Abstract

A questionnaire with 54 relevant questions was studied in 100 ALS patients and 100 age and sex matched control cases. The findings were discussed in relation to 7 questionnaires in the literature. No differences were found between ALS patients and controls. Especially the increase of frequency of gastrointestinal operations, previous poliomyelitis, toxic metal exposure frequency, antecedent fractures and excess milk drinking as described in the literature were not confirmed.
