A delirium

S When the priests wanted to commune with their gods and receive messages from them, they ate this plant to induce a delirium. A thousand visions and Satanic hallucinations appeared to them (11). 

Glucocorticoids are known to produce mental changes that range from moderate mood changes, severe depression, and euphoria to psychosis. Steroid psychosis is characterized by a delirium and a clouded sensorium. The onset of symptoms usually occurs within 5 to 30 days after therapy is initiated. The incidence rate appears to correlate closely with dosage level (a rate of 1.3% when the dose was 40 mg or less 4.6% when it was between 41 and 80 mg and 18.4% when it was 80 mg or more. 

The mental status examination remains an essential part of the evaluation. Often patients with schizophrenia will appear nnkempt or otherwise oddly dressed. Sometimes they will be friendly and affable, but when they are paranoid, they can be angry and hostile. Patients may have odd stereotypical movements that can become extreme in catatonic states. The patient with schizophrenia is usually quite alert and well oriented to his/her surroundings. This observation helps to distinguish the psychosis of schizophrenia from that of a delirium due to a medical illness or substance use. 

D. The disturbance does not occur exclusively during the course of another mental disorder (e.g., major depressive disorder, generalized anxiety disorder, a delirium). 

Identifying delirium quickly can save your patient s life. Its treatment requires identifying the underlying cause and eliminating it. One important point to remember is that patients with dementia can also become delirious. The most common scenario is a patient with moderate dementia who is incontinent of urine and wears a protective undergarment. If such a patient rapidly deteriorates, it is probably not due to the dementia. Instead, this patient likely has a bladder infection that is superimposing a delirium on the dementia. By treating the bladder infection with antibiotics, the patient can quickly return to their baseline state. 

Although many physicians routinely use benzodiazepines to treat combative, delirious patients, this is not recommended. First, benzodiazepines can cloud consciousness and actually worsen the confusion of delirium. Second, benzodiazepines can worsen the breathing problems of patients with pneumonia or emphysema, two common causes of delirium. The lone exception is a delirium that is caused by alcohol or benzodiazepine withdrawal. A benzodiazepine MUST be used for alcohol...

The treatment of patients during a delirium tremens episode includes the intravenous administration of another CNS depressant (usually diazepam) during the acute phase, followed by the oral administration of chlordiazepoxide or oxazepam. In addition, other medications and dietary management may become essential. 

Withdrawal from sedative-hypnotics may be accompanied by a delirium that can be life threatening. In severe withdrawal, seizures, visual, tactile, or auditory hallucinations may occur. 

Systemically it is a stimulant to all parts of the central nervous system including the brain, the spinal cord, and the medulla. Its effects upon the brain are shown by an exaltation of the intellectual faculties similar to that which is produced by caffeine. In overdose it produces a delirium somewhat suggesting that of atropine, to which it is chemically related Its action upon the spinal cord is shown by increased activity of the reflexes but the convulsions which are seen in cocaine poisoning both in the lower animals and in man seem to be due to an action upon...

There s often a delay between the underlying problem resolving and a delirium clearing (e.g. in some cases it can take months).

Cases cf Neurotoxicity Toxicity at therapeutic or subtherapeutic levels was reported in three cases. In two of these cases, the role of lithium is questionable. In one case of a rapidly fatal presentation of neuroleptic malignant syndrome (NMS) in a 72-year-old woman whose lithium level was 1.5 mM, the authors report a lithium-induced fatal NMS because she was not prescribed an antipsychotic [84 ]. However, her presentation is also consistent with fatal catatonia, sepsis, or unknown consumption of an antipsychotic, none of which were ruled out, and all of which are more likely than lithium-induced NMS. A second case in which a delirium with dyspraxia, but not ataxia in a 57-year-old man with a lithium level of 0.44 mM, that resolved after discontinuation of botii lithium and tricyclic antidepressant medication, was felt to be an interaction between the lithium and the antidepressant [85 ]. Lithium may have played a role, but he had been on lithium for years, and had developed anticholinergic problems with quetiapine previously, suggesting that the anticholinei c effects of the tricyclic antidepressant were more important in the delirium than the lithium. The third case of a 65-year-old man with multisystem atrophy becoming considerably worse with lithium at a level of 1.1 mM, is much more likely to represent lithium-related neurotoxicity at therapeutic levels [86 ].
