[In this pilot study parameters are found that suggest a possible link between the onset of epileptic seizures and meteorological changes. The meteorological conditions were divided into 7 different levels in terms of their sympathetic/ parasympathetic effect and were related to the onset of 816 epileptic seizures of 15 patients. The possible epileptogenic effect of rapid (within 12 hours) meteorological changes was also evaluated and 48-hour periods before and after a given seizure were also considered. A trend was found in the distribution: within two days preceding seizures parasympathetic effects tended to be predominant, within those following seizures sympathetic effects tended to dominate. Surprisingly, rapid meteorological changes did not play significant role. More essential data were obtain in individual evaluations. In just every 4th patient the sympathetic or the parasympathetic effect was predominant before the seizure onset and in just every 3rd person rapid meteorological changes culminated in the pre- or in the post-seizure 48-hour interval. The most frequently occuring meteorological effect on the day of seizures was sympathetic. It is thought that these parameters might be appropriate to demonstrate the possible link. Even so, preference is given to individual evaluation which might have an additional therapeutic significance, too.]

[Clinico-morphological correlation in common dementias]

PAPP I. Mátyás

[ln the late sixties the revelation that more than half of the dementia cases in elderly people were caused by Alzheimer's disease and not by „cerebral arteriosclerosis" gave dementia research a new impetus, which accelerated in the eighties and has nowadays become explosive and has supplied us with a mass of data almost beyond comprehension. Nevertheless, even though it is most intensively, studied elucidation of the etiology and pathogenesis of the Alzheimer' s disease is still not expectable in the near future. ln addition to Alzheimer's disease, new results basically changing our views, have been achieved in the field of the vascular dementia and in dementias with Parkinsonian syndrome. Frontostriatal circuits discovered recently have helped our understanding of the subcortical dementia in these diseases and in others. By means of neuroimaging techniques, several dementia syndromes - paramedian thalamic infarcts, the watershed infarcts and the so called Binswanger's disease - have turned out to be much more common than previously believed. Clinicopathological observations have verified the role of the damage to the limbic and paralimbic structures, frontostriatal circuits and association pathways in the pathomechanism of dementias. ]

[Typical behavior models of dealing with epilepsy - the models present between patient and members of the family]


[Four are main symptom groups described which were previously considered to be not more than an organic consequence of epilepsy. In most cases in the background of these groups a pathogenic/ pathogenetic role of typical relationship constellations between the patient and his/her relatives can be observed. These constellations are illustrated by case descriptions. It is pointed out that: 1. Epilepsy is a chronic illness in the course of which in every case certain psychodynamic events take place between the patient and his or her relatives in the immediate environment. 2. According to the present „neurological" approach and to the social expectations in the course of the patients' care the main stress is on biological events and changes. As a result intrapsychic and social-psychiatric motives are frequently manifested in the form of biological symptoms, too. 3. It follows from the above that the psychic constellation is interiorized by the patient and then he/she expresses it through somatic symptoms. At first sight these symptoms seem to be typical epileptic problems”. In actual fact, somatic „epileptologic” treatment cannot be regarded as succesful. 4. Since care is mainly based on auto- and heteroanamnestic data the phenomena discussed earlier could be highlighted only by means of the simultanious exploration of the family in question and by possible disagreement between the patient and his/her environment. 5. In order to treat the epileptic patient it is essential to consider the illness in relation to the patient and the members of the family.]

[Characteristics of gadolinium-enhancement in ischemic stroke]

KENÉZ József, BARSI Péter, KULIN Árpád, NAGY Zoltán

[Stroke is a clinical diagnosis. In acute stroke, CT is the first examination of choice to exclude hemorrhage. In ischemic stroke, MR detects the changes earlier and more exactly, than CT. Contrast-enhanced MR imaging shows specific enhancement phenomena, viz. Intravasal high signal in the vessels of the ischemic cerebral region, meningeal enhancement, transitorial, mixed type enhancement and parenchymal enhancement. Our paper is deals with the causes and diagnostic significance of the different types of these enhancement effects, and discusses some differential diagnostic conclusions. In the near future, after installing more modern MR equipment, a more exact knowledge of the pathomechanism of stroke and, as a consequence, new and more effective therapies can be expected.]

