revealed an important relationship between OSA and refractory epileptic seizures (RES), as well as between OSA improvement and a corresponding RES improvement with adequate continuous positive airway pressure (CPAP) [3].
