The crude and European population standardized incidences of ALS were as high as 3.19/100 000 person‐years of follow‐up (95% CI 2.81–3.56) and 2.58/100 000 person‐years of follow‐up (95% CI 2.27–2.89) respectively. Median age at onset was 70.8 years (interquartile range 63.1–77.1). The standardized sex incidence ratio (male/female) was 1.3 overall, but 1.1 under the age of 65 years, 1.7 between 65 and 75 years and 1.9 above 75 years. The exhaustiveness of the register has been estimated at 98.4% (95% CI 95.6–99.4) by capture–recapture analysis.</p> </sec> <sec id="ene12474-sec-0004" sec-type="section"> <title>Conclusion</title> <p>It was possible for the first time in France to monitor accurately the incidence of ALS over a long time period.
