Monopolar Depressive (DSMIII- R; MD) zeigten oft Leukoaraiose, Infarkte waren mit MD, Kontusionen und frühkindliche Schäden mit bipolarer Erkrankung assoziiert (BP; ANCOV A, p< .1). Kortikale Läsionen waren bei BP häufiger, jedoch fehlten signifikante Effekte von Läsionsort oder -zeitpunkt auf die Polarität der Erkrankung (ANOV A). Bei einigen Infarktpatienten kam es zur Verlaufsänderung (Chronifizierung, Bipolarität) nach Infarkt, alle Post-Infarkt-Ersterkrankungen waren bipolar. N2 - 46 patients with affective disorder and a pathologic CT scan were studied (infarct: 22, brain trauma: 6, leukoaraiosis: 11 , perinatal brain damage: 7). Unipolar depressives (DSM-I1I-R; MD) frequently had le ukoaraiosis, brain infarct was associated with unipolar depression , brain trauma and perinatal damage with bipolar illness (BP; ANCOV A , p < .1). Corticallesions were more frequ ent in BP, but ANOV A revealed no significant effect of lesion location and time of insu lt on illness polarity. In some patients with stroke course of illness changed (Ionger phases, bipolarity), first onset post-stroke went along with bipolar illness.

T1 - Hyperintense Marklagerläsionen bei psychiatrischen Patienten: räumliche Verteilung und psychopathologische Symptome T1 - Hyperintense white matter lesions in psychiatrie patients: spatial distribution and psychopathological symptoms N2 - In einem Kollektiv von 130 MR-tomographisch untersuchten psychiatrischen Patienten (axiale T2-SE-Sequenz) wurden Zahl und räumliche Verteilung von hyperintensen Marklagerläsionen ("white matter lesions"; WM L) erfaßt und die Ventricle-to-brain-Ratio (VBR) bestimmt. Eine Konfigurationsfrequenzanalyse auf der Grundlage der räumlichen WMLVerteilung erlaubte die Abgrenzung von vier Patientengruppen: 1. keine WML (n = 35), 2. WML rechts frontotemporal (n = 23), 3. WML bifrontal (n = 12), 4. WML ubiquitär (n = 16). Die während 3 Jahren beobachteten psychopathologischen Symptome dieser Patienten wurden retrospektiv nach dem AMDP-Systemdokumentiert. In der Gruppe mit ubiquitären WML überwogen organisch-psychopathologische Ttems, die VER war größer als in den anderen Gruppen (ANOVA;p < 0,001). Die räumliche W M L- Verteilung erklärte 10,24 % der Gesamtvarianz psychopathologischer M erkmalsverteilung in den Gruppen.

N2 - In a sampie of 130 patients who had undergone MRI (transverse TIweighted SE sequenee) patchywhite matter lesions (WML) were documented according to number and spatial distribution in the brain. Ventricle-to-Brain Ratio (VBR) was determined. Configural frequency analysis led to delineation of four patient groups on the basis of WML 10-cation: 1. no WML (n = 35), 2. right frontal-temporal WML (n = 23), 3. bifrontal WML (n = 12),4. WML in all/all but one brain region (n = 16). Psychopathological symptoms reported in the course of a maximum of 3 years were documen ted by chart review. In the 'pervasive WML' group psychopathological items characteristic of organic brain syndromes prevailed, mean VER exceeded values in all other groups (ANOVA, p < 0.001). WML spatial distribution accounted for 10.2 % oftotal psychopathological variance. Patient age, but not VER, had a significant impact on symptom profile (MANCOVA). When the 'pervasive WML' group was excluded, the finding of a significant effect of WML location on psychopathological symptom profiles was robust. Bifrontal WML were associated with thought incoherence, right frontal-temporal WML with affective symptoms. Findings support an impact of spatial distribution of unspecific WML on psychopathological symptoms in psychiatrie patients.

