Psoriasis is estimated to affect about 125 million people worldwide, and it comes with more than skin symptoms. Adults with psoriasis face a standardized mortality ratio of 1.0 to 1.6 and a higher risk of depression, while only a fraction reach top treatment goals like PASI 90 in the first few months. Even when biologic therapy performs well in trials, real world coverage is far from matching the burden, so the gap between prevalence and outcomes is worth looking at closely.
Key Takeaways
- Patients with psoriasis have increased mortality risk; standardized mortality ratio estimates range from 1.0 to 1.6 across studies
- Psoriasis is associated with a 1.5–2.0x increased risk of depression compared with controls (meta-analytic estimate range)
- 125 million people worldwide are estimated to have psoriasis
- 17% of psoriasis patients have scalp involvement
- 16.4% of adults with psoriasis had moderate-to-severe disease severity (PASI ≥10)
- 1.2% of adults in the UK have psoriasis
- 30% of psoriasis patients develop psoriatic arthritis
- 12% of patients with psoriasis achieve PASI 90 with systemic/biologic therapy within 12–16 weeks in trial settings (meta-analytic estimate)
- 80% of patients treated with adalimumab reach PASI 75 by week 16 in pivotal trials
- 67% of patients treated with ustekinumab reach PASI 75 by week 12–16 in pivotal trials
- The global psoriasis drugs market is projected to reach $XX.X billion by 2030 (forecast range)
- The global psoriasis therapeutics market is projected to reach $XX.X billion by 2032 (forecast range)
- The global psoriasis treatment market was valued at $XX.X billion in 2023 (market sizing publication)
- Worldwide sales of secukinumab were $4.4 billion in 2023 (company annual report figure)
- Outpatient costs represented 83.5% of total psoriasis-related healthcare costs (US estimate)
With up to 125 million people affected, psoriasis raises mortality and depression risk and many patients still need effective systemic treatment.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
