Frontal lobe complex partial seizures in children: a form of epilepsy at particular risk of misdiagnosis.

ABSTRACT

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.
