The effect of artificially varying the pupil size upon the pattern evoked visual response was examined in six healthy subjects and six patients with multiple sclerosis who had abnormal visual evoked responses. Slight depression of amplitude was seen whether the pupil was small or large, but the most obvious effect was a reduction of latency with a large pupil and an increase of latency with a small pupil. It is suggested these phenomena relate to the amount of light entering the eye and not any change of acuity.

The findings concerning the basic psychic condition preceding the onset of a so-called multiple sclerosis seem to correspond to the basic structure and disorders of a narcissistic neurosis, especially that of the phobic type of this illness. The same psychic structure may also be referred to as faulty identify establishment or, in terms of depression, described as a somatically masked depression. Because of the deep-rooted psychic damage lasting results can only be obtained by long-term uncovering analytic psychotherapy. In general patients afflicted with a neurosis of this type violently oppose to psychic training and reorientation.

Some multiple sclerosis patients with 20/20 acuity complain of poor vision. In a previous report we accounted for this in our patient group by showing that multiple sclerosis had caused a depression of contrast sensitivity while sparing visual acuity. In this study we investigated whether some of this measured depression might be due to abnormally rapid or severe adaptation during the test procedure rather than a true permanent loss. Our finding was opposite to this supposition: adaptation was normally slight and/or slow. Depressed contrast sensitivity was not well correlated with abnormal adaptation to contrast. In patients whose contrast sensitivity losses were restricted to a band of spatial frequencies, we found no evidence that abnormalities of contrast adaptation were restricted to this same spatial frequency band. Further evidence of dissociation between abnormal contrast sensitivity and abnormal contrast adaptation is that some patients with normal contrast sensitivity showed abnormally small adaptation.

A report is given on 82 patients suffering from multiple sclerosis (MS) who were treated over a period of up to a maximum of eight years - average treatment 4-6 years. The best results were found in patients passing through an acute episode. Among the chronic-progressive cases, 5.1 per cent of the patients showed an improvement. In 24.4 per cent of the cases the clinical picture remained unchanged. 64.1 per cent showed a deterioration. Side-effects were gastric complaints, considerable leucocyte depression, oedemas, loss of hair, strumata, increase in transaminases, recrudescence of mycosis and pyoderma. In one case a state of confusion was observed. - Special criteria for the Imurek treatment are recommended. The necessity of a closed-meshed supervision of the patients is pointed out.

An assessment was made of a bioassay for a multiple sclerosis (MS)-associated agent claimed to cause a depression in the proportion of circulating polymorphonuclear neutrophils (PMN) in mice. Serum (1 sample), supernate from brain homogenates (four samples) and cerebrospinal fluid (four samples), and corresponding control materials, were tested under code by intraperitoneal injection into BALB/c mice. Results were plotted of proportions and absolute numbers of PMN over observation periods up to 2 weeks. Handling, injection and bleeding of mice did not significantly influence "baseline" counts of PMN. However, all samples from MS patients and controls caused an initial increase in PMN over 1--4 days, and then a later fall towards baseline. The claimed effect of MS materials in depressing counts of PMN in mice was not observed in these experiments, and variations in counts of PMN did not discriminate between samples from MS patients and controls.

The performance of patients with multiple sclerosis on selected psychological tests was examined to ascertain the usefulness of such examinations to diagnosis. Cognitive impairment was studied in relationship to disease-related factors, physician's identification of cerebral involvement, and psychological adjustment. The results indicate that half the subjects exhibited cognitive impairment. Levels of neurologic involvement, physical impairment, and depression were not predictive of cognitive impairment. Of the subjects who were judged on neurological examination to have intact mentation, half were actually impaired. Impaired cognitive functioning, which is often not detected through routine examination, may occur early in the disease. These deficits may represent manifestations of otherwise undetectable plaques in the subcortical white matter.

Thirty patients suffering from multiple sclerosis have been compared with 30 patients suffering from other chronic neurological diseases. The degree of disability was similar in these two groups. The patients with multiple sclerosis had experienced more episodes of severe depression both before and after the onset of neurological symptoms. The possible reasons for these episodes are discussed and it is concluded that in some patients serious affective disorder may be a presenting or complicating feature of multiple sclerosis.

