Background - Acute mortality rate of stroke in Hungary is significantly higher than in Western Europe, which is likely to be partially attributable to suboptimal treatment. Subjects and methods - We examined the use of acute vascular imaging and mechanical thrombectomy for acute ischaemic stroke patients. We collected data on 20 consecutive patients from Hungarian stroke centres before 31st August 2016. Results - Out of the reported 410 patients, 166 (40.4%) underwent CT angiography and 44 (10.7%) had mechanical thrombectomy. Conclusion - Only about 1/3 of acute ischaemic stroke patients eligible for thrombectomy actually had it. The underlying reasons include long onset-to-door time, low utilization of acute vessel imaging and a limited neuro­intervention capacity needing improvement.

Vestibular evoked myogenic potential responses in Parkinson’s disease

CICEKLI Esen, TITIZ Pinar Ayse, TITIZ Ali, OZTEKIN Nese, MUJDECI Banu

Background - Our objectives were to determine the differences in the vestibular evoked myogenic potential (VEMP) responses in patients diagnosed with early staged idiopathic Parkinson’s disease (PD) compared to the normal population and evaluate the vestibular system disorder causing balance-posture disorders. Second aim of this study was to investigate caloric test responses particularly in early staged PD compared to normal popu­lation. Material and methods - Thirty patients (14 females and 16 males; mean age, 60.6 ± 13.1 years) diagnosed with idiopathic PD and 28 healthy subjects (20 males and 8 females; mean age, 59.1 ± 6.4 years) were included. The patient and control groups were subdivided according to their age, gender and the patient group was subdivided according to onset time of the Parkinson symptoms, Hoehn-Yahr staging. The subgroups were compared for VEMP and caloric test responses. Results - There were no significant differences between the study and control groups for right and left VEMP measurements. Patients over 60 years and under 60 years did not show significant differences in terms of right and left mean VEMP measurements. However, P1 amplitude was significantly lower in patients over 60 years old (P = .004). Gender, disease duration, BERG balance scale and Hoehn-Yahr stage had no effect on the VEMP amplitudes. There was no significant correlation with the side of Parkinsonian symptoms to the side of canal paresis (P = .566) and the side on which no VEMP response was obtained in caloric test. Conclusion - VEMP responses were not different between PD and healthy subjects. VEMP P1 amplitude was decreased with age in PD group. Canal paresis and symptoms side were not statistically correlated in caloric test.

Risk factors for ischemic stroke and stroke subtypes in patients with chronic kidney disease

GÜLER Siber, NAKUS Engin, UTKU Ufuk

Background - The aim of this study was to compare ischemic stroke subtypes with the effects of risk factors, the relationship between grades of kidney disease and the severity of stroke subtypes. Methods - The current study was designed retrospectively and performed with data of patients who were hospitalised due to ischemic stroke. We included 198 subjects who were diagnosed with ischemic stroke of Grade 3 and above with chronic kidney disease. Results - In our study were reported advanced age, coronary artery disease, moderate kidney disease as the most frequent risk factors for cardioembolic etiology. Hypertension, hyperlipidemia, smoking and alcohol consumption were the most frequent risk factors for large-artery disease. Female sex and anaemia were the most frequent risk factors for small-vessel disease. Dialysis and severe kidney disease were the most frequent risk factors in unknown etiologies, while male sex, diabetes mellitus, prior stroke and mild kidney disease were the most frequent risk factors for other etiologies. National Institute of Health Stroke Scale (NIHSS) scores were lower for small-vessel disease compared with other etiologies. This relation was statistically significant (p=0.002). Conclusion - In order to improve the prognosis in ischemic stroke with chronic kidney disease, the risk factors have to be recognised and the treatment options must be modified according to those risk factors.

[The applicability of 123I-FP-CIT SPECT dopamine transporter imaging in clinical practice]

PERLAKI Gábor, SZEKERES Sarolta, JANSZKY József, DEZSŐ Dániel, ASCHERMANN Zsuzsanna, ZÁMBÓ Katalin, KOVÁCS Norbert

[The 123I-FP-CIT dopamine transporter SPECT imaging is a sensitive method to assess functional dopaminergic neuron terminals in the striatum. The method has also been available in Hungary for years. There are two main indications: (i) to help differentiate essential tremor from clinically uncertain Parkinsonism, including patients with early symptoms and (ii) to help differentiate dementia with Lewy bodies from Alzheimer’s disease. The aim of this paper is to review 123I-FP-CIT SPECT imaging based on international data/guidelines and our own experiences, thereby assisting nuclear medicine practitioners and neurologists.]

