While the exact cause of psoriasis is still not completely understood, the immune system and genetics are important in its development. Environmental factors can also play a role, for example an infection or emotional stress may trigger an episode of psoriasis, or worsen an existing outbreak.

While steering clear of some triggers may not be possible, others can definitely be avoided. Being able to identify what sets off, or aggravates your symptoms, can help you find a more effective treatment plan.


You may find the talk Psoriasis in 2013 , presented by Prof. Brian Kirby,  useful and help you to learn more about psoriasis.
