Predictors of successful Ramadan fasting in Muslim patients with epilepsy: A prospective study

Ramadan fasting represents a challenge for both Muslim patients with epilepsy (MPWE) as well as their treating neurologists who aim to minimize the risk of fasting-related seizures. Several factors may contribute to the risk of fasting-related seizures such as the half-life of antiepileptic drugs (AEDs), seizure control before Ramadan, and sleep fragmentation. The aim of this work was to investigate these factors.

An observational prospective study included all MPWE who completed Ramadan fasting in 2019, about 16 h per day for 30 days. They were assessed regarding seizure control, AEDs, and sleep alterations using The Pittsburgh Sleep Quality Index.

The study included 430 MPWE. The majority of patients (75.58%) completed Ramadan fasting without breakthrough seizures. Patients achieved successful Ramadan fasting were significantly younger, had shorter disease duration, longer periods of seizure freedom before Ramadan, more efficient and longer sleep hours. There was no significant difference between patients receiving monotherapy regimens with short versus intermediate long t½. Maximum seizure freedom before Ramadan and sleep hours were identified as independent predictors of successful Ramadan fasting, using multivariate analysis. Every extra week of being seizure free before Ramadan and every extra hour of sleep was associated with an increase in the probability of successful Ramadan fasting by 10% and 30%, respectively.

Neurologists should guide their MPWE who wish to fast Ramadan about the risks and precautions. Proper seizure control and ensuring adequate sleep duration can increase the probability of a successful Ramadan fasting.
