“…Fairly consistent results emerge if one tallies the results of group comparison studies. Relative to normal controls or non-brain-damaged patient controls, MS patients have been found to be impaired in seven studies (Elpern et al, 1984;Heaton et al, 1985;Jambor, 1969;Parsons et al, 1957;Peyser, Edwards, Poser, & Filskov, 1980;, with only one negative study (Ross & Reitan, 1955). Four studies have compared MS patients to groups of mixed braindamaged patients; none of the four studies found statistical differences between these two groups (Goldstein & Shelly, 1974;Ivnik, 1978b;Ross & Reitan, 1955).…”

“…A relationship between test performance and disability (assessed with the Kurtzke DSS) has been observed by Parsons et al (1957), although negative findings have been reported by others (Peyser, Edwards, Poser, & Filskov, 1980); . A recent study by Heaton et al (1985) addressed the role of disease course in influencing performance on conceptual reasoning tasks.…”

“…Using the Wechsler scales, several studies have compared the performance of MS patients to that of various control groups, including normals (Jambor, 1969, Parsons, Stewart, & Arenberg, 1957Reitan, Reed, & Dyken, 1971), brain-damaged patients (Goldstein & Shelly, 1974;Ivnik, 1978b, Jambor, 1969, non-brain-damaged, neurologically disabled patients (Jambor, 1969), and psychiatric patients (Goldstein & Shelly, 1974;Jambor, 1969). These studies are noteworthy for the lack of significant mean group differences both for the IQ and individual subtest scores.…”

Multiple sclerosis (MS) is a relatively common, chronic progressive neurological illness affecting individuals primarily in the third and fourth decades of life. Autopsy studies indicate that the disease preferentially attacks white matter throughout the CNS, including the cerebral hemispheres. This article reviews the current state of knowledge regarding cognitive dysfunction in MS and relates these findings to neuropathological changes. The view that affective disturbance may also result from cerebral demyelination is presented, along with a brief discussion of MS as a prototype "subcortical" dementia. Finally, methodological problems intrinsic to the study of MS are presented, and suggestions for future research are made.

“…Impairment of non-verbal skills (Reitan el al. 1971;Ivnik, 1978), memory (Grant et al 1984;Rao et al 1984) and abstracting ability (Parsons et al 1957) are the main features. Recently interest has also been directed to attentional abnormalities (Filley et al 1989) and slowing of cognitive processing (Rao et al 1989 a).…”

Cognitive abnormalities in multiple sclerosis: a psychometric and MRI study

1991

View full text Add to dashboard Cite

SYNOPSISThis study reports the cognitive abnormalities of a group of 58 patients with definite multiple sclerosis (MS). The psychometric functions measured were: '1Q deficit', verbal and visual memory, abstracting ability, visual and auditory attention and naming ability. The presence of brain pathology was investigated using magnetic resonance imaging (MRI). A group of 46 physically disabled controls without significant brain disease was used for comparison. Normative MRI data were obtained from a group of 40 normal volunteers. The psychometric performance of the MS group was compared to the previously reported findings in patients with clinically isolated syndromes.MS patients had widespread cognitive deficits sparing naming ability and affecting verbal memory less severely than other intellectual functions. The overall performance on psychometric tests was related to the severity of the MRI abnormalities and to the duration of the illness, but was not significantly influenced by the presence of psychiatric morbidity or the degree of physical disability. Patients with clinically isolated syndromes occupied an intermediate position between MS patients and disabled controls in terms of cognitive and MRI abnormalities.
