[The propagation and semiology of focal epileptic seizures. case presentations to the insula. theoretical considerations]

BALOGH Attila, BALOGH Attila ifj.

[Study objectives – The developing of diagnostical examinations in epileptology provides new challenges in seizure semiology. On the analysis of seizures it is important to examine the mechanisms of their propagation. The brain connectivity (based on the neuroimaging), the shadowing of the movement of excessive neuronal activity (based on computerized EEG and MEG methods), the cognition of the physiological and pathological brain networks are the foot- stone of the epileptic seizure propagation. The investigators prove, by means of case demonstrations of the role of the network nodes and the role of the epileptic hubs in the seizure symptomatology. Methods – The preoperative, intra and postoperative data are analised of three insular and one parietal epileptic patients in point of view of their seizure symptomes. Complex neuroimaging, noninvasive and invasive electrophysiology, intensive long-term video-EEG monitoring, computerized EEG analysis, fuctional mapping, intraoperative corticography were used. The etiology were confirmed with hystology. Results – It is observed that on seizure semiology our patients plays the insula a double role. In some cases, it is the focus of insular seizures with their symptoms difficult to identify. However, in the majority of cases and as a consequence of its rich neural connections, the insula has a peculiar property in the evolution of the symptomatogenic features of seizures. This observations are developing new relationships between the mechanism of seizure propagation and its semiological consequences. Conclusions – On epileptological point of view there are brain structures which has peculiar role in the „designe” of propagation of the epileptic excitement. The numerous new methods in neuroimaging and neurophysiology allowed the connectomical examination of the epileptic networks. The role of the epileptic diathesis is approachable with the metholdology of the brain connectivity. Theoretically the node of the epileptic network consist of the potential pathes where the localised excessive excitement can propagete. The route where the actual seizure can go adhead is determined by the actual edpileptic propensity of the above mentioned potential pathes.]

[The Good, the Bad and the Ugly ]


[Reading the title most of us (but not everyone) can recall from our memories the classic heroes of the movie of Sergio Leone and we can almost hear (or not?) the melody of Ennio Morricone. This sentence is full of strangeness, isn’t it? However it’s hardly at all sure that everyone had seen the movie (indeed certainly not) and the catching music is maybe elusive. Like or not we are related to classics of lipidology, as well. Most of the readers of this review of the three clinicians know much (but not everything!) of these topics but probably for some of them this paper will arise their further interest. We are going to separate the “inseparable”, only together functioning whole thing in order to build a model in our thinking regarding its operation. This is what we do with the scientific cognition. We are making models, simplifying indeed… (sometimes erroneously) proclaiming. Let’s throw out our (or at least try to do it) the stereotypes living inside us. Let’s talk about the “always” good HDL-cholesterol, the bad LDL-cholesterol and the ugly (or cruel) triglyceride, actually (and now the analogy is lost of the three key players of the classic western movie) about the other faces of the together ugly and bad lipoprotein(a) according to a lot of opinions! As everything is connected with everything in the human body and nothing is accidental - nothing can be only good, bad or ugly nor the Good, the Bad and the Ugly yet.]

[Screening for depression and suicidal risk in family and general medical practice]

RIHMER Zoltán, SZILI Ilona, KALABAY László, TORZSA Péter

[According to both international and national studies the point prevalence of diagnosed major depression requiring treatment is 6-10 percent in general practice. As un­treated depression is the most important risk factor for suicide, early detection and effective management of depression (especially depression which predisposes sui-cide) are critical in prevention. According to international and national studies the re-cognition of major depression in primary care significantly contributes to the decline of suicide mortality. In our article we present two short questionnaires used for re-cognising depression and acute suicide risk and we describe their use in family/ general practice. We aim to raise awareness of the need of a systematic, nationwide sui-cide prevention programme which is supported on government level as well. ]

[Behavioral and cognitive profile of corpus callosum agenesia - Review]

LÁBADI Beatrix, BEKE Anna Mária

[Introduction - Agenesis of corpus callosum is a relatively frequent congenital cerebral malformation including dysplasia, total or partial absence of corpus callosum. The agenesis of corpus callosum can be occured in isolated form without accompanying somatic or central nervous system abnormalities and it can be associated with other central nervus system malformations. The behavioral and cognitive outcome is more favorable for patients with isolated agenesis of corpus callous than syndromic form of corpus callosum. The aim of this study is to review recent research on behavioral and social-cognitive functions in individuals with agenesis of corpus callosum. Developmental delay is common especially in higher-order cognitive and social functions. Methods - An internet database search was performed to identify publications on the subject. Results - Fifty-five publications in English corresponded to the criteria. These studies reported deficits in language, social cognition and emotions in individuals with agenesis of corpus callosum which is known as primary corpus callous syndrome. Discussion - The results indicate that individuals with agenesis of corpus callosum have deficiency in social-cognitive domain (recognition of emotions, weakness in paralinguistic aspects of language and mentalizing abilities). The impaired social cognition can be manifested in behavioral problems like autism and attention deficit hyperactivity disorder.]

