RESUMO
Attention deficit hyperactivity disorder (ADHD) is one of the most common developmental disorders in school-aged children. Symptoms consistent with ADHD have been observed in 8-77 % of children with epilepsy. Researchers have been motivated to search for alternative forms of treatment because 30 % of patients with ADHD cannot be treated by psychostimulants. Several studies support the use of a multimodal treatment approach that includes neurofeedback (NF) for the long-term management of ADHD. These studies have shown that NF provides a sustained effect, even without concurrent treatment with stimulants. We aimed to assess cognitive flexibility in ADHD children with and without temporal lobe epilepsy (TLE), and to evaluate the effects of NF on cognitive flexibility in these groups of children. We prospectively evaluated 69 patients with ADHD aged 9-12 years. The control group was 26 ADHD children without TLE who received no treatment. The first experimental group comprised 18 children with ADHD. The second experimental group comprised 25 age-matched ADHD children with TLE. This group was further divided in two subgroups. One subgroup comprised those with mesial temporal lobe epilepsy (16 patients, 9 with hippocampal sclerosis and 7 with hippocampal atrophy), and the other with lateral temporal lobe epilepsy (9 patients, 5 with temporal lobe dysplasia, 3 with temporal lobe cysts, and 1 with a temporal lobe cavernoma). We treated their ADHD by conducting 30 sessions of EEG NF. Reaction time and error rates on the Trail Making Test Part B were compared before and after treatment, and significant differences were found for all groups of patients except those who had mesial temporal lobe epilepsy with hippocampal atrophy. Our results demonstrate that in most cases, NF can be considered an alternative treatment option for ADHD children even if they have TLE. Additional studies are needed to confirm our results.

Because of the relationship between rolandic, temporoparietal, and centrotemporal areas and language and auditory processing, the aim of this study was to investigate language and central temporal auditory processing of children with epilepsy (rolandic epilepsy and temporal lobe epilepsy) and compare these with those of children without epilepsy. Thirty-five children aged between eight and 14 years old were studied. Two groups of children participated in this study: a group with childhood epilepsy (n=19), and a control group without epilepsy or linguistic changes (n=16). There was a significant difference between the two groups, with the worst performance in children with epilepsy for the gaps-in-noise test, right ear (p<0.001) and left ear (p<0.001) tests, and duration pattern test--naming (p=0.002) and humming (p=0.002). In auditory P300, there was no significant difference in latency (p=0.343) and amplitude (p=0.194) between the groups. There was a significant difference between the groups, with the worst performance in children with epilepsy, for the auditory-receptive vocabulary (PPVT) (p<0.001) and phonological working memory (nonwords repetition task) tasks (p=0.001). We conclude that the impairment of central temporal auditory processing and language skills may be comorbidities in children with rolandic epilepsy and temporal lobe epilepsy.

This study aimed to determine clinical features of adult patients with gelastic seizures recorded on video -electroencephalography (EEG) over a 5-year period. We screened video-EEG telemetry reports for the occurrence of the term "gelastic" seizures, and assessed the semiology, EEG features, and duration of those seizures. Gelastic seizures were identified in 19 (0.8%) of 2,446 admissions. The presumed epileptogenic zone was in the hypothalamus in one third of the cases, temporal lobe epilepsy was diagnosed in another third, and the remainder of the cases presenting with gelastic seizures were classified as frontal, parietal lobe epilepsy or remained undetermined or were multifocal. Gelastic seizures were embedded in a semiology, with part of the seizure showing features of automotor seizures. A small proportion of patients underwent epilepsy surgery. Outcome of epilepsy surgery was related to the underlying pathology; two patients with hippocampal sclerosis had good outcomes following temporal lobe resection and one of four patients with hypothalamic hamartomas undergoing gamma knife surgery had a good outcome.

Three new aspects of epilepsy are discussed: the mesiotemporal syndrome, vagus nerve stimulation, and epilepsy and driving fitness. In recent years mesiotemporal epilepsy has been recognised as the most frequent epileptic syndrome in adults. The main clinical features are febrile convulsions during childhood, followed by characteristic focal seizures in the second decade of life. The typical seizure is characterised by an aura, followed by loss of consciousness, with motor phenomena and automatisms followed by longer periods of postictal confusion. Atrophy of the hippocampus and sclerosis are observed in MRI. The syndrome is frequently drug resistant, however, 80% of the patients are free of seizure after surgical treatment. Vagus nerve stimulation is a new option in the treatment of patients with drug resistant epilepsy (partial seizures with or without secondary generalization, Lennox-Gastaut syndrome), especially when surgical intervention is not indicated. Worldwide a total of more than 4000 patients have been treated. More than 50% reduction in the frequency of seizures can be obtained in 35-40% of drug resistant patients. Complications are rare. Finally, the issue of driving fitness and epilepsy as well as provoked seizures are discussed. The current regulations and laws are taken into consideration and revised regulations for Austria are suggested.

The Personal Philosophy Inventories of 221 university students who had learned to meditate (about 65% to 70% Transcendental Meditation) were compared to 860 nonmeditators. Meditators displayed a significantly wider range of complex partial epileptic-like signs. Experiences of vibrations, hearing one's name called, paranormal phenomena, profound meaning from reading poetry/prose, and religious phenomenology were particularly frequent among mediators. Numbers of years of TM practice were significantly correlated with the incidence of complex partial signs and sensed presence but not with control, olfactory, or perseverative experiences. The results support the hypothesis that procedures which promote cognitive kindling enhance complex partial epileptic-like signs.
