The sense of ownership is the feeling that a body part belongs to ourselves. Brain damage may disrupt this feeling, leading to somatoparaphrenia (SP), i.e., the delusion that one's limbs belong to someone else. This delusional feeling is typically associated with profound motor and somatosensory deficits. We reviewed the cases of SP reported so far in the literature outlining the clinical and neuroanatomical profile of SP. We then investigated and reported three new peculiar cases of SP that allow new insights into the theoretical framework of this neuropsychological condition. We thus propose an innovative theoretical account that integrates previous evidence and the new cases described. We suggest that a defective update of the ongoing dynamic representation of the body finalised to perception and action, may be the key for the disownership feelings of patients with SP. The erroneous spatial representation of the limb contralateral to the lesion would have the logical consequence of delusional misattribution of the seen own arm.

Disturbances in time experience have been argued to play a significant, if not causative role in the clinical presentation of schizophrenia. Phenomenological considerations suggest a fragmented or dis-articulated time experience causing both primary symptoms such as hallucinations, delusions, and self-disorders, as well as an intersubjective desynchronization. We employed content analysis on material collected from patients diagnosed with schizophrenia using the Time Questionnaire to generate hypotheses on possible disturbances of time experience in schizophrenia. As a key result we find evidence for the distinction between acute psychotic and post-psychotic syndromes. Acute psychosis is predominantly a disturbance of the passage of time, whereas the remission from psychosis is primarily defined by changes in the experience of the explicit structure of time integrating past, present, and future. We discuss our findings with regards to previous insights and observations on time experience and time perception. We suggest our findings hold significance for the diagnostic and therapeutic understanding of schizophrenia as well as for future integrative research on time experience in general.

Alcohol-induced psychotic disorder is a rare complication of chronic alcohol abuse following abrupt alcohol cessation that is characterized by visual, auditory, or tactile hallucinations paired with intact orientation and stable vital signs, distinguishing the condition from delirium tremens and psychotic disorders. The condition, first termed alcoholic hallucinosis, has been described in medical literature for over a century, however, its nosologic classification and psychopathologic characteristics are less well-documented. One such case of alcohol-induced psychotic disorder with multimodal hallucinations of four months duration is described here.

The present paper aims to describe a case of a schizophrenia spectrum disorder relapse leading to attempted murder, review literature, and investigate the epidemiological data and expression of violent behavior among Capgras-related incidents. 109 case reports deriving from various scientific areas dating from 1971 to 2017 were evaluated and juxtaposed with an equivalent comparison group of random psychiatry inpatients, who were examined for the same variables. Quantitative and qualitative differences were observed between samples. High level of interpersonal violence was disclosed among Capgras-related incidents, especially towards the main care-givers, with higher propensity among male patients. Homicidal behavior was also expressed in higher levels among male patients experiencing the Capgras delusion. A multidisciplinary approach is vital for the optimal management of these incidents. Further research on the pathophysiology of Capgras delusion with the utilization of functional imaging techniques is of exceptional significance for the understanding of issues of neuroscience.

- Phenomenology and Course of Alcoholic Hallucinosis. [Journal Article]
- JDJ Dual Diagn 2019 Jun 04; :1-5
- CONCLUSIONS: Alcoholic hallucinosis is an acute short-lasting psychotic disorder which lasts for less than a week when treated. Suicidality is high in this group, which needs attention. Benzodiazepines as part of withdrawal management may be sufficient for a majority of cases. Antipsychotics may be required in selected cases. A high degree of recurrence and morbidity indicates a need to intervene early with an abstinence-oriented management goal.

In this paper, early detection of schizophrenia types such as hallucination and delusion propose through the high Q-factor of RADWT in EEG signal acquired during the cognitive task of the patient. The earlier diagnose obtains from the energy distribution of the EEG signal in the high resolution via optimum tuning in dilation factor,which influences the Q-factor, redundancy and ringing in the EEG signal. The early detection of type of schizophrenia prevents the illness progression and lifelong disease. In existing clinical trial, the psych clinician diagnose only the schizophrenia disease through the standard DSM screening question and Prodromal signs checklist according to the standard of American Psychiatric Association. Furthermore, clinician tries to diagnose the disease through brain imaging and EEG signal. However, procedure in the diagnosis of Schizophrenia possible only in the acute stage, minimum after 2 years of illness progression and still sub classification of the type of schizophrenia is a challenging task. In the proposed system, we acquire EEG signal during the three conditions such as reverse counting of the number, screening questions (DSM), and eye rest state with a distance of 1-m part of the clinician and patient to analyse cognitive behaviour. From the result of 25 patients EEG, signal during cognitive task show the different sub band energy pattern in RADWT to distinguish hallucination and delusion patient exactly for 21 patients and provide 84% of accuracy in sub-classification of type schizophrenia.

This article reviews cognitive models of positive and negative symptoms of schizophrenia, as well as basic principles of cognitive behavioural therapy (CBT) for hallucinations, delusions and negative symptoms. Cognitive models of schizophrenia posit that individuals' view of the self is influenced by a combination of genetic vulnerability, early childhood experience and environmental stressors later in the life, and that these factors determine how internal and external experiences are interpreted. Cognitive behavioural therapy for schizophrenia is based on the basic principles of CBT and establishes connection between thoughts, emotions and behaviour. Treatment focuses on the meaning the individual attributes to psychotic experience, his or her understanding of it and ways of coping with symptoms, and is intended to reduce the distress caused by psychotic experience and correct thoughts and assumptions that are incompatible with objective evidence. The latest contradictory data on the efficacy of CBT for schizophrenia point to the need to use protocols that are tailored to specific symptoms and subgroups of patients based on the stage of illness, level of neurocognitive impairment and severity of the disorder, and manual-based in order to ensure fidelity of implementation.

- Hyperprolactinemia - side effect or part of the illness. [Journal Article]
- PDPsychiatr Danub 2019; 31(Suppl 2):148-152
- CONCLUSIONS: Elevated prolactin in patients has been demonstrated regardless of antipsychotic therapy, therefore the question of etiology of hyperprolactinemia in psychotic disorders is questionable. The association of hyperprolactinemia with the severity of the clinical picture has also been demonstrated, higher prolactin values indicating a stronger clinical picture, which calls into question the protective role of prolactin in psychotic disorders.