Psychoneuroimmunology and the embodied mind

SZABÓ Attila

One of the major philosophical aspirations in contemporary consciousness research is to find a framework of explanation that could successfully address the problem of mind-body relations. Descartes is often regarded as the father of dualism in modern philosophy of mind. Phenomenology and embodiment may dissolve the problem of dualism in the waters of the experiential features of the life-world and the subject. Recent findings in psychoneuroimmunology have shown that somato-psychic mechanisms exist through which bodily stimuli are translated into neuropsychological events resulting in alterations in certain behavioral patterns. These may as well include changes in the qualitative features of the lived body (Leib) resulting in an overall change in the subjective experience. The application of modern embodiment theories in life sciences has the potential to create a novel, fruitful and heuristic approach, which may help us unveil features of the “mind-body phenomenon” that have been hidden so far. In this paper, I will try to briefly outline a possible analytical framework on the grounds of classic - Husserlian and Merleau-Pontian - phenomenology and biomedical sciences.

[LGI1 encephalitis: the first Hungarian patient]

SZŐTS Mónika, MARTON Annamária, ILLÉS Zsolt, BAJZIK Gábor, NAGY Ferenc

[In the recent years, it has been increasingly recognised that in a group of limbic encephalitis antibodies are directed against the scaffolding protein LGI1 (Leucine-rich glioma inactivated 1), which is part of the voltage gated potassium channel (VGKC) complex on neural synapses. Patients present with seizures and subacute history of neuropsychiatric symptoms, including psychosis and changes in memory, cognition, behaviour. Faciobrachial dystonic seizures can be observed, which are highly characteristic for LGI1 encephalitis. MRI shows medial temporal abnormalities in more than half of the cases. CSF evaluation is usually normal. Hyponatremia is frequently associated and may confuse the initial diagnosis. Early recognition and prompt initiation of immunotherapies are of great importance. The clinical improvements often correlate with the antibody levels. We present the case of a 64-year old man, who responded quickly to plasma exchange and major improvement was noted within few weeks.]

[Mirror neurons and interpersonality in the paradigm of embodied mind]


[In this paper, our aim is to scrutinise the psychology and phenomenology of interpersonal relationships from an interdisciplinary viewpoint. This multi-perspectival examination has a key concept: we critically discuss the interdisciplinary dialogues and philosophical appraisals regarding the issue of mirror neurons. Empathy and resonance phenomena have philosophical, psychological, and biomedical importance. Our paper, by applying certain philosophical and empirical results of the overarching paradigm of embodiment, attempts to shed light on several semantic problems, which could come up with respect to the function of mirror-neurons. In conclusion, we would like to attempt to utilise the results of contemporary phenomenology in order to clear some semantic problems, considering the features of mirroring and resonant behaviour.]

[Roma cancer patients’ illness cognition and their attitudes toward medical treatment]


[INTRODUCTION - In this qualitative pilot study, our goal was to investigate the illness representation of gipsy cancer patients and to examine their attitudes toward medical treatment. SAMPLE AND METHODS - Deep interviews were made with 20 persons (60% female; Mage=39.2±15.1 years). The included participants approximately represented the group composition of the Hungarian Roma population. RESULTS - For most of our respondents, cancer is a frightening disease meaning some kind of punishment and the end of life. The potential causes of the disease usually remain completely incomprehensible. The participants proved to be very under-informed in relation to their treatment - even when compared to the low level of information among Hungarian cancer patients in general. In the face of the supporting presence of family members, our respondents often stated that there was nobody to share their deeper emotional problems with. About half of the patients reported on impolite and inefficient treatment attributed to prejudice against their Gipsy identity. However, deeper analyses revealed, that in most of these cases, mistreatment was a consequence of the general shortcomings of the health care system (e.g. lack of time) - being labelled as discrimination by our respondents. Almost every participant sees his/her only role in recovery merely in the participation in medical treatment - not attributing enough significance to life style changes and even less to alternative / complementary medicine. CONCLUSION - Special training to improve communication skills with gipsy patients is needed - especially for general practitioners. We also suggest preparing handouts to Roma cancer patients that provide easy-to-understand information on the medical treatments and health behaviours that serve the coping with cancer and their prevention.]
