Frontal Lobe Epilepsy
Partial seizures beginning in the frontal lobe may produce weakness or the inability to use certain muscles, including the muscles that make it possible to talk. Sudden thrashing movements during sleep are also characteristic of frontal lobe epilepsy; as is posturing with the head jerking to one side, and the arm rising with it into a brief, frozen state. Sometimes a generalized convulsion follows the slow march of these movements.
Complex partial seizures in the frontal lobe have some distinct features in contrast to those in the temporal lobes. They usually last less than a minute, are less likely to be followed by confusion or fatigue, and often occur in a series or cluster.
Frontal lobe epilepsy has significant social effects because the seizures it generates are more likely to involve brief episodes of screaming, bicycling movements, or even movements suggestive of sexual activity. Treatment includes medication and, in some cases, surgery.
