“…The higher numbers in our study, compared to those previously reported for the same province in the eighties [20,21], can also be explained by both the methodology employed with comprehensive case ascertainment and the higher grade of sanitary development (MR available from 1991). Also, the longer survival of MS patients may play a role.…”

Objectives: To determine the prevalence and incidence of multiple sclerosis (MS) in the city of Las Palmas (Canary Islands, Spain), geographically belonging to north-western Africa, but with European ancestry. Methods: This population-based survey was conducted for a period of 5 years (1998–2002) in a Sanitary District of Las Palmas city (28° 20’ N), with a population of 82,623 inhabitants. Multiple sources were periodically investigated for case ascertainment. Patients with definite and probable MS were included. Results: Sixty-four patients with MS were identified on prevalence day, December 31, 2002. According to Poser’s criteria the crude prevalence rate was 77.5 per 100,000 (95% CI: 59.7–98.9). This rate decreased to 73.8 (95% CI: 56.5–94.8) according to McDonald’s criteria. Age-adjusted rates for the world and European standard populations were 61.6 (95% CI: 47.1–78.9) and 70.6 (95% CI: 55–89), respectively. Prevalence was higher for women aged 25–44 years. In 17 patients onset of MS occurred within the study period. Average annual incidence was 4.1 per 100,000 (95% CI: 2.4–6.6). Conclusions: The prevalence and incidence rates in Las Palmas city are close to those reported from Continental Spain and other countries of southern Europe with similar social and ethnic background. These results highlight the role of racial-ethnic factors in the genesis of MS.

“…Both studies were performed in a short time period (1 year) and evaluated mainly hospitalized patients [20,21]. A more recent survey conducted in La Palma Island (81,507 inhabitants), using multiple case-ascertainment sources, yielded a higher rate (42 cases/100,000 inhabitants), still lower than that in the Iberian peninsula [22].…”

“…This prevalence was higher than that found on other islands in the Archipelago in previously published studies and in which only hospital records were used [11,12]. The clinical features of the disease determine that its prevalence is lower than its real incidence as most benign cases are not detected or they are detected late.…”

“…In the Canary Islands, two prevalence studies of MS have been published [11,12]. In the first study carried out on the Island of Gran Canaria, a prevalence of 6.2 cases /100,000 was obtained [11], and later on the Island of Lanzarote, it was 15/100,000 [12].…”
