Clarivate Epidemiology’s coverage of major depressive disorder (MDD) (DSM-5) comprises epidemiological estimates of key patient populations in 45 countries worldwide. We report the prevalence of MDD (DSM-5) for each country, as well as annualized case counts projected to the national population.

Most patient populations are forecast over a period of 20 years for the major mature pharmaceutical markets of the United States, Europe, and Japan. In addition to forecasting prevalent patient populations, we estimate the number of drug-treatment opportunities in specific lines of therapy in the major mature pharmaceutical markets.

Clarivate Epidemiology’s MDD (DSM-5) forecast will answer the following questions:

  • Of all people with MDD (DSM-5), how many in each of the major mature pharmaceutical markets have been formally diagnosed?
  • Of all people diagnosed with MDD (DSM-5), how many in each of the major mature pharmaceutical markets are drug-treated?
  • How will demographic trends, such as population aging and improving life expectancy, affect the epidemiology of MDD (DSM-5) over the forecast period?

All forecast data are available on the Clarivate Insights Platform in tabular format, with options to download to MS Excel. All populations are accompanied by a comprehensive description of the methods and data sources used, with hyperlinks to external sources. A summary evidence table generated as part of our systematic review of the epidemiological literature is also provided for full transparency into research and methods. In addition, we provide a graph depicting the patient flow between or within different disease states for the major mature pharmaceutical markets. These patient-flow diagrams are provided at the regional level but may be requested for any specific country or forecast year.

Clarivate Epidemiology forecasts the following MDD (DSM-5) patient population:

  • Total prevalent cases.

Note: Coverage may vary by country.
