Course and prognosis of the syndrome of doubles.

The course and prognosis of 20 patients with the syndrome of doubles (syndrome of Capgras, syndrome of Frégoli, syndrome of intermetamorphosis, syndrome of subjective doubles) were studied. The onset of the syndrome occurred either synchronously or at a later stage than the onset of the associated psychosis. The syndrome failed to remit in seven of the 20 cases, and in the others remission occurred either synchronously with or later than the remission of the basic psychosis. In all cases of depression, the syndrome cleared shortly after remission of the depressive illness. It was, however, more persistent than the accompanying psychosis in the schizophrenic patients with the Capgras variety. Relapse of the basic psychotic condition in the setting of which the syndrome had originally developed was invariably accompanied by reappearance of the syndrome.

Stereopsis and unilateral brain disease.

Performance on a random-letter stereoscopic task has been reported to be affected by right but not left cerebral disease. Subsequent studies employing a conventional stereoacuity test have challenged these results and proposed that dementia may be the primary determinant of impaired stereopsis in the patients with brain disease. The latter investigators have failed to distinguish between local and global stereopsis. The present study confirms the original findings, rules out dementia as a potential artifact, and attempts to reconcile the conflicting series of reports.

[Visual perception disorders in depressive syndromes].

A wide range of psychopathological visual phenomena, part of which are traditionally considered as derealizational disturbances, are described in the structure of depressive states. Five main types of disordered visual perception are singled out, which differ by their structure and degree of correlation with the depressive affect and symptoms of depersonalization in a wide sense. The results point to certain dynamics in the described phenomena, their sensory basis. Electrooculographic studies of eye movements indicating a peculiar formation of a visual image in different forms of depressions are demonstrated.

[An atypical case of subacute sclerosing panencephalitis (SSPE), (with special reference to psychiatric and psychological evaluations)].

An atypical case of subacute sclerosing panencephalitis is described, with particular reference to its psychiatric and psychological aspects in the light of the neurological and laboratory data: slow-gamma electrophoresis of the spinal fluid, periodic delta signs in the EEG over about 6 yr, 1/160 blood titre of anti-measles virus antibodies. The history displayed an ingravescent dementia course and the patient's continuing survival for more than 11 yr makes the case the longest recorded in the literature. Both the psychiatric-psychological and neurological symptoms had occurred in distinct stages. It is suggested that neurological recrudescence was responsible for the pattern of symptomatological stabilisation followed by sudden relapses. The symptoms regarded as characteristic of the terminal stage have not yet appeared, especially on the neurological side.

The use of masking level differences in the identification of children with perceptual problems.

The purpose of this investigation was to determine whether masking level differences (MLD's) could differentiate between normal children and children with suspected auditory processing problems. MLD's for speech and 500-Hz tones were measured for an experimental group consisting of 24 normal-hearing children suspected of having auditory perceptual dysfunction. Fourteen children with normal auditory processing abilities and 11 normal-hearing adults comprised the control groups. Results indicated that (1) there was no difference between MLD's for "normal" children and normal adults; (2) there was no difference between speech MLD's for the two groups of children; however, (3) tonal MLD's for the children with suspected auditory perceptual problems were significantly lower than those for the normal groups. Using a cut-off tonal MLD of 7 dB, 79% of the experimental group were positively identified whereas only 12% of the normals were identified. The tonal MLD can be a strong addition to a central test battery, especially because it can be used with nonverbal children who cannot complete many tests because of limited linguistic skills.

[Complaints of memory loss in the elderly].

Frequency of memory complaints increases with age. Such complaints can be the presenting symptom of Alzheimer's disease. Most cases, however, are not related to Alzheimer's disease. They are included in the constructs of benign senescent forgetfulness or age-associated memory impairment. In the later, memory complaints are considered as the subjective counterpart of the age-associated decline in memory test performance. Actually, memory complaints are associated with various factors: perceptual disorders, general health, functional disability, affective disturbances, psychosocial changes... The first step in the management of memory complaints is to rule out Alzheimer's disease and affective disturbances which could require specific therapeutic measures. Most often, memory complaints are the only presenting symptom: the signification of complaints should be analysed in each individual considering all the possibly causal factors in order to elaborate the appropriate management.

[Pseudo-hallucinations after long-term lithium treatment].

A 58-year old women with a history of recurrent depressive episodes had been on successful prophylaxis with lithium carbonate in controlled therapeutic dosage for 11 years. At this time she experienced with increasing frequency mostly visual, sometimes auditory pseudohallucinations which disappeared after stopping the lithium medication. Because a subsequent depressive episode did not respond to tricyclic antidepressants or to a MAO-inhibitor the patient was again prescribed lithium. At therapeutic lithium blood levels the previous perceptual disorders then returned.
