The aim of this study was to review six nurse-rating schedules to evaluate their suitability for a British psychiatric unit and current nursing practice. They were compared for their reliability, their concordance with psychiatric ratings and their acceptability to the nursing staff. It was found that psychiatric and nursing observations corresponded over a wide area of psychopathology: anxiety, tension, depression, hostility, preoccupation with hypochondriacal, grandiose and self-depreciatory ideas, hallucinosis, thought disorders, mannerisms, retardation, emotional withdrawal, hypomanic activity and uncooperative behaviour. These were adequately covered by two of the scales, the Brief Psychiatric Rating Scale (BPRS) and the Psychotic Inpatient Profile (PIP), which together took 7 1/2 minutes to complete. Another of the schedules studied, the Nursing Rating Scale (Hargreaves), also had relatively high reliability and a broad effective range.

ET-495, a putative central dopamine receptor stimulant, was givem to endogenously depressed individuals, all of whom were largely unresponsive to previous drug treatment. The drug exhibited a rapid and, in some cases, a pronounced antidepressant effect. This effect was short-lived, however, and, within a brief period, depression returned accompanied by a consistent syndrome of anger, irritability, hostility and poor temper control. In one individual with a bipolar history, the induction of a paranoid psychosis and auditory hallucinosis occurred. While the data suggests a role for dopamine in the symptomatic relief of depression in man, they also imply that this monoamine cannot, in and of itself, be considered as the primum movens in either the action of other (established) antidepressant drugs, or as underlying depressive illness.

Four cases of baclofen intoxication are reported, with a review of 33 cases from the literature. Analysis of these 37 cases suggests that there are two types of baclofen intoxication syndrome. Patients with acute intoxication present with four major clinical manifestations: encephalopathy (disturbance of consciousness and/or seizure), respiratory depression, muscular hypotonia, and generalized hyporeflexia. Patients with chronic intoxication present with hallucinosis, impaired memory, catatonia, or acute mania. The acute intoxication syndrome has a faster onset, shorter duration, more severe clinical manifestations, and higher incidence of seizures than the chronic intoxication syndrome. Baclofen intoxication, although it may cause grave encephalopathic manifestations and electroencephalographic findings, has a benign outcome if actively managed.

A 74-year-old woman with a history of cerebrovascular disease developed profound central nervous system (CNS) and respiratory depression, generalized hypotonia, sinus bradycardia, and urinary retention following an increase in dose of baclofen, an antispasticity agent. Before receiving baclofen therapy the patient had had minor urinary dysfunction associated with a remote cerebrovascular accident but no urinary retention. Cessation of baclofen therapy and the relief of the urinary obstruction improved mental status and normalized motor function within 24 hours. A withdrawal syndrome of agitation, hallucinosis, and convulsive activity persisted for eight days following discontinuation of the baclofen. Our experience suggests that patients with various forms of CNS disease states may be at risk of serious CNS depression with even small therapeutic doses of baclofen.

The clinical presentation of three patients with meningiomas at different frontal sites is described. They had been ill for 3, 25, and 43 years before the tumour was demonstrated radiologically. Apathy, incontinence, dementia, and fits were seen in association with middle and superior frontal lesions, and may be mistaken for symptoms of involutional depression or presenile cerebral atrophy. In contrast, excitement and hallucinosis were seen in association with a basal frontal lesion, and may mimic psychotic syndromes like hypomania and schizophrenia, particularly if the tumour encroaches on the third ventricle and adjacent structures. Irreversible loss of myelin and axons in the frontal areas of brain surrounding the tumour may have contributed to the clinical picture of the syndrome shown by these patients.

The psychiatric manifestations of Huntington's Disease (HD) include dementia, irritability and apathy, a major affective syndrome, and hallucinosis. The theoretical and practical utility of chorea as a focus of research interest in HD is questioned, whereas the data reviewed suggest that assessments of cognition, functional capacity and motor impairment are better correlated neuropathologically, and are better indicators of disease severity and progress than chorea. The high incidence of major affective disorders on modified DSM III criteria among HD patients (41 per cent) may be explained either as a manifestation of genetic heterogeneity within the HD phenotype or on the basis of genetic linkage between HD and manic depressive illness (MDI). This is supported by the high coincidence of HD and MDI (20 out of 23) among secondary cases of HD ascertained through probands having both disorders, indicating a strong familial clustering of the association. This implies that a young adult at risk for HD who has had episodes of severe depression has considerably more than 50 per cent likelihood of progressing to manifest HD. Although auditory hallucinations appear occasionally in patients with HD, most do not meet current criteria for schizophrenia.

