A classic example is Phineas Gage, who exhibited a change in behavior after one or both frontal lobes were destroyed by a large iron bar accidentally driven through his head (though Gage, despite conventional presentations of his case, did not exhibit the aggression, antisocial behavior, or loss of impulse control sometimes reported in patients with similar injuries). There are two main regions of the prefrontal cortex that each control various aspects of behavior and personality:

Dorsolateral prefrontal cortex
This area is associated with the impairment of the cognitive abilities that control and regulate behavior and long-term memory formation (especially relating to procedural sequence memory) when either brain damage or a lesion is present. Orbitofrontal cortex
The orbitofrontal cortex has similar functions as the dorsolateral prefrontal cortex but is thought to be mainly responsible for the ability to make choices and determine right from wrong. Social effects and quality of life
Epilepsy has a substantial impact on the quality of life of the individuals that are affected by it, yet there is lack of proper examination of social cognitive functions. Physicians and researchers are coming to understand that the impact on the quality of life of the patient is as important as the effects of the seizures. Quality of life questionnaires and other assessment tools have been created to help quantify quality of life for individual patients. They consider such factors as physical health (including numbers and severity of seizures, medication side effects etc. ), mental health, social relationships, lifestyle, role activities and life fulfillment.
Frontal lobe epilepsy (FLE) is a neurological disorder which is a subtype of the larger group of epilepsy and then focal epilepsy is characterized by brief, recurring seizures that arise in the frontal lobes of the brain, often while the patient is sleeping. It is the second most common type of focal  epilepsy after temporal lobe epilepsy (TLE), and is related to the temporal form by the fact that both forms are characterized by the occurrence of partial (focal) seizures. Partial seizures occurring in the frontal lobes can occur in one of two different forms: either “focal aware”, the old term was simple partial seizures (that do not affect awareness or memory) “focal unaware” the old term was complex partial seizures (that affect awareness or memory either before, during or after a seizure). The symptoms and clinical manifestations of frontal lobe epilepsy can differ depending on which specific area of the frontal lobe is affected.The onset of a seizure may be hard to detect since the frontal lobes contain and regulate many structures and functions about which relatively little is known. Due to the lack of knowledge surrounding the functions associated with the frontal lobes, seizures occurring in these regions of the brain may produce unusual symptoms which can often be misdiagnosed as a psychiatric disorder, non-epileptic seizure or a sleep disorder.During the onset of a seizure, the patient may exhibit abnormal body posturing, sensorimotor tics, or other abnormalities in motor skills. In some cases, uncontrollable laughing or crying may occur during a seizure.
