Some authors include somatomotor manifestations (SMM) among the clinical features of temporal lobe seizures in man; however, data are limited and conflicting. This study describes 101 seizures recorded during stereo-EEG explorations in 50 patients, selected on the basis of the demonstration of onset in temporal lobe structures (stereo-EEG) and the presence of lateralized SMM and/or secondary generalization (SG). SMM and SG were present in about 20% of our population of patients with temporal seizures explored with stereo-EEG, and were only rarely observed during the first 10 s (early SMM) of the seizures (less than 10%). Seizures characterized by early SMM were generally induced by electrical stimulation or chemical activation and only exceptionally spontaneous. In all cases the ictal electrical discharge also involved at an early stage extratemporal structures such as the rolandic operculum, the parietal lobe, or contralateral temporal structures. In most cases (greater than 90%) SMM represented a late (greater than 10 s) event in the ictal symptomatology. The face and the upper limb were by far the most frequently involved segments. Thirty-eight percent of seizures ended up in SG. The associated ictal symptomatology was rather poor and differed from our previous findings in temporal lobe seizures: oroalimentary automatisms were relatively rare, whereas an impairment of consciousness was observed in more than 50% of seizures. The critical electrical discharge had a long duration and always involved extratemporal structures in one or both hemispheres. The involvement of the central region could be demonstrated in all patients with deep electrodes in that region. In conclusion, SMM are not characteristic of temporal lobe seizures, and their presence indicates spreading of the critical discharge beyond the temporal lobe.

Out of 502 patients with surgically treated drug-resistant chronic epilepsy (tumour cases excluded) in 12 (2%) a clear occipital focus was found. The pattern of seizures was in most cases nonspecific and polymorphic. EEG examination and neuroradiological findings led to proper localization of the epileptogenic focus. Partial or total occipital lobectomy was performed. Follow-up from 4 to 20 years revealed a satisfactory result in 11 of the surgical cases. One patient was lost to follow-up. Brain scarring was found in the histological examination of specimens in 9 out of 12 patients. The results of the surgical treatment of occipital lobe epilepsy are much better than in other localizations of epileptogenic foci.

Cognitive functions of 24 patients with early onset parkinsonism (age of onset before 40 years) and 24 controls were investigated by a battery of neuropsychological tests. Patients were shown to be impaired in performance IQ (PIQ), conceptual ability and regulation behavior, memory, visuospatial perception, and manual dexterity. Patients were also shown to have a higher Zung Depression score. However, analysis of the testing scores appeared to indicate that only a small portion of poor performance on neuropsychological tests are depression related. The results demonstrated that patients with early onset parkinsonism, in whom the factor of aging is not as important, still show cognitive dysfunction and suggested that Parkinson's disease itself can cause cognitive impairment.
