Extract

Classical cases of catatonia in schizophrenia have become much less frequent with the introduction of neuroleptic drugs (Blumer, 1997), and psychiatrists practising in Western countries may well have seen few cases. Neuroleptic malignant syndrome (NMS), however, continues to occur in between 0.02% and 0.4% of patients and may occasionally prove fatal (Addonizio et al, 1986). We report a case with features of both these conditions.

Classical cases of catatonia in schizophrenia have become much less frequent with the introduction of neuroleptic drugs (Reference BlumerBlumer, 1997), and psychiatrists practising in Western countries may well have seen few cases. Neuroleptic malignant syndrome (NMS), however, continues to occur in between 0.02% and 0.4% of patients and may occasionally prove fatal (Reference Addonizio, Susman and RothAddonizio et al, 1986). We report a case with features of both these conditions.

Case history

The patient, 51 years old, was first admitted to hospital in 1966 at age 19. He was noted to have a “fear of death” and “increased sexual desire”, and a “very abnormal electroencephalogram” and an encephalopathy resembling leucoencephalitis was suggested. Since childhood the patient was said to have had “tics and mannerisms”.

A diagnosis of schizophrenia was made in 1967, when he was 20 years of age, and he has needed over 14 further admissions presenting with a number of delusions. He has been an in-patient continuously since 1986, when he was aged 39. Over the years a wide range of antipsychotic medication (including chlorpromazine, thioridazine, trifluoperazine, perphenazine, haloperidol, fluphenazine and benperidol) has been required, often in substantial doses.

In recent times he has suffered persistent, though variable, symptoms of psychosis, stereotypies, mannerisms, evidence of tardive dyskinesia and possible torsion dystonia. His drug treatment prior to this exacerbation consisted of fluphenazine decanoate depot, oral benperidol and diazepam.

A dramatic change in his condition occurred in October 1998. He became restless and self-care worsened. He heard voices from God about damnation, and felt guilty and worthless. He felt he might soon die. He felt thoughts inserted into his mind, and experienced the feeling of being pushed against the walls. Over 10 days he needed a total dose of 650 mg of zuclopenthixol acetate intramuscular, with additional droperidol and diazepam as required. He had a number of bruises from falling and the need for restraint. His creatinine kinase level was raised at 4960 iu/l, as was the neutrophil count; heart rate was 116 per minute. He suffered periods of screaming and apparent rigidity.

Transfer to the adjacent general medical unit was undertaken. He remained ill, and very distressed. He was sweating markedly and blood pressure was labile. His limbs became increasingly rigid, and attempted movement was very painful. For a time he was unresponsive, moving only his eyes. Temperatures spiked, up to 38.9 °C, and respiration was impaired. Cortisol levels were raised. Analysis of the raised creatinine kinase level showed it to be of muscle rather than cardiac origin. An Escherichia coli urinary infection was identified and treated. A lumbar puncture was undertaken, but the cerebrospinal fluid was normal. Computerised tomograms of the head were also normal. Benzodiazepines and anticholinergic medication were required on a number of occasions.

The patient, however, remained significantly distressed and delusional and required electroconvulsive therapy (ECT). He improved swiftly and substantially, returning to his state of health prior to this exacerbation. He was prescribed risperidone, and for the emergence of affective features, lithium was added. Following a relapse requiring further ECT, clozapine was started — and valproate later added following an epileptic fit. He has also required low dose thioridazine and diazepam. However, he is currently fairly well, with no active psychoses or affective symptoms.

Discussion

Catatonia was first described by Kahlbaum in 1874 (Reference Kahlbaum, Levij and PridanKahlbaum, 1973). It is seen in affective and schizophrenia disorders, and is characterised by abnormalities of movement including posturing, stereotypies and waxy flexibility. Language abnormalities may also be present and include echolalia and verbigeration (Reference Murray, Hill and McguffinMurray et al, 1997). In the past chronic catatonia states were common sequelae of encephalitis lethargica; now that this is no longer epidemic, catatonia has lessened in frequency in psychiatric hospitals (Reference JohnsonJohnson, 1993), but is still reported to occur with regularity in district hospital units. Treatment is to avoid neuroleptics, possibly prescribe benzodiazepines and ECT is of value.

