Major Depressive Disorder (MDD) Epidemiology Insights
Thelansis’s “Major Depressive Disorder (MDD) Epidemiology Insights and Forecast Report – 2020 To 2040″ provides an analysis of disease burden, characterized by disease definition, prevalence, incidence, diagnosed cases, severity, comorbidities, and clinical manifestations. Potential patient flow dynamics in disease burden are driven by shifts in demographic indicators and their correlation with age and gender distribution over time. Changes in the reported cases and long-term survival of patients may depend on diet, lifestyle, comorbid conditions, and the availability of interventions or therapies.
Major Depressive Disorder (MDD) Overview
Major Depressive Disorder (MDD) is a common and serious psychiatric condition characterized by persistent low mood, loss of interest or pleasure in daily activities, and functional impairment lasting at least two weeks. It affects individuals across all age groups and arises from a complex interplay of genetic, neurobiological, psychological, and environmental factors. Symptoms may include fatigue, sleep disturbances, appetite changes, feelings of guilt or worthlessness, difficulty concentrating, and in severe cases, suicidal thoughts or behaviors. Diagnosis of MDD is clinical, based on standardized criteria such as those in the DSM-5, and requires exclusion of other medical or psychiatric conditions. Treatment typically involves a combination of psychotherapy—most commonly cognitive behavioral therapy—pharmacologic interventions like selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs), and lifestyle modifications.

- Others*: regular updates, customizations, epidemiologist support
*As per Thelansis’s policy, we ensure that we include all the recent updates before releasing the content. Countries, subpopulations, and years of forecast can be customized as per client requirements.
Key business questions answered:
- 20-year historical and forecast data (2020–2040)
- Disease definition based on globally accepted and latest criteria (e.g., ICD-10 codes)
- Granular patient population coverage by year and geography
- Detailed segmentation by age, gender, subpopulations, comorbidities, line of therapies, etc.
- Patient funnels
- Country comparisons
- Relevant clinical variables (e.g., staging/classification/severity)
Insights driven by robust research and estimates:
- Published literature (e.g., peer-reviewed journal articles, registries, national surveys)
- Primary market research with KOLs
- RWD analysis using claims and EHR datasets
- Proprietary mathematical models (e.g., incidence-survival model; incidence- recurrence/progression-survival model)
