A new study seeks to understand how some people’s seizures change over time in what is known as a seizure ‘cycle’ and understand how certain triggers might increase or decrease seizure risk, perhaps giving people with epilepsy a better idea of how and why their seizures happen, and to better recognize the early warning signs. The study found that aging itself, as well as common triggers, may be contributing factors to how the medical condition affects those prone to seizures. The researchers studied the seizure diaries of more than 1,000 patients ages 2 months to 80 years and developed a new statistical model to explicitly capture the effect of factors that may drive transitions in seizure risk, looking at factors like antiseizure medications, illness, and menstrual cycles. In examining the way seizure cycles vary in people with epilepsy, the researchers found that individuals in older age groups had shorter “calm” stretches between seizures, while younger age groups had longer stretches. This work paves the way for future studies to further examine seizure cycles.
