Ramachandran and Blakeslee proposed that the idea \"I am dead\" comes to mind when a neuropathological condition has resulted in complete abolition of emotional responsivity to the world. The idea would arise as a putative explanation: if \"I am dead\" were true, there would be no emotional responsivity to the world.Methods: We scrutinised the literature on people who expressed the delusional belief \"I am dead\", looking for data on whether such patients are reported as entirely lacking in emotional responsivity.Results: In numerous cases, patients with Cotard delusion are described as experiencing emotions including anxiety, fear, guilt, distress, euphoria and worry.Conclusions: We conclude that complete absence of emotional responsivity cannot be what prompts the delusional idea that one is dead. We propose that, in at least some cases, the idea \"I am dead\" comes to mind in response to symptoms of depersonalisation or derealisation, often present in cases of Cotard delusion, and give examples of Cotard patients with abnormalities in various neural areas that could be responsible for the presence of such symptoms.","PeriodicalId":51277,"journal":{"name":"Cognitive Neuropsychiatry","volume":"27 6","pages":"430-446"},"PeriodicalIF":1.7,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10631891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesised that both SCF scales would be highly correlated, minimally associated with OCF, and similarly associated with depressive symptoms. Methods: Archival clinical data from 52 TRP inpatients was utilised. OCF composite scores were derived from a broad neuropsychological battery. SCF was assessed using the norm-referenced PROMIS 2.0 Cognitive Abilities (positively worded) and Concerns (negatively worded) subscales. A depressive symptom score was derived from the Positive and Negative Syndrome Scale. Results: SCF ratings were higher in patients than OCF. There was a small but significant correlation between PROMIS subscales (r = .30). Neither PROMIS subscale was associated with OCF (r = -.11, r = .01). Depressive symptoms were correlated with the positively (r = -.29) but not negatively worded scale (r = -.13). Conclusion: Individuals with TRP inaccurately rate their cognitive functioning and tend to overestimate their ability. Positively and negatively worded SCF scales associate variably with depressive symptoms, indicating they may not be used interchangeably in TRP.","PeriodicalId":51277,"journal":{"name":"Cognitive Neuropsychiatry","volume":"27 6","pages":"411-429"},"PeriodicalIF":1.7,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9198650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using path analysis, we explored the complex interplay between schizotypy, metacognitive beliefs, cognitive insight, and symptoms of emotional distress.Methods: Self-report data of schizotypy, metacognitive beliefs, cognitive insight, depression, and anxiety symptoms were collected from 344 participants from a predominantly student sample.Results: Path analysis confirmed unique associations between schizotypy dimensions, metacognitive beliefs, and cognitive insight. Furthermore, negative beliefs about worry mediated the link between the schizotypy dimensions, unusual experiences, cognitive disorganisation, and introvertive anhedonia and both depression and anxiety symptoms. Lack of cognitive confidence also mediated the relationship between cognitive disorganisation and depression symptoms. Finally, the cognitive insight subcomponent self-reflectiveness mediated the relationship between unusual experiences and cognitive disorganisation and anxiety.Conclusions: This study significantly furthers our understanding of the complex relationship between schizotypy, metacognitive processes, and emotional distress.

The analysis also showed similar vividness for intentionally fabricated memories and real ones in AD patients but lower vividness for intentionally fabricated memories than for real ones in control participants.Conclusions: The slow retrieval time of intentionally fabricated memories may be attributed to the cognitive effort required to retrieve elements from autobiographical memory and edit them to construct a new memory.
