Frontal lobe seizures are seizures that originate in the front of the brain. Epilepsy symptoms can vary depending on what part of the brain is involved. Frontal lobe seizures may produce unusual symptoms that can appear to be related to a psychiatric problem or a sleep disorder.
Frontal lobe seizures often occur during sleep and may feature bicycle pedaling motions and pelvic thrusting. Some people scream profanities or laugh during frontal lobe seizures.
In many cases of frontal lobe seizures, brain wave tests (electroencephalograms) may not show the changes characteristic of epileptic seizures that originate elsewhere in the brain. Medications usually can control frontal lobe seizures, but surgery is an option if anti-epileptic drugs aren't effective.
