How sex hormones and chromosomes shape epilepsy in men and women
Contributions of gonadal hormones vs. sex chromosomes in shaping sex differences in epilepsy
Using a special mouse model, researchers will see how biological sex—hormones versus chromosomes—changes seizure risk and brain injury to help adults with epilepsy.

What this research studies
This project uses a unique mouse model that separates gonadal hormone effects from sex chromosome effects so scientists can tell which drives differences in seizures. The team will record seizures with in vivo video-EEG, examine brain tissue with RNA sequencing and immunostaining, and study both acute seizure susceptibility and long-term spontaneous seizures in a model of temporal lobe epilepsy. They will compare seizure-induced brain damage and hippocampal gene expression across groups with different chromosomal and hormonal sex. The goal is to explain why epilepsy affects males and females differently and to guide future sex-specific studies and treatments.
Who could benefit from this research
Good fit: Adults with temporal lobe epilepsy or other adults interested in sex-related causes of seizures could be future candidates for human studies informed by this work.
Not a fit: People seeking immediate new treatments or those with epilepsy types unrelated to the hippocampus/temporal lobe may not directly benefit from this animal-focused project.
Why it matters
Potential benefit: If successful, this work could reveal why epilepsy differs between sexes and point toward sex-informed prevention or treatment strategies.
How similar studies have performed: Prior research shows gonadal hormones influence seizures, but using a mouse model that separates chromosome and hormone effects to study this question is a novel approach.
