Critical care patients become confused in the intensive care setting. Several dangers exist in acute confusional states. Confused patients jeopardize their own safety, are more likely to die than nonconfused patients and are more likely to become cognitively impaired and require institutionalization. This article reviews the literature about patients experiencing acute confusional states in the critical care setting including intensive care unit (ICU) psychosis, postcardiotomy delirium and confusion in the elderly.

All incident cases of clinically diagnosed Alzheimer's disease were identified through the unique record linkage system of the Mayo Clinic. Thirty-nine (32%) of the sample of 122 had a psychiatric history that preceded the onset of CDAD by at least 3 years. Twenty-five percent of the study population had had an episode of delirium within 2 years of the onset of CDAD. Eighty-four percent of the cases had psychiatric symptoms in the course of CDAD that were documented in their medical records. Specific symptom patterns included agitation, combativeness, confusion and disorientation, depression, psychosis, and wandering. These symptoms occurred more frequently in clusters than singularly.

Patients with epilepsy have a higher incidence of psychosis. Epilepsy-related psychotic behaviors include a chronic interictal schizophreniform illness, an "alternating psychosis" which remits with seizure activity, and ictal or perictal psychotic behaviors. In addition, there is an uncommon and less understood psychosis characterized by brief psychotic episodes during the postictal period. This report describes two patients with postictal psychosis and correlates their behavior with the pattern of seizures, electroencephalographic discharges, and anticonvulsant and psychotropic medications. The findings suggest that postictal psychosis results from increased epileptiform activity and continued cerebral dysrhythmia, has a latency in onset and is not due to the immediate postictal delirium, and reflects an exacerbation of underlying psychopathological tendencies. This report further discusses the potential pathophysiological mechanisms and management of this disorder.

It is evident that human immunodeficiency virus (HIV) infection is one of the most serious public health issues in decades. HIV infection compromises cell-mediated immunity which ultimately may result in the acquired immunodeficiency syndrome (AIDS). AIDS, to date, remains an incurable and progressively fatal disorder. HIV infection is spreading beyond the originally identified high-prevalence groups of gay/bisexual males, intravenous drug abusers, and recipients of infected blood or blood products. Today, more and more heterosexual males, women, adolescents, and children have been infected with this lethal virus. This report addresses some of the psychiatric complications associated with HIV infection and discusses the diagnostic and clinical management challenges that clinicians must face as they deal with the increasing population of HIV-infected patients. Depression, anxiety, psychosis, delirium, and dementia are commonly encountered disorders associated with HIV spectrum disorders which must be accurately identified and can be effectively managed with psychopharmacological interventions.

A case of normal pressure hydrocephalus (NTH) complicated by delirious psychosis in the initial phase is described. A history of alcohol abuse made the diagnostic assessment difficult. Normal pressure hydrocephalus (NTH) should be considered in cases of delirium with dementia and histories of disturbances of gait or incontinence of urine.

A 30-year-old man with sarcoidosis was reported. The initial presentation of sarcoidosis was psychiatric symptoms which included abnormal behavior, hallucination and delirious state. After complete remission of these symptoms, eight months later, organic psychosis reappeared with corectopia, bilateral sensory deafness and staggering gait of bilateral vestibular origin. On admission there was no hilar lymphnode enlargement in chest roentgenogram nor raised angiotensin-converting enzyme (ACE) in serum and it was difficult to make diagnosis. Fourteen months after the onset of psychotic symptoms, bilateral facial palsy appeared and they led us to correct diagnosis of sarcoidosis by reinvestigation of the lesions of the chest. It seemed that corectopia indicated lesion of midbrain tegmentum and deafness and staggering gait indicated bilateral VIIIth nerve dysfunction. ACE and IgG-synthesis rate in the cerebrospinal fluid was raised against normal values of ACE and IgG in the serum. These findings seemed to contribute to the early diagnosis of sarcoidosis which had a selective activity in the central nervous system.

1. The authors review the literature describing acute symptomatology produced by the gradual or abrupt withdrawal of heterocyclic antidepressants, monoamine oxidase inhibitors (MAOI) and neuroleptics. 2. Withdrawal of heterocyclic antidepressants and antipsychotic agents causes similar symptomatology. Symptoms produced by the discontinuation of these drugs include nausea, emesis, anorexia, diarrhea, rhinorrhea, diaphoresis, myalgias, paresthesias, anxiety, agitation, restlessness, and insomnia. 3. Psychotic relapse is often presaged by anxiety, agitation, restlessness, and insomnia. Prodromal symptoms are distinguished from the effects of neuroleptic withdrawal by a temporal relationship of the latter to reductions in the dosage or discontinuation of antipsychotic agents. 4. Withdrawal of MAOIs can result in severe anxiety, agitation, pressured speech, sleeplessness or drowsiness, hallucinations, delirium, and paranoid psychosis. 5. MAOI withdrawal phenomena resemble the symptoms produced by the discontinuation of chronically administered psychostimulants. 6. The capacity of MAOIs to exert amphetamine-like effects presynaptically and the propensity of somatic treatments for depression to subsensitize presynaptic receptors regulating the release of catecholamines provide a basis for the development of psychotic symptoms upon the withdrawal of MAOI. Evidence for this hypothesis is reviewed.

Postanesthetic delirium is a type of postoperative emotional response occurring immediately after emergence from general anesthesia. Associated with excitement and confusion, the alternative terms emergence delirium or postanesthetic excitement are frequently used. Historically, the more encompassing term postoperative psychosis is used interchangeably but more frequently refers to those conditions occurring after a lucid interval of 24 to 48 hours. Either phenomenon may arise from a variety of disturbances, with drug reactions, hypoxemia, or reaction to pain being common, or it may arise from psychological causes. Reported is a case of postanesthetic delirium in a healthy young man. An historical overview of this potentially harmful condition, with specific recommendations for diagnosis and treatment, also is presented.

Maccario et al. described, in 1987, the case of an HIV-positive patient whose psychotic symptomatology was the expression of right centrum semi-ovale lesion. We report the case of a patient who suffered a sudden delirium, expression of a probable right lenticular cerebral toxoplasmosis. This 35-year-old male homosexual, who had no psychiatric history, suddenly developed in November 1988 the following psychiatric signs: he started to walk back and forth incessantly, he had the impression that he was the subject of the conversations of the passers-by, that all the posters and notices refer to him, and that he was God. He was admitted in a psychiatric department where the symptoms were progressively curbed by neuroleptics (cyamemazine 75 mg, and haloperidol 15 mg). The episode was not questioned by the patient, but attributed to bad eating habits. HIV-positivity had been discovered a year later (during systematic screening). A computerized tomographic (CT) scan performed subsequently to this delirium was interpreted as normal. Four weeks later the patient was referred to us. The psychiatric condition was stabilized in spite of a certain aggressiveness and the probable persistence of an underlying delirium state. Laboratory examinations showed the following: blood count revealed leukopenia (2.2 G/l) and thrombocytopenia (135 G/l; OKT4/OKT8 ratio was 0.08; CSF: normal; sputum culture evidenced the presence of pneumocystis carinii; EEG were normal. Neuropsychological symptoms concerned in particular a lack of concentration during the different tests with a definitive wavering of attention. Lexical retrieval was poor whatever the topic proposed.(ABSTRACT TRUNCATED AT 250 WORDS)
