Delusion

Delusions


Presentation

  • High-PDI individuals responded faster to dot-probes presented in the same location as angry compared to happy faces at the short 200 ms stimulus onset asynchrony (SOA), but only when the emotional faces were presented to the left visual field.[ncbi.nlm.nih.gov]
Burning Pain
  • The patient initially suffered from dysesthesia and burning pain typical of thalamic pain syndrome and subsequently developed delusional oral parasitosis ("worms" infesting her mouth).[ncbi.nlm.nih.gov]
Asymptomatic
  • RESULTS: A 75-year-old male with a 13-year history of progressive AD, asymptomatic bipolar disorder, chronic kidney disease, hypertension, hyperlipidemia, and benign prostatic hypertrophy presented to the ED with recurrent/escalating violence toward his[ncbi.nlm.nih.gov]
Dysesthesia
  • The patient initially suffered from dysesthesia and burning pain typical of thalamic pain syndrome and subsequently developed delusional oral parasitosis ("worms" infesting her mouth).[ncbi.nlm.nih.gov]
Thalamic Pain
  • The authors describe a case of an unusual association of delusional parasitosis and thalamic pain syndrome after left-posterior thalamic hemorrhage.[ncbi.nlm.nih.gov]

Workup

  • (See Prognosis, Clinical Presentation, Differentials, Workup, and Treatment .) Chronic intake of alcohol affects several neurotransmitter systems in the brain.[emedicine.com]
Hyperprolactinemia
  • In light of this clinically striking temporal association between hyperprolactinemia and delusion of pregnancy, we review the literature to examine the hypothetical relationship.[ncbi.nlm.nih.gov]
Ischemic Changes
  • On neuroimaging, four patients exhibited frontal lobe changes, four demonstrated generalized volume loss, and five had ischemic changes; seven patients demonstrated right-sided or bilateral hemisphere lesions.[ncbi.nlm.nih.gov]

Treatment

  • A number of effective treatments are available.[ncbi.nlm.nih.gov]
  • Treatments Delusional disorder treatment often involves atypical (also called novel or newer-generation ) antipsychotic medications, which can be effective in some patients.[minddisorders.com]

Prognosis

  • Prognosis The outlook varies. Although the disorder can go away after a short time, delusions also can persist for months or years. The inherent reluctance of a person with this disorder to accept treatment makes the prognosis worse.[drugs.com]
  • The prognosis for clients with delusional disorder is largely related to the level of conviction regarding the delusions and the openness the person has for allowing information that contradicts the delusion.[minddisorders.com]
  • At discharge, the GAF score was significantly higher in delusional disorder, which suggests a better prognosis ( Table 1 ).[doi.org]
  • (See Prognosis, Clinical Presentation, Differentials, Workup, and Treatment .) Chronic intake of alcohol affects several neurotransmitter systems in the brain.[emedicine.com]

Etiology

  • Various types of explanations have been proposed regarding the etiology of delusional belief in dementia, and cerebral correlates are considered. Pharmacological and non-pharmacological treatments are analyzed. 2013 Japan Geriatrics Society.[ncbi.nlm.nih.gov]

Epidemiology

  • Epidemiology A UK study found that 39% of a sample of 1,000 randomly selected people completing a questionnaire (the Cardiff Beliefs Questionnaire) reported having at least one strong delusional-like belief. [ 6 ] An American study of the general population[patient.info]

Pathophysiology

  • Nondominant hemisphere lesions may play a role in the pathophysiology. A number of effective treatments are available.[ncbi.nlm.nih.gov]
  • The basal ganglia are involved also in the pathophysiology of Parkinson's disease, Huntington's disease, and tardive dyskinesia.[web.archive.org]

Prevention

  • Prompt identification and management of underlying cause would definitely prevent further complication and would also prevent the child from exposing unnecessary with various pharmacological treatments.[ncbi.nlm.nih.gov]
  • Prevention Little work has been done thus far regarding prevention of the disorder. Effective means of prevention have not been identified. Resources BOOKS American Psychiatric Association.[minddisorders.com]
  • Prevention There is no known way to prevent this disorder. Treatment Treatment for this disorder is challenging, especially if the delusion is long lasting.[drugs.com]
  • PREVENTING PEACE Physicians have a motto that peacemakers would do well to adopt: "First, do no harm." Neither the United States nor the United Nations have quite grasped this.[foreignaffairs.com]
