The Nithsdale schizophrenia surveys. An overview.

The Nithsdale surveys over a ten year period have examined a community of schizophrenic patients. Although almost three-quarters of patients were living outside hospital, social and psychiatric disability was considerable, with flattening of affect and social withdrawal most prominent. The majority probably cause little disturbance to most people in the community. Only 13% of the total Nithsdale schizophrenic population were living in a high contact/high Expressed Emotion family, the family structure believed to be most conducive to schizophrenic relapse. An attempt at family intervention found it difficult to engage relatives in treatment; however, where such intervention did take place, there was a fall in the total number of relapses. Reassessment found that the level of EE was stable in most relatives over a five year period. Patients who lived in a high or fluctuating EE home, and who relapsed, did so more often than those who lived in a low EE home. Assessment of the prevalence of motor disorders secondary to antipsychotic medication found a point prevalence of parkinsonism of 27%, of tardive dyskinesia (TD) 29%, and of akathisia or pseudoakathisia 23%. Only 44% had no movement disorder. Eight percent had persistent TD. Parkinsonism was associated with a history of obstetric complications and TD with left-handedness. An obstetric history obtained from mothers of schizophrenic patients found there was no difference in the proportion of schizophrenic patients and their sibs who had at least one definite obstetric complication.

Psychosocial family intervention in schizophrenia: a review of empirical studies.

"This paper reviews the recent empirical studies on psychosocial family intervention in schizophrenia. Six family educational intervention studies and five more intensive family work studies with 2-year follow-up have been included. A series of questions is asked relating to the effects of such interventions, the efficacy of the different educational models, the active ingredients of these multi-component treatment packages, and the contribution of this new generation of studies to our understanding of the mechanisms through which these interventions work. Suggestions for further research are made. Finally, from the published manuals, the common components of these diverse, multi-component treatment packages of different family-intervention studies are identified."

The Nithsdale schizophrenia surveys. IX: Akathisia, parkinsonism, tardive dyskinesia and plasma neuroleptic levels.

Of all known schizophrenics living in Nithsdale, south-west Scotland, 146 (88%) were examined for the presence of the three principal movement disorders secondary to antipsychotic medication, namely akathisia, tardive dyskinesia and Parkinsonism. Of these, 18% had akathisia, 5% pseudoakathisia, 29% tardive dyskinesia, 8% persistent tardive dyskinesia, and 27% Parkinsonism. No movement disorder was seen in 445, 36% had one and 20% had more than one movement disorder. Plasma neuroleptic levels at the time of clinical assessment were measured by the radioreceptor technique. Correlations between dose and plasma level were low; the ratio of mean plasma concentration to mean dose was greatest with fluphenazine decanoate and lowest for sulpiride. The concentration:dose ratio was higher in the elderly. There was no relationship between neuroleptic levels and akathisia, Parkinsonism or tardive dyskinesia. Additional psychotropic medication influenced neuroleptic levels. In 9% of patients receiving oral antipsychotic medication, no drug was detected in plasma.

The Nithsdale schizophrenia surveys. X: Obstetric complications, family history and abnormal movements.

Obstetric histories of 54 schizophrenic patients and 114 siblings were obtained from their mothers and scored using the Obstetric Complications Scale. There were no statistically significant difference in the proportion of schizophrenic patients (35%) and siblings (29%) who had at least one definite obstetric complication. There was no evidence that schizophrenic patients with a history of obstetric complications were less likely to have a first-degree relative with a history of psychiatric illness leading to in-patient care. Schizophrenic patients with a history of obstetric complications were more likely to have drug-induced Parkinsonism. There was a trend for tardive dyskinesia to be more common in those schizophrenic patients with no obstetric complications but a family history of schizophrenia.

The Nithsdale schizophrenia surveys. VIII: Do relatives want family intervention--and does it help?

Sixty-three relatives of 52 schizophrenics living at home were offered a package of treatments by professionals working in an everyday NHS setting: educational seminars, relatives' groups, and family meetings. Thirty-two relatives refused intervention. Of the 31 relatives who agreed, 14 attended neither the educational seminars nor the relatives' groups. Seventeen relatives had a mean of ten treatment sessions, but there was little change in their level of expressed emotion after intervention. The number of patients who relapsed was the same in the 18 months before and after intervention, although the total number of relapses fell after intervention.

