Affected persons may or may not be aware that they are behaving in an abnormal manner, depending on the patient and type of seizure. A brief period of confusion known as a postictal state may sometimes follow a seizure occurring in the frontal lobes. However, these postictal states are often undetectable and generally do not last as long as the periods of confusion following seizures that occur in the temporal lobes.There are many different causes of frontal lobe epilepsy ranging from genetics to head trauma that result in lesions in the frontal lobes. Although frontal lobe epilepsy is often misdiagnosed, tests such as prolonged EEG monitoring, video EEG and/or an MRI scan of the frontal lobes can be administered in order to reveal the presence of a tumor or vascular malformation. Unlike most epileptic EEGs, the abnormalities in FLE EEGs precede the physical onset of the seizure and aid in localization of the seizures origin. Medications such as anti-epileptic drugs can typically control the onset of seizures, however, if medications are ineffective the patient may undergo surgery to have focal areas of the frontal lobe removed. Signs and symptoms
Signs and symptoms of frontal lobe seizures may include
Head and eye movements to one side
Complete or partial unresponsiveness or difficulty speaking
Explosive screams, including profanities, or laughter
Abnormal body posturing, especially fencing position
Repetitive movements, such as rocking, bicycle pedaling or pelvic thrustingEpileptic symptoms are frequently the product of the spread of overactivation occurring within one central foci that travels to lateral brain regions thereby causing an array of symptoms.
Studies have not been done to date to determine the differential risk posed by drivers with frontal lobe epilepsy relative to the general epileptic population.Hormones and pregnancy issuesHormonal changes and pregnancy can shift seizure activity and the use of antiepileptic drugs can alter the efficacy of hormones as well as cause congenital malformations in fetuses. Seizure control in pregnant women is very important to the welfare of both the developing fetus and the mother. Hormonal shifts at puberty, with birth control and at menopause can also cause changes in the frequency and severity of seizures and must be closely monitored. Increased seizure activity is reported by 50% of women during the course of the pregnancy due to changing levels of hormones, fluids, salts and absorption and elimination of medications.EmploymentA report by the Epilepsy Foundation noted that the unemployment rate amongst people with epilepsy is 25% and in patients whose seizures are poorly controlled the rate jumps to 50%. Even though people with epilepsy are protected under The Americans with Disabilities Act, employment discrimination and high rates of unemployment due to employer attitudes still exist. A study in the UK showed that 16% of employers surveyed felt there were no jobs in their company suitable for people with epilepsy and that 21% felt that employing an epileptic would be a "major issue". Fifty percent of the employers said they had a high concern regarding employing people with epilepsy with most citing safety concerns/workplace accidents as their major issue.
