The clinical and EEG findings are described of six children considered to have complex partial seizures of frontal lobe origin. The findings correspond generally with those reported for adult patients. Video-recordings of attacks in some cases and ictal cassette EEG recordings provided important diagnostic information. A definite frontal abnormality on neuro-imaging was seen in only one case. The seizures were closely associated with sleep, and anti-epileptic drug treatment was usually of limited value. The considerable diagnostic confusion surrounding seizures of this type, including their misdiagnosis as pseudoseizures or primary sleep disorder, is partly the result of the clinical peculiarities of this type of seizure, but also of clinicians' limited awareness of the condition.

Kindling is traditionally viewed as a chronic, focal epilepsy model which consistently induces complex partial seizures from limbic structures in animals. This study revealed that primary or exceedingly rapid secondary generalized seizures could also be kindled when stimulation was applied to the lateral geniculate nucleus, a thalamic region involved in sleep regulation and possibly also photosensitive epilepsy. Two experiments were conducted in cats. Experiment 1 compared the development of generalized tonic-clonic convulsions and associated sleep disorders following electrical stimulation of the lateral geniculate nucleus (N = 4) and the amygdala (N = 4). Experiment 2 described the effects of intermittent light stimulation on seizure thresholds in both groups. Three primary findings distinguished the epileptogenic process in those two brain regions. First, generalized electroencephalographic and clinical seizures accompanied the first afterdischarge obtained with thalamic stimulation. In contrast, focal seizures with secondary generalization appeared during a 3- to 4-week period of afterdischarge elicitations from the amygdala. Second, amygdala-kindled cats showed fewer sleep spindles during slow-wave sleep whereas cats kindled in the lateral geniculate nucleus had abnormal sleep spindles approaching spike wave-like activity. Third, only the latter cats showed reduced seizure thresholds in response to photic stimulation. Based on the anatomic substrates involved, the clinical and electrographic profiles observed during kindling and the type of sleep disturbance shown, we concluded that lateral geniculate nucleus kindling may represent primary generalized epilepsy, possibly of a photosensitive nature; alternatively, the rapid propagation of abnormal discharge was also consistent with the important role of the thalamus in secondary seizure generalization.

Frontal lobe epilepsy is an unusual form of complex partial seizures associated with behavioral changes including fear, agitation, kicking, and screaming. The seizures are often missed or mistaken for psychiatric problems or sleep disorders. We report 2 unusual patients presenting with psychosis who were found to have frequent frontal lobe seizures. Treatment of the seizures with carbamazepine resulted in complete resolution of their psychiatric symptoms. The relationship between frontal lobe seizures and psychosis is explored.

Periodic limb movement disorder (PLMD) is characterized by pathological periodic limb movements during sleep, insomnia and/or diurnal sleepiness, and the absence of another primary sleep disorder. We report a patient with complex partial seizures who developed PLMD while taking topiramate (TPM). He had no evidence of metabolic and/or other conditions inducing PLMD. He also had fragmented sleep and disruptive PLMS on polysomnography, and PLMS subsided with change of antiepileptic drug. Topiramate may modulate the dopaminergic pathway by inhibition of glutamate release, thereby inducing PLMD as observed in our patient. Although a single case does not allow any generalization, PLMD should be considered in patients complaining of insomnia and treated with TPM.
