title: Amyotrophic lateral sclerosis in Nova Scotia.
abstract: A study of ALS incidence in Nova Scotia for a ten year period was carried out with the cooperation of neurologists, neurosurgeons, physiatrists and major medical hospitals. Over a ten year period 161 cases occurred, an incidence of 1.95 per 100,000 population in a province with a population of 825,000. There was an increase in incidence over the ten year period, with an incidence for the first five years of study of 1.50 per 100,000, and 2.40 per 100,000 for the latter five years. The peak incidence in 1981-1982 was 2.66 per 100,000. Although this is the highest incidence in community studies of ALS (excepting the unusual circumstances in Guam), it may reflect the realistic incidence of ALS rather than an unusual focus, as ascertainment was likely greater than in many other studies. The more significant finding is the suggestion of an increasing incidence, as noted in other studies in the U.S., England and Israel.