The Scottish survey of old long-stay in-patients.

A total of 2605 old long-stay patients, defined as those admitted to hospital before the age of 65 years and in hospital more than six years, were identified in psychiatric hospitals serving 83% of the Scottish population. The bed occupancy was 59 per 100,000 of the general population, with a range among hospitals of 19-123 per 100,000. Of all patients, 64% were schizophrenic and 15% had organic brain disease; most patients were male, single and over 60 years of age; 41% had been in hospital more than 30 years; 61% had either florid psychotic symptoms or symptoms of a deficit state in marked or severe degree, and the rehabilitation potential for 70% was low. An increasing prevalence of deficit symptoms in schizophrenics was associated with increasing length of stay in hospital; the difference was most marked between those admitted before and after 1953.

Pharmacokinetics of haloperidol and fluphenazine decanoates in chronic schizophrenia.

In a double-blind comparison of haloperidol decanoate and fluphenazine decanoate given 4-weekly for 60 weeks as maintenance therapy in 38 chronic schizophrenic in-patients, plasma haloperidol, fluphenazine and prolactin levels were measured at regular intervals by radioimmunoassay. After the first injection, the mean plasma haloperidol level was highest at week 1 and fell gradually towards week 4. Mean pre-dose haloperidol levels changed little after week 8. Results suggested an absorption half-life of 4 weeks, although, in three cases steady state was only achieved after 11 monthly injections. Steady state levels of both haloperidol and fluphenazine correlated highly with dose. In two sub-groups observed at steady state, both drugs produced a biphasic pattern of plasma drug concentration between injections, a rapid rise on day 1 followed by stable elevated levels and a gradual return to pre-injection concentration by the end of week 4. In the fluphenazine sub-group there was a second peak on day 7 and a steeper decline, so that the mean area-under-curve in week 4 was 64% of that in week 1. Drug injections at steady state induced an increase in prolactin secretion in all of the fluphenazine sub-group and in half of those receiving haloperidol. Plasma prolactin changes resembled those for drug concentrations, but differences in times of peaks on day 1 resulted in weak correlations. Fluphenazine appeared more potent than haloperidol in provoking prolactin secretion.

A double-blind comparative study of remoxipride and thioridazine in the acute phase of schizophrenia.

Sixty-one patients with acute schizophrenia received either remoxipride (75-375 mg daily) or thioridazine (150-750 mg daily) for 6 weeks. There was no statistically significant between-drug difference in improvement in mental state, as measured by the Brief Psychiatric Rating Scale, although the trend favoured thioridazine; global assessment of illness severity at the last rating also favoured thioridazine. Sedation, anticholinergic effects, autonomic dysfunction, and weight gain were significantly more common in patients receiving thioridazine. Both drugs produced few extrapyramidal effects, but both were associated with cardiovascular changes in two patients; neither drug produced significant abnormalities in laboratory tests.

The Scottish first episode schizophrenia study. VII. Two-year follow-up. Scottish Schizophrenia Research Group.

Of 49 schizophrenic patients followed up 2 years after their first admission to hospital, 37% were well, 47% had been readmitted to hospital at some time over the 2 years, and 38% showed schizophrenic symptoms at follow-up. A poor outcome at 2 years was associated with male sex, poor outcome after the first 5 weeks of the first admission, negative schizophrenic symptoms on first admission, and a diagnosis of definite or probable schizophrenia using the Feighner criteria. Only 23% were in employment. A small double-blind discontinuation study of maintenance antipsychotic medication during the second year found more relapses in those switched to placebo medication. Repeat psychometric assessment at 2 years confirmed modest improvements found at 12 months; that is, there was no evidence of intellectual decline. Relatives showed no more psychosocial distress than that found in a normal community sample; what distress there was correlated with patients' schizophrenic symptoms.

Is electroencephalographic monitoring of electroconvulsive therapy clinically useful?

Electroencephalographic (EEG) monitoring was carried out in 169 bilateral and 114 unilateral applications of electroconvulsive therapy (ECT), given to 51 patients in an everyday setting within the National Health Service by junior medical staff. In 2.5% of bilateral and 8% of unilateral applications there was disagreement between clinical and EEG assessment as to whether a fit had occurred. When an EEG fit was said to have occurred only if it lasted longer than 25 seconds, then disagreement rose to 7% in bilateral and 28% in unilateral applications; disagreement was higher with unilateral applications, as they produced more short fits than bilateral applications. If future work shows duration of seizure is clearly associated with clinical efficacy, it is suggested the case for routine EEG monitoring is greatly strengthened.

