Q: Uncontrollable laughing or crying may occur during which kind of seizure?
Answer: Frontal lobe seizure
As frontal lobe deals with more advanced function of brain, its manifestations are complex. They are hard to diagnose, and often occurs during sleep. Similarly, they are often preceded by expressive fear. In Frontal Lobe Epilepsy fear is expressed on the person's face, in contrast to Temporal Lobe Epilepsy where fear is more inside the patient. Clinically, they are highly associated with tumors or vascular malformations.
