An episode of delirium can dramatically worsen the trajectory of an underlying dementia (Inouye effexor xr 37.5mg low cost, 2006; Fong et al effexor xr 150 mg without a prescription, 2009b). Oberai et al (2018) reviewed studies of multicomponent intervention and found a reduction in reducing incidence. In efforts to prevent delirium, the following points are recommended: • Routine cognitive testing on admission and during hospitalization • Ensure the continued use of glasses and hearing aids as appropriate Pridmore S. Last modified: January, 2018 7 • Ensure adequate intake of fluids and nutrition by providing assistance as necessary • Early identification and treatment of dehydration • Early mobilization • Avoid physical restraints (Fick, 2011). With respect to older person post hip surgery management, opioid use is not associated with delirium in patients with or without dementia (Sieber et al, 2011). Basic laboratory testing includes complete blood count, electrolytes and renal function tests, oxygen saturation, ECG, urinalysis and chest X-ray. Somewhat unexpectedly, intracranial factors are rare and should be considered only when all other factors have been excluded, or if there are focal neurological signs. Curative pharmacological agents such as antibiotics should be applied as indicated. The presence of family members at the bed-side is reassuring. Anxiolytic medication (particularly benzodiazepine) is best avoided, because of the real risk of worsening matters. Symptom controlling pharmacological agents may be necessary with combative and disturbed behaviour. Quetiapine, however, has recently been described as being effective and safe for the treatment of delirium in both general medicine and intensive care units (Hawkins et al, 2013). Olanzapine and haloperidol decrease the severity, and Rivastigmine (an anticholinesterase inhibitor) reduces the duration of delirium (Cerveira et al, 2017) Pridmore S.

Possible difference between the delusions of delusional disorder and the delusions of other disorders The following generalizations has some clinical relevance: Delusional disorder Other disorders not bizarre Bizarre Systematized Not systematized Charlton and McClelland (1999) observed that in delusional disorder there is fundamental mistake about the motives of others generic effexor xr 75mg fast delivery, but that thereafter buy effexor xr 150 mg overnight delivery, the thinking processes are logical, while in other disorders with delusions, there is evidence of many breaks in logic. Further, the delusions of Delusional disorder can be understood in an evolutionary context. The delusions of delusional disorder fit into 5 main categories: 1) belief of threat Pridmore S. Last modified: November, 2015 7 from gangs or organizations, 2) belief (particularly by the male) of infidelity of the spouse, 3) belief (particularly by females) that a high status individual is in love with the patient, 4) belief of a life threatening disease, and 5) belief of an unattractive bodily/facial deformity (in DSM5, this last example has been removed from Delusional disorders and placed under Obsessive-Compulsive and Related Disorders). Successful evolution requires the transmission of genes, and this is better achieved if the individual lives a long life and is attractive to members of the opposite sex. Accordingly, the 4 categories of delusional disorder may be linked to the facts that in the ancestral environment, 1) homicide by gangs (other tribes) was a major cause of mortality, 2) infidelity by the female spouse meant the supportive male was contributing to the welfare of the genes of another male, and 3) presence of disease, or 4) deformity may reduce attractiveness to members of the other gender, and thus reduce the chances of passing on genes. This may reflect the presence of disorder of the form of thought, that is, where there is loss of logical connection between ideas. The delusions of both delusional disorder and other disorders often have some grandiose content. It is has been observed that for a delusion of persecution (bizarre or otherwise) to be present, the individual must be “important” enough to warrant the attention of others. Unknown prevalence of delusional disorder The prevalence of Delusional disorder is uncertain. People with this disorder can often function reasonably well in the community. Lacking insight, they usually do not believe they have a mental disorder and do not go to the doctor for help. Feeling persecuted, they often avoid contact with others and try to attract as little attention as possible. In large blocks of flats there are often people who have many locks on their doors, who believe that the neighbours come into their residences and move things around or steal things during the night. Some people with delusional disorder are well known to the police as they make frequent calls about being persecuted. Elderly sufferers are occasionally encountered who have been crippled by their delusions for decades. Much effort has been directed toward proving this theory, with some, but limited (so far) success. Last modified: November, 2015 8 It has long been known that most people with schizophrenia (which often features delusions) have some cognitive (thinking) deficits. Recent work on delusional disorder (Ibanez-Casas et al, 2013) has also demonstrated cognitive deficits in this disorder. The field is complicated and packed with many unfamiliar terms and definitions, many of which overlap. Much of this research is conducted by psychologists who are skilled in measuring cognition. For a taste of the topic, a few findings will be inexpertly mentioned. Subtle defects in the attention and memory of people with delusions have been identified (Leposavic et al, 2009), which may impair the ability to learn (accept) new (and contradictory) information. However, a recent large study (Kontaxaki et al, 2014) measured attention, memory, executive functions and speech in psychotic subjects and found that delusions do not associate with any subtype of cognitive deficit. Among the proposed faulty thinking habits is Jumping to Conclusions (JTC). The idea is that patients JTCs too rapidly, without gathering all available information, and thus form a delusion. Many factors count against the usefulness of the concept of JTC bias (Reese et al, 2011; Jolley et al, 2014). Nevertheless, a very recent meta-analysis (Dudley et al, 2015) found that “non-affective psychosis is characterized by a hasty decision-making style, which is linked to an increase probability of delusions”. Metacognitive Training (MCT) (Moritz et al, 2014) is a structured therapy drawing on Cognitive Behaviour Therapy (CBT) and educational techniques. Although reported with enthusiasm, the benefits of these therapies is doubtful (Waller et al, 2011; Kuokkanen et al, 2014; Mehl et al, 2015). Last modified: November, 2015 9 The pathophysiology of delusions is uncertain and probably differs from one disorder to another. Dysfunction of prefrontal and temporal lobes (Leposavic et al, 2009) and the basal ganglia (Morrison and Murray, 2009) has been suggested. Dysregulation of dopamine (hardly surprising as dopamine blockade is the most successful treatment) endocannabinoid and adenosine systems may be involved (Morrison and Murray, 2009). Dopamine dysregulation projecting to the ventral striatum may increase the salience of irrelevant stimuli leading to delusion formation (Pankow, 2012).
