Prevalence of essential tremor: A door-to-door survey in Terrasini, Sicily
1994
As part of a door-to-door neuroepidemiologic survey, we investigated the frequency and distribution of essential tremor (ET) in a Sicilian municipality. During phase 1, we administered a screening instrument for tremor to 7,653 persons residing in Terrasini (Palermo province). During phase 2, neurologists evaluated those subjects who had screened positive. The diagnoses, based on specified clinical criteria, were reviewed to increase reliability across neurologists. We found 31 subjects affected by ET (17 men, 14 women); 11 patients (35.5%) reported a familial aggregation. The prevalence of ET as of November 1, 1987, was 405.1 per 100,000 for the total population, and 1,074.9 per 100,000 fo…
Prevalence of stroke: A door-to-door survey in three Sicilian municipalities
1996
As part of a door-to-door survey, we screened for stroke among the inhabitants of three Sicilian municipalities (n = 24,496 as of November 1, 1987). Neurologists then investigated those subjects suspected to have had a stroke. Diagnoses of first-ever strokes were based on specified criteria and were reviewed by an adjudication panel. We found 189 subjects who had experienced at least one completed stroke (180 definite, 9 possible); 15 strokes were hemorrhagic, 71 ischemic, and 103 uncertain. The prevalence (cases/100,000) was 771.6 in the total population and 1,893.6 in those aged 40 years or over. The prevalence increased steeply with age, was higher in men between 60 and 79 years, but was…
