“…Only in the SP phenotype did the impairment result in naming dysfunction. These results are partially in line with the findings of a previous study (Laatu et al, 2001) in cognitively deteriorated MS patients, which revealed deficits in familiarity detection in a task that used real objects (coherent shapes) and unreal objects (non-coherent shapes). The findings of the present study suggest that deficits in familiarity detection can also be present in patients without cognitive dysfunctions.…”

“…The findings of the present study suggest that deficits in familiarity detection can also be present in patients without cognitive dysfunctions. This discrepancy is probably due to the differences between our tasks, which considered only correct answers, and those of Laatu et al (2001), which took into account both correct answers and reaction times. In the cited study (Laatu et al, 2001), as in the present one, patients without cognitive deficits were found to perform worse than healthy comparison adults if the comparison considered only correct answers.…”

“…Using an extensive visuoperceptual neuropsychological battery, Vleugels et al (2001) showed that speed of information processing correlates with MS patients' visuoperceptual neuropsychological task performances and may be related to a magnocelluar pathway dysfunction. Moreover, Laatu et al (2001) investigated different stages of object identification: shape recognition, comparing objects with familiar representations in long-term memory, semantic categorization and naming. They compared the performances of MS patients with and @ C I C E d i z i o n i I n t e r n a z i o n a l i without cognitive impairment and healthy controls.…”

SummaryThe aim of this research was to study cognitive dysfunctions in multiple sclerosis (MS) by exploring subtle cognitive tasks, usually not included in the standard neuropsychological assessment. We wished to investigate whether it is possible to identify object decision deficits in MS patients without evident cognitive impairment; secondary objectives were to understand whether these deficits can be detected in the early stages of the disease and whether there are differences related to different phenotypes. Participants were divided into four groups: (a) 12 patients with early relapsing-remitting MS [ERR]; (b) 14 with late relapsing-remitting MS [LRR]; (c) 10 with secondary progressive MS [SP]; (d) 36 healthy controls [HCs]. All participants performed a series of experimental tasks: an object decision task (recognition of chimeric and real figures) and naming and visual discrimination tasks. Our results suggest that object decision disorders are detectable in patients without overt cognitive impairments and that performances on these tasks are related to phenotypes. On the other hand, the Chimeric Figures task is not appropriate for identifying cognitive dysfunctions in early MS.

The aim of this chapter was to introduce the contents of neuropsychological assessment in multiple sclerosis, which should include the functional evaluation of cognitive domains, the psychopathology of personality, levels of depression, and the assessment of psychosocial aspects and quality of life with multiple sclerosis. Further, the most commonly used neuropsychological diagnostics are described. The chapter hopes to draw attention to the importance of neuropsychological assessment which should be a part of neurological diagnostics and therapy, including rehabilitation and psychotherapy.

“…Multiple sclerosis can cause difficulties with recognition and identification of objects. The problems include impaired recognition of shape, together with difficulties with identification and naming 91 and can result from occipito-temporal demyelination. 92 Visuospatial problems are also common.…”
