[EFFECTS OF ANTIEPILEPTIC DRUGS ON MOOD OF PEOPLE WITH EPILEPSY]

RAJNA Péter

[This article deals with the effect of antiepileptic drugs on mood when applied in epiletic patients. The author points that depressive symptoms occur significantly more frequently in epilepsy and there are more common factor in the mechanism of action of the antiepileptic and antidepressive agents. The relevant literature is surprisingly poor. Primary and large analysis regarding affective disorders coexisting with epilepsy is still lacking. From this aspect some antiepileptic drugs have not been investigated at all. The consequences of the papers originates from indirect sources like adverse events profiles of the study drugs or from psychometric tests performed for avoiding exclusion criteria of psychological nature. On the other hand the paper deals also with the difficulties of such kind of investigations concerning the classification of depressive signs presenting with epilepsy, special considerations of inclusion of appropriate patients and particular limits of the measuring and follow-up of the observed effect. As the result of the detailed analysis of the literature the author recommends lamotrigine, carbamazepine and oxcarbazepine as first choice antiepileptic drug for epileptic patients suffering from depressive disorder, too. On the contrary, phenobarbital, topiramate and vigabatrin are able to worsen the affective symptoms. Aimed, randomized, controlled studies are necessary for recognizing the whole spectrum of psychotropic effects of antiepileptic drugs and for their successful and individually tailored application in patients in their comorbide states. Author calls the attention for the importance of the treatment of depressive states frequently occurring in epileptic patients. These symptoms modify the compliance of the patients and are able to influence even the epileptic process itself.]

[POSSIBLE ROLE OF THE BASAL GANGLIA IN THE GENERATION OF THE N30 POTENTIAL OF THE MEDIAN NERVE SOMATOSENSORY EVOKED POTENTIALS]

BENICZKY Sándor, NAGY Helga, VARGA Edina, VÖRÖS Erika, KÉRI Szabolcs, VÉCSEI László

[Background and purpose - The origin and afferentation of the frontal N30 component of the median nerve somatosensory evoked potentials (SEPs) have not yet been fully elucidated. The aim of this study was to assess the possible selective impairment of the N30 component in patients with lacunar infarcts of the basal ganglia as compared to patients with lacunar infarctions sparing the basal ganglia and to a group of healthy subjects. Methods - Median nerve SEPs were measured in ten patients with lacunar infarctions of the brain (but no cortical atrophy or leukoaraiosis) and 13 healthy volunteers. Four patients had lacunar infarctions affecting the basal ganglia and 6 patients had lesions affecting other structures. Results - In two patients with lesions affecting the head of the caudate nucleus, there was no identifiable N30 component on the affected side. In one patient with bilateral lesions of the globus pallidus, the amplitude of the N30 component was significantly reduced. In one patient with lesion of the tail of the caudate nucleus, the N30 component was unaffected. The amplitude of the N30 component was also reduced in two patients with frontal subcortical white matter lesions. In all the other subjects, we recorded normal N30 components on both sides. Conclusion - Our results further support the importance of the basal ganglia, especially the head of the caudate nucleus in the generation of the N30 component of the median nerve SEPs.]

[IDIOPATHIC NOCTURNAL FRONTAL LOBE EPILEPSY - AN UNUSUAL EPILEPSY SYNDROME]

HALÁSZ Péter, SZŰCS Anna, KELEMEN Anna

[This paper provides an overview of the development of conceptions about nocturnal frontal lobe epilepsy syndrome and describes the electro-clinical characteristics, the identity of the genetic and sporadic variant, and the relationship of the EEG and clinical signs with NREM sleep specific features. The differential diagnostic difficulties and open questions on the pathomechanism are emphasized especially in relation with the lack of epileptiform EEG signs, circumsribed seizure onset zone and cognitive deficits. The relationship of frontal automatisms and NREM parasomnias are also discussed in relation of the place of nocturnal frontal lobe epilepsy among other epilepsies.]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

Evaluation of anxiety, depression and marital relationships in patients with migraine

DEMIR Fıgen Ulku, BOZKURT Oya

Aim - The aim of this study was to evaluate the frequency and characteristics of attacks in patients with migraine, to determine the effects of anxiety or depressive symptoms, and to evaluate the marital relationships of patients with migraine. Method - Thirty patients who were admitted to the neurology outpatient clinic of our hospital between July 2018 and October 2018 and were diagnosed with migraine according to the 2013 International Headache Society (IHS) diagnostic criteria were included in this cross-sectional study. Age, sex, headache frequency and severity, depressive traits, marital satisfaction and anxiety status were examined. We used the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Maudsley Marital Questionnaire (MMQ) and Visual Analogue Scale (VAS) for measuring relevant parameters. Results - The mean severity of migraine pain according to VAS scale was 6.93 ± 1.41 and the mean number of migraine attacks was 4.50 ± 4.24. The mean BDI score of the patients was 12.66 ± 8.98, the mean MMQ-M score was 19.80 ± 12.52, the mean MMQ-S score was 13.20 ± 9.53, the mean STAI-state score was 39.93 ± 10.87 and the mean STAI-trait score was 45.73 ± 8.96. No significant correlation was found between age, number of migraine attacks, migraine duration, migraine headache intensity, and BDI, STAI and MMQ scores (p>0.05). But there was a positive correlation between MMQ-S and scores obtained from the BDI and STAI-state scales (p<0.05). Conclusion - In this study more than half of the migraine patients had mild, moderate or severe depression. A positive correlation was found between sexual dissatisfaction and scale scores of depression and anxiety.

[Interdisciplinary approach of vestibular system impairment]

PONGRÁCZ Endre

[In the first part of this review the definition of vertigo/dizziness was discussed. The major difference between the two signs is the exsistence of the direction, which is specific for vertigo. Dizziness is a frequent complaint in the clinical practice. Its frequency is increasing with advance of age, to intimate the play of declining cognitive process in the pathogenesis of its. The popular health significance of vertigo is in the rowing number of the patients. The onset of the most cases with acute vertigo appears between secundums and minutes so the patients will be provided in circumstances of emergency department. First of all three form schould be take into account: neuronitis vestibularis, benign paroxysmal positional vertigo and Meniere syndrome. Without tipical periferal signs of vertigo, central cause should be searched, principally stroke (lysis possibility). The differential diagnose of the different dizzeness/vertigo forms according to the elapsed time of the onset or congenital and acquired nystagmus was created in tables. The recommendations of the therapy of acute and chronic dizziness/ vertigo syndroms are, lack of results of evidence based trials doubtful. The more often used drugs based on clinical trials are discussed as vinpocetine, betahistine and piracetam. The in vitro and in vivo data suggest that the last molecule is eligible to use both in periferal and central type of vertigo syndroms.]

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]

RAJNA Péter

[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]
