[Affective and cognitive decision making in major depression: influence of the prefrontal cortex, serotonin transporter genotype and personality traits]

MUST Anita, HORVÁTH Szatmár, JANKA Zoltán

[Patients with major depressive disorder (MDD) show neuropsychological impairments, including deficient executive functions and suboptimal decision-making strategies, which are mediated by several brain regions. In the development of these symptoms the pathology of the prefrontal cortex (PFC), including the dorsolateral, ventromedial and orbitofrontal regions, may also play an important role. Neuropsychological assessment is a useful tool in detecting and measuring these deficiencies, showing that patients with MDD exhibit altered sensitivity to reward and punishment. However, impairment of emotional decisionmaking strategies in MDD is influenced by genetic variations (5-HTTLPR polymorphism) and personality traits, which seem to have a higher predictive value on decision making performance than the clinical symptoms.]

Matrix metalloproteinases and their tissue inhibitors in relapsing remitting multiple sclerosis: Possible markers and treatment agents

SANLI Arzu, OZTURK Musa, SOYSAL Aysun, DOVENTAS Yasemin, BASOGLU Fulya, GOZUBATIK-CELIK R. Gokcen, BAYBAS Sevim

Matrix metalloproteinases (MMPs), which are synthesized by many cell groups and responsible for the destruction of matrix proteins, and endogen tissue inhibitors of MMPs (TIMPs) have a role in the pathogenesis of Multiple Sclerosis (MS) by affecting the blood-brain barrier. We aimed to investigate the role of MMPs and TIMPs in the immunopathogenesis and in the course of multiple sclerosis (MS). We enrolled 25 relapsing remitting MS patients, who had a definite MS diagnosis according to McDonald criteria and 25 healthy subjects similar for age and gender as control group. MMP-9- and TIMP-1 levels were measured twice in patient group (one time during an attack and one in remission) and once in healthy subjects. MMP-9- and TIMP-levels of patients during attack and remission period and MMP-9/TIMP-1 ratio were found significantly higher than in the control subjects. In patient group MMP-9 and TIMP-1 levels and MMP-9/TIMP-1 ratio during attacks were not significantly different than during remission period. However, when subdivided according to their number of attacks, patients with 2 attacks had significantly higher levels during attack period comparing to remission period (p<0.05); in case of patients with more than 2 attacks did not have a statistically significant difference in attack and remission periods. Matrix metalloproteinases are important actors in MS immunopathogenesis, particularly in the early period and inhibitor agents for these enzymes can be used as a treatment option.

[Covid-19 associated neurological disorders]

SZÔTS Mónika, PÉTERFI Anna, GERÖLY Júlia, NAGY Ferenc

[The clinical signs of SARS-CoV-2 infection has become more recognisable in recent times. In addition to common symptoms such as fever, cough, dyspnea, pneumonia and ageusia, less common complications can be identified, including many neurological manifestations. In this paper, we discuss three Covid-19 associated neurological disorders (Case 1: Covid-19 encephalitis, Case 2: Covid-19 organic headache, Case 3: SARS-CoV-2-infection and ischaemic stroke). We emphasize in our multiple case study that during the present pandemic, it is especially important for neurologists to be aware of the nervous system complications of the virus infection, thus saving unnecessary examinations and reducing the frequency of patients’ contact with health care personnel. ]

[Family planning in multiple sclerosis: conception, pregnancy, breastfeeding]

RÓZSA Csilla

[Family planning is an exceptionally important question in multiple sclerosis, as women of childbearing age are the ones most often affected. Although it is proven that pregnancy does not worsen the long-term prognosis of relapsing-remitting multiple sclerosis, many patients are still doubtful about having children. This question is further complicated by the fact that patients – and often even doctors – are not sufficiently informed about how the ever-increasing number of available disease-modifying treatments affect pregnancies. Breastfeeding is an even less clear topic. Patients usually look to their neurologists first for answers concerning these matters. It falls to the neurologist to rationally evaluate the risks and benefits of contraception, pregnancy, assisted reproduction, childbirth, breastfeeding and disease modifying treatments, to inform patients about these, and then together come to a decision about the best possible therapeutic approach, taking the patients’ individual family plans into consideration. Here we present a review of relevant literature adhering to international guidelines on the topics of conception, pregnancy and breastfeeding, with a special focus on the applicability of approved disease modifying treatments during pregnancy and breastfeeding. The goal of this article is to provide clinicians involved in the care of MS patients with up-to-date information that they can utilize in their day-to-day clinical practice. ]

[Tension type headache and its treatment possibilities]

ERTSEY Csaba, MAGYAR Máté, GYÜRE Tamás, BALOGH Eszter, BOZSIK György

[Tension type headache, the most common type of primary headaches, affects approximately 80% of the population. Mainly because of its high prevalence, the socio-economic consequences of tension type headache are significant. The pain in tension type headache is usually bilateral, mild to moderate, is of a pressing or tightening quality, and is not accompanied by other symptoms. Patients with frequent or daily occurrence of tension type headache may experience significant distress because of the condition. The two main therapeutic avenues of tension type headache are acute and prophylactic treatment. Simple or combined analgesics are the mainstay of acute treatment. Prophylactic treatment is needed in case of attacks that are frequent and/or difficult to treat. The first drugs of choice as preventatives of tension type headache are tricyclic antidepressants, with a special focus on amitriptyline, the efficacy of which having been documented in multiple double-blind, placebo-controlled studies. Among other antidepressants, the efficacy of mirtazapine and venlafaxine has been documented. There is weaker evidence about the efficacy of gabapentine, topiramate, and tizanidin. Non-pharmacological prophylactic methods of tension type headache with a documented efficacy include certain types of psychotherapy and acupuncture. ]

[Effective therapy in highly active pediatric multiple sclerosis ]

MERÔ Gabriella, MÓSER Judit, LIPTAI Zoltán, DIÓSZEGHY Péter, BESSENYEI Mónika, CSÉPÁNY Tünde

[Multiple sclerosis (MS) is typically a disease of young adults. Childhood MS can be defined in patients under 18 years of age, although some authors set the limit un­der the age of 16 formerly known as “early-onset multiple sclerosis” or “juvenile multiple sclerosis”, seen in 3-5% of all MS patients. Nowadays, owing to ever-evolving, better diagnostic tools and well-traced, strictly defined diagnostic criteria, childhood MS is showing an increasing incidence worldwide (0.05-2.85/100 000). MS is characterized by recurrent episodes of the central nervous system with demyelination separated in space and time. In childhood almost exclusively the relapsing-remitting (RR) type of MS occurs. Based on experience in adults, the goal in the pediatric population is also the early diagnosis, to initiate adequate DMT as soon as possible and to achieve symptom relief and good quality of life. Based on efficacy and safety studies in the adult population, inter­feron β-1a and glatiramer acetate were first approved by the FDA and EMA for the treatment of childhood MS also. The increased relapse rate and rapid progression of childhood MS and unfavorable therapeutic response to nearly 45% of the first DMT necessitated the testing of more effective and second-line drugs in the population under 18 years of age (PARADIGMS, CONNECT). Although natalizumab was reported to be effective and well-tolerated in highly active RRMS in childhood, evidence based studies were not yet available when our patients’ treatment started. In this article, we report on the successful treatment of three active RRMS patients with individually authorized off-label use of natalizumab.]
