Does the nervous system play a role in developing psoriasis?

Yes, the nervous system can play a role in the development and exacerbation of psoriasis. Stress and emotional factors, which are mediated by the nervous system, can trigger or worsen psoriasis flare-ups. Additionally, neuroimmune interactions indicate that nerves can influence immune responses in the skin, contributing to the inflammatory processes associated with psoriasis. This connection highlights the complex interplay between the nervous system and skin health.
