Presently four genes have been found to cause ALS Depression, anxiety and insomnia (Figs 1 and 2), SOD1, VAPB, SETX and ALSIN. At Depression occurs frequently at all stages of ALS as present mutations in the latter three genes appears to be well as insomnia (Dengler, 1999). Anxiety can become very rare and analysis is only performed in a scientific marked when respiratory insufficiency occurs. The four mostly used antidepressants in ALS are amitriptyline, Since 1993 some 119 mutations have been found in sertraline, fluoxetine and paroxetine. Amitriptyline has the SOD1 gene with five different modes of inherit- the best therapeutic effect and the lowest costs. For ance (Fig. 2; http://www.ALSOD.org; Andersen et al., insomnia in ALS, amitriptyline and zolpidem are the 2003). The most frequent mutation is the D90A, most commonly used medications (Forshew and which in most European countries is inherited as a Bromberg, 2003). There are no systematic studies on recessive trait with a characteristic slowly progressing anxiolytics in ALS, but oral diazepam or sub-lingual phenotype (Andersen et al., 1996).
