Age‐ and sex‐stratified incidence rates of uncommon dementia subtypes are imprecise and scarce. Methods We used data from 7357 newly diagnosed individuals aged between 30.6 and 101.0 years from the Registry of Dementia of Girona during 2007‐2016 to determine the incidence rates of uncommon dementia subtypes stratified by sex and age groups and to describe their clinical characteristics. Results Uncommon dementia subtypes were classified according to their etiology. The incidence rate of uncommon dementia subtypes was 27.8 cases per 100,000 person‐years for those aged 30 years and older, 3.7 cases per 100,000 person‐years for people aged less than 65 years, and 110.9 per 100,000 person‐years for those aged 65 years and older. Age, sex, dementia severity, and medical comorbidities were different depending on the dementia subtype. Discussion There are differences in the incidence rates and the demographic and clinical characteristics among uncommon dementia subtypes for age and sex groups.
