    Notes: Summary Systematic CT studies on ten patients with persistent ischemic cerebral infarct revealed a constant phenomenon, the fogging effect. The hypodense infarct at the beginning will be isodense, or close to isodense, on the plain CT during the second or third weeks and at a later stage will be hypodense again. The fogging infarcted area shows homogeneous intensive contrast enhancement. Knowledge of the fogging effect is important for correct interpretation of the CT image and the indication for contrast medium CT. CT without contrast medium may lead to misinterpretation during the second and third weeks after the onset of cerebral infarction.

    Description / Table of Contents: Zusammenfassung Computertomographische Untersuchungen von Parkinsonkranken haben in einem hohen Prozentsatz Zeichen einer Hirnatrophie ergeben, in den meisten Fällen eine Kombination von kortikaler Atrophie und Ventrikelerweiterung. In der vorliegenden Untersuchung wurde den Beziehungen zwischen Hirnatrophie und körperlichen Befunden, die eine Arteriosklerose anzeigen oder deren Entstehung begünstigen, wie Übergewicht, EKG-Veränderungen, Hypertonie, Verkalkungen der A. carotis interna und der Aorta sowie einer Aortenlongation nachgeganen. Die Untersuchung basiert auf 173 behandelten und unbehandelten Parkinsonkranken (89 Männer, 84 Frauen) im Alter von 37–84 Jahren (mittleres Alter 64,6 J.), bei denen eine Computertomographie nach durchschnittlich 5,4 Jahren Krankheitsdauer durchgeführt wurde. Die Ergebnisse zeigen einen Anstieg sowohl von pathologischen CT-Befunden als auch von Verkalkungen im Carotissiphon mit zunehmendem Alter. Zwischen den übrigen Merkmalen und dem Alter bestehen keine Zusammenhänge. Die weitere Analyse ergab eine statistisch relevante Beziehung lediglich zwischen Hirnatrophie und Karotissiphonverkalkungen, insbesondere solchen der Media. Da sowohl die hirnatrophischen Veränderungen als auch die Verkalkungen des Karotissiphons mit höherem Lebensalter korreliert sind, während alle übrigen Merkmale, die als Zeichen einer Arteriosklerose angesehen werden können, keine eindeutigen Beziehungen zum Ausmß hirnatrophischer Veränderungen zeigen, ist zu folgern, daß die Hirnatrophie im Rahmen der Parkinsonschen Krankheit nicht durch arteriosklerotische Veränderungen verursacht wird.
    Notes: Summary Computed tomographic examinations of parkinsonian patients revealed a high incidence of cerebral atrophy, in most cases a combination of cortical atrophy and ventricular enlargement. The present study considered the relationship between cerebral atrophy and physical signs indicating or promoting arteriosclerosis such as overweight, electrocardiographic changes, hypertension, calcification of the internal carotid artery and aorta as well as elongation of the aorta. The study is based on 173 treated and untreated parkinsonian patients (89 men, 84 women) aged from 37–84 years (mean 64.6), on whom CT was performed about 5.4 years after the onset of the first symptoms of the illness. The results demonstrate an increase of pathological CT findings as well as of calcification in the carotid siphon with advanced age. No correlation was found between the other items and increasing age. Further analysis of the relationship between cerebral atrophy and signs of arteriosclerosis revealed only a statistically relevant correlation with calcification of the carotid siphon, especially with calcification of the media. Since pathological CT findings and calcification of the internal carotid artery are both related to advanced age, whereas all the other items which may be considered to be indications of arteriosclerosis do not have any clear relationship, it is concluded that the cerebral atrophy in Parkinson's disease is not caused by arteriosclerosis.

    Notes: Summary To clarify the importance of brain atrophy in relation to the symptoms of Parkinson's disease, 173 patients were examined by computed tomography (CT). In 51.4% of the CT findings, brain atrophy was considered to be pathological. Statistically significant relations of age and sex were found with regard to the extent and localization of brain atrophy. Cortical atrophy also showed a significant dependence on duration of disease. Linear measurements at the lateral ventricles and the third ventricle lead us to assume that brain atrophy in Parkinson's patients is more prevalent than in normal patients within the scope of age involution.

    Description / Table of Contents: Zusammenfassung An einer Stichprobe von 112 psychisch kranken Patienten wurde im Vergleich mit 70 körperlich Kranken analysiert, wie hdufig psychische Erkrankungen im Zusammenhang mit belastenden Lebensereignissen stehen. Es zeigten sich erhebliche Unterschiede der Life-event-Belastung zwischen den psychisch Kranken and der Kontrollgruppe sowie zwischen den einzelnen diagnostischen Gruppen. Die Life-event-Belastung war am ausgeprdgtesten bei den neurotisch Kranken. Auch bei den endogenen Psychosen, insbesondere bei den Schizophrenien, fand sich eine vermehrte Life-event-Belastung. Verschiedene Methoden (objektive Belastungswerte nach Paykel, vom Patienten angegebene Negativscores, Synthese aus objektiven and subjektiven Bewertungen) führten bei den Gruppenvergleichen zu vergleichbaren Resultaten. Vom Patienten als positiv bewertete Life-events standen nicht in Zusammenhang mit psychischen Erkrankungen.
    Notes: Summary A sample of 112 psychiatric inpatients were examined in comparison to 70 somatic inpatients with respect to the question, how frequent psychiatric diseases were in correlation with stressful life-events. There were significant discrepancies concerning life-event stress between the diagnostic subgroups. The life-event stress was most important in the neurotic patients, also patients suffering from endogenous psychoses, especially schizophrenics, showed an increased life-event stress. Different methods (objective stress scores suggested by Paykel, self-rating scores concerning negative experiences, and a synthesis between these two methods) led to similar results. Experiences, rated positive by the patients, showed no correlation with psychiatric diseases.
