Incidence and mortality rates of amyotrophic lateral sclerosis (ALS) vary between countries, and in some studies appear to increase over time. We performed a study to assess ALS incidence in a northern Italy area over a 10-year period. We identified the new cases of probable or definite ALS diagnosed among residents in Reggio Emilia province between 1996 and 2005 using several sources of data, such as death certificates, clinical records, hospital discharge registers and drug prescriptions. A total of 94 newly-diagnosed patients were identified. The average standardized incidence in the period was 2.0 and 1.0 cases/100,000/year, using the Italian and the world population, respectively, as reference. There was no variation in rates over time. Incidence was 1.3 in males and 0.8 in females. No cases were observed in patients under 35 years of age. Incidence increased after the age of 55 years, reaching a peak in the group aged 70-74 years and declining thereafter. We concluded that ALS incidence in this population was similar to that observed in other Italian regions and European countries, and no variation was identified during the study period.
