I've written in the past about how untreated obstructive sleep apnea can lower your seizure thresholds. Here's a study looking at children with seizures, that showed that they had lower white matter brain volume. There have been numerous past studies showing that untreated obstructive sleep apnea leads to reductions in brain volume and density, and even a higher incidence of small strokes through critical areas of the brain. I wonder if the parents of these children snores. Something else to think about.
