Air Pollution a Seizure Trigger for Patients With Epilepsy
Elevated concentrations of carbon monoxide (CO) due to air pollution increases the risk of epileptic seizures, a unique new study suggests. The link between daily outdoor CO exposure and seizure risk was particularly evident for subclinical seizures ― those in patients with abnormal electroencephalography (EEG) signals but no clinical symptoms.
@debniv Emerging evidence indicates air pollution affects brain health and may increase the risk of hospitalization or outpatient visits for epilepsy. However, little is known about the effect of pollution on the occurrence of epileptic seizures. The study used two independent long-term seizure datasets ― the NeuroVista (NV) study and the Seer App seizure diary (SD). In the NeuroVista study, researchers recorded continuous intracranial iEEG from patients with refractory focal epilepsy who had been implanted with a personal seizure advisory device that wirelessly recorded seizures on an external device.
