Delirium is reported to be a common problem in terminally ill patients. The poor prognosis given to these patients may result in the failure to recognize the causes that are easily treated and may be reversible. We present four patients in whom a comprehensive assessment revealed a number of reversible causes of delirium, resulting in a treatment approach that significantly improved the patients' cognition and quality of life.

This article outlines the approach to the management of delirium developed by the staff of the palliative care unit at the Edmonton General Hospital. Delirium occurs commonly in the terminally ill and is associated with a poor prognosis. Management requires a clear understanding of what delirium is, how to assess it, investigations for reversible causes, and the medical treatments that are most useful. If not well managed, delirium can be a very distressing symptom for the patient and family as well as having a very destructive impact on the functioning of a palliative care unit.
Ten patients with the stable syndrome of hysteria were matched for age, sex, handedness, and full-scale WAIS IQ with ten controls, ten psychotic depressives and ten schizophrenics. All were subjected to an extensive neuropsychological test battery. Compared to the controls, the hysteria group exhibited bifrontal impairment (R = L) and, globally, greater dysfunction of the nondominant hemisphere. A G analysis provided a complete separation between the hysteria and controls. However, a D-index analysis showed that the hysteria group was more impaired than normals and depressives because of greater dysfunction of the dominant hemisphere, whilst schizophrenia showed greater nondominant hemisphere dysfunction than hysteria. Further, a cluster analysis on the 40 subjects produced three clusters: normal controls, depressives, and a schizophrenia-hysteria grouping. These findings are interpreted as suggesting that dominant hemisphere dysfunction is fundamentally related to the syndrome of hysteria and that the dysfunction of the nondominant hemisphere is brought about by associated features: the female excess, the emotional instability and dysphoric mood, the presence of asymmetrical pain, and conversion symptomatology. It is further argued, in view of the familial associations, that hysteria in the female is a syndrome equivalent to psychopathy in the male (who also exhibits dominant hemisphere dysfunction) and might represent in the female a (relatively benign) variant of schizophrenia characterized by imprecise verbal communications, a subtle form of affective incongruity, together with the conversion parameter.
