The term "Cotard's syndrome" is used to describe a number of clinical features, mostly hypochondriac and nihilistic delusions, the most characteristic of which are the ideas "I am dead" and "my internal organs do not exist". Besides, anxious and depressed mood, delusions of damnation, possession and immortality, suicidal and self-mutilating behavior are included. The first description of the syndrome was made in 1880 by Cotard, who presented the case of a female patient in a lecture. He originally named it "hypochondriac delusion", and some years later "delusion of negations", while it was named "Cotard delusion" after his death. In international literature, the terms "nihilistic delusion" and "Cotard's syndrome" prevailed over "delusion of negations" and "Cotard delusion". In the present study we report the case of a 59 year-old woman, who was admitted to our department after a suicide attempt, and who showed symptoms of Cotard's syndrome for about two years, namely depressed mood, hypochondriac and nihilistic delusions, delusions of immortality and damnation, suicidal ideation, severe psychomotor retardation, diminished motivation and tendency to stay in bed. She never took the medication she was prescribed, and at times she refused to eat. During her hospitalization, there was performed a full blood panel and medical imaging, that showed chronic ischemic infarctions, periventricular leukoencephalopathy and diffuse cerebral atrophy in MRI. All the other test results were normal. She was administered treatment with haloperidol, mirtazapine and venlafaxine. Gradually, her psychomotor ability, motivation and mood improved, she didn't express suicidal ideation, her delusions were less intense and she was able to question them, but they weren't eliminated. She was discharged in improved condition, after 44 days. Cotard's syndrome isn't mentioned in the current classification systems (ICD-10, DSM-5). In literature though, it has been divided into three types, according to the clinical symptoms: psychotic depression, Cotard type I, and Cotard type II, and three stages have been proposed: germination stage, blooming stage and chronic stage. It has been associated with various medical conditions, such as cerebral infractions, frontotemporal atrophy, epilepsy, encephalitis, brain tumors, traumatic brain injury. Furthermore, it has been associated with psychiatric conditions, such as mental retardation, postpartum depression, depersonalization disorder, catatonia, Capgras syndrome, Fregoli syndrome, Odysseus syndrome, koro syndrome. Several reports about successful pharmacological treatments have been published, both monotherapies with antidepressants, antipsychotics or lithium, and by antidepressant and antipsychotic combination treatments. The most reported successful treatment strategy for Cotard's syndrome is electroconvulsive therapy (ECT), administration of which should follow current treatment guidelines of the underlying conditions.

Suicide is a major problem for psychiatry. Depression is the most common mental disorder related to suicidal behavior. The present study aimed at investigating the relationship between the symptomatology related to death, dying, and suicide and neurobiological factors in depressed patients. Fifty patients aged 21–60 years suffering from major depression were investigated. Schedules for Clinical Assessment in Neuropsychiatry version 2.0 and the International Personality Disorder Examination were used to assist the clinical diagnosis. The psychometric assessment included the Hamilton Depression Rating Scale, the Hamilton Anxiety Scale, the 1965 and 1971 Newcastle Depression Diagnostic Scales, the Diagnostic Melancholia Scale, the General Assessment of Functioning Scale, and the Personality Deviance Scale. Psychophysiological methods included electro-oculogram, flash electroretinogram under photopic and scotopic conditions, and pattern-reversal visual evoked potentials. Biological markers included the 1-mg dexamethasone suppression test, the 30-mg dexfenfluramine challenge test, and brain ^99mTc-HMPAO SPECT. Statistical analysis included one-, two-, and three-way Manova and Mancova and the Scheffé test as post hoc test. Patients without thoughts of death had higher self-confidence levels and less overdependency on others and intropunitiveness. The suicidal patients had a significantly prolonged pattern-reversal visual evoked potential latency in comparison with the other patients. The findings of this were related to the status of the patient at the time of the interview but not to his/her history. They also provide neurobiological data to support the need for a combined presence of self-directed aggression and a higher arousal level or disinhibition of self-directed aggressive thoughts in order for a patient to become suicidal. Further study is needed to test whether psychophysiological methods, which are noninvasive and easy to perform, are of value in the therapeutic planning and monitoring of responses.

To study the functional organization of the cerebral hemispheres in patients with bipolar psychosis using a verbal dichotic listening test for pairs of digits 26 patients were tested twice, during the acute expression of manic phase and after recovery. The patient group during the manic phase did not support the expected right-ear advantage of normal subjects on verbal dichotic tests but showed a statistically significant left-ear advantage, which shifted after recovery toward the typical normal asymmetry. Comparing patients during the manic phase and after recovery showed that the left-ear advantage as well as the shift in right-ear advantage after recovery was due to the reduction of left-ear performance. From the over-all neuropsychological findings for these patients mania may be hypothesized to be characterized by overactivation of the right hemisphere. This phaenomenon seems associated with acuteness of the symptoms of the psychotic disorder.

Introduction: The present study aimed to search for correlations between melatonin (MT) levels and the dexamethasone suppression test (DST) and clinical variables. Methods: Fifty depressed patients aged 21–60 years took part in the study. The Schedules for Clinical Assessment in Neuropsychiatry, version 2.0, and the International Personality Disorders Examination were used for diagnosis. Psychometric assessment included the Hamilton Depression Rating Scale, the Hamilton Anxiety Scale, the General Assessment of Funtioning Scale, the Newcastle scales and the Diagnostic Melancholia Scale. The DST and 9.00 and 23.00 h MT values were assessed. Statistical analysis included Student’s t test, Pearson product moment correlation coefficient and forward stepwise multiple linear regression analysis. Results: Melancholic patients had lower 23.00 h MT values in comparison to the rest of the patients and the atypical and ‘undifferentiated’ patients. Conclusion: The current study shows that low MT values were closely related to melancholic depression. Distinct quality of mood, psychomotor agitation or retardation and anorexia or weight loss seemed to be responsible for this relationship.

The objective of this cross-sectional survey was to estimate the association between multiple socioeconomic, and health-related characteristics, COVID-19 related attitudes and adoption of public health preventive behaviors. A national cross-sectional survey among 1205 adults was conducted in April 2020 in Greece. Multivariable ordered logistic regression models were used to estimate the association between COVID-19 related attitudes and knowledge and adoption of preventive behaviors, controlling for socioeconomic and health-related characteristics. A total of 923 individuals fully completed the survey. Individuals who believed that the virus is out of control, is transmitted through the air, and is not similar to the common flu were more likely to adopt public health preventive behaviors more frequently, particularly wearing masks in public spaces, washing their hands, and spending fewer hours out of their homes. Uncertainty about the virus symptomatology was associated with less frequent mask-wearing and handwashing. Increased social support, frequent media use for COVID-19 updates, trust to authorities, older age, worse health status, female gender and being a healthcare professional were also associated with uptake of some preventive health behaviors. Attitudinal and socioeconomic determinants critically affect public engagement in preventive behaviors. Health policy initiatives should focus on community outreach approaches to raise awareness and to strengthen social support mechanisms by integrating multiple stakeholders.
