Sale data for symptomatic medication against dementia from 66 countries and regions from 2008 to 2018 were analysed and stratified by income level (low\/middle\u2010income countries [LMICs], <jats:italic>n<\/jats:italic>\u00a0=\u00a027; high\u2010income countries [HICs], <jats:italic>n<\/jats:italic>\u00a0=\u00a037; regions, <jats:italic>n<\/jats:italic>\u00a0=\u00a02). The medication use volume was estimated by defined daily dose (DDD) per 1000 inhabitants per day (World Health Organization DDD harmonized the size, strength and form of each pack and reflects average dosing). Changes in medication use over time were quantified as percentage changes in compound annual growth rates (CAGRs).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Total symptomatic medication against dementia sales increased from 0.85 to 1.33 DDD per 1000 inhabitants per day between 2008 and 2018 (LMICs 0.094\u20130.396; HICs 3.88\u20135.04), which is an increase of CAGR of 4.53% per year. The increase was mainly driven by the LMICs (CAGR\u00a0=\u00a015.42%) in comparison to the HICs (CAGR\u00a0=\u00a02.65%). The overall medication use from 2008 to 2018 increased for all four agents: memantine (CAGR\u00a0=\u00a08.51%), rivastigmine (CAGR\u00a0=\u00a06.91%), donepezil (CAGR\u00a0=\u00a02.72%) and galantamine (CAGR\u00a0=\u00a00.695%). In 2018, the most commonly used medication globally was donepezil, contributing to 49.8% of total use volume, followed by memantine (32.7%), rivastigmine (11.24%) and galantamine (6.36%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>There was an increasing trend in the use of symptomatic medications against dementia globally, but the use remained low in LMICs.
