Statins are effective immunomodulators in vitro that merit evaluation as treatment for MS.

Sexuality and partnership have an important influence on the quality of life of every person and also on people with chronic disorders such as multiple sclerosis. The findings in literature show high evidence that people with multiple sclerosis experience high levels of sexual dysfunction, most of them with hypoactive sexual behaviour often associated with dissatisfaction in relationship, and also the partners seem to show lower sexual and partnership satisfaction. The most common problems in women are lack of sexual interest and decreased libido, often with problems in orgasmic capacity, while men report erectile dysfunction and also lack of sexual interest. The impact of the level of disability and duration of the illness remains unclear. Positive familial support can often help the patient in coping with the illness, nonetheless problems with changing roles and multiple-sclerosis-minimizing can improve the need of contacts to outstanding persons.

Since multiple sclerosis (MS) and autoimmune thyroiditis (AIT) are presumed to be of autoimmune origin the correlation of these two diseases is of special interest. The aim of this study was to determine whether there are differences in the prevalence of thyroid disease with special emphasis on AIT compared with MS and normal subjects and whether the presence of thyroid disease correlates with disability, disease course, age, and disease duration. 353 consecutive patients with clinically definite MS, without interferon-beta treatment and 308 patients with low back pain or headache were extensively examined for the presence of non-immune or autoimmune thyroid disease. We found a significantly higher prevalence of AIT in male MS patients (9.4 %) than in male controls (1.9 %; p = 0.03). The prevalence of AIT in female MS patients (8.7 %) did not differ from female controls (9.2 %). Hypothyroidism, caused by AIT in almost all cases, showed a tendency to be more severe and more often present in patients with MS. There was no association between relapsing-remitting and secondary progressive disease course of MS and the prevalence of AIT. MS patients with AIT were significantly older but did not differ in disease duration and expanded disability status scale (EDSS). Further studies are warranted, to see if there is a difference in sex-hormone levels between MS patients with and without AIT and healthy controls. Longitudinal studies comparing MS patients with or without AIT could show whether there is an influence of AIT on the disease course or progression.

The aim of this prospective open label study was to assess the efficacy of olanzapine for motor symptoms in Huntington's disease (HD). Olanzapine was administrated to nine patients with genetically confirmed HD in increasing doses until satisfactory clinical effect or the appearance of side effects. The patients were evaluated at baseline and after 14 days of treatment using the motor scale of the Unified HD Rating Scale (UHDRS). The patients improved significantly in most subscores of the UHDRS, including fine motor tasks, although some patients needed a rather high dose (30 mg per day). No adverse effects were reported by the patents spontaneously or were observed directly by the investigator. High-dose olanzapine seems to be useful in choreatic HD patients. A double blind, placebo-controlled trial appears warranted to definitively establish the symptomatic value of olanzapine in HD.
