BACKGROUND Charles Bonnet syndrome is a rare disorder characterized by complex and recurrent visual hallucinations in elderly patients with visual pathway pathologic defects. To date, to our knowledge, it has not been described in patients undergoing surgical resection for occipital lobe epilepsy due to cortical dysplasia. OBJECTIVE To describe a patient who experienced complex visual halluci...

This study compares ictal semiology, neurological examination and scalp EEG between lateral and mesial occipital epilepsy to assess the contribution non-invasive data make in determining the epileptogenic region within an occipital lobe. We assessed seizure origin in 41 occipital patients as lateral (11 patients), mesial (20) and both surfaces (10) as indicated by subdurally recorded seizures (...

RESULTS A total of 998 vEEGs were undertaken during the study period. Of these, 128 were following a fi rst afebrile seizure: 119/128 were referred by general paediatricians and the remaining 9 by paediatric neurologists. The mean age group was 6.5 years (range 1 month to 17 years). Thirty-four of 128 children had an underlying neurodevelopmental problem. In 11 children, there was a family hist...

Occipital epilepsies often elude diagnosis as they frequently masquerade as other seizure syndromes. Visual hallucinations are the key clinical symptoms indicating an occipital focus, but may be difficult to elicit on history, especially from children, and are not always present. When visual symptoms are not prominent, the seizure semiology and scalp EEG may lead the clinician away from conside...

OBJECTIVE The Panayiotopoulos type of idiopathic occipital epilepsy has peculiar and easily recognizable ictal symptoms, which are associated with complex and variable spike activity over the posterior scalp areas. These characteristics of spikes have prevented localization of the particular brain regions originating clinical manifestations. We studied spike activity in this epilepsy to determi...

background: mesial temporal lobe epilepsy (tle) is a remediable epileptic syndrome. about 40% of patients continue to have seizures after standard temporal lobectomy. it has been suggested that some of these patients could actually suffer from a more complex epileptogenic network. because a few papers have been dedicated to this topic, we decided to write an article updating this theme. methods...
