Material and Methods: 40 adult patients with Temporal Lobe Epilepsy (TLE) and 86 healthy individuals were included. The qualitative and quantitative aggressiveness assess- ment was made with Buss-Durkee Hostility Inventory. The gender role behavior was measured with Bem Sex Role Inventory. Results: Patients with TLE didn’t differ from healthy subjects on the total scores of motor and attitudinal hostility components, but scored higher on subscales “resentment” and “guilt”. The comparative gender analysis showed there were no phenomenological differences in people with TLE. Assault dominated in healthy male subjects, resentment—in healthy female subjects. The prevalence of feminine social gender type was significantly higher in people with TLE in comparison to healthy people (55% vs. 26%, p 0.01). In patients with TLE, the number of masculine traits positively correlated with indirect hostility subscale and attitudinal hostility component scores. In healthy subjects, the masculine traits positively correlated with assault.展开更多

The purpose of our work was to estimate the most common types of primary headache syndromes and its relation to seizure timing in epileptic patients in Upper Egypt. Patients & Methods: In a cross-sectional study, we evaluated headaches in 100 consecutive patients with idiopathic epilepsy attending the neurology outpatient clinic and the epilepsy clinic at Sohag university hospital by complete medical history, physical and neurologic examination EEG and CT brain. Results: Of our study population, 78% of patients with epilepsy reported headaches. Migraine occurred in 70.6% of patients with headache followed by tension-type headache in 25.58% of patients and other types of headaches occurred in 2.56% of patients. There were 8 patients (10.1%) had a pre-ictal headache, 52 patients (66.5%) had a postictal headache and 39 patients (50%) had an interictal headache. In our study, we found that the occurrence of headache being linked to the female sex, lower mean age, lower mean age at the onset of epilepsy, focal epilepsy, longer duration of epilepsy, high frequency of seizures and the use of polytherapy of antiepileptics. Conclusion: Headache especially migraine is an important comorbidity of epilepsy and should receive more attention especially in female patients, patients with younger age, lower mean age at epilepsy onset, longer duration of the disease, patients on polytherapy, patients with higher frequency of seizures and patients with focal epilepsy.展开更多

SEEG signals reflect two types of paroxysmal activity： ictal activity and interictal activity or interictal spikes （IS）. The relationship between IS and ictal activity is an essential and recurrent question in epiletology. In this paper, we present a distributed and parallel architecture for space and temporal distribution analysis of IS, based on a distributed and collaborative methodology. The proposed approach exploits the SEEG data using vector analysis of the corresponding signals among multi-agents system. The objective is to present a new method to analyze and classify IS during wakefulness （W）, light sleep （LS） and deep sleep （DS） stages. Temporal and spatial relationships between IS and seizure onset zone are compared during wakefulness, light sleep and deep sleep. Results show that space and temporal distribution for real data are not random but correlated.展开更多
