Summary
Epilepsy and Sleep Apnea Syndrome (SAS) frequently coexist, potentially worsening outcomes for both conditions. Treating SAS may improve seizure control in epileptic patients.
Area of Science:
- Neurology
- Sleep Medicine
- Pulmonology
Context:
- The interplay between epilepsy and Sleep Apnea Syndrome (SAS) can negatively impact patient prognosis.
- Sleep fragmentation and hypoxemia in SAS may lower the seizure threshold in epileptic individuals.
Purpose:
- To investigate the association between epilepsy and SAS in adult patients.
- To evaluate the clinical characteristics and polysomnographic findings in patients with coexisting epilepsy and SAS.
Summary:
- A retrospective study of 20 epilepsy patients with SAS revealed a high prevalence of partial epilepsies (75%) and common SAS symptoms like snoring (100%) and daytime sleepiness (70%).
- Polysomnography (PSG) showed interictal epileptic discharges in 95% and disturbed sleep architecture, with a mean apnea-hypopnea index of 38.
- Risk factors for SAS in epilepsy patients included male gender, obesity, and snoring, suggesting the need for video-PSG-oximetric evaluation.
Impact:
- Highlights the importance of considering SAS in epilepsy patients, particularly those with risk factors.
- Suggests that anticonvulsant therapy might exacerbate SAS, and effective SAS treatment could potentially improve epilepsy seizure control.