The effect of psychiatric comorbidities and stress-coping strategies on perceived quality of life in migraine

PETROVICS-BALOG Anna, MAJLÁTH Zsófia, LUKÁCS Melinda, HOLCZER Adrienn, MUST Anita, TAJTI János, VÉCSEI László

Purpose – Migraine is one of the most disabling primary headache conditions. We aimed to detect hidden symptoms of anxiety and depression and to survey stress-coping mechanisms and related quality of life in a large migraine population without any known psychiatric comorbidity. Method – 123 migraine patients (MG) and 66 healthy subjects (HC) completed the Beck Depression Inventory-II (BDI-II), the State and Trait Anxiety Inventory (S-STAI and T-STAI), the Stress and Coping Inventory (SCI) and the 36-Item Short Form Health Survey (SF-36). Results – MG patients reached significantly higher scores on the BDI-II and the T-STAI yielding previously undetected anxiety and depression symptoms. Significant differences were present on the SCI: higher stress scores and lower coping levels suggested impaired stress-coping strategies in migraine. MG patients achieved significantly lower scores on most of SF-36 subscales indicating lower perceived quality of life. Significant correlations were found between BDI-II, T-STAI, SCI scores and subscales of the SF-36. Conclusion – Unrecognized symptoms of anxiety and depression, as well as less effective stress-coping strategies might be related to the lower perceived quality of life in migraine. The screening of these symptoms might lead to more focused and efficient therapeutic strategies. Addressing stress management techniques could improve quality of life on the long-term.

[Tracing trace elements in mental functions]

JANKA Zoltán

[Trace elements are found in the living organism in small (trace) amounts and are mainly essential for living functions. Essential trace elements are in humans the chromium (Cr), cobalt (Co), copper (Cu), fluorine (F), iodine (I), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se), zinc (Zn), and questionably the boron (B) and vanadium (V). According to the biopsychosocial concept, mental functions have biological underpinnings, therefore the impairment of certain neurochemical processes due to shortage of trace elements may have mental consequences. Scientific investigations indicate the putative role of trace element deficiency in psychiatric disorders such in depression (Zn, Cr, Se, Fe, Co, I), premenstrual dysphoria (Cr), schizophrenia (Zn, Se), cognitive deterioration/de­mentia (B, Zn, Fe, Mn, Co, V), mental retardation (I, Mo, Cu), binge-eating (Cr), autism (Zn, Mn, Cu, Co) and attention deficit hyperactivity disorder (Fe). At the same time, the excess quantity (chronic exposure, genetic error) of certain trace elements (Cu, Mn, Co, Cr, Fe, V) can also lead to mental disturbances (depression, anxiety, psychosis, cognitive dysfunction, insomnia). Lithium (Li), being efficacious in the treatment of bipolar mood disorder, is not declared officially as a trace element. Due to nutrition (drinking water, food) the serum Li level is about a thousand times less than that used in therapy. However, Li level in the red cells is lower as the membrane sodium-Li countertransport results in a Li efflux. Nevertheless, the possibility that Li is a trace element has emerged as studies indicate its potential efficacy in such a low concentration, since certain geographic regions show an inverse correlation between the Li level of drinking water and the suicide rate in that area. ]

Hyperhomocysteinemia in female migraineurs of childbearing ages

ALEMDAR Murat, SELEKLER Macit Hamit

Background and purpose - Migraine is a risk factor for ischemic stroke in women of childbearing ages. Previous researches revealed a higher prevalence of hyperhomocysteinemia in migraineurs. Possible differences on the frequencies of hyperhomocysteinemia between migraine with aura and migraine without aura could contribute the established variances in stroke risk between these migraine types. Therefore, we aimed to search if the frequency of hyperhomocysteinemia was different between these subtypes of migraine or not. Methods - We analyzed the findings of serum homocysteine levels in female migraineurs of 16-49 years old who admitted to our outpatient clinic. Results - Homocysteine level was elevated in 13.3% of study population. There were not any significant differences on median serum homocysteine levels between migraine with aura (8.0 mikromol/L) and without aura (8.5 mikromol/L). (p=0.426) The frequencies of hyperhomocysteinemia were also similar (9.1% versus 16.7%, respectively; p=0.373). Correlation analyses did not reveal any linear correlation between ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura (p=0.417 and p=0.647, respectively). Similarly, any linear correlation between disease ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura was not detected (p=0.359 and p=0.849, respectively). Conclusion - The median serum homocysteine levels and the frequencies of hyperhomocysteinemia are similar between migraine with aura and without aura in women of childbearing ages. Therefore, the variances on stroke risk ratios between these types of migraine are probably not originated from the differences of serum homocysteine status.

[The Importance of Teamwork and Patient Education in the Rehabilitation of Stroke Patients]