The NMS was first described in the English language literature by Reference Delay, Deniker, Vinken and BruynDelay and Deniker in 1968. The onset is some 2-28 days after receiving neuroleptics. Muscular rigidity, akinesia, pyrexia, clouding of consciousness and autonomic changes may be present — the latter including hypertension, sweating, pallor and urinary incontinence; there may be a neutrophilia, raised creatinine phosphokinase (CPK; an enzyme released in muscle damage) and raised potassium levels (Reference Murray, Hill and McguffinMurray et al, 1997).

It may last 5-10 days after drug discontinuation, but longer with depot preparations. There is no treatment proven to be effective, but bromocriptine and dantrolene have been used. It has been more recently suggested that CPK levels are raised in catatonic patients, and this is related to dyskinetic movements (Reference Northoff, Wenke and PflugNorthoff et al, 1996). The coexisting E. coli urinary tract infection from which this patient suffered did complicate the clinical picture, and may have contributed to the pyrexia and neutrophilia.

Forty years ago, here in Dumfries, Mayer-Gross, in a text influential in its time, drew attention to coexisting physical illnesses: he felt that they were the immediate cause of death in such cases, and the patients' abnormal behaviour impeded their diagnosis (Reference Mayer-Gross, Slater and RothMayer-Gross et al, 1960; Reference KellamKellam, 1987). Again, more recently, it has been suggested that NMS is not an unitary syndrome, but could represent extrapyramidal side-effects (EPS) complicated by medical disorders — with dehydration, infection, pulmonary embolism and rhabdomyolysis being common complications of untreated EPS (Reference Levinson and SimpsonLevinson & Simpson, 1986). Features common to both catatonia and NMS are increasingly recognised, with the NMS felt to closely represent advanced catatonia; similar syndromes with unexplained fulminating hyperpyrexia, usually in the setting of catatonia, have been noted since the beginning of the 19th century, well before the development of neuroleptics (Reference KellamKellam, 1987). A common neurochemical basis has been postulated for catatonia and NMS: a massive blockade of dopamine receptors, previously hyper-stimulated by psychoses or by dopamine blocking drugs (Reference Osman and KhurasaniOsman & Khurasani, 1994), and both share a common beneficial response to ECT. Patients with past or present catatonic symptoms are particularly vulnerable to NMS (Reference BlumerBlumer, 1997).

This is a complex and partially understood area, but one that deserves a high level of awareness both owing to the morbidity and mortality that may occur, and to the fact that treatment may be effective. While some literature suggests that lethal catatonia often requires neuroleptic treatment (Reference Castillo, Rubin and Holsboer-TrachslerCastillo et al, 1989), it is more widely held that, as mentioned in a review article: “Although the mental blockade effected by routine early prescription of neuroleptics appears to prevent emergence of the previously plentiful catatonic symptoms in schizophrenia, once catatonic signs are already present the neuroleptics must be avoided because of the risk of severe catatonia with NMS. For the same reason, neuroleptics should be prescribed with caution for patients with a history of catatonia.” (Reference BlumerBlumer, 1997)

This patient had no history of catatonia, but there is the possibility of one of a movement disorder, and more recently he had suffered from a degree of tardive dyskinesia. Conversely, this patient did have frequent symptoms of psychoses over recent years requiring active treatment. Clozapine, which this patient is now receiving, has been shown to be of value after an episode of NMS (Reference Weller and KornhuberWeller & Kornhuber, 1992). However, atypical antipsychotics including clozapine, olanzapine and risperidone may also cause NMS and catatonia. Clozapine is not available on the Japanese market owing to reports of malignant hyperthermia.

Despite the decline in the prevalence of classical catatonia, we should remain alert to it, and to NMS. While remaining aware of the benefits that traditional neuroleptics have brought, and their continuing value as part of a package of treatment in the emergency situation, we must continue to use them with caution. When catatonia does occur, a prompt response and liaison between psychiatrists and physicians is essential.