[Determination of serum C-reactive protein in the illnesses of central nervous system]


[Serum quantitative C-reactive protein concentrations were measured in 186 patients admitted with suspected neuroinfection or symptoms of other diseases in the central nervous system. The diagnoses were purulent meningitis (102), abscessus cerebri (5), meningitis basilaris (2), meningitis cryptococcica (1), sepsis (11), encephalitis (22), encephalopathia (5), autoimmune central nervous illness/disease/disorder (22), non-inflammatory central nervous disease/ disorder (12) and tumour cerebri (4). The highest values of C-reactive protein were measured in patients suffering from abscessus cerebri (250.8 +/ 64.2 mg/l), sepsis (221 +/- 16.4 mg/l) and purulent meningitis (153.0 +/- 94.59 mg/l). Serum C-reactive protein concentrations were moderately increased in viral infections (36.8 +/- 36 mg/l). The C-reactive protein level in the normal range in patients suffering from non-inflammatory and autoimmune central nervous illnesses/diseases/ disorders (4.0 +/- 1.5 mg/l or 10.0 +/- 18.5 mg/l). During our examinations the C-reactive protein levels showed both local and septicaemic reactions. C-reactive protein is considered as a valuable laboratory parameter both in diagnosings central nervous system diseases with suspected bacterial infection and in monitoring therapeutic efficiency.]

Management of bone metabolism in epilepsy

UÇAN TOKUÇ Ezgi Firdevs , FATMA Genç, ABIDIN Erdal, YASEMIN Biçer Gömceli

Many systemic problems arise due to the side effects of antiepileptic drugs (AEDs) used in epilepsy patients. Among these adverse effects are low bone mineral density and increased fracture risk due to long-term AED use. Although various studies have supported this association with increased risk in recent years, the length of this process has not been precisely defined and there is no clear consensus on bone density scanning, intervals of screening, and the subject of calcium and vitamin D supplementation. In this study, in accordance with the most current recommendations, our applications and data, including the detection of possible bone mineralization disorders, treatment methods, and recommendations to prevent bone mineralization disorders, were evaluated in epilepsy patients who were followed up at our outpatient clinic. It was aimed to draw attention to the significance of management of bone metabolism carried out with appropriate protocols. Epilepsy patients were followed up at the Antalya Training and Research Hospital Department of Neurology, Epilepsy Outpatient Clinic who were at high risk for osteoporosis (use of valproic acid [VPA] and enzyme-inducing drugs, using any AED for over 5 years, and postmenopausal women) and were evaluated using a screening protocol. According to this protocol, a total of 190 patients suspected of osteoporosis risk were retrospectively evaluated. Four patients were excluded from the study due to secondary osteoporosis. Of the 186 patients who were included in the study, 97 (52.2%) were women and 89 (47.8%) were men. Prevalence of low bone mineral density (BMD) was 42%, in which osteoporosis was detected in 11.8% and osteopenia in 30.6% of the patients. Osteoporosis rate was higher at the young age group (18-45) and this difference was statistically significant (p=0.018). There was no significant difference between male and female sexes according to osteoporosis and osteopenia rates. Patients receiving polytherapy had higher osteoporosis rate and lower BMD compared to patients receiving monotherapy. Comparison of separate drug groups according to osteoporosis rate revealed that osteoporosis rate was highest in patient groups using VPA+ carbamazepine (CBZ) (29.4%) and VPA polytherapy (19.4%). Total of osteopenia and osteoporosis, or low BMD, was highest in VPA polytherapy (VPA+ non-enzyme-inducing AED [NEID]) and CBZ polytherapy (CBZ+NEID) groups, with rates of 58.3% and 55.1%, respectively. In addition, there was no significant difference between drug groups according to bone metabolism markers, vitamin D levels, and osteopenia-osteoporosis rates. Assuming bone health will be affected at an early age in epilepsy patients, providing lifestyle and diet recommendations, avoiding polytherapy including VPA and CBZ when possible, and evaluating bone metabolism at regular intervals are actions that should be applied in routine practice.

