Persecutory Delusion
  • Two weeks later patient suddenly developed delirium, characterized by nocturnal agitation, severe insomnia, daytime sedation, confusion, hallucinations and persecutory delusions.[ncbi.nlm.nih.gov]
  • Psychosis from cocaine or amphetamine use typically produces persecutory delusions . Hallucinogens can, of course, cause visual, auditory, and tactile hallucinations, but this is not the same as psychosis.[americanaddictioncenters.org]

Agitated Delirium
  • Medications that are often used to treat agitated delirium include haloperidol , thioridazine and risperidone .[minddisorders.com]
  • Very rarely, a person with severe, agitated delirium that does not get better with treatment may need controlled sedation. Sedation is the use of drugs that put a patient into a deep sleep.[cancer.net]
  • The condition is sometimes referred to by other names such as: “Bell’s mania,” agitated delirium, acute exhausted mania, and lethal catatonia.[mentalhealthdaily.com]
Neurologic Manifestation
  • When you have a medication with a known psychoactive element which directly or even indirectly alters brain chemistry and or causes neurological manifestations such as being "intoxicated", "high", "relaxed", "sleepy" etc. and the patient becomes confused[forums.acdis.org]

Treatment

  • Understanding your loved one’s mental capacity may affect treatment options. Someone experiencing strong delirium will benefit from professional substance abuse treatment.[alcoholanddrugsrehab.com]
  • Drug treatment aimed at sedation should be introduced for specific indications, such as aggression, risk of harm to self or others, hallucinations, patient distress, and where compliance with therapy or procedures is essential.[ncbi.nlm.nih.gov]
  • The patient began a treatment with quetiapine 25mg/day for two days, then twice a day, and infusion of saline 1000 ml/day for two days; psychiatric symptoms gradually diminished and therapy with galantamine was begun.[ncbi.nlm.nih.gov]
  • Reported here are two cases of “probable” acute cognitive impairment following treatment of nausea with olanzapine.[apm.amegroups.com]
  • Successful treatment of delirium depends on identifying the reversible contributing factors, and drugs are the most common reversible cause of delirium.[ncbi.nlm.nih.gov]

Prognosis

  • This information will be very helpful for treatment providers, as the course and prognosis of delirium may differ whether it is triggered by drug intoxication or withdrawal.[alcoholanddrugsrehab.com]

  • Patients with malignancy or HIV also have a worse prognosis. [ 4 ] Prevention [ 1 ] Awareness of high-risk patients and subsequent close observation for delirium with prompt assessment and management can potentially reduce morbidity and mortality.[patient.info]
  • Prognosis If a quick diagnosis and treatment of delirium occurs, the condition is frequently reversible.[minddisorders.com]

Etiology

  • Otherwise, most tests will be used for ruling out other etiologies of alteration in mental status other than delirium.[clinicaladvisor.com]
  • There must also be evidence that the delirium is due to a direct physiological consequence of another medical condition, substance intoxication or withdrawal, or exposure to a toxin, or is due to multiple etiologies.[mariayang.org]
  • There is evidence from the history, physical examination, or laboratory findings of either (1) or (2): (1) the symptoms in Criteria A and B developed during Substance Intoxication (2) medication use is etiologically related to the disturbance* Note: This[behavenet.com]
