[The aim of this paper is to give a short introduction to the so called ipseity-hyperreflexivity model of schizophrenia in light of the philosophical thesis of minimal self-consciousness. According to the notion of minimal self-consciousness there is no experience without the self-reference to the experiential subject. Dan Zahavi and Uriah Kriegel argue that minimal self-consciousness, including the sense of ownership of our experiences, remains intact in pathological cases as well. Contemporary phenomenological psychiatry, however, gives such an account of experiences that casts doubt on the invulnerability of ownership and rewrites the topography of self-consciousness. The investigation of minimal self-consciousness could open up new vistas regarding the interdisciplinary cooperation of philosophy and clinical sciences. ]

Evidence suggests that pathogen-associated pattern recognition receptors (Toll-like receptors, TLRs) are implicated in the pathophysiology of schizophrenia. TLRs are important in both peripheral immune responses and neuronal plasticity. However, the relationship between peripheral TLR expression and regional brain volumes is unknown in schizophrenia. We therefore assessed 30 drug-naïve, first-episode patients with schizophrenia. TLR4+/TLR1+ monocytes were measured using flow-cytometry. High resolution magnetic resonance images (T1 MRI) were obtained and analyzed with FreeSurfer. Results revealed significant negative correlations between the percentage of TLR4+ monocytes, mean fluorescent intensities, and brain volumes in frontal and anterior cingulate regions. The measures of TLR1+ monocytes did not show significant relationships with regional brain volumes. These results raise the possibility that abnormal TLR-activation is associated with decreased brain volumes in schizophrenia.
Clinical Neuroscience
Objective - To compare the intensity and the profile of psychotic symptoms and the characteristics of parental bonding of male schizophrenia patients with a history of homicide and those without a history of violent behaviour. Clinical question - We hypothesized more intense psychotic symptoms, especially positive symptoms as signs of a more severe psychopathology in the background of homicidal behaviour. We also hypothesized a more negatively perceived pattern (less Care more Overprotection) of parental bonding in the case of homicidal schizophrenia patients than in non-violent patients and non-violent healthy controls. Method and subjects - Symptom severity and symptom profiles were assessed with the Positive and Negative Syndrome Scale in a group of male schizophrenia patients (n=22) with the history of committed or attempted homicide, and another group (n=19) of male schizophrenia patients without a history of violent behaviour. Care- and Overprotection were assessed using the Parental Bonding Instrument (PBI) in a third group of non-violent healthy controls (n=20), too. Results - Positive, negative and general psychopathology symptoms in the homicidal schizophrenia group were significantly (p<0.005) more severe than in the non-violent schizophrenia group. Non-violent schizophrenia patients scored lower on Care and higher on Overprotection than violent patients and healthy controls. Homicidal schizophrenia patients showed a pattern similar to the one in the healthy control group. Conclusions - It seems imperative to register intense positive psychotic symptoms as predictive markers for later violent behaviour. In the subgroup of male homicidal schizophrenia patients negatively experienced parental bonding does not appear to be major contributing factor to later homicidal behaviour.

[Introduction - The purpose of our study was to find out whether the Hungarian adaptation of the RBANS (Repeatable Battery for the Assessment of Neuropsychological Status), a brief neurocognitive screening test, is appropriate for the differentation of healthy and non-healthy subject groups, or for the detection of differences between the cognitive performance of patient groups. Patients and method - The test battery was administrated to 38 healthy subjects, 69 schizophrenic patients, and 18 patients suffering from dementia (10 probable Alzheimer-type and eight vascular dementia). Results - There was a significant decrease of performance in all patient groups compared to the healthy group. In the schizophrenic group, the test indicated a deterioration of functioning in all cognitive areas. The patient group with Alzheimer-type dementia performed only slightly better than the schizophrenic group, because the fall of performance was not significant only one of the cognitive areas (in the visuo-spatial tasks) when compared to the healthy group. There was no difference between the performance of patients with vascular dementia and that of healthy subjects in direct memory, verbal and visuo-spatial tasks. The test results indicated an even deterioration of cognitive areas in patients with Alzheimer-type dementia. As for the vascular dementia group, the most vulnerable area proved to be that of attention, while their verbal functions were relatively spared. The deterioration in other cognitive functions shown by schizophrenic subjects was more moderate, but still significant. A comparison of the RBANS scores of the schizophrenic patients in our study and the result of an American study was also carried out. The global indeces showed no difference; only the pattern of the sub-scales was a little different. Conclusion - The Hungarian version of the RBANS seems appropriate for the differentiation of healthy and deteriorated cognitive performance in a Hungarian patient population.]

[In this paper, our aim is to scrutinise the psychology and phenomenology of interpersonal relationships from an interdisciplinary viewpoint. This multi-perspectival examination has a key concept: we critically discuss the interdisciplinary dialogues and philosophical appraisals regarding the issue of mirror neurons. Empathy and resonance phenomena have philosophical, psychological, and biomedical importance. Our paper, by applying certain philosophical and empirical results of the overarching paradigm of embodiment, attempts to shed light on several semantic problems, which could come up with respect to the function of mirror-neurons. In conclusion, we would like to attempt to utilise the results of contemporary phenomenology in order to clear some semantic problems, considering the features of mirroring and resonant behaviour.]

[More than 60 years old is the first antipschychotic drug that is operating atypically as well. With its multifarious history it gained the golden standard title of all therapy resistent schisophrenic cases for the last three decades. In this article we place clozapine on the map of psychopharmacology and review its history’s most important chapters. In the third part we discuss some of the most relevant effects and side effects of clozapine in the light of latest research and practical considerations touching the problem of the optimal start timing. ]