Effects of valproate, carbamazepine and levetiracetam on Tp-e interval, Tp-e/QT and Tp-e/QTc ratio


Aim - To evaluate P-wave dispersion before and after antiepileptic drug (AED) treatment as well as to investigate the risk of ventricular repolarization using the Tpeak-Tend (Tp-e) interval and Tp-e/QT ratio in patients with epileptic disorder. Methods - A total of 63 patients receiving AED therapy and 35 healthy adults were included. ECG recordings were obtained before and 3 months after anti-epileptic treatment among patients with epilepsy. For both groups, Tp-e and Tp-e/QT ratio were measured using a 12-lead ECG device. Results - Tp-e interval, Tpe/QT and Tp-e/QTc ratios were found to be higher in the patient group than in the control group (p<0.05, for all), while QTmax ratio was significantly lower in the patient group. After 3 months of AED therapy, significant increases in QT max, QTc max, QTcd, Tp-e, Tp-e/QT, and Tp-e/QTc were found among the patients (p<0.05). When the arrhythmic effects of the drugs before and after treatment were compared, especially in the valproic acid group, there were significant increases in Tp-e interval, Tp-e/QT and Tp-e/QTc values after three months of treatment (p<0.05). Carbamazepine and levetiracetam groups were not statistically significant in terms of pre- and post-treatment values. Conclusions - It was concluded that an arrhythmogenic environment may be associated with the disease, and patients who received AED monotherapy may need to be followed up more closely for arrhythmia.

[Personalised epilepsy treatment]


[Epilepsy is one of the most common chronic neurological disease in childhood. Patients with epilepsy – even with so-called benign epilepsy – need medication for years. During this time, children go through a very big change, not only gaining weight and height, but also changing hormonal and metabolic processes. Maturation processes in different brain areas also take place at different rates depending on age. All of these should be considered when preparing a therapeutic plan. In everyday practice after the diagnosis of epilepsy, the applied drug is most often selected based on the shape and type of seizure. However, a number of other factors need to be considered when designing a therapeutic strategy: 1. efficacy (form of epilepsy, type of seizure), 2. age, gender, 3. pharmacological properties of the drug, 4. adverse drug reaction profile, 5. lifestyle (community), figure (skinny, corpulent, obese), 6. other comorbidities (nutrition, behavioral and learning problems, circulatory disorders, kidney or liver disease), 7. expected interactions with other drugs already used, 8. genetics, 9. other aspects (drug registration and prescription rules). The purpose of this article is to help to decide which antiepileptic drugs are expected to have the least side effects in a particular child with different comorbidities and which medications should be avoided if possible.]

[Epilepsy in coronavirus pandemic]


[We aim to review the impact of COVID-19 pandemic on epilepsy and epilepsy-care. While the virus has no specific link with epilepsy, it may affect the nervous system both directly and indirectly, leading to seizures in several ways. The hyper-coagulable state occurring with the infection may cause strokes leading to seizures. The infection may first manifest in the form of disturbances of consciousness and behaviour, seizures, and even status epilepticus. The interactions of antiviral/antiepileptic drugs need to be taken into account during treatment. The hypercoagulable state induced by COVID-2 infection may cause stroke, which leads to seizures. The infection can occur also as an impaired consciousness of non-epileptic origin. Interactions of antiviral/antiepileptic drugs have also to be taken into account. The pandemic itself as well as quarantines and social distancing may cause anxiety and insomnia, challenge continuous antiepileptic supply; each one carrying the risk of seizing. Young epilepsy patients with learning disabilities and mental health issues are most vulnerable, justifying their hyper-protection. The danger of infection has highlighted the role of telemedicine. Internet-based video communication may ensure full care for chro­nic patients. Those methods favour bes­­ted patients with higher education. Epilepsy does not increase directly the risk of infection, but its comorbidities may worsen the course of the disease. Brain lesions and hypoxia, stress, insomnia and fever joining the infection increase seizure susceptibility. Because the danger of infection ma­de telemedicine an essential tool of pa­tient care, education and better computer supply for those in need is crucial. ]

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


[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. ]
