Hypochondriacal psychoses: a long-term follow-up

Health Anxiety

Abstract. Health anxiety, characterized by excessive concern about one’s health, is a serious and costly public health problem. The disorder might become chronic if left untreated. Unfortunately many patients do not receive timely or proper treatment due to sparse treatment resources. Also, existing treatment programs, though effective for many, do not work for all. This paper discusses the conceptualization of health anxiety and future directions based on novel research findings. These include: (i) the content and characteristics of autobiographical memories and episodic future thoughts in severe health anxiety, (ii) related concepts such as cyberchondria with excessive Internet browsing on health issues and health anxiety by proxy, where parents display and might confer health anxiety towards their children, (iii) an epidemiological perspective on the association between health anxiety and subclinical psychotic experiences in preadolescence. Exploring these new dimensions could have important implications for the further development of preventive strategies and effective treatment.

Cenesthopathy in adolescence: an appraisal of diagnostic overlaps along the anxiety-hypochondriasis-psychosis spectrum

OBJECTIVE

To discuss the diagnostic validity of unusual bodily perceptions along the spectrum from age-specific, often transitory and normal, to pathological phenomena in adolescence to hypochondriasis and finally to psychosis.

METHODS

Critical literature review of the cornerstone diagnostic groups along the spectrum embracing anxiety and cenesthopathy in adolescence, hypochondriasis, and cenesthopathy and psychosis, followed by a discussion of the diagnostic overlaps along this spectrum.

RESULTS

The review highlights significant overlaps between the diagnostic cornerstones. It is apparent that adolescents with unusual bodily perceptions may conceptually qualify for more than one diagnostic group along the spectrum. To determine whether cenesthopathies in adolescence mirror emerging psychosis, a number of issues need to be considered, i.e. age and mode of onset, gender, level of functioning and drug use. The role of overvalued ideas at the border between hypochondriasis and psychosis must be considered.

CONCLUSION

As unusual bodily symptoms may in some instances meet formal psychosis risk criteria, a narrow understanding of these symptoms may lead to both inappropriate application of the new DSM-5 attenuated psychosis syndrome and of treatment selection. On the other hand, the possibility of a psychotic dimension of unusual bodily symptoms in adolescents must always be considered as most severe expression of the cenesthopathy spectrum.

Delusions of oral parasitosis

1. The authors present a case of a 76-year-old man with delusional disorders, somatic type, who strongly believed that his mouth was infested with worms. 2. Such a case has not previously been described in the literature and the authors refer to the syndrome as delusions of oral parasitosis. 3. The authors examined the effect of pimozide, whose efficacy on delusional skin parasitosis has been proven. Taking the neuroleptic at a dose of 2 mg daily relieved the symptoms.

Treatment of schizophrenia and delusional disorder in the elderly

With increasing longevity, greater numbers of patients with schizophrenia and delusional disorder will be surviving into advanced age. Antipsychotics form the core of the treatment for both of these psychotic disorders. Treatment of elderly patients with antipsychotics is, however, complicated by a much higher risk of adverse effects such as tardive dyskinesia. More is known about treating patients with schizophrenia than those with delusional disorder. The introduction of newer atypical antipsychotics may herald a new era in the pharmacotherapy of elderly psychotic patients. Nonetheless, judicious dosing is essential in the geriatric population. We discuss the benefits and limitations of the main forms of treatment.

Monosymptomatic hypochondriacal psychosis in a man with learning disabilities

A case report of a male patient with moderate degree of learning disabilities and monosymptomatic hypochondriacal psychosis is described, along with its pathogenic features and response to treatment.

Late-onset psychosis with somatic delusions

The authors studied 10 patients who had late-onset psychosis with somatic delusions and 2 comparison groups similar in age and education: 9 late-onset psychosis patients without somatic delusions and 10 normal control subjects. Demographic, clinical, and neuropsychological data were obtained. Brain magnetic resonance imaging was also done and compared. The patients with somatic delusions were somewhat more likely to be women, have been ill longer, and meet DSM-III-R criteria for delusional disorder, compared with late-onset psychotic patients without somatic delusions. Patients with somatic delusions also had lower scores on a full-scale IQ test, compared with the normal comparison subjects. The patients with somatic delusions rarely benefitted from and poorly complied with treatment with psychotropics. The study's limitations, such as small sample size and heterogeneity of diagnosis, as well as the possible clinical implications of these findings are also discussed.

Three thousand days of pregnancy. A case of monosymptomatic delusional pseudocyesis responding to pimozide

An unusual case of pseudocyesis of almost ten-year duration, characterised by a monosymptomatic hypochondriacal delusion and a selective response to pimozide is reported. The nosological status of the diagnosis, delusional (paranoid) disorder, is suggested to be a variety of the Kraepelinian concept of paranoia. The therapeutic pitfalls of relying on a phenomenological distinction between overvalued ideas and delusional beliefs are discussed.

Delusional disorders. I. Comparative long-term outcome

Of 301 first-admitted patients with delusional psychoses, 94 met DSM-III criteria of schizophrenia (S), 53 paranoid disorder (PD), 47 schizophreniform disorder (SFD), 35 schizoaffective disorder (SAD), 54 major affective disorder (AD), and 18 other disorders (OD). Retterstöl selected the patients and personally interviewed them after 5-18 years, and later the author interviewed them after 22-39 (mean 30) years. At last follow-up good functioning was noticed in 42%, moderate symptoms in 22%, severe defect in 20%, and very severe defect in 16%; 40% were still delusional. On average S patients did poorest, and OD patients slightly better. AD patients had superior outcome, while PD, SFD and SAD patients showed an intermediate position, but a little closer to AD than to S. However, heterogeneous course and outcome was noticed in all diagnostic groups.

Long-term course and outcome in unipolar affective and schizoaffective psychoses

Of 301 first-time admitted patients with delusional psychoses, 50 met DSM-III criteria for major depressive disorder (MDD), 33 schizoaffective disorder, depressive type (SADD), and 94 schizophrenia. At personal follow-up after 3-39 (mean 22) years, the SADD group was recorded in between on course and outcome variables, but closer to MDD. The findings in MDD and SADD were respectively: remission 66% vs. 42%, personality disorders 14% vs. 12%, anxiety disorder or alcohol abuse 2% vs. 6%, psychosis 18% vs. 36% (with bipolar development in 2% vs. 6%, paranoid disorder 2% vs. 3%, schizophrenia 4% vs. 3%). Chronic psychosis was recorded in 10% vs. 27%. No significant outcome difference was found between early onset MDD and SADD cases and those who fell ill at a higher age. The assumption that antidepressants may induce mania could not be confirmed. Normal premorbid personality seemed to predict a favourable course.

Long-term course and outcome in delusional disorder

Out of 301 first-time admitted patients with delusional psychoses, 71 met Kendler's criteria of delusional disorder (DD) and 137 met the ICD-9 criteria of schizophrenia (S). DD was subdivided according to operational criteria into reactive delusional disorder (RDD) with precipitating factors (n = 31) and non-RDD (n = 40). At follow-up after 22-39 years, 20 RDD patients, 21 non-RDD patients and 85 S patients were personally interviewed. The delusions had faded in 61% of DD cases, were unchanged in 17%, and more prominent in another 17%. Recovery was recorded in 37%, mild defect in 32%, moderate impairment in 10%, and severe impairment in 22% of DD patients. Outcome was more favourable in DD compared with S, in RDD compared with non-RDD, and in non-RDD compared with S. The study supports distinctions between DD and S, RDD and non-RDD, and non-RDD and S based on course and outcome.
