- Genetic factors influence susceptibility to multiple sclerosis but the responsible genes remain largely undefined, association with MHC class II alleles being the only established genetic feature of the disease. The Nordic countries have a high prevalence of multiple sclerosis, and to further explore the genetic background of the disease, we have carried out a genome-wide screen for linkage in 136 sibling-pairs with multiple sclerosis from Denmark, Finland, Norway and Sweden by typing 399 microsatellite markers. Seventeen regions where the lod score exceeds the nominal 5% significance threshold (0.7) were identified-1q11-24, 2q24-32, 3p26.3, 3q21.1, 4q12, 6p25.3, 6p21-22, 6q21, 9q34.3, 10p15, 10p12-13, 11p15.5, 12q21.3, 16p13.3, 17q25.3, 22q12-13 and Xp22.3. Although none of these regions reaches the level of genome-wide significance, the number observed exceeds the 10 that would be expected by chance alone. Our results significantly add to the growing body of linkage data relating to multiple sclerosis.

Relationship of cognitive impairment to psychiatric symptoms in multiple sclerosis

Journal article (peer-reviewed)abstract
- Psychiatric and cognitive changes are common in patients with multiple sclerosis (MS), but their relationship has not received much attention. We studied the relationship between psychiatric symptoms and verbal memory, working memory, and mental speed in 78 patients with MS and 40 healthy control subjects using linear regression analyses. The MS group exhibited impaired performance on all cognitive tests. Apathy was associated with intrusions and depression with impaired memory and mental speed. The association between apathy and intrusions supports the hypothesis that lesions in frontal areas or frontal connections contribute to a specific neuropsychiatric syndrome in patients with MS.