JF - BMC Psychiatry N2 - Background Genome wide association studies reported two single nucleotide polymorphisms in ANK3 (rs9804190 and rs10994336) as independent genetic risk factors for bipolar disorder. Another SNP in ANK3 (rs10761482) was associated with schizophrenia in a large European sample. Within the debate on common susceptibility genes for schizophrenia and bipolar disorder, we tried to investigate common findings by analyzing association of ANK3 with schizophrenia, bipolar disorder and unipolar depression. Methods We genotyped three single nucleotide polymorphisms (SNPs) in ANK3 (rs9804190, rs10994336, and rs10761482) in a case-control sample of German descent including 920 patients with schizophrenia, 400 with bipolar affective disorder, 220 patients with unipolar depression according to ICD 10 and 480 healthy controls. Sample was further differentiated according to Leonhard's classification featuring disease entities with specific combination of bipolar and psychotic syndromes. Results We found no association of rs9804190 and rs10994336 with bipolar disorder, unipolar depression or schizophrenia. In contrast to previous findings rs10761482 was associated with bipolar disorder (p = 0.015) but not with schizophrenia or unipolar depression. We observed no association with disease entities according to Leonhard's classification. Conclusion Our results support a specific genetic contribution of ANK3 to bipolar disorder though we failed to replicate findings for schizophrenia. We cannot confirm ANK3 as a common risk factor for different diseases.

Due to presence of imprinted genes within the region, the parental origin of these duplications may be key to the pathogenicity. Duplications of maternal origin are associated with disease, whereas the pathogenicity of paternal ones is unclear. To clarify the role of maternal and paternal duplications, we conducted the largest and most detailed study to date of parental origin of 15q11.2-q13.3 interstitial duplications in DD, ASD and SZ cohorts. We show, for the first time, that paternal duplications lead to an increased risk of developing DD/ASD/multiple congenital anomalies (MCA), but do not appear to increase risk for SZ. The importance of the epigenetic status of 15q11.2-q13.3 duplications was further underlined by analysis of a number of families, in which the duplication was paternally derived in the mother, who was unaffected, whereas her offspring, who inherited a maternally derived duplication, suffered from psychotic illness. Interestingly, the most consistent clinical characteristics of SZ patients with 15q11.2-q13.3 duplications were learning or developmental problems, found in 76% of carriers. Despite their lower pathogenicity, paternal duplications are less frequent in the general population with a general population prevalence of 0.0033% compared to 0.0069% for maternal duplications. This may be due to lower fecundity of male carriers and differential survival of embryos, something echoed in the findings that both types of duplications are de novo in just over 50% of cases. Isodicentric chromosome 15 (idic15) or interstitial triplications were not observed in SZ patients or in controls. Overall, this study refines the distinct roles of maternal and paternal interstitial duplications at 15q11.2-q13.3, underlining the critical importance of maternally expressed imprinted genes in the contribution of Copy Number Variants (CNVs) at this interval to the incidence of psychotic illness. This work will have tangible benefits for patients with 15q11.2-q13.3 duplications by aiding genetic counseling.

T1 - Triplet repeats in clinical subtypes of schizophrenia: variation at the DRPLA (B37 CAG repeat) locus is not associated with periodic catatonia N2 - Clinical evidence for a dominant mode of inheritance and anticipation in periodic catatonia, a distinct subtype of schizophrenia, indicates that genes with triplet repeat expansions or other unstable repetitive elements affecting gene expression may be involved in the etiology of this disorder. Because patients affected with dentatorubral-pallidoluysian atrophy (DRPLA) may present with "schizophrenic" symptoms, we have investigated the DRPLA (B 37 CAG repeat) locus on chromosome 12 in 41 patients with periodic catatonia. The B 37 CAG repeat locus was highly polymorphic but all alleles in both the patient and control group had repeat sizes within the normal range. We conclude that variation at the DRPLA locus is unlikely to be associated with periodic catatonia. The evidence for dominant inheritance and anticipation as well as the high prevalence of human brain genes containing trinucleotide repeats justifies further screening for triplet repeat expansions in periodic catatonia.