Cognitive disorders associated with HIV infection may be due to focal lesions (lymphoma, toxoplasmosis, progressive multifocal leukoencephalitis, etc.), metabolic encephalopathy (e.g. hepatic insufficiency) or psychiatric disorders (depression). In the absence of such causes a "cognitive and motor syndrome associated with HIV infection" has been defined on clinical criteria (Working group of the American Academy of Neurology, 1991). This syndrome is not consistently associated with any specific lesion. Neither the multifocal encephalitis of HIV or CMV infection nor the diffuse leukoencephalopathy associated with HIV are the only causes. The existence of a neocortical neuronal loss has been suggested by several retrospective studies, but our prospective study has not shown cortical or subcortical atrophy. Measurement of neuronal density in Brodmann's areas 4,9 and 40 has not revealed a significant loss either global, by layer, or by column. The only constant lesion was gliosis of the cortex and white matter. Neuronal loss, therefore, is not indispensable to the occurrence of cognitive disorders in AIDS. The mechanism of dementia might be: dysfunction of cortical neurons (dendritic abnormalities, virus/neurotransmitter competition); subcortical dysfunction, as suggested by the high density of microglial nodules in that region; white matter lesions which could be due to abnormalities in the blood-brain barrier. The expression of cell adhesion molecules (VCAM-1, VLA-4, ICAM-1 and LFA-1) by endothelial cerebral cells is not significantly different in AIDS patients, demented or not, and in patients with multiple sclerosis. In contrast, the expression of VCAM-1 by astrocytes is significantly increased in demented AIDS patients compared with non demented ones.(ABSTRACT TRUNCATED AT 250 WORDS)

A variety of psychiatric disorders accompany multiple sclerosis (MS), affecting the spheres of cognition, affect, and personality. These disorders may be of primary and/or secondary nature, reflecting, respectively, neurologic damage and/or functional distress associated with a disabling disease. Evaluation of the nature, severity, and frequency of affective symptoms of MS patients is of importance to sensitize the treating physician to the possible need for specific psychiatric treatment. We conducted a prospective cross-sectional study assessing correlations of psychiatric symptomatology and the neurologic parameters of disease duration, disease activity (as expressed by the number of disease exacerbations per year), and disease severity (as measured by the Kurtzke Expanded Disability Status Scale [EDSS]) in 20 relapsing-remitting (RR)-MS patients. Patients were also evaluated by a semistructured psychiatric interview and the following rating scales: Hamilton Anxiety Scale (HAS), Hamilton Depression Scale (HDS), Hackett-Cassem Denial Scale, and Lubin Adjective Affective List. Results demonstrated a high prevalence of anxiety (90%) and to a lesser extent depression (50%) in RR-MS patients. Depression and anxiety were found to be associated with disease activity, but not with disease duration or severity. The mechanism of denial played a significant role in the psychiatric profile of the disease and was correlated with disease duration. We suggest that in RR-MS patients, psychiatric evaluation should also include assessment of defense and coping mechanisms, which in turn could guide specific individualized treatment.

In multiple sclerosis (MS) and its animal model experimental autoimmune encephalomyelitis (EAE) the cytokines tumour necrosis factor-alpha (TNF), lymphotoxin-alpha (LT), and interferon-gamma (IFN-gamma) are of central pathogenetic importance. A therapy capable of stopping neurological deterioration in MS patients is not yet available. Here, we report that rolipram, a selective type IV phosphodiesterase inhibitor, stereospecifically suppresses the production of TNF/LT and less strongly also IFN-gamma in human and rat auto-reactive T cells. Moreover, we show that rolipram is an effective treatment for EAE. Rolipram has extensively been studied in humans for the treatment of depression, but has not yet been marketed. The data presented here identify rolipram as potential therapy for multiple sclerosis and provoke the immediate initiation of clinical trials.
