The treatment of hysterical blindness by behavior therapy

The inpatient treatment of patients suffering from (motor) conversion symptoms: a description of eight cases

This article presents a preliminary study that used two controlled randomized trials to study the effect of hypnosis in the treatment of eight patients with (motor) conversion symptoms. Controlled research into the treatment of conversion symptoms is scarce and can often be criticized on methodological grounds. It would appear, however, that both the use of suggestive and behavioral therapeutic techniques and eclectic treatment programs yield good results in the treatment of conversion symptoms. The results of the study suggest that comprehensive clinical treatment including hypnosis has enough promise to be studied in clinical trials. In the interpretation of the results, special attention is given to primary diagnosis, duration of complaints, traumatic experiences in childhood, dissociative capacity, and hypnotizability.

Hysterical symptoms in ophthalmology

Ophthalmologic symptoms are often not sufficiently accounted for by organic pathology. The complaints of these patients have been labeled hysterical, psychogenic, non-organic, or functional. The psychiatric nosology in this area may be the most confusing in the whole field of clinical medicine. The Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R) offers a classification designed to reduce non-empirical concepts and ideology to a minimum. On this background, we discuss the hysterical symptoms encountered in clinical ophthalmology with special emphasis on psychogenic amblyopia and blepharospasm. Motor symptoms are commonly not of psychogenic origin. It is suggested that ophthalmologists are most likely to treat patients with psychogenic symptoms, using suggestion, patience, and reassurance. Few patients require psychiatric consultation and a specific psychiatric therapy. The association of hysteria with organic brain disease and the issue of symptom lateralization are briefly discussed. Eventually, we reject the psychoanalytic approach and suggest that the concept of abnormal illness behavior and the neurobiological models involving corticofugal inhibition, primitive reflex mechanisms, and an attention disturbance, serve best to understand the nature of the phenomenon hysteria.

Behavioral rehabilitation of functional alexia

A 10-year-old boy with a functional reading deficit (i.e. functional alexia) was successfully treated with hospital based escape/avoidance procedures. A multiple baseline design was used to evaluate the effectiveness of treatment. Generalization of treatment effects across individuals, settings and time was demonstrated. Extension of these procedures to other functional deficits is discussed.

Functional visual loss: I. A true psychiatric disorder?

A review of the literature describing patients with functional visual loss reveals that a significant proportion of them do not manifest psychiatric disease as defined by current nomenclature. Apparently, these individuals are highly suggestible and do not necessarily have psychological pathology. The ramifications of this finding are discussed.