P300 amplitude is conventially assessed at midline electrodes (PZ), anti asymmetric topography as reported in schizophrenics, may conj'ound this measurement. We lnvestigated the possible Interaction between P300 ropography and assessments of amplitudes. ln 41 clinically stable schizophrenics and 31 normal controls, the generalfinding ofreduced amplitudes at the P'l electrode and topographical asymmetrles in the patient group were replicated. ln both groups, a.symmetries of the P300 field (lateralized peaks) reduced the standard amplitude assessment at the midline parletal electrode, but did not Qjfoct the reference-independent, global amplitude assessment. This shows thal asymmetry per se does not imply reduced field strength. in addition, in schizophreraics. but not in controls, there was a significcmt effect oftlae direction of asymmetry on both amplltude measures, amplitudes belng lower with increasing shift ofthe P300 peak to the right side. Considering also the slightly left-lateralized peaks in the normal controls. this suggests rhat only right lateralized P300 peaks upressfunctional deficits in schizophrenics, whereas left lateralized pealcs fall wlthin the physiological variability of the P3OO field. Tht refonnce-independent amplitude assessment is proposed for unambiguous amplitude assessment in order to better define the clinical, psychological and physiopathological mtaning of the P3OO alterations in schizophrenics.

Asymmetries in evoked potential P300 topography are still controversial because of inconsistent findings. In the present study. previous results of abnormal lateralization of P300 were replicated in stabilized residual Schizophrenie patients. Auditory P300 was recorded during an odd ball task in which subjeets detected rare target stimuli. Schizophrenie patients had the P300 peak shifted to the right hemisphere and differed signifieantly from age- and sex-matched normal control subjects who had left-lateralized P300 peaks. A comparison of different methods of assessment and analysis of the topographical features of the P300 electric fields showed that the extraction of reference-independent descriptors of P300 topography is a reliable and sensitive method for statistical handling of the maps. The results suggest left hemispheric dysfunction during cognitive tasks in a subgroup of Schizophrenie patients. Inconsistencies between previous sturlies are likely to be due to heterogeneous patient groups, which may have included patients in an acute Schizophrenie episode or patients in clinical remission. lnvestigation of the clinical meaning of P300 alterations requires careful psychopathological definition of the patient groups.

Im zweiten Trimenon waren gehäuft Infektionen aufgetreten. Zehn von 80 Müttern von Kontrollpersonen erinnerten ebenfalls eine Infektion. Im Vergleich zu den Kontrollen halfen Mütter Schizophrener im 5. Schwangerschaftsmonat häufiger Infektionen als in den anderen Gestationsmonaten (p < 0,05). Bei "familiären" und "sporadischen" Schizophrenen gemäß DSM III-R kamen im Vergleich zu Kontrollen Infektionen in gleicher Häufigkeit vor. Wurden hingegen in der Diagnostik schizophrener Psychosen die Definitionen von Leonhard zugrunde gelegt, ergaben sich signifikante Unterschiede! Bei den systematischen Schizophrenen (denen nach Leonhard keine erbliche Disposition zugrunde liegt) waren Infektionen gehäuft im 2. Schwangerschaftsdrittel aufgetreten, sowohl im Vergleich zu Kontrollen (p < 0,01) als auch im Vergleich zu den unsystematischen Schizophrenen, die hauptsächlich genetisch bedingt zu sein scheinen (p < 0,001). Infektionserkrankungen im 5. Schwangerschaftsmonat waren ausschließlich bei den Müttern von systematischen Schizophrenen vorgekommen. Bei diesen Krankheitsformen scheinen Infektionen im 2.