HORVÁTH Orsolya, STERLIK Krisztina

[The aim of the study: Stroke is an increasing problem in public health. Every year in Hungary tens of thousands of people survive stroke and continue their life bearing all the negative consequences of this disease. Well organized and early rehabilitation treatment, based on the patients’ clinical condition, improves not only their life expectancy, but also quality of life and helps to restore the self- sufficient living as well. The majority of the stroke patients live with numerous of cerebrovascular risk factors, highlighting the special importance of personalized education to prevent the recurrent stroke. Material and Methods: The aim of our investigation was to examine the efficiency of the neuro-rehabilitation teamwork and personalized patient-education among stroke patients took part inpatient rehabilitation of the Teaching Hospital and Rehabilitation Center of Sopron (2016-2017). We measured the change in ability of self- sufficient living with the FIM scale and the Bartel index, while we analyzed the presence of the modifiable cerebrovascular risk-factors with the assistance of a questionnaire was completed by the patient or the relatives (2016-2017). Results: During our research we also evaluated the knowledge of patients about their condition. According to our results the modifiable risk-factors occured cumulatively among our patients and despite the education that stroke patients received during the acute period in the hospital, there still occured a general lack of knowledge regarding their disease. Conclusions: Based on our results the complex rehabilitation therapy started at its earliest possible following the acute period was the most successful method of treatment. During the acute period, the dissemination of written educational materials and information sheets help the recovery phase until the start of the complex rehabilitation therapy. ]

[Neuroprotection in brain ischemia - doubts and hopes]

ZÁDOR Zsolt, BENYÓ Zoltán, LACZA Zsombor, HORTOBÁGYI Tibor, HARKÁNY Tibor

[In ischaemic stroke the two major potential therapeutic strategies are aimed at either improving cerebral blood flow or directly interacting with the cytotoxic cascade - a large body of evidence gained from animal studies is in support of them. In clinical trials direct neuroprotection by blocking the neurotoxic cascade remained ineffective, although there are several clinical trials still in progress. We summarize the experimental data and present the results of clinical trials and also discuss why so many drugs, which were effective in animal studies, failed in human trials. It is emphasized, that 1. in most animal studies the reduction of infarct size, i.e. the amount of saved penumbral tissue, was the outcome measure, whereas neurological function remained unassessed; 2. the recovery of intellectual performance and higher cortical functions are of major importance in the future quality of life in stroke victims; however, it is impossible to examine these parameters appropriately in animal studies; 3. in many clinical trials the patient population was rather heterogenous and low in number, the study protocol was not optimal and the critical analysis of the subacute and chronic phase was lacking or insufficient. We present the major experimental stroke models, discuss their similarities, differencies and limitations as compared to the human pathophysiological processes. The pitfalls of extrapolating data from animal studies to clinical practice are also summarized. The complex network of functional and morphological intercellular connections, the long timescale of neurotoxic and reparative events and the lessons learned from clinical trials suggest, that the use of drug combinations (therapeutic cocktails) targeting multiple steps of the neurotoxic cascade would hopefully result in more effective treatment of ischaemic stroke. Strategies to facilitate brain plasticity and regeneration is an additional promising tool to enhance recovery in brain ischaemia.]

[EPIDEMIOLOGY OF STROKE IN THE ELDERLY]

POZSEGOVITS Krisztián, KAZUO Suzuki, NAGY Zoltán

[Background - In the industrialized countries the very elderly stroke patient is more frequent than before. For the time being Japanese people have the highest expected lifespan, so the epidemiological features of stroke in the very elderly can be examined here quite easily. From a few publications with low case number it is known that in this group of patients the statistical characteristics of stroke is remarkably different from the youngers' one. Subjects and methods - The subjects aged 85 or more years were selected from the Akita Stroke Registry with first-ever acute stroke from 1996 to 1998. Results - 8,046 cases were recorded. There were 7362 patients aged <85 years, and 684 patients aged ≥85 years (8.5%). Sex ratio (women/men) was 1.89 in the two age groups. In the population of Akita the crude incidence of firstever stroke was 222/100,000/year, and 1,085/100,000/year in the very elderly, who were characterized with relatively lower prevalence of stroke risk factors, except that of atrial fibrillation (26.9%) and cardiac diseases (34.2%). The stroke subtype distribution (cerebral infarction 73.2%, intracerebral haemorrhage 20.6%, subarachnoidal haemorrhage 6.1%) was significantly different from the one known in Japan. Mortality rates were considerably high, especially in the SAH group. The most powerful prognostic factor of death was the consciousness level at onset. The following in order of predicting value was the SAH stroke subtype. Conclusion - While people aged 85 years or more had relatively lower prevalence of cardiovascular risk factors, they suffered stroke with very high frequency, the evolved cerebrovascular event caused very severe symptoms and led to death with high rate. Implicitly this is illuminating the complexity of aging as a procession, furthermore it raises the importance of prevention, more rather of the acute stroke care and rehabilitation in this high age group.]

[THE SIGNIFICANCE OF CHLAMYDIA PNEUMONIAE IN SELECTED NEUROLOGIC DISORDERS]

HORVÁTH Zoltán, VÉCSEI László

[Chlamydia pneumoniae has recently been implicated in the pathogenesis of several neurological diseases. As an intracellular parasite with its unusual life cycle it is able to circumvent the immune system and to persist in the organism. It has the ability to modify the function of the infected cell and supposedly induce autoimmune reactions. These properties can make it pathogenic in several chronic neurological diseases including multiple sclerosis, atherosclerosis, stroke, Alzheimer dementia and giant cell arteriitis. The evaluation of the available, often contradictory, data that are based on various different methods is not easy. The importance of the issue is enhanced by the potential need for antibiotic treatment.]
