Fasting is the basis for the ketogenic diet, and intermittent fasting is emerging as a treatment for epilepsy. There are no available data about the role of Islamic fasting on seizure control. This study aims to assess the effect of Ramadan fasting on the frequency of different seizure types.
This was a prospective observational study on Muslim patients with active epilepsy intending to fast during Ramadan in the year 2019, with an average of 16 fasting hours per day. Seizure frequency for each seizure type was followed over three months, one month before (Shaaban), during Ramadan and one month after (Shawwal), after ensuring drug compliance.
Three hundred and twenty one Muslim patients with active epilepsy with median age of 33 years were included (some patients had more than one type of seizure). In Ramadan, 86 out of 224 patients with focal seizures, 17 out of 38 patients with myoclonic seizures and 6 out of 10 patients with absence seizures showed ≥ 50% reduction. In Shawaal, such improvement continued to include 83, 13 and 4 patients with focal, myoclonic and absence seizures. Focal and myoclonic seizures were significantly improved in the months of Ramadan and Shawaal compared to Shaaban. However, absence seizures were significantly improved only in Ramadan compared with Shaaban. The frequency of generalized tonic-clonic seizures did not significantly differ between the three months.
Ramadan fasting may have an improving effect, as well as a post-fasting effect, on active focal, myoclonic and absence seizures.