N2 - In a retrospective study, 16 of 80 mothers of chronic DSM III-R schizophrenics reported having had a serious infectious disease during pregnancy. Eleven of the infections had occurred during the second trimester. Influenza and the common cold with fever were frequent. Ten of 80 female controls also recalled having had an infectious illness during pregnancy. Compared to the controls, mothers of schizophrenics reported more infectious illness during pregnancy, particularly during the fifth month ofgestation (p < 0.05). Mothers of familial and of sporadic DSM III-R schizophrenics reported equal frequencies of infections in pregnancy. In contrast, when Leonhard's classification of psychoses was applied, significant differences appeared. Infections during pregnancy were scarcely found in unsystematic schizophrenics (mainly genetically determined according to Leonhard). In systematicschizophrenics (mainly exogenously determined according to Leonhard), a significantly higher frequency of infectious diseases was reported for the second trimester as compared both to controls (p < 0.01) and to unsystematic schizophrenics (p < 0.001). Infections during the fifth month of gestation were exclusively reported in systematic schizophrenics. Thus, in the systematic forms of schizophrenia infections during the second trimester and particularly during the fifth montb ofgestation seem to play an important role in the etiology and seem to be of causal importance for the various cytoarchitectural abnormalities detected in the central nervous system of schizophrenics.

The Lewis & Murray and Fuchs scales were used for evaluation. In both scales, unsystematic schizophrenias did not differ from controls, but those with OCs were significantly (p < 0.01) earlier hospitalized (20.5 years) than those without OCs (25.6 years). Systematic schizophrenics had an increased frequency, severity and total score of OCs compared to controls in the Fuchs scale (p < 0.0 I). Likewise, in the Lewis & Murray scale systematic schizophrenia showed an increased presence ofOCs compared to controls (p < 0.05) and to unsystematic schizophrenia (p < 0.1 ). Systematic schizophrenias were significantly allocated to matemal infectious diseases during mid-gestation. Patients with matemal infections showed moreadditional OCs than those without (p < 0.05; Lewis & Murray scale). In systematic schizophrenia, a history of OC was not associated with an early onset of the disease. In the genetic determined schizophrenias prenatal and perinatal disturbanccs Iead to an early onset of the disease, however, in systematic schizophrenias they seem to be of causal importance for the development of the disease.

Zur Auswertung wurden die Skalen von Lewis & Murray sowie von Fuchs verwandt. Unsystematische Schizophrenien unterschieden sich in beiden Skalen nicht von den Kontrollen. Diejenigen mit Komplikationen wurden jedoch signifikant früher als diejenigen ohne Komplikationen ersthospitalisiert (p < 0,01 ). Bei systematischen Schizophrenen waren in ; der Skala von Fuchs Häufigkeit, Schweregrad sowie der Summenwert der Komplikationen gegenüber den Kontrollen erhöht (p < 0,0 I).

Systematische Schizophrenien waren auch assoziiert mit Schwangerschaftsinfektionen im zweiten Trimenon. Mütter mit Schwangerschaftsinfektionen zeigten gehäuft weitere perinatala Komplikationen (p < 0,05). Geburtskomplikationen hatten bei systematischen Schizophrenen jedoch keinen Einfluß auf den Zeitpunkt des Krankheitsbeginns. Während pdi und perinatale Störungen bei genetisch determinierten Schizophrenien lediglich einen frühen Krankheitsbeginn bewirken, scheinen sie bei den systematischen Schizophrenien von ursächlicher Bedeutung fiir die Krankheitsentstehung zu sein.

Different psychiatrie diagnostic systems were compared. Infections were reported by the mothers of familial and sporadic DSM I1I-R schizophrenics in equal proportion. However, applying Leonhard's classification, the frequency of infections was found to be significantly increased in 'systematic' schizophrenia (mainly exogenously induced in the view of Leonhard) compared to 'unsystematic' schizophrenia (mainly genetically determined according to Leonhard's findings). Most of the infections occurred during the second trimester (nine out of 13). Thus, in the 'systematic' forms of schizophrenia (low genetic loading), maternal infections in this crucial period of neurodevelopment would appear to be important causative factors in the cytoarchitectural deviance detected in the central nervous system of schizophrenics.

N2 - Three ease reports will be used to describe the self-torturing depression, one form of Leonhard's monopolar depressive disorders. The main symptomatology consists of marked feelings of guilt, as weil as ideas of self-abasement and self-depreciation. The severe anxious-depressive affect developes on the grounds of these symptoms. Worries of the patients about their family are also characteristic. Excessive self-reproach results in the expectation of and demand for heaviest punishment. These symptoms repeatedly occur during each episode. Other depressive symptoms like inhibited thinking and motor retardation are lacking. The course of the disease is strictly monopolar. In Leonhard's original description the mean duration of the episodes was found to be 5.8 months. We noticed a mean duration of 25 episodes of 4.1 months. The clinical manifestation of the episodes can only insignificantly be influenced by modern therapy. There is little evidence for familial loading with affective psychoses.

