摘要: Background The frequency and presentation of each the most common forms spinocerebellar ataxias (SCAs) varies widely. In case Americas, this diversity is particularly dynamic given additional social, demographic, cultural characteristics. Objective To describe regional prevalence clinical phenotypes SCAs throughout continent. Methods A literature search was performed in both MEDLINE LILACS databases. research broadened to include screening reference lists systematic review articles for studies. Investigations dating from earliest available through 2019. Only studies English, Portuguese, Spanish were included. We analyzed publications with genetically confirmed cases only, ranging robust samples epidemiological data reports series country or regions. Results Overall, SCA3 form Region-specific ranking vary. On other hand, region-specific phenotypic variations not consistently found based on analyzed, exception absence epilepsy SCA10 described a particular cluster South Brazil. Conclusion Systematic, multinational analyzing detail true frequencies across Americas as well distinct signs clues would be ideal look these potential variations.
