[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.]

[PERSISTENT AKINETIC-RIGID SIDE EFFECTS OF NEUROLEPTICS MAY INDICATE WILSON'S DISEASE]

ASCHERMANN Zsuzsanna, SZALAY Ferenc, SCHMIDT Erzsébet, KOMOLY Sámuel, ILLÉS Zsolt

[Here we report two cases, where neuroleptic treatment provoked persistent akinetic-rigid symptoms resulting in the diagnosis of Wilson's disease. No liver function abnormalities suggested Wilson's disease in one of the cases. In both cases, the akinetic-rigid symptoms were originally attributed to side effects of neuroleptics, but symptoms persisted after discontinuation of treatment. In one of the cases, T2-weighted cranial MRI indicated bilateral hyperintense signals in the basal ganglia. Our cases suggest that in a subgroup of Wilson's disease, dopamin receptor antagonists may provoke akinetic-rigid neurological symptoms possibly due to the damage of dopaminergic neurons. Persistent akinetic-rigid side effects of neuroleptics in young patients thus require diagnostic tests to exclude Wilson's disease even in unsuspected cases.]

[ANIMAL MODELS OF CEREBRAL ISCHEMIA - TESTING THERAPEUTIC STRATEGIES IN VIVO]

ERDŐ Franciska, KONSTANTIN-ALEXANDER Hossmann

[Acute cerebral ischemia is one of the leading causes of mortality and chronic disability worldwide. Animal models of focal (stroke-type) and global (cardiac arrest-type) ischemia have been established to investigate the morphological, functional and molecular consequences and to design therapeutic strategies for the improvement of ischemic injury. Despite highly beneficial effects in experimental studies, most human clinical trials were disappointing, suggesting inefficacies in the design and/or translation of animal experiments. In this review the pathophysiologically relevant particularities of ischemia models will be discussed to provide a rational basis for the proper selection of animal models for testing therapeutic strategies under experimental conditions.]

[SIMULTANEOUS CENTRAL AND PERIPHERAL NERVOUS SYSTEM INVOLVEMENT IN SYSTEMIC LUPUS ERYTHEMATOSUS]

ILNICZKY Sándor, KAMONDI Anita, ARÁNYI Zsuzsanna, VÁRALLYAY György, GAAL Barbara, SZIRMAI Imre, NAGY György

[Systemic lupus erythematosus is a frequent autoimmune disease, affecting several organs, including the brain, spinal cord and nerves. Cerebral vasculitis, transverse myelitis and polyneuropathy are the most common neurological manifestations. We report a case of a 46 years old woman who suffered incomplete transverse myelitis in her age of 44. After 2 years the second relapse presented with arthralgias, painful paraesthesias and weakness of the lower limbs. Neurological signs suggested involvement of the central and the peripheral nervous system. Based upon clinical and laboratory findings systemic lupus erythematosus was diagnosed. Magnetic resonance imaging revealed two hyperintense lesions on T2 weighted scans within the cervical spinal cord. The brain scan was normal. Protein content was slightly elevated in the cerebrospinal fluid, with normal cell count. Electrophysiological examinations diagnosed a subacute sensory-motor axonal polyneuropathy. On methylprednisolone treatment her condition improved. Simultaneous development of central and peripheral lesions of the nervous system in cases with systemic lupus erythematosus may lead to a challenge to establish the diagnosis.]
