Paramnesic delusions are rare psychiatric sequelae after head injury. In a follow-up of 346 patients only three such cases were seen. Case histories of those patients with a follow-up for eighteen months, their clinical features, psychometric evaluations etc. are described, followed by a discussion into their genesis and persistence.
Optimism is generally accepted by psychiatrists, psychologists and other caring professionals as a feature of mental health. Interventions typically rely on cognitive-behavioural tools to encourage individuals to 'stop negative thought cycles' and to 'challenge unhelpful thoughts'. However, evidence suggests that most individuals have persistent biases of optimism and that excessive optimism is...
Previous research has found that reduced self-reassurance and heightened verbal 'self-attacking' of a sadistic and persecutory nature are both associated with greater subclinical paranoia. Whether these processes are also linked to clinical paranoia remains unclear. To investigate this further, we asked 15 people with persecutory delusions, 15 people with depression and 19 non-psychiatric contr...
“Under conditions of unrelieved adversity and failure, narcissists may decompensate into paranoid disorders. Owing to their excessive use of fantasy mechanisms, they are disposed to misinterpret events and to construct delusional beliefs. Unwilling to accept constraints on their independence and unable to accept the viewpoints of others, narcissists may isolate themselves from the corrective ef...
Delusions are the persistent and often bizarre beliefs that characterise psychosis. Previous studies have suggested that their emergence may be explained by disturbances in prediction error-dependent learning. Here we set up complementary studies in order to examine whether such a disturbance also modulates memory reconsolidation and hence explains their remarkable persistence. First, we quanti...
Diagnostic criteria for subtypes of delusional beliefs based upon content have rarely been the subject of comment. In this article, several influential accounts of persecutory delusions are reviewed; differences and difficulties are noted, and their potential effect on cognitive psychological investigations discussed. One method of ensuring that researchers study similar phenomena is to use a m...
Control of schistosomiasis in Venezuela has been a topic of major interest and controversy among the metaxenic parasitosis. A small area of transmission of approximately 15,000 km2 was thought to be eradicated some years ago. However, some epidemiological characteristics of our transmission area have limited the success on the way toward eradication. Since 1945, when the Schistosomiasis Control...
BACKGROUND The "jumping to conclusions" (JTC) data-gathering bias is implicated in the development and maintenance of psychosis but has only recently been studied in first episode psychosis (FEP). In this study, we set out to establish the relationship of JTC in FEP with delusions and neuropsychological functioning. METHODS One hundred and eight FEP patients and 101 age-matched controls compl...
Videoconferencing has become an increasingly viable tool in psychiatry, with a growing body of literature on its use with a range of patient populations. A number of factors make it particularly well suited for patients with psychosis. For example, patients living in remote or underserved areas can be seen by a specialist without need for travel. However, the hallmark symptoms of psychotic diso...
The literature on chronic pruritus, paresthesia and delusional infestation indicates that a wide variety of conditions ranging from AIDS to vitamin deficiencies may cause these symptoms. In many, or perhaps most of these cases, activation of itch pathways seems to be the underlying cause of the skin sensations and perhaps even the visual hallucinations characteristic of delusional infestation. ...