Drug-induced psychiatric states occur frequently in PD. In the prelevodopa era, depression and other psychiatric disorders were described in PD, but in untreated patients psychosis was rare. Since the development of levodopa and other pharmacological treatments for PD, however, psychotic symptoms have become much more common (10-50%). In some individuals these problems can be more disabling than the motor features of PD and, as a result, pose a serious threat to the patient's ability to maintain independence. The drug-induced psychoses consist of several distinct psychiatric syndromes that can be divided broadly into those occurring on a background of a clear sensorium and those which are accompanied by confusion and clouding of consciousness. Benign organic hallucinosis is the most common of these syndromes (30%). It usually occurs on a background of a clear sensorium and may not be a particularly troublesome problem if the patient is able to retain insight into the nature of these symptoms. More disabling syndromes usually include delusional thinking that is frequently paranoid, confusion and even frank delirium. Although all these psychotic syndromes can occur in isolation, there is a tendency for mild symptoms to progress to more disabling ones if adequate and timely treatment is not instituted. Abnormal dreaming and sleep disruption often precede these difficulties by weeks to months and may provide an important early clue to their onset. The mechanisms responsible for drug-induced psychotic symptoms in PD are unknown, but dopaminergic (especially mesolimbic) and serotoninergic systems are likely to be involved. The treatment of the drug-induced psychoses in PD should be undertaken in a stepwise manner. A detailed discussion of this approach, including the use of anti-PD medication adjustment, clozapine, and other medications (neuroleptic and nonneuroleptic) and ECT is provided (see Fig. 1). Although drug-induced psychoses are the most important of the drug-induced psychiatric states, mania, anxiety, and hypersexuality may also occur. Depression is also common in PD, but it is unlikely to occur as a side effect of antiparkinsonian medications.

Musical hallucinations (MH) occurred in 7 patients (5 women and 2 men, age 58-90 yrs) with mild to severe unilateral or bilateral deafness. The hallucinations usually consisted of musical memories (childhood songs, past "hits"). They started abruptly and were identified, sometimes after a period of doubt, as hallucinations. They became "louder" in the silence and, when iterative, could be distressing. By concentrating, 3 patients could change the ongoing tune for another. Elementary (1 case) or verbal (3 cases) auditory hallucinations could be associated and, in one case, vivid visual hallucinations occurred which were not criticized. One patient suffered depression and the MH faded after antidepressive treatment. In the other cases, no psychiatric disorder was identified. Neurological examination, EEGs and brain MRI (in 5 cases) were normal in all but one case, in which MH followed seizures secondary to a left parietal metastasis. Such MH may be termed hallucinosis according to Ey's description. They share some characteristics with other hallucinatory phenomena associated with sensory deprivation, such as the Charles Bonnet syndrome and "pain memories" in phantom limbs. However, the role of deafness, the underlying central mechanisms and psychological factors are poorly understood.

Depression and hallucination are the two main psychiatric symptoms in parkinsonian patients. Depressive features in Parkinson patients are very close to those of endogenous depression, except for a relative lack of anxiety, irritability, suicidal ideations, delusions and circadian rhythm. Pharmacotherapy with antidepressants is most reliable in the treatment of parkinsonian depressives, although levodopa or other antiparkinsonian drugs may relieve a depression. Hallucinatory complications of long-term antiparkinsonian treatment appear in two types of symptoms: (1) hallucinosis type-vivid visual hallucination and illusion with clear consciousness and well-preserved orientation, and (2) delirium type-less vivid visual hallucination and illusion with disturbed orientation and confusion. Antipsychotic drugs and 'drug holiday' are recommended for the management of hallucinations as side effects of antiparkinsonian drugs.

The main objectives were to study relationships between the design of group living (GL) units and psychiatric symptoms in demented patients before, 6 months after, and 1 year after admission to GL units. The study population comprised 105 demented elderly (83 +/- 6 years), 37% with dementia of Alzheimer's type and 58% with vascular dementia. The patients were relocated by the municipal care planning team after clinical examination. An observational scale (the Organic Brain Syndrome scale) was used to assess confusional symptoms and disorientation. The physical environment was assessed by an architect using the Therapeutic Environment Screening Scale, which evaluates general design, space, lighting, noise, communication area, floor plan, and related factors. Less than 15% of the patients had no signs of dyspraxia, hallucinosis, dysphasia, or depression at admission, whereas 66% or more reported lack of vitality, aggressiveness, or restlessness. Fourteen out of 18 units had a corridor-like design (group A), one unit an L-shaped design (group B), and the others a square or H-shaped design (group C). Patients living in the B unit had less disorientation than the others at the 6-month follow-up. After 1 year, the patients in the A units had more dyspraxia, lack of vitality, and disorientation of identity. The communication areas in the units were negatively associated with "disorientation for recent memory" and "lack of vitality," adjusted for type of dementia (r = -0.13 to -0.16). The size of the activity area, indoor public rooms in square meters, was not correlated to confusional reactions and disorientation. In conclusion, a GL unit design that facilitates perception without reducing the communication area is to be preferred.