Comments on the Northwick Park 'Functional' Psychosis Study.

"Functional psychosis is conventionally subdivided into schizophrenia and manic depressive psychosis. Response to treatment is assumed to be a validating criterion for these diagnoses. The efficacy of pimozide (a dopamine antagonist neuroleptic), lithium, and a combination of the two was compared with that of placebo in a 4-week trial in 120 functionally psychotic patients, each of whom was assessed for psychotic symptoms, manic symptoms, and depressive symptoms. The sample was subdivided into patients with predominantly elevated mood, predominantly depressed mood, and no consistent mood change. Pimozide reduced psychotic symptoms in all groups of patients. The only significant effect of lithium was to reduce elevated mood. Thus dopamine blockade seems relevant to the resolution of psychotic symptoms in all types of 'functional' psychosis, but the mode of action of lithium in psychotic patients concerns only mood. Application of standardised classifications of functional psychosis to these data did not change this conclusion."

The Scottish survey of new chronic in-patients: five-year follow-up.

Patients aged 18-64 years, in hospital more than one but less than six years, were followed up five years after identification: 22% had died, 50% remained in-patients, and 28% had been discharged; only 10% of first admissions with organic brain disease had left hospital. Of those discharged, 37% had no contact with after-care services. Of those remaining in hospital, 39% did not require in-patient care. Patients' level of functioning had improved over the five years.

The operation of the Mental Health (Scotland) Act 1984 in one psychiatric hospital.

The Mental Welfare Commission for Scotland has commented on tentative evidence of the increasing use of compulsory detention in Scotland. Findings at Crichton Royal Hospital, Dumfries show that the number of patients detained annually has changed little since the introduction of the Mental Health (Scotland) Act 1984, but that more patients are being transferred from emergency to further detention, and that the average length of detention has risen sharply, with almost a half being detained for more than 28 days. The question is posed: are Scottish patients being well served by the Act--and by Scottish psychiatrists?

A double blind comparative study of remoxipride and thioridazine in the acute phase of schizophrenia.

This is the first comparative double blind study of remoxipride. Sixty-one patients with acute schizophrenia received either remoxipride (75-375 mg daily) or thioridazine (150-750 mg daily) for 6 weeks. There was no statistically significant between-drug difference in improvement in mental state, as measured by the Brief Psychiatric Rating Scale, although the trend favoured thioridazine; global assessment of illness severity at the last rating also favoured thioridazine. Sedation, anticholinergic effects, autonomic dysfunction and weight gain were significantly more common in patients receiving thioridazine. Both drugs produced few extrapyramidal effects, but both produced cardiovascular changes in two patients; neither drug produced significant abnormalities in laboratory tests.

The Nithsdale Schizophrenia Survey. VII. Does relatives' high expressed emotion predict relapse?

A review of all known schizophrenic people living in Nithsdale in South-West Scotland identified long-stay in-patients, patients living on their own and those living with relatives showing low or high expressed emotion (EE). A prospective 12-month follow-up identified relapsing patients, defined as those readmitted to hospital with exacerbation of schizophrenic symptoms or a fresh episode of illness, or, if not readmitted, with a significant increase in antipsychotic medication. There was no difference in relapse rates in patients living on their own, with low-EE, or with high-EE relatives. Amount of contact with high-EE relatives did not affect relapse rates. The different results obtained from the Nithsdale group compared with one from Camberwell are discussed.

Scottish survey of chronically ill day patients: 3-year follow-up.

Chronically ill day patients were followed up 3 years after identification in the catchment areas of 13 psychiatric hospitals serving 54% of the Scottish population. Five per cent had died, 6% were in-patients, 56% remained day patients and 14% were supported by community psychiatric nurses or attended an out-patient clinic; contact had been lost with 19%. Over 3 years, 32% had had at least one admission to in-patient care; a wide range of other services was also used. There was little change in the level of disability; a typical patient in contact at follow-up was single, schizophrenic, and rather disabled.