In this study, out of a sample of 100 patients with psychotic disorders, 80 were investigated by array for the presence of CNVs. The assessment of the severity of psychiatric symptoms was performed using standardized instruments and ICD-10 was applied for diagnostic classification. In three patients, a submicroscopic CNV was demonstrated, one with a loss in 1q21.1 and two with a gain in 1p13.3 and 7q11.2, respectively. The association between these or other CNVs and schizophrenia or schizophrenia-like psychoses and their clinical implications still remain equivocal. While the CNV affected genes may enhance the vulnerability for psychiatric disorders via effects on neuronal architecture, these insights have not resulted in major changes in clinical practice as yet. Therefore, genome-wide array analysis should presently be restricted to those patients in whom psychotic symptoms are paired with other signs, particularly dysmorphisms and intellectual impairment.

T1 - Cycloid psychoses: Leonhard's descriptions revisited JF - European Journal of Psychiatry N2 - Background and Objectives: Cycloid psychoses are characterized by polymorphic symptomatology with intraphasic bipolarity, a remitting and recurrent course and favourable prognosis. Perris and Brocicington (P&B) described the first set of operational criteria that were partly incorporated in ICD-10. The present study investigates psychopathological profiles according to the P&B criteria and the original descriptions by Leonhard, both against the background of the criteria from the prevailing international classification systems. Methods: Eighty patients with psychotic disorders were recruited and assessed with various psychometric instruments at baseline and after six weeks of antipsychotic treatment in order to investigate the presence of cycloid psychoses according to Leonhard (LCP) and the effect of treatment with antipsychotics. The overlap between LCP and DSM-IV Brief Psychotic Disorder (BPD), ICD Acute Polymorphic Psychotic Disorder (APP) and P&B criteria was calculated. Results: Using P&B criteria and a symptom checklist adapted from the original descriptions by Leonhard, 14 and 12 cases of cycloid psychosis were identified respectively reflecting a prevalence of 15-18%. Small though significant concordance rates were found between LCP and both DSM-BPD and ICD-APP. Concordance between LCP and P&B criteria was also significant, but modest. Conclusions: This study demonstrates that LCP can be identified in a substantial number of patients with psychotic disorders. Cycloid psychoses are not adequately covered in current classification systems and criteria. Since they are demonstrated to have a specific psychopathological profile, relapsing course and favourable prognosis, it is advocated to include these psychoses in daily differential diagnostic procedures.

As to schizophrenia, research into the pathophysiology has focused on dopamine, brain-derived neurotrophic factor, and glutamate signaling in which, concerning the latter, the N-methyl-d-aspartate receptor plays a crucial role. The present study aims to determine whether CP can biochemically be delineated from schizophrenia. Eighty patients referred for psychotic disorders were assessed with the Comprehensive Assessment of Symptoms and History, and (both at inclusion and after 6 weeks of antipsychotic treatment) with the Positive and Negative Syndrome Scale and Clinical Global Impression. From 58 completers, 33 patients were diagnosed with schizophrenia and ten with CP according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, and Leonhard criteria, respectively. Fifteen patients were diagnosed with other disorders within the psychosis spectrum. At both time points, blood levels of the dopamine metabolite homovanillic acid, brain-derived neurotrophic factor, and amino acids related to glutamate neurotransmission were measured and compared with a matched control sample. Patients with CP showed a significantly better response to antipsychotic treatment as compared to patients with schizophrenia. In CP, glycine levels were elevated and tryptophan levels were lowered as compared to schizophrenia. Glutamate levels were increased in both patient groups as compared to controls. These results, showing marked differences in both treatment outcome and glutamate-related variable parameters, may point at better neuroplasticity in CP, necessitating demarcation of this subgroup within the psychosis spectrum.
